BRYN-GWYN, a parish in the hundred of PAINSCASTLE, County of RADNOR, SOUTH WALES, 6 miles (N.N.W.) from Hay, containing 364 inhabitants. This parish is situated on the small river Garrow, or Arrow, and contains some large tracts of fertile and productive land in a good state of cultivation, and a considerable portion of common, part of which is a turbary, called Rhos Goch, producing very fine peat, which is dug to the depth of fifteen feet from the surface. Beneath the peat are strata of blue clay and of a clay of a yellow hue, the latter abounding with sea shells, which crumble on the slightest touch : the layer is about two feet in depth, and appears to be incumbent on water, which rises up through the fissures occasionally made with the spade, and soon fills the whole cavity. The living is a rectory, in the archdeaconry of Brecknock, and diocese of St. David's, rated in the king's books at £ 11. 6. 8., and in the patronage of the Bishop of St. David's. The church, dedicated to St. Michael, consists of a nave and chancel, but is not distinguished by any architectural features deserving of notice. Richard Jones, in 1706, and an unknown benefactor, gave each a portion of land, directing the rental to be distributed among the poor of this parish. The average annual expenditure for the support of the poor amounts to £204.3.
