PENRHOS-LLIGWY, a parish, in the hundred of TWRCELYN, union of ANGLESEY and county of ANGLESEY, NORTH WALES, 5 miles (E. N. E.) from Llanerchymedd; containing 524 persons. This parish, situated near the shore of the Irish Sea, is of very considerable extent, and is principally distinguished for the fine quarries of Mona marble with which it abounds, and in the procuring of which several of its inhabitants find constant employment. A small creek running up from Dulas bay affords every facility for conveying the produce to the shipping-place there, from which great quantities are sent to London and Liverpool. At a short distance from the mouth of the bay, which forms a very commodious harbour, is a little island called Ynys Gadarn, a lofty rock of marble, on which is placed a beacon, lately enlarged by Colonel Hughes, of LlYsdulas, to direct mariners in their navigation of these dangerous coasts, and to point out an object that has often proved fatal to those unacquainted with this part of the shore. A part of the population is also engaged in carding and spinning wool, of which a small manufactory is carried on in the parish. The living is a perpetual curacy, endowed with £200 private benefaction, £800 royal bounty, and £500 parliamentary grant; net income, £75; patron and impropriator, Lord Boston. The church, dedicated to St. Michael, is a neat modern structure; in the churchyard are two ancient sepulchral stones, with inscriptions in very rude and antique characters, of which one is noticed by the author of the "Mona Antigua Restaurata," as covering the grave of Mechell, or Macutus, grandson of one of the lords of Gloucester, Bishop of St. Maloes, and founder of the church of Llanvechell, in this county, who was massacred at Stonehenge. There is a day school, in which about 20 males and females are instructed at their parents' expense; also a Sunday school in the church, where from 100 to 120 males and females are gratuitously taught to read the Welsh language. Owen Lloyd, Esq., merchant, of London, in 1665, bequeathed a farm in the parochial chapelry of Iecoed, near Wrexham, consisting of about sixty-one acres, directing the income to be applied to the apprenticing of poor boys of this parish to some trade or calling in London; the same gentleman left also £400 to be laid out in the purchase of land for the endowment of two exhibitions in the University of Oxford, for one boy a native of this place, and one a native of any part of the Isle of Anglesey. The rental of the farm is now £70 per annum, which is applied to the apprenticing of three boys with premiums of £10 each; the exhibitioners, who receive £20. 16.per annum, are appointed by Mr. Meyrick, of B6dorgan. There are also some small charitable donations and bequests for distribution among the poor, the principal of which is a rent-charge of £3, payable out of a farm called Prys-dolphin, the property of Lord Boston. Of other benefactions, amounting to £8, the greater portion was stolen out of the parish chest about twenty-five years since, and the residue was expended towards erecting a cottage on the common, now occupied by a family rent-free. Lligwy, in the parish, the ancient seat of the family of Llwyd, and now the property of Lord Boston, has been a venerable mansion celebrated for the extensive woods surrounding it, of which at present there are but very small remains, the woodlands being now covered only with small brushwood and brambles, and the mansion almost in ruins. On the same estate are some vestiges of an ancient chapel, situated on an eminence overlooking the bay of Llysdulas; the architecture, which is of the very rudest kind, bears testimony to its great antiquity; it is said to have been a private chapel belonging to the mansion, or a chapel of ease to Llaneugrad and Llanallgo. On digging out a fox that had taken shelter in the ruins of the building, a large square vault was discovered, containing several human skeletons, which, on exposure to the air, crumbled into dust; and, on searching further into the interior, the ground that it inclosed was found to consist of a large mass of human bones, several feet in depth, and protected only by a covering of plaster, which formed the floor of the chapel. About a quarter of a mile to the south of these rains is a very large cromlech, said to be the largest in the island; the table-stone is nearly eighteen feet in length and sixteen feet in breadth, and is supported on five low upright stones, having one end resting upon a rock; the relic is called by the country people Arthur's Quoit. Lewis Morris, an eminent antiquary, poet, and man of science, was born in the parish, in 1702: he was employed by the Lords Commissioners of the Admiralty to make a survey of the coast of Wales, which was completed and printed in 1748; and he also left a work which he called the " Celtic Remains," still unpublished, with an immense number of manuscripts, of which eighty volumes are deposited in the library of the Welsh charity school in Gray's Inn Lane, London. Richard, his brother, distinguished himself as a Welsh critic and poet of considerable talent; he spent the greatest part of his life as first clerk in the Navy Office, during which time he superintended the printing of two valuable editions of the Welsh Bible.
