      Description & Travel

      LLANTRISAINT (LLAN - TRISANT), a parish partly in the hundred of MEDIAL but chiefly in that of LLYVON, county of ANGLESEY, NORTH WALES, 4 miles (W.) from Llanerchymedd, containing 537 inhabitants. This parish, which is situated in the western part of the island, and is intersected by the small river Alaw, comprehends a tract of about four thousand four hundred and sixty acres of arable and pasture land, of which the greater portion is enclosed. The surface is boldly undulated, rising into abrupt eminences of various elevation and aspect : the soil is for the most part poor, consisting chiefly of a hungry clay, fit only for the cultivation of oats. Copper-ore has been found in considerable quantities upon Meinir farm ; but no mines of it have hitherto been opened. The living is a discharged rectory, with the perpetual curacies of Ceidio, Gwredog, Llanllibio, and Llechcynvarwydd annexed, in the archdeaconry of Anglesey, and diocese of Bangor, rated in the king's books at £ 15, and in the patronage of the Bishop of Bangor. The church, dedicated to St. Avran, St. Ieuan, and St. Sanan, from which circumstance the parish derives its name, signifying the church of three saints, was originally founded in the year 570. The present is a good modern edifice of comparatively recent erection : it contains a neat plain monument to the memory of Dr. Hugh Williams, founder of the families of Wynnstay, Bodelwyddan, and Penbedw. There is a place of worship for Calvinistic Methodists. A small parochial school for the gratuitous instruction of poor children was founded in 1822: it has an endowment of £8 per annum, for which ten children are taught reading, writing, and arithmetic : the instruction of others is paid for by subscription. Three poor men from this parish are eligible to the alms-houses at Beaumaris, under the will of the founder, David Hughes, who endowed them with the farm called Meinir, here situated, and with various other lands for the support of the inmates. The same benefactor, by his will, dated December 30th, 1609, after providing for the maintenance and support of the school and almshouses at Beaumaris, directs that any surplus should be distributed among the poor of this parish ; but although a considerable surplus has been accumulating for many years, no distribution has yet been made. The affairs of the charity are at present under the investigation of the Lord Chancellor, and it is expected that a very considerable distribution will eventually be made among the poor, according to the tenour of the will. The above-named David Hughes was a native of this parish, and having by persevering industry amassed a very ample property, thus charitably appropriated a considerable portion of it for the benefit of the poor. The average annual expenditure for the support of the poor is £293. 13. ( A Topographical Dictionary of Wales 1833 by Samuel Lewis)

      GWREDOG, a chapelry in that part of the parish of LLANTRISAINT which is in the hundred of MENAI, county of ANGLESEY, NORTH WALES, 2 miles (N. by E.) from Llanerchymedd. The population is returned with the parish. This small chapelry, which consists only of two farms, is situated in a very retired part of the county, and is not distinguished by any feature of interest or importance. The living is a perpetual curacy, annexed to the rectory of Llantrisaint, in the archdeaconry of Anglesey, and diocese of Bangor. The chapel, dedicated to St. Mary, is a very small and plain edifice, occupying a solitary situation, almost inaccessible in winter, and without any road leading to it. One poor man of this place is eligible to the almshouses founded at Beaumaris, in 1609, by Mr. David Hughes, who also founded and endowed the free grammar school of that place.
