LLANGLYDWEN (LLAN-GLEDWYN), a parish, in the union of NARBERTH, lower division of the hundred of DERLLYS, county of CARMARTHEN, SOUTH WALES, 9 miles (N. W.) from St. Clear's; containing 338 inhabitants. This parish; which derives its name from the dedication of its church to St. Cledwyn, one of the sons of Brychan, Prince of Brycheiniog, is pleasantly situated on the west of the river T&f; the surrounding scenery is richly diversified, and the adjacent country well wooded; and some parts are in a high state of cultivation. D61- wylim, is a handsome modernized mansion, romantically situated in a deep vale, through which flows the Ffif, forming here a boundary between the parishes of Llanglydwen, Llanboidy, and Killymaenllwyd; the grounds are tastefully laid out, and from the house may be seen the venerable Druidical remains described in the article on Llanboidy, where they are situated. The woods surrounding D61- wylim abound with squirrels: on the estate are some indications of lead-ore, but no attempt has yet been made to work it. The living is a discharged rectory, rated in the king's books at £2. 13.4., endowed with £200 royal bounty, and £200 parliamentary grant, and in the patronage of the Crown; present net income, £96. The church, dedicated to St. Cledwyn, is a small neat edifice, and was repaired and beautified some years since, at the expense of the family at Dillwylim. There are a day school, containing from thirty to forty children of both sexes, and supported by the trustees of the late Mrs. Bevan; and a Sunday school, in which from ninety to one hundred males and females are taught gratuitously, and furnished with books, &c., by a dissenting congregation.
