LLANLLWCHAIRN (LLAN-LLWCHAIARN), a parish, in the union of ARERAARON, lower division of the hundred of MOYTHEN, county of CARDIGAN, SOUTH WALES, 7 miles (W. S. W.) from Aberaeron; containing 1475 inhabitants. This parish, which is situated on the shore of Cardigan bay, has, from its advantageous maritime position, risen into some degree of notice, and is rapidly increasing in population and importance. It is traversed by the road from Cardigan to Aberystwith; and is bounded on the east by the parish of Llanina, on the south-east by that of Llanarth, and on the south by that of Llandysilio-Gogo. The computed number of acres is 3000, of which about 1500 are arable, 100 meadow, and the remainder pasture and waste; and the lands consist of large open tracts, nearly bare of wood, and possessing no scenery of interest, but commanding fine views of the sea. l'he soil is various, but a grey light earth is most prevalent, alternating occasionally with portions of clay; and the chief agricultural produce is grain: building-stone of excellent quality is wrought in several places, and near New Quay is a very large quarry, from which blocks of stone have been raised 30 feet in length and 14 tons in weight. Soles, turbot, and oysters are found in great abundance and of superior quality on this part of the coast, and a herring fishery might be advantageously established here, if an adequate demand existed. The trade of the place has already increased so much, as to give rise to the establishment of the small port of New Quay (described under its own head), which has already attained a considerable degree of celebrity, and maintains a regular intercourse with Bristol. The living is a discharged rectory, rated in the king's books at £6. 7. 8k.; present net income, £180, with a glebe-house; patron, Bishop of St. David's. The church, dedicated to St. Llwchaiarn, is situated about a quarter of a mile from New Quay, and is an ancient edifice, in the early English style, consisting of a nave and chancel, separated by a pointed arch; the nave was once embellished at each angle with the king's arms carved in wood, but all that now remains is the motto, with the date, 1621; the font, which is of great antiquity, is square, and ornamented at each angle with a human head: the edifice is 68 feet in length and 18 in breadth, and contains about 350 sittings, nearly half of which are free; but on account of the increase of the population, the accommodation is insufficient, and a church of larger dimensions is considered necessary. The parsonage-house is contiguous; and in the churchyard, which commands a delightful view of the sea and the Carnarvonshire mountains, are the remains of a stone cross. There are places of worship for Independents and Calvinistic and Wesleyan Methdia.& About 90 children of both sexes are taught in two day schools at the expense of their parents; and there are four Sunday schools, conducted gratuitously, in one of which are 120 children, who attend the Established Church; the rest appertain to the dissenters, and afford instruction to about 320 males and females. There are some trifling vestiges of an ancient earthwork, "called Pencastell, in the parish.
