LLANGAFO (LLAN-GAFFO), a parish, in the union of CARNARVON, hundred of MENAI, county of ANGLESEY, NORTH WALES, 5 miles (N. W. by N.) from Carnarvon; containing 139 inhabitants. This parish derives its name from the dedication of its church to St. Caffo, who flourished in this part of Wales about the middle of the sixth century. It is situated on the road leading from Newborougb to the great Holyhead road, and which crosses it a little to the south-east of Llangevni; and is bounded on the north and north-west by the parish of Treydraeth, which is separated from it by the Malltraeth river, on the south- west and west by the parishes of Llangeinwen and Newborougb, and on the east and south-east by that of Llanidan. It comprehends an extensive tract of land, of which a large portion is marshy, some part hilly, and the remainder inclosed, and in a fair state of cultivation. In 1790, an act of parliament was obtained for more effectually embanking the marshes called Malltraeth and Cors Ddeugae, under the provisions of which two hundred and thirty acres were allotted to the several owners of property in this parish. The arable land comprises by admeasurement 1007 acres, and the pasture 504; the soil is in general fertile, and the lower grounds afford excellent pasturage for cattle: the surrounding scenery, though pleasingly varied, is not distinguished by any peculiarity of feature, but the higher grounds afford some fine views over the adjacent country. About half a mile from the church is situated the ancient mansion of Dinam, the residence for a very long period of the ancestors of the Rev. Richard Pritchard, rector of LlanvairPwllgwyngyll and Llandysillio, who now occupies it. The living is a perpetual curacy, annexed to the rectory of Llangeinwen; and the tithes have been commuted for a rent-charge of £205, subject to rates, averaging £6 per annum. The church, a small ancient edifice, situated on an eminence overlooking the Malltraeth marsh, is appropriately fitted up for the performance of divine service, and contains about 120 sittings, of which 80 are free, but is not distinguished by any architectural details of importance. Many poor children of the parish attend the Sunday school held in the Calvinistic Methodists' chapel on the borders of the neighbouring parish of Llangeinwen. Some small charitable donations have been made at various times, the principal of which are, a bequest, in 1623, of a rent-charge of 52s. to be distributed every alternate Sunday in bread, by Lewis Owen, Esc). of Twickenham, payable out of the lands of Dinam in this parish; and two benefactions, one of £20 by the Rev. Thomas Holland, and another of £10 by Owen Cadwallader, the interest of both which sums, together with 5s. from some other bequest, is paid 17 Holland Griffith, Esq. of Berw, and distributed in small sums at Christmas among such poor as receive no parochial aid. Two gold coins of the Emperor Constantine, in a good state of preservation, were found near the church, in the year 1829; and several silver and copper coins of that and other emperors have been discovered.
