LLANVAIR-MATHAVARNEITHAV (LLAN-FAIR-MATHAFARN-EITHAF), a parish, in the hundred of TYNDAETHWY, union of ANGLESEY and county of ANGLESEY, NORTH WALES, 7 miles (N. W. by W.) from Beaumaris; containing 741 inhabitants. This parish is situated on the shore of the Irish Sea, which bounds it on the east; on the north it is bounded by the parish of Llaneugrad, on the south by Llanddyvnan, and on the west by Tregayan; and it comprises by measurement 1654 acres, of which about 1000 are arable and pasture land. The soil is light, resting for the most part on a substratum of limestone; and the surface, though not level, is yet not hilly; in particular situations the view of the sea is of very great extent. The lands under tillage are in a good state of cultivation, but wheat is very little sown, the chief produce being oats and barley; several good houses have been erected on the common lands, which have been recently inclosed. Black, grey, and variegated marble exist within its limits, the last of which is of very superior quality, and possesses a great variety and brilliancy of colour, and is susceptible of a high degree of polish. There is a small mill-stone quarry in the parish, in which about fifteen hands are employed in raising and chiselling the stone. The living is a perpetual curacy, annexed to the rectory of Llanddyvnan: the tithes have been commuted for a rent-charge of £109. 19. 7. The church, dedicated to St. Mary, is a very old building, and at present in great want of repair. There are places of worship for Calvinistic and Wesleyan Methodists; also four Sunday schools, in one of which are 150 males and females, who attend the Established Church; the others appertain to dissenters, and contain nearly 230; all are instructed gratuitously, and books and clothing are provided for the poorest. The interest arising from some small charitable benefactions, the principal of which were £8. by Thomas Owen, and a simistrm by Thomas John Price, the whole amounting to £17, is annually distributed among the poor, together with £2. 4., the proportion payable to tins place from John Williams's charity in the parish of Llaneugrad. In a small cottage in the parish the celebrated bard Goronw Owen was born, on the 1st of January, 1722. He obtained in the free school 'of Bangor the rudiments of an education which he 'afterwardsconspleted at Jesus' College, Oxford, and was appointed by the Bishop of Bangor curate of his native parish. He afterwards removed to Oswestry, and subsequently to Northolt, in Middlesex; but meeting with no preferment in the church adequate to the support of his family, he obtained from the Cymrodorion Society a sum of money, with the assistance of which he emigrated to Williamsburg, in Virginia, of which church he was appointed minister, where he died in 1769. His discourses were eminently distinguished for originality and brilliancy of conception, and his acquirements in classical and oriental literature were of no ordinary extent; his " Search after Happi,- nese," and his " Day of Judgment," are said to be unrivalled by any similar production of the last century. A sum of money has been raised by his countrymen for the purpose of erecting a monument Ito his memorr.
