Mapping Mountains – Significant Name Changes – 30-99m Twmpau

Rhos Trebared (SN 173 475) 

There has been a Significant Name Change to a hill that is listed in the 30-99m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the list that this name change applies to are:

30-99m Twmpau - Welsh hills at or above 30m and below 100m in height that have 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.

The hill is adjoined to the Mynydd Bach group of hills, which are situated in the western part of South Wales (Region B, Sub-Region B1), and it is positioned with the coast to its north-west, the B4548 road to its north-east and a minor road to its south, and has the town of Aberteifi (Cardigan) towards the south.

The hill appeared in the original Welsh 30-99m P30 list on Geoff Crowder’s v-g.me website, under the transposed name of Trebared, with an accompanying note stating; Name from buildings to the South-East.

Name from buildings to the South-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 farm and use it 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.

When compiling the list of the Y Trechol – The Dominant Hills of Wales I made place-name enquiries for a number of hills, including this one.  Subsequent LIDAR analysis has deleted this hill from Lesser Dominant status as its drop is insufficient for qualification.  However, the local enquiry made relating to the name of this hill is also used in the 30-99m Twmpau list.

I contacted Glen Johnson in relation to this hill and its name.  Glen had conducted a tremendous amount of research concentrating on the area surrounding Aberteifi (Cardigan).  He explained that the name Trebared is associated with a family named Bareth who lived in Aberteifi.  He had accessed records placing this family in this area as far back as the 1200’s.  Their name was recorded in 1302 as Bareth, this later mutated to Barret, which under soft mutation became Bared, and this latter name lends itself to the farm named Trebared, and this farm is now named Rhos Fach.  We then discussed the name of Rhos Trebared and Glen explained that although there is farmland to the south of the present day Rhos Fach, the name of Rhos Trebared would be taken from land above and up to the farm of Trebared.  Therefore, this land would at one time, be known as Rhos Trebared.

Therefore, the name this hill is now listed by in the 30-99m Twmpau is Rhos Trebared and this was derived from local enquiry.
