30-99m
Twmpau – Significant Name Changes
The 30-99m Twmpau (thirty welsh metre prominences and upward) are the Welsh hills at or above 30m and
below 100m in height that have a minimum drop of 30m. Accompanying the main P30 list is a sub list
entitled the 30-99m Sub-Twmpau with
the qualification to this sub category being all Welsh hills at or above 30m
and below 100m in height with 20m or more and below 30m of drop.
The list is authored by Myrddyn
Phillips and the posts that have appeared on Mapping Mountains detailing the
significant name changes to the main P30 list and the sub list appear below
presented chronologically in receding order.
Mapping Mountains - Significant Name Changes - 30-99m Twmpau
Coed Rhedyn (ST 363 893) - 35th significant name change
Coed Rhedyn (ST 363 893) - 35th significant name change
There has been a Significant Name Change to a hill that is listed in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height and their locations, the drop, dominance 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:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m 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 which is now available in its entirety on Mapping Mountains in Google Doc format.
The hill is adjoined to the Gwent Is Coed group of hills which are situated in the south-eastern part of South Wales (Region C, Sub-Region C3), and it is positioned with the A48 road to its west and the M4 motorway to its north, and has the city of Casnewydd (Newport) towards the west south-west.
The hill appeared in the original 30-99m Welsh P30 list on Geoff Crowder’s v-g.me website under a partly transposed and invented name of Pen Coed Rhedyn, with an accompanying note stating; Name from wood to the West.
| Pen Coed Rhedyn | 81m | ST364893 | 171 | 152 | Name from wood to the 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 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.

As the summit position indicated by LIDAR is to woodland that comprises a part of Coed Rhedyn and as this is the main named feature of this hill, this name is appropriate to use for the hill and therefore adding an invented name to it is unnecessary.
Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Coed Rhedyn, and this was derived from the contemporary Ordnance Survey 1:25,000 Explorer map.
The full details for the hill are:

Cae Rosser (SO 388 005) - 34th significant name change
There has been a Significant Name Change to a hill that is listed in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height and their locations, the drop, dominance and status of the hill confirmed by LIDAR analysis conducted by Myrddyn Phillips.

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 which is now available in its entirety on Mapping Mountains in Google Doc format.
The hill is adjoined to the Gwent Is Coed group of hills which are situated in the south-eastern part of South Wales (Region C, Sub-Region C3), and it is positioned with the A472 road to its north and the A449 road to its east and the Afon Wysg (River Usk) to the west, and has the town of Brynbuga (Usk) towards the north north-west.
The hill originally appeared in the 30-99m P30 list on Geoff Crowder’s v-g.me website under the transposed name of Red Hill, which is a name adjoined to a minor road on the contemporary Ordnance Survey 1:25,000 Explorer map and not necessarily to the hill itself.
| Red Hill | 70c | SO388005 | 171 | 152 |
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.

As this hill comprises bounded land 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.

| Extract from the Tithe map |
The enclosed land where the summit of this hill is situated is given the number 317 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 Rosser in the apportionments, with the details on the Tithe map appearing in the parish of Llangeview [sic] and in the county named as Monmouth.

The hill is adjoined to the Bro Morgannwg group of hills, which are situated in the southern part of South Wales (Region C, Sub-Region C2), and as its name implies; it is an island that is situated in the Bristol Channel at the mouth of the River Severn, and has the city of Caerdydd (Cardiff) towards the north and the town of Weston-super-Mare towards the east south-east.
The hill appeared in the original 30-99m Welsh P30 list on Geoff Crowder’s v-g.me website under the name of Flat Holm, which is the name that appears for the island on contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps.

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 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Ynys Echni, as the Welsh name for this hill is prioritised over the anglicised version of its originating Old Norse counterpart of Flat Holm (ON floti, holmr), which for listing purposes is standard practice.

The hill is adjoined to the Bro Morgannwg group of hills, which are situated in the southern part of South Wales (Region C, Sub-Region C2), and it is positioned with the A4160 road to its south-west and the Bristol Channel to its east, and with the summit of the hill being a part of the town that takes its name from the hill; Penarth, which is situated to the south of the city of Caerdydd (Cardiff).
The hill appeared in the original 30-99m Welsh P30 list on Geoff Crowder’s v-g.me website under a partly transposed and invented name of Penarth Head Hill, with an accompanying note stating; Name from headland to the East.

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 headland and add the word Hill 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.

The land this hill incorporates takes in the headland that encloses the hill to its east; this is named Penarth Head on contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps. The summit of this hill is now a part of an urban development and town, which is named Penarth; with the town taking its name from the hill. The translation of Penarth can mean head of the promontory; therefore Penarth Head is tautological, albeit with the repetition in a different language.
Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Penarth, and this was derived from contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps and deduction of the names meaning.

Mapping Mountains - Significant Name Changes - 30-99m Twmpau
Hopkins Mount (ST 170 678 & ST 170 679) - 28th significant name change
There has been a Significant Name Change to a hill that is listed in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height and their locations, the drop, dominance 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:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m 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, with the Introduction to the Mapping Mountains publication of this list appearing on the 3rd December 2015 and available in Google Doc format.
The hill is adjoined to the Bro Morgannwg group of hills, which are situated in the southern part of South Wales (Region C, Sub-Region C2), and it is positioned with the B4267 road to its north-west and has a minor road to its south and east, and has the village of Sili (Sully) towards the west.
When the original 30-99m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was listed under the partly invented and transposed name of Swanbridge Hill, with an accompanying note stating; Name from hamlet 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 transpose the name of a near hamlet and add the word Hill 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.

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 historic 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 Vector Map Local hosted on the Geograph website and which is entitled the Interactive Coverage Map, and it is the Ordnance Survey Vector Map Local and the series of Six-Inch maps that name the area taking in the summit of this hill as Hopkins Mount.

There has been a Significant Name Change to a hill that is now listed in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height and their locations, the drop, dominance and status of the hill confirmed by LIDAR analysis conducted by Myrddyn Phillips.
 |
| LIDAR image of Ash Tip (ST 031 663) |
The criteria for the two listings that this name change applies to are:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m 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, with the Introduction to the Mapping Mountains publication of this list appearing on the 3rd December 2015.
The hill is adjoined to the Bro Morgannwg group of hills, which are situated in the southern part of South Wales (Region C, Sub-Region C2), and it forms a part of landscaped ground that once made up the Aberthaw quarry and lime works, and it is positioned with the B4265 road to its north, and has the small community of Sain Tathan (St Athan) towards the north-west.
When the original 30-99m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was not included in either the main P30 list or the Hills to be surveyed sub list, as contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps of the day showed the area that now makes up this hill as having no ring contours of note.
 |
| Extract from the Ordnance Survey 1:25,000 Explorer map |
This area was re-examined when the OS Maps website became available online. This is the replacement for OS Get-a-map and has contours at 5m intervals and for the majority of land comprising old mine workings it shows present day contours, as opposed to the blank space showed on the counterparts of the 1:50,000 Landranger and 1:25,000 Explorer maps.
 |
| Extract from the OS Maps website |
However, it was not until LIDAR became available that the details for this hill could be accurately re-assessed. The LIDAR (Light Detection & Ranging) technique produced highly accurate height data that is now freely available for much of England and Wales.
With contouring on the OS Maps website indicating this hill to now have over 30m of drop and with this confirmed by LIDAR analysis I made local enquiries and contacted Richard Coleman who runs the Blue Anchor Inn; the local pub in East Aberthaw. Richard is aged 31 and told me that his family have run this pub since 1941 and the hill I was interested in is known locally as the Ash Tip.
Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Ash Tip, and this was derived from local enquiry.
The full details for the hill are:

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 Bro Morgannwg group of hills, which are situated in the southern part of South Wales (Region C, Sub-Region C2), and it is positioned with the A4222 and A48 roads to its north with minor roads to its west, south and east, and has the town of Y Bont-faen (Cowbridge) to the north-west.
The hill originally appeared in the Welsh 30-99m P30 list on Geoff Crowder’s v-g.me website under the partly invented and transposed name of Long Grove Hill, with an accompanying note stating; Name from wood to the North-East.

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 199 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 Deg Erw Llandafin in the apportionments, with the details on the Tithe map appearing in the parish of Saint Hilary and in the county named as Glamorganshire.
 |
| Extract from the apportionments |
Therefore, the name this hill is now listed by in the 30-99m Twmpau and what it would be listed by in the Y Trechol – The Dominant Hills of Wales if it had remained a Lesser Dominant hill is Deg Erw Llandafin, and this name was derived from the Tithe map.

The land this hill incorporates takes in the headland that encloses the hill on its west and south, and as this headland is named Trwyn y Witch on contemporary Ordnance Survey map, for listing purposes this is an appropriate name to use for that of the hill, therefore there is no need to add the word Pen to it.

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.
The hill is adjoined to the Ynys Môn group of hills, which are situated in the north-western part of North Wales (Region A, Sub-Region A1), and it has the A5 and A55 roads to its south, and has the village of Gwalchmai towards its south.
This hill was first listed in the original Welsh 30-99m P30 list published on Geoff Crowder’s v-g.me website, under the transposed name of Bryn-teg, which is a name appearing near to the hill on contemporary Ordnance Survey maps and which I presumed was the name of the hill, it is not, it is a name of a house.

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 a name on the map which I presumed to be that of the hill. 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.

After visiting this hill I called at a number of houses, including Bryn-teg hoping to make place-name enquiries. I was directed down the minor lane toward a cottage, as I headed toward the cottage a man appeared and walked toward a plot of land where his daughter was planning to live. Gwyn Thomas lived at one of the houses I’d passed on the lane; the hill was on the other side of the road to where his daughter was planning to live and was at the back of Gwyn’s house. I introduced myself and explained my interest in hill names and asked if he knew a name for the hill; he replied immediately and told me its name is Mynydd Bach.

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

Mapping Mountains - Significant Name Changes - 30-99m Twmpau
Pryslan (SS 719 939) - 20th significant name change
There has been a Significant Name Change to a hill that is listed in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales, with the summit height, its location and the drop of the hill confirmed by LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the two listings that this name change applies to are:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m 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 B4290 road to its west, the A483 road and Bae Baglan (Baglan Bay) to its south, and has the town of Castell-nedd (Neath) towards the north-east.
The hill originally appeared in the 30-99m P30 list on Geoff Crowder’s v-g.me website under the partly invented and transposed name of Bryn y Crymlyn, with an accompanying note stating; Name from burrows to the South.

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 burrows and prefix it with the words Bryn y. 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 396 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 Prislan & Wood in the apportionments, with the details on the Tithe map appearing in the parish of Cadoxton juxta Neath and in the county named as Glamorgan.
 |
| Extract from the apportionments |
Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Pryslan, and this name was derived from the Tithe map.

Group: Fforest Fawr

The hill is adjoined to the Ynys Môn group of hills, which are situated in the north-western part of North Wales (Region A, Sub-Region A1), and as its name implies it is an island that is adjoined to a larger island by an aluminium bridge, and is positioned to the west of the north-western part of Ynys Gybi (Holy Island).
This hill was first listed in the original Welsh 30-99m P30 list published on Geoff Crowder’s v-g.me website under the name of South Stack, with an accompanying note stating; AKA Ynys Lawd, with both of these names appearing on Ordnance Survey 1:25,000 Explorer maps of the day.

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.

Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Ynys Lawd, and this was derived as the Welsh name for this hill is prioritised over its English counterpart, which for listing purposes is standard practice.

The hill is adjoined to the Ynys Môn group of hills, which are situated in the north-western part of North Wales (Region A, Sub-Region A1), and it has the A5025 road to its west and the coast to its north and east, and overlooks Traeth-coch (Red Wharf Bay) to its south-east, and has the village of Benllech towards its north-west.
This hill was first listed in the original Welsh 30-99m P30 list published on Geoff Crowder’s v-g.me website, under the partly transposed and invented name of Moel Castell Mawr, with an accompanying note stating; Name from remains of castle to the South-East.

After visiting this hill I called at the Plas Gwyn Caravan and Camping Park which is situated just below the hill to the south and met David Bennet who explained that the land taking in this hill is owned by Michael Buckley, David kindly directed me to Michael’s home, which I called out twice over the following few days without any reply. However, on my first visit I met Mark Griffith who was trimming a hedge and he kindly gave me a contact telephone number for Michael. When I contacted Michael he explained that the hill has been owned by his family for many years and that it is known after that of the farm, Plas Gwyn.
Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Plas Gwyn, and this was derived from local enquiry.

When this hill was subsequently listed in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales it appeared under the name of Bodlondeb Wood, which is a name that appears on the contemporary Ordnance Survey 1:25,000 Explorer map.

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.
Therefore, the name this hill is now listed by in the 30-99m Twmpau and Y Trechol – The Dominant Hills of Wales is Coed Bodlondeb, and this was derived as the Welsh name for this hill is prioritised over its English equivalent, which for listing purposes is standard practice.
The full details for the hill are:

The criteria for the two listings that this name change applies to are:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m 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, with the Introduction to the Mapping Mountains publication of this list appearing on the 3rd December 2015.
The hill is adjoined to the Pen Llŷn group of hills, which are situated in the western part of North Wales (Region A, Sub-Region A1), and it has the A497 road to its immediate south-east and the B4417 road to its north-west, and has the small town of Nefyn to the north.
This hill was first listed in the Hills to be surveyed sub-list that accompanied the original Welsh 30-99m P30 list published on Geoff Crowder’s v-g.me website, under the invented name of Fron Oleu, with an accompanying note stating; Name from buildings 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 transpose the name of buildings that are situated near the summit of this hill. 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.

The hill is adjoined to the Pen Llŷn group of hills, which are situated in the western part of North Wales (Region A, Sub-Region A1), and the hill is encircled by minor roads with the coast to its south-west and east, and has the village of Abersoch towards its north-east.
This hill was first listed in the Hills to be surveyed sub-list that accompanied the original Welsh 30-99m P30 list published on Geoff Crowder’s v-g.me website, under the invented name of Bryn Llanengan, with an accompanying note stating; Name from village to the North-West.

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.

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.

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. 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 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 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 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.

The criteria for the two listings that this name change applies to are:
30-99m Twmpau - Welsh hills at or above 30m and below 100m in height with 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m 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 addition Welsh P30 hills whose prominence is 33.33% or more and below 50% of their absolute height, with the Introduction to 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 Afon Llwchwr (River Loughor), the B 4297, the A 48 and the M 4 all to the west, and has the town of Pontarddulais towards the south south-east.
The hill originally appeared in the 30-99m P30 list on Geoff Crowder’s v-g.me website under the name of Tal y Fan with an accompanying note stating; Name from buildings 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 transpose the farm name for that of the hill. 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.

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 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.
