"LLANERCHLLWYDOG (LLANERCH-LWYD-OG), a parish in the hundred of KEMMES, county of PEMBROKE, SOUTH WALES, 4 miles (E.S.E.) from Fishguard, containing 169 inhabitants. This place derives its name from Clydawc one of the reguli of the county, by whom, according to Mr. Fenton, the church was originally founded, and who, while pursuing the diversion of the chase in this vicinity, was treacherously murdered, and afterwards interred in the churchyard. The parish is romantically situated on the river Gwayn, which, after pursuing a north-westerly course, falls into Fishguard bay: it comprises a large tract of land, with the exception of a mountainous district, is wholly enclosed and in a good state of cultivation. The surface is finely undulated, and the surrounding scenery is pleasingly diversified and in some parts highly picturesque. The living is a discharged rectory, with that of Llanllawer annexed, in the archdeaconry of Cardigan, and diocese of Bangor, rated in the king's books at £8, and in the patronage of Thomas Lloyd, Esq. The church, dedicated to St. David, is not distinguished by any architectural details of importance: in the churchyard are two upright stones of great antiquity, which are supposed to mark the grave of Clydawc. There are places of worship for Baptists and Calvinistic Methodists. The average annual expenditure for the maintenance of the poor is £56. 1." [From A Topographical Dictionary of Wales (S. Lewis, 1833).]
