Bryn (ST 008 824)
There has been a Significant Name Change to a hill
that is listed in the 100m Twmpau,
with the summit height, bwlch height and their locations, the drop and status
of the hill confirmed by LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the list that this name change applies to
are:
100m Twmpau - Welsh hills at or above 100m and below 200m in height with 30m
minimum drop, with an accompanying sub list entitled the 100m Sub-Twmpau with the criteria for this sub category being all
Welsh hills at or above 100m and below 200m 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 Bro Morgannwg group of
hills, which are situated in the southern part of South Wales (Region C,
Sub-Region C2), and it is encircled by roads with the A473 to its north and
minor roads to its west and south, with the M4 motorway further to the south, and
has the small community of Llanharan towards its north-west.
The hill originally appeared in the 100m P30 list
on Geoff Crowder’s v-g.me website under the partly invented and transposed name
of Pen Coed-y-bryn, with an accompanying
note stating; Name from wood to the South-West.

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 wood and add the word Pen to it. 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 this hill comprises bounded land the Tithe map
was consulted. 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 215 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 Brynn & Nursery in the apportionments, with the details on the Tithe map appearing in the parish of LLanharran [sic] and in the county named as Glamorgan.

Therefore, the name this hill is now listed by in
the 100m Twmpau is Bryn, and this was
derived from the Tithe map.
