RHOSCROW-THER (RHOS-YCRYTHOR), a parish, in the hundred of CASTLEMARTIN, union of PEMBROKE and county of PEMBROKE, SOUTH WALES, 5 miles (W.) from Pembroke; containing 209 inhabitants. This place is said to have been anciently the residence of some of the Welsh princes, prior to the Norman conquest; and there is still a spot called Estington, supposed to be a corruption of " Iestyn's-ton," which was probably their abode. The parish is situated near the shores of Milford Haven, and bounded on the north by Angle bay and the parish of Pwllcrochon, east by Monkton, south by Castlemartin, and west by Angle; and contains by admeasurement 2366 acres, nearly equally divided between pasture and amble, the latter producing the usual kinds of corn. There is no timber, and the surface is rugged; but the views over the haven and St. George's Channel are sometimes interesting, and enlivened by the passing and repassing of vessels. The rateable annual value of the property is returned at £1709. The living is a rectory, rated in the king's books at £15. 12. 11., and in the patronage of the Crown: the tithes have been commuted for a rent-charge of £280; and there is a glebe of 75 acres, valued at £112 per annum, with a glebe-house. The church, dedicated to St. Decumanus, is partly of very great antiquity, in the early style of English architecture, but the body of the structure is modern, about 70 feet long by 18 wide, and containing 120 sittings, of which 20 are free.
