LLANGELYNIN (LLAN-GELYNIN), a parish, in the union of ABERCONWAY, hundred of LLECHWEDD-ISAV, county of CARNARVON, NORTH WALES, 3 miles (S. by W.) from Aberconway; containing 270 inhabitants. This parish, which derives its name from the dedication of its church to St. Celynin, who flourished towards the close of the sixth century, is situated at the north- eastern extremity of the county, bordering upon Denbighshire. A memorable battle was fought at Cymryd, in the parish, in the year 880, between the forces of Anarawd, Prince of North Wales,"and those of Edred, Earl of Mereia, who attempted the conquest of the country. In this conflict Anarawd was completely victorious; be drove the Mercians from the field of battle, and continued to pursue them until finally expelled from the principality: the victory was called Dial Rhodri, or " Roderic's Revenge," as Anarawd thus fully avenged the slaughter of his father Rhodric in a descent of the Saxons upon Anglesey. The village, which is small, is beautifully situated in a fertile vale under the mountain called Tal-y-Van. The surface of the parish is mountainous, the lands partially inclosed and cultivated, the soil various, and the surrounding scenery marked with features rather of boldness than of beauty: of the rateable annual value, the return made amounts to £1101. 12. 6. The living is a discharged rectory, rated in the king's books at £7; present net income £212; patron, Bishop of Bangor. The church is a small ancient edifice, in a state of considerable dilapidation. There are places of worship for Independents and Wesleyan Methodists; also two Sunday schools, one of which, held in the church from March to September, and supported by the rector, contains about 30 children, and the other consists of about 130, and is maintained by the Independents. The Rev. Launcelot Bulkeley, in 1718, bequeathed £120, directing the interest to be appropriated to the clothing of six poor boys, and teaching them to read, two to be of this parish, and two of each of those of Caerhen and Llanbedr; and two from this place are accordingly taught and clothed in a school at Caerhen. The same benevolent individual also left a sum of £60, the interest to be paid to four widows, who are appointed at a vestry, and receive the donation.
