LLANRHYDDLAD (LLAN-RHODDLAD), a parish, in the hundred of TALYBOLION, union of ANGLESEY and county of ANGLESEY, NORTH WALES, 8 miles (N. W. by W.) from Llanerchymedd; containing 725 inhabitants. This parish, which is of small extent, is situated on the shore of the Irish Sea, which washes the western side of it: the surface is boldly varied, and the views from the higher grounds are extensive, embracing an interesting prospect over the sea and the adjacent country, which abounds with pleasing, and in some parts with picturesque, scenery. The village, called Rhydwyn, which is small, is situated about a mile from the foot of Moel Rhyddlad, one of the highest mountains in the island, and for that reason selected by Colonel Mudge as one of his principal stations in making the trigonometrical survey of North Wales. Considerable quantities of manganese, and some copper-ore, it is said, have been found upon this mountain; but no mines have been opened. Sulphur- ore has lately been discovered upon a farm called Cevn-db-bilch, about a mile east of the Moel: the mine is not however worked upon an extensive scale, and the quantity of ore raised has as yet been inconsiderable. The living is a discharged rectory, with Llanvlewin and Llanrhwydrus annexed, rated in the king's books at £14. 11. 8.; present net income £530, with a glebe-house; patron, Bishop of Bangor. The tithes of the ancient parish of Llandogvael are received alternately by the rectors of this place and Llanvechell. The church, dedicated to St. Rhyddlad, is a small edifice, not distinguished by any architectural features of importance. There are places of worship for Calvinistic and Wesleyan Methodists. A National day school, cqpimenced in 1826, and containing about 50 children of both sexes, is supported by subscription, amounting to £15 annually, paid as a salary to the master; and there are two Sunday schools, appertaining respectively to Calvinistic Methodists and Baptists, in which are about 210 males and females. The interest of several charitable donations and bequests, two of which are small portions of land, is annually distributed among the poor at Christmas. The principal of these are a bequest by William Lloyd, more than a century since, with which a piece of land near the church of Llanvair- Yngbornwy was purchased, which was exchanged in 1821, under the provisions of the act of the 55th and 56th of George III., for other lands with two cottages, containing in the whole 10 acres, and worth £11 per annum. Another is a charge of £4. 4. on property in the parish of BOdedern, arising from a bequest of Edmund Griffith; and there are also numerous small rent-charges, producing about 138. 6d. The church lands consist of several parcels, amounting in the whole to about 30i acres, and yielding a rent of £17. 16. 6. Sir William Williams, Speaker of the House of Commons in the reign of Charles II., was born in this parish, of which his father, Dr. Hugh Williams, founder of the families of Wynnstay, Bodelwyddan, and Penbedwr, was rector from 1633 till 1670.
