LLANVLEWIN (LLAN-FLEWYN), a parish, in the hundred of TALYBOLION, union of ANGLESEY and county of ANGLESEY, NORTH WALES, 6 miles (N. W.) from Llanerchymedd; containing 136 inhabitants. The place, which derives its name from the dedication of its church to St. Flewyn, by whom it was original founded, in the early part of the seventh century, is situated in the north- western part of the island, and is finely sheltered on the north by a chain of hills by which it is separated from the parish of Llanvechell. It appears to have been visited, if not permanently inhabited, by the Romans, on their conquest of Anglesey,; three golden bracelets, of which two were purchased by Mr. Pennant, and a bulls of the same metal, having been found on a farm within its limits, called Ynys Gwyddel, .a few yeah prior to his visiting this part of the principality.; and in this, and also in the adjoining parish, are numerous vestiges of Saxon and Danish occupation. The ourface is boldly undulated, and the soil consequently various; the lands are for the greater part inclosed, and in a good state of cultivation; the scenery is pleasingly diversified, and from the higher rounds are obtained some interesting views. The living is a perpetual curacy, annexed to the rectory of Lienrhyddlad; and the tithes have been commuted for a rent-charge of £136. The church, a plain edifice, is beautifully situated near a small lake, and surrounded with scenery of pleasing and rural appearance. There are places of worship for Calvinistic and Wesleyan Methodists. A trifling benefaction has been given by William David, at a period unknown, for the use of the poor, who also receive a portion of a small rent-charge from Richard David's charity, in the parish of Llantrisaint.
