Mapping Mountains – Significant Name Changes – Y Pedwarau

Coedcae Colfrân (SN 936 330)

This is the twenty fifth post under the heading of Significant Name Changes, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 10th June 2015.

The hill is part of Mynydd Epynt, which is an extensive group of hills situated in the south-easterly part of mid and west Wales.  The hill is positioned between the small communities of Pentre-bach to the west and Llanfihangel Nant Brân to the north-east, with the town of Pontsenni (Sennybridge) towards the south.

The hill appeared in the 400m P30 list on Geoff Crowder’s website under the invented name Pen Maesmerddyn, with an accompanying note stating; Name from fields to the North-West.  This listing of hills is now co-authored with Aled Williams and known as Y Pedwarau, and the hill’s status as a Pedwar was confirmed by the survey with the Trimble.

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 what I presumed to be a field.  This is not a practice that I now advocate as with a little research either conducted locally or historically an appropriate name for the hill can usually be found.

Since publication of these P30 lists on Geoff Crowder’s 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 One-Inch ‘Old Series’ map which was the first map made publicly available by the Ordnance Survey.

An extract from the Ordnance Survey One-Inch 'Old Series' map naming the hill as Coedcae Colfrân

The name this hill is now listed by in Y Pedwarau (Europeaklist and Haroldstreet 2013) is Coedcae Colfrân, and this was derived from the Ordnance Survey One-Inch ‘Old Series’ map.
