BONVILSTON, otherwise BOLSTON, a parish, in the hundred of DINASPOWYS, county of GLAMORGAN, SOUTH WALES, 4 miles (E.) from Cowbridge, on the road to Cardiff, containing 247 inhabitants. The village, which is pleasantly situated, is ornamented with several neat cottages, and with the ancient residence of the family of Bassett, and has a prepossessing appearance of cheerfulness and gentility. Limestone of good quality abounds in the parish. The living is a perpetual curacy, in the archdeaconry and diocese of Llandaf, rated in the king's books at £ 6.9. 2., and endowed with £15 per annum, principally issuing out of the small tithes, and £200 private benefaction, £200 royal bounty, and £500 parliamentary grant, and in the patronage of John James Bassett, Esq. The church, dedicated to St. Mary, is a neat and appropriate structure. Grace Aubrey, in 1678, bequeathed £100, Mrs. Loughor £50, and Mr. David John, in 1776, £10, for the use of the poor, making together the sum of £160, to which £3 per annum has been subsequently added, arising out of two deed polls, purchased with ten years' arrears of Grace Aubrey's donation, according to an inscription on a tablet in the church. There is said to have been formerly a castle here, the site of which is still pointed out, but no account of its foundation, nor any particulars of its history, have been recorded. The average annual expenditure for the support of the poor amounts to £115. 16.
