Y
Trechol –The Dominant Hills of Wales – Significant Name Changes
Y
Trechol –The Dominant Hills of Wales are the Welsh P30 hills whose
prominence equal or exceed half that of their absolute height, accompanying the
Dominant list is a sub list entitled The
Lesser Dominant Hills of Wales with
the criteria for this sub category being those additional Welsh P30 hills whose
prominence is between one third and half that of their absolute height. The list commenced publication on Mapping Mountains on 03.012.15 with its Introduction giving details to its compilation
and criteria, with Change Registers also created for the Dominant and the
Lesser Dominant category.
The list is authored by Myrddyn
Phillips and the posts that have appeared on Mapping Mountains detailing the
significant name changes to the Dominant and Lesser Dominant list appear below
presented chronologically in receding order.

Cae Felin Wynt (SS 683 954) - 35th significant name change
Summit Relocations post for Cae Felin Wynt
There has been a Significant Name Change to a hill that is listed in the 100m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, its location, the drop and status of the hill confirmed by LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the two listings that this name change applies to are:
100m Twmpau - Welsh hills at or above 100m and below 200m in height with 30m minimum drop, with an accompanying sub list entitled the 100m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 100m and below 200m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.
Y Trechol – The Dominant Hills of Wales – Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height. The list is authored by Myrddyn Phillips with the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3rd December 2015.
The hill is adjoined to the Fforest Fawr group of hills, which are situated in the western part of South Wales (Region C, Sub-Region C2), and it is positioned with the B5444 and the A4217 roads to its west and the Crymlyn Bog to its east, and has the city of Abertawe (Swansea) towards the west south-west.
The hill originally appeared in the 100m P30 list on Geoff Crowder’s v-g.me website under the name of Cefn Hengoed, which is a name that appears close to the summit of this hill on contemporary Ordnance Survey maps.

During my early hill listing I paid little regard to name placement on the map, or the meaning of names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate. And as I have been unable to substantiate the name of Cefn Hengoed for that of the hill I examined the Tithe map.

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map. The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.
 |
| Extract from the Tithe map |
The enclosed land where the summit of this hill is situated is given the number 1115 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The land where the summit of this hill is situated is named as Cae felin wynt in the apportionments, with the details on the Tithe map appearing in the parish of Llansamlet and in the county named as Glamorgan.
 |
| Extract from the apportionments |
Therefore, the name this hill is now listed by in the 100m Twmpau and Y Trechol – The Dominant Hills of Wales is Cae Felin Wynt, and this name was derived from the Tithe map.

The hill is adjoined to the Carneddau group of hills, which are situated in the north-western part of North Wales (Region A, Sub-Region A1), and it is positioned with the B5106 road to its west and the Afon Conwy (River Conwy) to its east, and has the town of Conwy towards its north.
The hill originally appeared in the 100m P30 list on Geoff Crowder’s v-g.me website under the directional name of Iolyn Park North East Top, with an accompanying note stating Name from camp site to the South-West.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day. My preference was to use farm names and put Pen, Bryn or Moel in front of them, or as in this instance use a directional name based on what I presumed was the name of a camp site toward the south-west. This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

I visited this hill along with Aled Williams and leaving the summit we met the local farmer who had driven up a near track to find out what we were doing. Having explained our interest in surveying and upland place-names, Awen Roberts told us that the hill does not have an individual name but the two fields that vie for the high point of this hill are known as Cae Doctor (67.0m at SH 30425 39978) and Cae Myllt (66.9m at SH 30421 39985), with the former the higher and being named as such as a doctor lives close to its field boundary.

This hill was listed with a 64m summit height which is positioned at SH 295 266 and appeared as a spot height on the Ordnance Survey 1:25,000 Explorer map. The details for this hill were reassessed when the Ordnance Survey Interactive Coverage Map hosted on the Geograph website became available online, and this map has a 66m spot height at SH 299 270 which is adjoined to the hill to the north-east, which only has an uppermost 60m ring contour on the 1:25,000 Explorer map. Therefore the summit position of the listed hill was relocated and its drop value increased accordingly, with the Interactive Coverage Map also giving the south-westerly hill a second 64m map heighted summit, and LIDAR analysis confirms that the north-easterly of these two hills is the higher.

During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day. My preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance use the name of a near village and put the word Bryn in front of it. This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

I visited this hill along with Aled Williams and on our way back to the car I took the opportunity to call at one or two houses hoping to be directed toward the local farmer. A woman was on the drive of the second house we called out and she was the partner of Wyn Roberts, who had been on his quad bike in an adjacent field when we were on the summit. Having explained our interest in the hill’s name we were directed down the road to where Wyn would soon re-appear on his quad bike after checking on his herd of cows.
After flagging Wyn down and introducing ourselves he explained that the hill we had visited is known as Yr Orsedd and the lower hill to the south-west, that was first listed as the qualifying P30 is known as Bryn Tŷ Newydd.

Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Yr Orsedd, and this was derived from local enquiry.

Y Trechol – The Dominant Hills of Wales – Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height. The list is authored by Myrddyn Phillips with the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3rd December 2015.
The hill is adjoined to the Mynydd Penlle’rcastell group of hills, which are situated in the western part of South Wales (Region C, Sub-Region C1), and is positioned with the A483 road to its immediate west and the A48 and M4 to its north, and has the village of Penlle’r-gaer to its north.

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map. The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

| Extract from the Tithe map |
The enclosed land where the summit of this hill is situated is beside a raised field boundary, with land either side of this considered of equal height, and the prioritised summit position is given the number 2928 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The land where the summit of this hill is situated is named as Cae ddu main in the apportionments, with the details on the Tithe map appearing in the parish of Llangyfelach and in the county named as Glamorgan.

This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.
As the summit of this hill comprises bounded land the details for it were examined on the Tithe map, and the upper section of the hill which now comprises one field, used to comprise two, with the boundary between each showing as a slight elevation on LIDAR. This boundary although old, is not ancient, and is a relatively recent man-made construct.
The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.

The two upper fields at the time of the Tithe are orientated north-west – south-east of one another. The enclosed land where the north-westerly field is situated is given the number 2183 on the Tithe map, whilst the south-easterly field is given the number 2212 on the Tithe map, these can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The north-westerly field is named Bryn Cefn Tŷ and the south-easterly field is named Cae Bryn in the apportionments, with the details on the Tithe map appearing in the parish of Aber-erch and in the county named as Caernarfonshire.

After visiting the hill I took the opportunity to call at the farm of Penychain which is situated to the immediate north of the hill, and met Griffith Owen; the local farmer, who is now aged 76 and has lived at this farm for many years. Griffith told me that the headland to the south-east of this hill’s summit is known as Penychain and that the hill is known as Bryn, with some locals also knowing it as Bryn Penychain to differentiate this generic name from other hills in the vicinity that are also known as Bryn.
Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Bryn, and this was derived from local enquiry.

The hill is the highest in its own group, therefore it is adjoined to the Mynydd Penlle’rcastell range of hills which are situated in the western part of South Wales (Region C, Sub-Region C1), and it is positioned with the Afon Llwchwr (River Loughor) to its west and the A 474 to its north and east, and has the town of Rhydaman (Ammanford) to its north-west.
The hill appeared in the original Welsh P30 lists under the 300m height band on Geoff Crowder’s v-g.me website, under the name of Mynydd y Betws, which is a name consistently applied to the northern part of this hill on Ordnance Survey maps.

During my early hill listing I paid little regard to name placement on the map, or the meaning of names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate.
 |
| Extract from the Ordnance Survey 1:50,000 Landranger map |
There are three names that are consistently applied to the upper part of this hill on Ordnance Survey maps, these are:
Mynydd y Betws, which appears on the northern part of the hill.
Penlle’rcastell, which appears close to its summit.
Mynydd y Gwair, which appears on the southern part of the hill.
Having these three names consistently appearing on Ordnance Survey maps for the upper part of this hill indicates that there is a boundary between where these names are applicable to. Therefore, the Tithe map was consulted.
The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales. However, in this instance the upper part of this hill is open and it is named Mynydd Penlle’rcastell on the Tithe map.

This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map. The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

| Extract from the Tithe map |
The enclosed land where the summit of this hill is situated is given the number 1220 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The land where the summit of this hill is situated is named as Parkyfedwen [sic] in the apportionments, with the details on the Tithe map appearing in the parish of Llangunnor and in the county named as Carmarthen.

During the initial compilation of the Dominant list I made a number of place-name enquiries for qualifying hills, including this one. I was put in contact with Elin Evans and Julian Fry, at the time of our conversation Elin was a school teacher and Julian a web master for a site concentrating on Llanychaer, this being the small community where they lived. Elin’s grandfather grew up at Penlan (SM 997 333), and her parents; John and Rhian Evans lived in the bungalow adjoined to the farm of Cronllwyn (SM 986 348), therefore her family have lived beside this hill for at least three generations.
On the day I phoned, Elin’s parents were upset as one of their sheep dogs had been put down, therefore Julian offered to speak with John and Rhian at an opportune moment, and he later did so and phoned me with details relating to this hill and its name. The name given Julian for this hill by Elin’s parents; John and Rhian Evans is Pen Twmp.
Therefore, the name this hill is now listed by in the 200m Twmpau and Y Trechol – The Dominant Hills of Wales is Pen Twmp, and this name was derived from local enquiry.

On occasion I also used a directional name based on supplanting the name of a near hill and adding a directional component to the name. This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

When visiting this and adjoining hills I met a number of local farmers, including Joanne Redman on the summit of Coed Uchaf (SH 649 055), Joanne was on her quad bike taking photos of her father’s farm of Nant-y-mynach (SH 644 048), we talked about this and other hills and Joanne suggested that I should contact her father; Tomos Lewis, whose telephone number she kindly gave me.
The following day I contacted Tomos and two days later then visited him, Tomos is aged 60 and a Welsh speaker, and has lived at Nant-y-mynach for 54 years, having moved there from the council houses in Abertrinant when aged six. During our conversations Tomos proved very knowledgeable and gave me many hill names that do not appear on any Ordnance Survey map, and one of them was the name of this hill, which Tomos called Bird’s Rock, we then concentrated on the four individual prominence hills which are all positioned close to one another and in the vicinity of the hill named Bird’s Rock / Craig yr Aderyn on contemporary Ordnance Survey maps, and Tomos was of the opinion that the two main hills are both a part of the overall hill known as Craig yr Aderyn.

During the conversation with Tomos I mentioned that I planned to call at Gesail (SH 641 063) which is the farm directly under this hill to its south-west and Tomos told me that the farmer is named Dafydd Jones.
When I visited Gesail, Dafydd and his son were busy in a large barn spraying sheep, we went outside to talk about the hills that from this vantage point rose directly above the farm, and Dafydd explained that although he had only lived at this farm for a few years his family are local to the area and that he knows all the hills above his farm as a part of Bird’s Rock.

As a directional name only adds an invented component to the name of the hill, this is dispensed with in favour of the name that is in use locally, with the caveat that the Welsh name for this hill is prioritised over its English equivalent, which for listing purposes is standard practice.
Therefore, the name this hill is now listed by in the 200m Twmpau and Y Trechol – The Dominant Hills of Wales is Craig yr Aderyn, and the hills known by this name were derived from local enquiry.
The full details for the hill are:

Foel Cocyn (SH 624 042) - 15th significant name change
Survey post for Foel Cocyn
There has been a Significant Name Change to a hill that is listed in the Y Trichant and Y Trechol – The Dominant Hills of Wales, with the summit height being confirmed by a Trimble GeoXH survey which took place on the 14th May 2018, and the drop of the hill being confirmed by LIDAR analysis conducted by Myrddyn Phillips.
The criteria for the listings that this name change applies to are:
Y Trichant – Welsh hills at or above 300m and below 400m in height that have 30m minimum drop. The list is authored by Myrddyn Phillips and the Introduction to the list and the re-naming and publication history of it was published on Mapping Mountains on the 13th May 2017.
Y Trechol – The Dominant Hills of Wales – Welsh P30 hills whose prominence equal or exceed half that of their absolute height. The list is authored by Myrddyn Phillips with the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3rd December 2015.
The hill is adjoined to the Tarennydd range of hills which are situated in the south-western part of North Wales (Region A, Sub-Region A3), and it overlooks the B 4405 road and the Afon Fathew to the south-east and the Afon Dysynni to the north-west, and has the small community of Dolgoch to its east and Bryn-crug to its south-west.

| Foel Cocyn (SH 624 042) |
The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name of Ffridd Cocyn. During my early hill listing I paid little regard to name placement on the map, or the meaning of names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate, and although the name of Ffridd Cocyn has been consistently presented on Ordnance Survey maps, it was enquiries with a number of local farmers who gave the name of Foel Cocyn for this hill.

When visiting this and adjacent hills I was fortunate to speak with a number of local farmers including Edward Cook of Perfeddnant (SH 628 055), who I met on the upper slopes of this hill, Edward was out on his quad bike with a colleague and two sheep dogs and I was surprised when he gave me the name of Foel Cocyn for this hill as I had accepted the map name for many years. I asked if this should be Ffridd Cocyn and Edward replied ‘no, I know it as Foel Cocyn’.

I descended from this small grouping of hills to Llanerch-goediog (SH 640 050) and met Stephen Jones who has lived at this farm all of his life outside of three years he spent at university. When asked about this hill Stephen said that it’s known as Cocyn, he later referred to it as Foel Cocyn, I again asked if this should be Ffridd Cocyn, and was told that it’s a foel.

| Stephen Jones of Llanerch-goediog |
My route continued north-east from Stephen’s farm and I was fortunate to meet Joanne Redman at the summit of the next hill, she helped me with its name which will be documented in a forthcoming Significant Name Changes post, and suggested that I should contact her father; Tomos Lewis who lives and farms from Nant-y-mynach (SH 644 048), she then kindly gave me his telephone number.
The following day I phoned Tomos and two days later then visited him. Tomos has lived in this area all of his life having been brought up in one of the council houses in Abertrinant and has lived at Nant-y-mynach since the age of six. He gave me the name of Foel Cocyn for this hill during our telephone conversation and later confirmed this name when we met, I asked about the name of Ffridd Cocyn and he said that ‘we’ve always known the top as Foel Cocyn’.

The term ffridd is usually given to land that is enclosed and is lower than the mountain, or mynydd land adjoined to a farm, both are associated with the cynefin naming system, details relating to these are given below:
Many Welsh hills comprise bounded land that is separated either by a fence or wall; these boundaries indicate land that is adjoined to different owners or tenants. These land boundaries have usually been in place for centuries and in the uplands of Wales they are referred to as the cynefin, or sheep-walk in English.
The sheep-walk is an English term given to enclosed land that is apportioned to a specific farm. The Welsh term for this land is cynefin, which can be literally translated as habitat, as in that for the sheep. The cynefin usually takes in land that is known as the mountain land of the specific farm, therefore the name given to this enclosed land is usually that of the name of the farm prefixed with the word mynydd (mountain), this land is usually given over for sheep grazing, hence the term sheep-walk. When Ordnance Survey maps are examined one can find many examples where this form of cynefin naming system exists, with farms situated in valley’s having their name given to high mountain land and prefixed with the word mynydd.
The bounded land given over to specific farms also takes in middle ground between the higher mountain land and the lower pasture land of the valley, this is known in Welsh as the ffridd and can take in a variety of habitats including heath, moor, grassland, woodland and high pasture. Again, when Ordnance Survey maps are examined one can find many examples of names prefixed with the word Ffridd, and its apportionment to a specific hill is dependent upon where the bounded land is situated and referring to the Tithe maps for confirmation is then advised.
It is the cynefin naming system that usually results in a hill being known by different names in opposing valleys, as in many instances the upper bounded land meet at the watershed on top of the summit ridge and therefore the same hill would be known by two different names, each name a part of a different farm’s cynefin.
When visiting these farmers I asked if there was a farm named Cocyn in the area which would substantiate the use of the word ffridd in relation to this hill, and was told there wasn’t, with Edward Cook telling me that the word cocyn refers to the small hummocks on the side of the hill.
Although the name of Ffridd Cocyn has been consistently given on Ordnance Survey maps in relation to this hill, it seems this name is either no longer used in the local community or it was never used and that the transcript of this hill’s name was incorrectly given by Ordnance Survey as Ffridd instead of Foel.
Even if the name of Ffridd Cocyn was once used locally, this would refer to enclosed land incorporating a field, whereas the name of Foel Cocyn refers to the hill and not necessarily to just an enclosed field.
Therefore, the name this hill is now listed by in the Y Trichant and in Y Trechol – The Dominant Hills of Wales is Foel Cocyn, and this was derived from local enquiry.
The full details for the hill are:

Coed Hyrddyn (SJ 200 439) - 14th significant name change
Survey post for Coed Hyrddyn
There has been a Significant Name Change to a hill that is listed in the 200m Twmpau and Y Trechol - The Dominant Hills of Wales, with the summit height, drop and status of the hill being confirmed by a Leica GS15 survey which took place on the 7th February 2013, with a subsequent Trimble GeoXH 6000 summit survey taking place on the 5th May 2018.
The criteria for the listings that this name change applies to are:
200m Twmpau – All Welsh hills at or above 200m and below 300m in height that have 30m minimum drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.
Y Trechol – The Dominant Hills of Wales – Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height. The list is authored by Myrddyn Phillips with the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3rd December 2015.
The hill is adjoined to the Moel y Gamelin range of hills which are situated in the north-easterly part of North Wales (Region A, Sub-Region A2), and it overlooks the A 542 road and the Eglwyseg River to its east and the A 5 road, Llangollen Canal and the Afon Dyfrdwy (River Dee) to its south, and has the town of Llangollen to its south south-east.

 |
| The danger of hill list compilers inventing names for hills and their inappropriate perpetuation is evidenced above, as this is a name I invented many years ago for this hill and it now appears on the National Library of Scotland website |
The land where the summit of this hill is situated is now owned by The Nation Trust and when I first visited this hill I came across a sign at the start of one of the paths leading to its high point which names the hill as Velvet Hill Coed Hyrddyn. This information was forwarded to Geoff Crowther who updated the Welsh 200m P30 list accordingly.

When recently visiting this hill with friends and conducting the Trimble GeoXH 6000 summit survey I met Jonathon Davies, the son of the local farmer and whose family work from the Abbey Farm which is situated below the hill to its north-east. Jonathon’s family have farmed this land since 1934 and he confirmed that the hill is known by both names; Velvet Hill and Coed Hyrddyn, and for the purposes of listing it is the Welsh name that is being prioritised as it has older evidence of use, is known as such locally and also appears on contemporary Ordnance Survey maps and named as such by the present land owner.

Therefore, the name this hill is now listed by in the 200m Twmpau and Y Trechol - The Dominant Hills of Wales is Coed Hyrddyn, and this name was derived from The National Trust, historical and contemporary Ordnance Survey maps and local enquiry.

Mapping Mountains - Significant Name Changes - Y Trechol - The Dominant Hills of Wales
Moel Fynydd (SH 697 161) - 13th significant name change
There has been a Significant Name Change to a hill that appears in the following lists; Y Trichant and Y Trechol – The Dominant Hills of Wales, with the criteria for the two listings that this name change applies to are:
Y Trichant – All Welsh hills at and above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub category entitled the Sub-Trichant consisting of all Welsh hills at and above 300m and below 400m in height that have 20m or more and below 30m of drop. The list is authored by Myrddyn Phillips and the Introduction to the list and the re-naming and publication history was published on Mapping Mountains on the 13th May 2017.
Y Trechol – The Dominant Hills of Wales – All Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height. The list is authored by Myrddyn Phillips with the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3rd December 2015.
The hill is adjoined to the Cadair Idris range of hills which are situated in the south-western part of North Wales (Region A, Sub-Region A3), and it overlooks Llyn Gwernan to its east south-east and the town of Dolgellau to its east north-east.
 |
| Moel Fynydd (SH 697 161) |
The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name of Craig y Castell. During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to and used many names that seemingly applied to a hill and whose placement was nearest the summit of the hill on Ordnance Survey maps of the day. Therefore I prioritised names for listing purposes that I now understand are inappropriate, and as the positioning of the name Craig y Castell on contemporary Ordnance Survey maps implies, that part of the hill is known by this name and is directly associated with an ancient fortification, and in the case of the hill whose summit is positioned at SH 697 161 it was a local farmer who has lived the whole of his life under this hill that gave the name of Moel Fynydd.

The local farmer is Emyr Rees who is aged 70 and is a Welsh speaker and has lived all of his life at Tynyceunant (SH 688 152), this farm is situated to the south-west of the hill. When we met Emyr was wielding a large mallet and was in the process of fixing a post. We met at the start of the access track beside the narrow road that leads to his farm and this hill was directly above us and therefore after introducing myself and explaining my interest in upland place-names, all I had to do was point and say ‘what about that one, has it a name?’, Emyr replied ‘that’s Moel Fynydd’. Emyr also gave me a number of other names for near hills or the bounded land where the summit of each was situated, some have been detailed in previous Significant Name Changes posts, the one that has not will be detailed in a forthcoming one.

Y Trechol - The Dominant Hills of Wales - Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height, with the Introduction to the Mapping Mountains publication of this list appearing on the 3rd December 2015, and the list is now available in its entirety on Mapping Mountains in Google Doc format.
The hill is situated in the Moelwynion range of hills in the Region of North Wales (Region A, Sub-Region A1), and is positioned with the A 4085 road to its north-east and has the Welsh Highland Railway to its immediate west and overlooks the Afon Glaslyn also to its west, and has the village of Beddgelert to its north north-west and the town of Porthmadog to its south south-west.
The hill appeared in the Hills to be surveyed sub list that accompanied the main Welsh P30 lists that were published on Geoff Crowder’s v-g.me website under the name of Coed Hafod-y-llyn. This is the name of the wood where the hill is situated and would be an appropriate name to use if a name for the hill itself did not exist.
| Coed Hafod-y-llyn | 56m | SH598448 | 124 | 18 |
Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, or as in this case whether an individual name for the hill in preference to the name of the wood it is situated in, exists. This is not a practice I now advocate as with time and inclination place-name date can be improved by asking local people or by examining historical documents, through this form of research an appropriate name for the hill can usually be found, and in the case of this hill it was local knowledge from Aled Williams coupled with historical information from the Ordnance Survey series of Six-Inch maps that gave the name of Bryn y Gwynt for this hill.

During my early hill listing I did not lay emphasis on prioritising a name for a hill over that for its summit, and therefore on occasion I used a summit name in preference to that of the hill name, and the use of Beacon Ring is such an example as the hill is known in English as the Long Mountain. This practice can be appropriate if the summit name is prioritised locally, otherwise for listing purposes it is customary to prioritise the hill name in preference to that of its summit.

Also during my early hill listing I thought it sufficient to use English or anglicised names for hills even if a Welsh name existed, this in the main is not a practice that I now advocate, especially if the Welsh name has historical evidence of use, and as the English names for this hill and its summit have Welsh counterparts, these being Cefn Digoll and Caer Digoll respectively, the hill name of Cefn Digoll is being used.
Therefore, the name this hill is now listed by in the Y Pedwarau and Y Trechol – The Dominant Hills of Wales is Cefn Digoll, as this is the Welsh name for the hill.

Mapping Mountains - Significant Name Changes - Y Trechol - The Dominant Hills of Wales
Cefn Nedd (SO 185 965) - 9th significant name change
Survey post for Cefn Nedd
There has been a Significant Name Change to a hill that is listed in the 200m Twmpau and Y Trechol - The Dominant Hills of Wales, with the height, drop, dominance and status of the hill being confirmed by a Trimble GeoXH 6000 survey which took place on the 9th March 2017.
The criteria for the two lists that this name change applies to are:
200m Twmpau - All Welsh hills at and above 200m and below 300m in height that have 30m minimum drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height.
The hill is adjoined to the Beacon Hill range, this group of hills is situated in the north-eastern part of Mid and West Wales (Region B, Sub-Region B1), and the hill is positioned above the B 4385 and the A 483 roads with the Afon Hafren (River Severn) between each, and has the small town of Trefaldwyn (Montgomery) to the east and the village of Aber-miwl (Abermule) to the south-west.

The hill appeared in the 200m P30 list on Geoff Crowder’s v-g.me website under the name Goron-ddu. During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate, and Goron Ddu is such an example as this name has been consistently applied by the Ordnance Survey to land taking in the lower north-westerly slopes of this hill, and not necessarily to the hill itself or its summit, and importantly the placement of this name in relation to the land it is applicable to has also been substantiated by local enquiry, including with the landowner. The former is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historical documents, through this form of research an appropriate name for the hill can usually be found, and in the case of this hill the name of Cefn Nedd was derived from the Tithe map.

| Alan Harding was the second local farmer who substantiated the land that the name of Gorun Ddu is applicable to, and this matches the name placement on the above map, he also put me in contact with the land owner who also substantiated the placement of Gorun Ddu to be on the lower north-westerly slopes of this hill |

| The current Ordnance Survey 1:25,000 Explorer map is not the best for name placement |
The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.
 |
| The enclosed land taking in the summit is given the number 551 on the Tithe map |
The enclosed land where the summit of this hill is situated is given the number 551 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The land where the summit of this hill is situated is named as Cefn Nedd on the Tithe map and described as Cloverley; it appears in the county named as Montgomery and in the parish of Llandysul.
 |
| When cross referenced in the apportionments the enclosed land is named as Cefn Nedd |
Therefore, the name this hill is now listed by in the 200m Twmpau and Y Trechol - The Dominant Hills of Wales is Cefn Nedd, and this was derived from the Tithe map.

There has been a Significant Name Change to a hill that is listed in the Y Pedwarau and Y Trechol - The Dominant Hills of Wales, with the summit height and dominance of the hill being confirmed by a survey with the Trimble GeoXH 6000 which was conducted on the 28th December 2016, with the hill previously analysed via LIDAR data by Aled Williams.
The criteria for the two lists that this name change applies to are:
Y Pedwarau - These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop. The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height. The list is authored by Myrddyn Phillips.
The hill is a part of the Mynydd Epynt range, this group of hills is situated in the south-eastern part of Mid and West Wales (Region B, Sub-Region B-2), and is positioned above the B 4519 road and between the small communities of Garth to its north and Upper Chapel to its south-east.

Hill list authors are prone to list a hill by the name that appears nearest to its summit on Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of Mynydd Eppynt (the name is now presented on Ordnance Survey maps with a single ‘p’ as Mynydd Epynt) the name is more appropriately associated with the hill range rather than an individual hill. However, place-name data can be improved by asking local people and examining historical documents, and in the case of this hill it was a local farmer who gave the name Clepyn Melyn for land near to the summit of the hill, which to the authors knowledge is the main named feature of this hill and therefore appropriate to use for listing purposes.
Therefore, the name this hill is listed by in Y Pedwarau and Y Trechol - The Dominant Hills of Wales is Clepyn Melyn and this was derived from local enquiry.

The hill is a part of the Cilfaesty range, this group of hills is situated in the north-eastern part of Mid and West Wales, and is positioned above the A 489 road and between the town of Trefaldwyn (Montgomery) to its north, Yr Ystog (Churchstoke) to its east, Aber-miwl (Abermule) to its west north-west and Sarn to its south.
The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the transposed name of Caeliber Isaf, which is a name that appeared close to the summit of the hill on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map.
During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing purposes that I now understand are inappropriate, and Caeliber Isaf is such an example as this name has been consistently applied by the Ordnance Survey to land on the southern side of this hill. The name Caeliber Isaf can be translated in to English as the lower fair copse, which is an unusual name if applicable to the highest hill hereabouts, and especially so when one considers that the name Caeliber Uchaf also appears on Ordnance Survey maps and has been consistently applied to land to the west of where the name Caeliber Isaf appears, the translation in to English of Caeliber Uchaf can be given as the upper fair copse. Both names are known locally as applicable to areas or districts of land and not to hills.

Since publication of these P30 lists on Geoff Crowder’s v-g.me website there have been a number of Ordnance Survey maps made available online, some of these are historical such as the series of Six-Inch maps on the National Library of Scotland website, whilst others are current and digitally updated such as the enlarged map hosted on the Geograph website. One of the historical maps now available is the Ordnance Survey One-Inch ‘Old Series’ map, which was the first map made publicly available by the Ordnance Survey and it is this map that has the name of Cefn y Coed running across the summit of this hill and beyond, and when coupled with detail later found on the Tithe map and also through local enquiry it formed the basis of this name being considered the most appropriate for this hill.
The One-Inch ‘Old Series’ was the first map that Ordnance Survey published, and they were based on the preceding Draft Surveyors map. Their publication culminated from the whole of Britain being surveyed between 1791 and 1874 and the detail gathered therein produced at a scale of one inch to the mile and published in sheet format between 1805 and 1874. The One-Inch ‘Old Series’ maps for the whole of Wales are now available online; they are also available in map format as enlarged and re-projected versions to match the scale and dimensions of the Ordnance Survey 1:50,000 Landranger series and are published by Cassini. This series of maps forms another important part in the study of Welsh upland place-names and bridge the time frame leading to the production of the Ordnance Survey base map of the Six-Inch series.

However, many local people now know the name Cefn y Coed to be applicable to an area/district of land and not necessarily to the hill, this was confirmed by Gordon Davies who has lived at Camp Farm all of his life, with his grandfather moving here in 1904, this farm is situated approximately 1.3 km west of the hill’s summit. This hill was surveyed with the Trimble GeoXH 6000 in the company of Rick Salter and Jenny Hatfield and we visited Camp Farm on our descent and I took the opportunity to ask Gordon about the name of the hill.
Gordon knows this hill as Cwm Bromley Top, as the land where the summit of the hill is situated is a part of the farm of Cwm Bromley. This farm is situated to the east of the summit at grid reference SO 226 934. He also knows the point at SO 20930 92921 as Black Hill and explained that this land takes in at least three bounded and fenced fields. Gordon confirmed that Caeliber Isaf is a small district of land which is in the main on the other (southern) side of the hill, and that there are also other areas of land with Caeliber in their names that are also close by.

| Gordon Davies |
Although Gordon knows the hill as Cwm Bromley Top this is only applicable as the land where the summit of the hill is situated, is on land of Cwm Bromley farm. Ideally this needed confirming and therefore I contacted Ted and Merle Davies who have farmed Cwm Bromley since Ted’s family moved there in 1937. Ted is now aged 65 and told me that he knows the field where the high point of the hill is situated as the Tank Field, as there’s a water tank in the field. I asked if he had ever heard, used or referred to the hill or the upper field as Cwm Bromley Top, he had not, although he did say that he’s referred to it as the top of Cwm Bromley, Ted then told me that Cefn y Coed is a little hamlet. As there is no confirmation that Cwm Bromley Top is the name of the hill or the upper field by the farmer from Cwm Bromley farm it may be surmised that this name is not frequently used.
I later checked the Tithe map, the term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.
The enclosed land where the summit of this hill is situated is given the number Q33 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The land where the summit of this hill is situated is named as Cefn y Coed (conforming to standard modern Welsh) on the Tithe map and described as Pasture; it appears in the county named as Montgomery and in the parish of Ceri.

 |
| The land where the summit of this hill is situated is named as Cefn y Coed on the Tithe map |
Although there is now consensus amongst the local community that the name of Cefn y Coed is applicable to a small hamlet or area of land and not necessarily the hill, the Tithe map confirms that the bounded land at the summit of this hill that once took in what is now a number of individual fields was known at the time of the Tithe map as Cefn y Coed, and this is substantiated by the Ordnance Survey One-Inch ‘Old Series’ map. One may presume from this that Cefn y Coed is the name of the land at the summit of this hill, and in all likelihood is the name of the hill itself, and that the passage of time has supplanted this name to also take in the small hamlet and area of land surrounding the hill.

Therefore, the name this hill is now listed by in the Y Trichant - The 300m Hills of Wales and Y Trechol - The Dominant Hills of Wales is Cefn y Coed, and this was derived from the Tithe map and the Ordnance Survey One-Inch ‘Old Series’ map, coupled with information given from local enquiry.

There has been a Significant Name Change to a hill that appears in the following lists; 30-99m Twmpau and Y Trechol - The Dominant Hills of Wales, with the hill's height, drop, dominance and status being confirmed by the survey with the Trimble GeoXH 6000 which took place on the 23rd February 2016, and which confirmed the adjacent easterly summit positioned at SH 56181 37683 as being lower.
The criteria for the two listings that this name change applies to are:
30-99m Twmpau - All Welsh hills at and above 30m and below 100m in height that have 30m minimum drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.
Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height.

| The westerly summit of Moelfre (SH 558 375) |
The hill appeared in the 30m-99m P30 list on Geoff Crowder’s v-g.me website under the name Coed Borth. This name was found through local enquiry with Dewi Jones and at a later date confirmed by Aled Williams; a resident and native of Porthmadog respectively. As Ordnance Survey maps of the day did not give a spot height to the westerly summit, it was the easterly summit with its 72m map spot height that was listed, both have now been Trimbled with the westerly summit proving higher.

During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to. Therefore I prioritised names for listing purposes that I now understand are inappropriate, and Coed Borth is such an example as although this is the locally known name for the wood close to the easterly summit of this hill, it doesn’t take in the actual summit, whilst the same wood has been consistently named as Parc y Borth on Ordnance Survey maps. However, Aled has confirmed that the higher westerly top and its adjacent easterly lower top are locally and collectively known as Moelfre.
Before enquiring with Aled I checked the Tithe map, the term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

 |
| The name where the summit of this hill is situated is named Moelvra on the Tithe map |
The enclosed land where the summit of this hill is situated is given the number 920 on the Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The land where the summit of this hill is situated is named as Moelvra [sic] on the Tithe map and described as Pasture; it appears in the county named as Caernarfon and in the parish of Ynyscynhaearn.
Therefore, the name this hill is now listed by is Moelfre (spelling conforming to standard modern Welsh), and this was derived from local enquiry, as well as the land where the summit of this hill is situated being confirmed by the use of the same name on the Tithe map.

The hill is adjoined to the Mynydd Hiraethog group of hills, which are situated in the northern part of North Wales (Region A, Sub-Region A2), and it is positioned with the A546 road to its west and the B5115 road to its east, and has the town of Deganwy encircling it on three sides.
The hill appeared in the 100m P30 list on GeoffCrowder’s v-g.me website, under the transposed and invented name of Degannwy Castle Top, with an accompanying note stating; Name from remains of castle.
| Degannwy Castle Top | 107m | SH782794 | 115 | 17 | Name from remains of castle. |
During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day. My preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance, use the name of the castle whose remains are situated on the summit of the hill and add the word Top to it. This is not a practice that I now advocate as with research either conducted locally or historically an appropriate name for the hill can usually be found.

| Extract from the Ordnance Survey 1:25,000 Explorer map |
Since publication of these P30 lists on Geoff Crowder’s v-g.me website there have been a number of Ordnance Survey maps made available online, some of these are historical such as the series of Six-Inch maps on the National Library of Scotland website, whilst others are current and digitally updated such as the enlarged map on the Geograph website. One of the historical maps now available is the Ordnance Survey Draft Surveyors map which formed the basis for the first publicly available Ordnance Survey One-Inch ‘Old Series’ map, and it is the Draft Surveyors map coupled with local enquiry and detail on Ordnance Survey 1:25,000 Explorer maps that formed the basis for the change in this hill’s listed name.
 |
| Extract from the Ordnance Survey Draft Surveyors map |
The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey’s surveyors between the 1780s and 1840 and formed the basis for the first publicly available One-Inch map. They were drawn at scales of six inches to the mile for areas considered of particular military significance and down to two inches to the mile for other areas. Fair copies were then produced from these preliminary drawings to one inch to the mile and then copper plates were prepared for printing. The Draft Surveyors maps for the whole of Wales are now available online and they form an important part in the study of Welsh upland place-names as they bridge the time frame between the late 18th century and the mid-19th century when the Ordnance Survey produced their first One-Inch maps.
The summit of this hill has the remains of Castell Deganwy (Degannwy Castle in English) situated on it, and local enquiry as well as research online coupled with detail on Ordnance Survey maps indicates that the hill is also known as The Vardre, this is an obvious anglicisation of a Welsh word, and it is the Draft Surveyors map that gives historical documentation of its original form; Y Faerdre, the meaning of this word is an area of land where crops were grown under the supervision of the steward. It is appropriate to use the name Y Faerdre as opposed to that of the anglicised form as the Welsh form is prioritised when list compiling.
Therefore, the name this hill is now listed by in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales is Y Faerdre and this was derived from a number of sources with the original Welsh form being used on the Ordnance Survey Draft Surveyors map, and the anglicised form from local enquiry and the contemporary Ordnance Survey 1:25,000 Explorer map.

The criteria for the two listings that this name change applies to are:
100m Twmpau - Welsh hills at or above 100m and below 200m in height that have 30m minimum drop, with an accompanying sub list entitled the 100m Sub-Twmpau, with the criteria for this sub category being all Welsh hills at or above 100m and below 200m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

Y Trechol – The Dominant Hills of Wales – Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height. The list is authored by Myrddyn Phillips with the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3rd December 2015, and the list is now available in its entirety on Mapping Mountains in Google Doc format.

| Y Trechol - The Dominant Hills of Wales by Myrddyn Phillips |
The hill is adjoined to the Mynydd Hiraethog group of hills, which are situated in the northern part of North Wales (Region A, Sub-Region A2), and it is positioned with the B5115 road to its north, the A470 road to its west and minor roads to its south and east, and has the town of Llandudno towards the north-west.
The hill appeared in the original Welsh 100m P30 list on Geoff Crowder’s v-g.me website, under the invented and transposed name of Pen Goed Gaer, with an accompanying note stating; Name from wood at summit.
| Pen Coed Gaer | 130c | SH802810 | 115/116 | 17 | Name from wood at summit. |
During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day. My preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance transpose the name of a wood and add the word Pen to it. This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found. However, as an appropriate name for this hill already exists on the contemporary Ordnance Survey 1:25,000 Explorer map, the use of the invented and prefixed word of Pen is unnecessary.

Therefore, the name this hill is now listed by in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales is Coed Gaer, and this was derived from a variety of Ordnance Survey maps including the contemporary 1:25,000 Explorer map.

The hill is adjoined to the Mynydd Hiraethog group of hills, which are situated in the northern part of North Wales (Region A, Sub-Region A2), and it is positioned with the B5115 road to its south-west, and has the town of Llandudno towards the west.
The hill appeared in the original Welsh 100m P30 list on Geoff Crowder’s v-g.me website, under the transposed name of Creigiau Rhiwledyn, which is a prominent name that appears close to its summit on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map, with an accompanying note stating; aka Little Orme or Little Ormes Head.
| Creigiau Rhiwledyn | 141m | SH813824 | 116 | 17 | aka Little Orme or Little Ormes Head. Trig pillar. |
During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to. Therefore, I prioritised names for listing purposes that I now understand are inappropriate, and Creigiau Rhiwledyn is such an example as this name has been consistently applied by the Ordnance Survey to the cliffs that are positioned north-eastward of the summit of this hill, and although it can be appropriate to use the main named feature of a hill for listing purposes, in this instance the hill has its own Welsh name, and this is Trwyn y Fuwch.

The intricacies of language and prioritising one in favour of another for listing a hill is fraught with complication, with originating Cymraeg names being anglicised and also originating English names being cymricised, examples such as these are more common in border country and especially so for anglicised forms. There is no steadfast rule that fits all, but as a standard a name that has its origins in the Welsh language and where this is substantiated by either historic documentation and/or contemporary usage should be prioritised in favour of a contemporary anglicised or English version of the name. Likewise, if a name exists where an element of it is in English and if this name applies to a hill that is situated in a Welsh speaking part of Wales it is standard practice to use a full Welsh term for the name. It is also standard practice to use a Welsh name for a hill if another name exists that has originated in a different language.
Therefore, the name this hill is now listed by in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales is Trwyn y Fuwch, and this was derived from a variety of sources including the Dictionary of the Place-Names of Wales (Hywel Wyn Owen and Richard Morgan, Gomer Press 2007), with the prioritised language protocol being used.

Craig Berwyn (SJ 071 323) - 2nd significant name change
Summit survey post for Craig Berwyn
Bwlch survey post for Craig Berwyn
There has been a Significant Name Change to a hill that appears in the following lists; Y Pellennig, Yr Uchafion, 800m Twmpau and Y Trechol - The Dominant Hills of Wales, with the following details relating to a hill whose summit was surveyed with the Trimble GeoXH 6000 on the 21st June 2014 and its bwlch on the 13th September 2019.
The criteria for the four listings that this name change affects are:
Y Pellennig –The Remotest Hills of Wales comprise all Welsh hills whose summit is 2.5km or more from the nearest paved public road and which have a minimum 15m of drop. The list is co-authored by Myrddyn Phillips and Aled Williams.
Yr Uchafion - All Welsh hills at or above 500m in height that have 15m minimum drop. The list is co-authored by Myrddyn Phillips and Aled Williams.
800m Twmpau - All Welsh hills at or above 800m and below 900m in height with 30m minimum drop. The list is authored by Myrddyn Phillips.
Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height.
The hill is situated in the Y Berwyn, which is an extensive group of hills positioned in the south-eastern part of north Wales, and is relatively remote for a Welsh hill with the nearest towns being Llandrillo to the north-west and Llanarmon Dyffryn Ceiriog to the east.

The hill first made an appearance in a hill list as Cader Berwyn, S. Top in a 1929 update to the Twenty-Fives which was compiled by John Rooke Corbett and published by the Rucksack Club Journal. Since this time the hill has been listed a number of times and usually by names associated with that of Cadair Berwyn, which strictly speaking is the hill to its north positioned at SJ 072 327, and which has a triangulation pillar situated at its summit and a map height of 827m.
Unfortunately all previous hill list authors have used the map name that appears nearest to the summit of this hill, although doing this is convenient it has conjured up all manner of combinations of inappropriate names centred around that of its adjacent hill, these names include; Cadair Berwyn New Top, Cadair Berwyn South Top as well as the use of the adjacent hill’s name; Cadair Berwyn.
The hill was only confirmed by the Ordnance Survey as the highest in the Y Berwyn when contacted by Bernard Wright who had recognised that the summit of the hill was higher than its adjacent northerly peak; Cadair Berwyn, and also higher than its adjacent southerly peak; Moel Sych, Bernard suggested the name of Craig Uchaf for this hill as it seemingly had no name for it on the map of the day. This is the name previously given the hill in unpublished format within the Yr Uchafion prior to extensive place-name research for this area taking place.
As a result of this research the hill has subsequently appeared under the name of Craig Berwyn in all four of the previously mentioned lists, this is the name that some local farmers and shepherds know the hill by, ironically this name already appears on Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps.

There has been a Significant Name Change to a hill that is listed in the Y Trichant and Y Trechol - The Dominant Hills of Wales, with the following details relating to a hill that was surveyed with the Trimble GeoXH 6000 on the 7th February 2014 and also on the 2nd May 2014 along with the Leica GS15.
The criteria for the two listings that this name change affects are:
Y Trichant - These are the Welsh hills at and above 300m and below 400m in height that have 30m minimum drop, with the introduction to the re-naming and the publication history of this list appearing on Mapping Mountains on the 13th May 2017.
Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height. With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height.
The hill is situated in the Pumlumon range, which is an extensive group of hills in the northern part of mid Wales. The hill is positioned to the south-west of Caersws and to the north-east of Llanidloes, with the small community of Llandinam and the Afon Hafren (River Severn) to its east.

The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name of; Rhosfawr, which at that time was taken as the name of the hill, however this is the name of a farm which is situated to the west of the hill’s summit.

The name this hill is now listed by is Gelli Hir, this name can be translated as long grove, and this was derived from examination of the Ordnance Survey Historical 1:25,000 map as well as the Tithe map, coupled with tentative details from local enquiries. The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act. This act allowed tithes to be paid in cash rather than goods. The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land. This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.
 |
| The Ordnance Survey Historical 1:25,000 map is probably the best OS map for placement of names relating to hills and their features, on this map Gelli Hir appears close to the summit of this hill and following its upper northerly ridge |
When I first surveyed this hill I made place-name enquiries with a local resident to the south south-east of the hill. The details are given below:
After visiting the summit of Y Gaer at SO 013 873, I descended to the farm of Cefn and surprised Graham Pugh who was heading to the farm yard from a large barn full of recently born lambs. Graham is aged 53 and had lived in the local area for 25 years and at the farm of Cefn for 20 years, he originally comes from Staylittle / Penffordd-las (SN 887 920). He can speak Welsh but said that he gets his ‘rights’ and ‘lefts’ muddled up and told me about a visit to a market where he was given directions and he couldn’t remember if the word meant left or right, we both chuckled at this. I believe this was due to a lack of Welsh being spoken in the area where Graham now lives, so his use of the language is not on a daily basis. I explained where I had come from and where I was heading. We were soon talking about the name of the hill.
Graham told me he didn’t really know a name for this hill, I asked if he ever referred to the hill by any name and he said that he just calls it Top of the Bwlch. The farm of Bwlch is situated at SN 995 875, it seems the summit of the hill is on their land. I asked if he had ever heard the name of Gelli Hir in relation to this hill. He then said that this was funny as he’d had a recent conversation with the person from Coedmawr farm, who had just bought the land going up to the top of this hill from the other (north-west) side and they had called it Gelli something. The name of Gelli Hir (Gelli-hir on older maps) appears on current maps just below the summit of this hill. However, on older OS maps this name appears as a ‘ridge’ name going across the top of the hill and down its northern ridge.

Place-name research can be similar to fitting pieces of a giant jigsaw together, each piece is important, but on occasion the pieces (the information given) seem as if they do not fit together. However, each piece of information is important and can be assessed against other information found at a later date. And this was so with this hill’s name, as I already knew that the Historical 1:25,000 map has the name of Gelli Hir following the upper northern ridge of this hill, as this map is by far the most precise produced by the Ordnance Survey for place-name position I was inclined to believe that the name of Gelli Hir was appropriate to use for this hill, and the information given by Graham Pugh, although only tentative, was also substantive when coupled with the placement of this name on the old 1:25,000 map. I hoped that the Tithe map would substantiate the use of Gelli Hir for this hill’s name.
Unfortunately the Tithe map for this area is almost unintelligible, however the number 2096 is given to the adjoining land to where the summit of this hill is situated, this number can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land. The land given the number of 2096 is named as Allotment on the Tithe map, and importantly the next number; 2097, which is probably the adjoined land, is named as Gelli hir and is described as Pasture; these details are listed under the county named as Montgomery and in the parish of Llandinam.

| Accessing information on the Tithe map is simplified by the use of a split screen enabling the summit to be pinpointed on the map on the right and for the same point to appear on the Tithe map on the left. Unfortunately in this instance the Tithe map is almost unintelligible, however the number 2096 is given to the adjoined land |
