Castell Meherin (SN 146 117)
There has been a Significant Name Change to a hill
that is listed in the 200m Twmpau, with
the summit height and drop of the hill being confirmed by LIDAR analysis, with a subsequent Trimble GeoXH 6000 summit survey, with both conducted by Myrddyn Phillips.
Using the LIDAR technique has substantiated that
the natural bwlch of this hill is still, just, intact, as a minor road passes
over this point, with the following results produced through LIDAR analysis:
162.482m bwlch on minor road at SN 18485 12815
162.237m natural bwlch at SN 18517 12805
These positions are aligned on the hill to hill
traverse and even though the bwlch on the minor road is higher, it is the
natural bwlch position and its height that forms the quoted drop value of this
hill, as this exists it is prioritised over any man-made construct.

The criteria for the list that this name change
applies to are:
200m Twmpau – Welsh hills at or above 200m and below 300m in
height that have 30m minimum drop, with an accompanying sub category entitled
the 200m Sub-Twmpau consisting of all
Welsh hills at or above 200m and below 300m in height that have 20m or more and
below 30m of drop. With the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.
The hill is adjoined to the
Brandy Hill group of hills, which are situated in
the south-western part of Mid and West Wales (Region B, Sub-Region B4), and is
positioned with the B 4328 road to its north and has the town of Arberth (Narberth)
towards the north-west.

The hill appeared in the 200m P30 list on Geoff
Crowder’s v-g.me website under the invented name of Middleton Hill, with an accompanying note stating; Name from farm 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 when the
farm had an English name use the word Top
or Hill after 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.
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.
The enclosed land where the summit of this hill is
situated is given the number 36 on the Tithe map, with enclosed land close to
it given the number 33, 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 land where the summit of this hill is
situated has part of same given to it
and this refers to the near field given the number of 33, and this is given the
name of Part of Castle Merrin on the
Tithe map, the
details of which appear in the county named as
Pembrokeshire and in the parish of Ludchurch.

With any upland place-name it is advantageous to
substantiate it from a second source, and in the case of this hill this can initially
be done through contemporary and historical Ordnance Survey maps, as the Tithe map
implies that the land where the summit of this hill is situated is either known
as Castle Merrin or it is adjoined to a farm known by the same name.
Therefore, contemporary Ordnance Survey maps were
examined and there is a farm given the name of Castle Mehren on the 1:25,000
Explorer map which is positioned north north-east of the summit of this hill at
SN 148 120, and as there are a series of ancient earthworks that take in the
land comprising the upper part of this hill, in all likelihood the farm took
its name from that of the earthworks.

However, although the Tithe map gives a name for
the enclosed land at the summit of this hill, and the contemporary Ordnance
Survey 1:25,000 Explorer map substantiates the use of a farm name in relation
to the Tithe information, it is historical Ordnance Survey maps that give the
name of these ancient earthworks.
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. Two of the historical maps now available are the
Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance
Survey One-Inch ‘Old Series’ map, and both maps give the name of Castle Merrin
in relation to this hill.
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 timeframe
between the late 18th century and the mid-19th century
when the Ordnance Survey produced their first One-Inch maps.

The One-Inch ‘Old
Series’ map was the first map that the Ordnance Survey produced, and 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 form another important
part in the study of Welsh upland place-names and bridge the timeframe leading
up to the production of the Ordnance Survey base map of the Six-Inch series.

The use of the name
Castle Merrin, which is now presented by the farm name of Castle Mehren on
contemporary Ordnance Survey maps is an anglicisation of the originator word which
is Welsh. Research online quickly found
what name is the originator for these anglicised versions, this name is Castell
Meherin, and this is substantiated from historical records as given below in an
extract from the Royal Commission on the Ancient and Historical Monuments in Wales
and Monmouthshire:

The name of Castell
Meherin is also substantiated by present day documentation, some of which is
given by Coflein, which is the online database for the National Monuments Record
of Wales and also by a number of other online sites, including Cadw, which is
the historic environment service of the Welsh Government and part of the
Tourism and Culture group.
As the ancient earthworks
comprise two distinct elements these are sometimes referred to as Castell
Meherin West and Castell Meherin East, with the name also documented as Castell
Meherin Camps, but all are derivatives of their originator; this being Castell Meherin.
Therefore, the name this
hill is now listed by in the 200m Twmpau is Castell Meherin and this
was derived from historic and contemporary documentation.
