LLANGWYVAN (LLAN-GWYFAN), a parish, in the hundred of MALLTRAETH, union of ANGLESEY and county of ANGLESEY, NORTH WALES, 9 miles (S. W. by W.) from Llangevni; containing 193 inhabitants. This parish, which is of very small extent, being scarcely a mile in length, and about the same in breadth, is situated at the south-western extremity of the county, on the shore of Carnarvon bay; and is bounded by the parishes of Lianbeulan and Llanvaelog on the north, on the south by that of Aberfraw, and on the west by the sea. It comprises about 1500 acres, three-fourths of which are arable, and the remainder pasture; the surface is gently undulated, and the soil is rich and fertile, producing excellent crops of wheat, barley, and oats, which, with sheep, cattle, and pigs, constitute the chief disposable stock. Phis Llangwyvan, an ancient mansion, is the property of Owen Fuller Meyrick, Esq., lord of the manor and owner of the parish. The living is a perpetual curacy, annexed to the rectory of Travdraeth: the tithes have been commuted for a rent-charge of £242, subject to rates, averaging £3. 3.; and there is a glebe of four acres, valued at £3 per annum. The Church, dedicated to St. Cwyvan, who nourished towards the close of the seventh century, and from whom the parish derives its name, is a small edifice, 48 feet long and 27 broad, and contains about 250 sittings, nearly all of which are free; it is built on a rocky island in Carnarvon bay, about three-quarters of a mile distant from the main land, with which it has a communication only at low water; and during the prevalence of easterly winds is utterly inaccessible, on which account divine service is seldom performed in it during the winter months. There is a Sunday school, in which from 20 to 30 children receive gratuitous instruction. The produce of some small charitable gifts in land and money is annually distributed among the poor; the principal of which is the grant, by Margaret Wynne, of the farm of Cevn Bychan, in the parish of Newborough, containing thirty acres, now let at £9 per annum, to two poor aged women, one of this place, and one of Llanbedr-Goch, the recipient of the bounty in this parish to be selected by the owner of the mansion of Rhos Mor: there is also a rent-charge of 10s. for the use of the poor, payable out of Cae Gwyn, in the parish of Llanvaelog, the property of Lord Boston; and several other small benefactions, which produced £2. 3. 6. annually, have been lost.
