LLANRHWYDRUS (LLAN-RHWYDRYS,) a parish, in the hundred of TALYBOLION, union of ANGLESEY and county of ANGLESEY, NORTH
WALES, 8 miles (N. W.) from Llanerchymedd; containing 158 inhabitants. This parish is situated at the northwestern
extremity of the Isle of Anglesey, on a headland projecting into the Irish Sea, on the north, and forming on the east the
boundary of Ceml'n bay. It derives its name from the dedication of its church to St. Rhwydrus, by whom it was originally
founded in the sixth century, and contains a large portion of inclosed and well-cultivated land. The surrounding scenery
is strikingly diversified, and in some parts highly picturesque; and the views along the coast and over the adjacent
country are interesting and extensive. About two miles north-westward from the main land is Ynys y Moelrhoniaid, or the "
Isle of Seals," commonly called Skerries, a long island composed entirely of craggy pointed rocks, in which are great
numbers of rabbits, and which, during the breeding season, is the resort of puffins and razor-bills. A lighthouse,
exhibiting a steady light, was erected on the highest point of the island, in 1783, by the Corporation of the Trinity
House, to facilitate the navigation of this part of the channel, and for the preservation of the numerous vessels employed
in the trade between Liverpool and Dublin: it has been of material use in the preservation of life and property, but the
want of a superior elevation to render it visible at a greater distance has much tended to diminish the benefits it might
otherwise have afforded. A more eligible situation might be found on the main land, at a point called Ceder Rhwydrus,
where the light would have an elevation of nearly a hundred feet above that which it has in its present situation. The
Isle of Skerries anciently belonged to the monks of Bangor, and was the principal fishery appertaining to that see, the
prelates of which, by neglect, having suffered it to be usurped by the family of Griffith, of Penrhyn, Bishop Dean, in
1498,-exerted himself for its recovery, and, after a considerable struggle, succeeded in procuring its restoration 'to the
see. The living is annexed to the rectory of Llanrhyddlad; and the tithes have been commuted for a rent-charge of £156.
3., subject to rates, averaging £5. 7. per annum. The church is a small ancient edifice, situated nearly in the centre of
the headland projecting into the sea, near the small 87 island called the West Mouse. There are places of worship for
.Calvinistic and Wesleyan Methodists; and a Sunday school, attended by from 70 to 80 males and females, is supported by
voluntary. contributions. John Hughes, in 1778, bequeathed £50 to the poor; but his widow having died in indigent
circumstances, nothing has been received by the parish from this donation.
