Crasty Frain (SO 109 983)
There has been a Significant Name Change to a hill
that is listed in the 200m Twmpau, with
the summit height, bwlch height and their locations, the drop and status of the
hill initially confirmed by Joe Nuttall who produced a summit analysis programme using LIDAR, and then by LIDAR analysis conducted initially by Jim
Bloomer and subsequently by Myrddyn Phillips, with the summit later surveyed
with the Trimble GeoXH 6000 and which was conducted by Myrddyn Phillips.

| Crasty Frain (SO 109 983) |
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 with 30m
minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with
the criteria for this sub category being all Welsh hills at or above 200m and
below 300m 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 Carnedd
Wen group of hills which are situated
in the south-eastern part of North Wales (Region A, Sub-Region A4), and it is
positioned with a minor road to its north and the B4389 road to its south-west,
and has the village of Tregynon towards the west north-west.
When the original 200m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was listed
under the name of Bryn y Brain, with
an accompanying note stating; Name from wood
to the South.
| Bryn y Brain | 253m | SO108982 | 136 | 215 | Name from wood to the South |
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 part of the name of a near wood and prefix it with the
word Bryn. 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 C110a on the Tithe map, this 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 is named as Crasty Frain, with the details on the Tithe map appearing in the parish of Tregynon and in the
county named as Montgomery.

Therefore, the name this hill is now listed by in
the 200m Twmpau is Crasty Frain, and
this was derived from the Tithe map.
