Bonc yr Hafod (SJ 311 469)
This is the forty first 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 20th October 2015.
The hill is part of the group of hills associated with Moel y Gamelin, this range of hills are situated in the north-eastern part of north Wales. The hill overlooks the A 483 and is positioned on the north-eastern outskirts of Johnstown and Rhosllanerchrugog.

The hill appeared in the 100m P30 list on Geoff Crowder’s v-g.me website under an invented name of Bryn-y-hafod, with an accompanying note stating; Name from house to the South, with Hafod House being a large residence to the south of the hill. The listing this hill is now a part of is named Twmpau (thirty welsh metre prominences and upward) and its height was confirmed by the survey with the Trimble.
Name from house to the South
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 and in this instance I prefixed the name of a large house with that of Bryn. 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 in this instance the name the hill is now listed by comes from the updated details on current Ordnance Survey 1:25,000 Explorer maps.
