Mapping Mountains – Significant Name Changes – Y Pedwarau

Mynydd Tŷ Cerrig (SJ 147 405)

This is the thirty sixth 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 18th September 2015.

The hill is situated in Y Berwyn, which is an extensive range of hills in the south-eastern part of north Wales.  The hill is positioned between the small communities of Glyndyfrdwy to the north, Llangollen to the east north-east and Glyn Ceiriog to the east south-east.

The hill appeared in the 400m P30 list on Geoff Crowder’s website under the invented name of Pen Ty’n-y-graig, with an accompanying note stating; Name from wood to the North-East, with Ty’n-y-graig  being the name of a farm and its adjacent wood; Coed Ty’n-y-graig.  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. 

Pen Ty'n-y-graig
   Name from wood to the North-East

During my early hill listing I thought it appropriate to invent a name for a hill if no name seemed to appear for it on Ordnance Survey maps of the day.  My preference was to use farm names and put Pen, Bryn or Moel in front of them.  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 and it was local enquiry that gave the name of Mynydd Tŷ Cerrig for this hill.

The name this hill is now listed by in Y Pedwarau (Europeaklist May 2013 and Haroldstreet January 2014) is Mynydd Tŷ Cerrig (conforming to standard modern Welsh), and this was derived from local enquiry.
