LLANVIHANGEL-TALYLLIN (LLANFIHANGEL-TAL-Y-LLSN), a parish, in the hundred of TALGARTH, union of BRECKNOCK and county of BRECKNOCK, SOUTH WALES, 4,1 miles (E.) from Brecknock; containing 151 inhabitants. This parish derives its name from the dedication of its church to St. Michael, and its distinguishing adjunct from its situation at the head or north-western extremity of the beautiful lake called Llangorse pool, or Llyn Savaddan. The whole of it, together with the parish of Cathedine and part of Llangorse, was assigned by Bernard Newmarch to his royal prisoner Gwrgan, son of Bleddyn ab Maenarch; but it appears to have reverted to the Norman lords of Brecknock, on the marriage of the Welsh chieftain with the heiress of Wizton, in the county of Pembroke, to which place he immediately removed. On the attainder of the last Duke of Buckingham of the Stafford family, this property was granted to John Welwyn, from whom it successively passed to the Wynters, the Philippses, the Scourfields, and the Prichards, and finally to the grandfather of the Rev. Hugh Bold, the present lord of the manor. The rateable annual value of the parish has been returned at £1084. The village is agreeably, situated at the head of the lake, which is two miles in length and one in breadth, and abounds with perch, pike, and eels, of which last some are found of enormous size. From this fine sheet of water issues the small stream called the Llynvi, which during part of its course forms a boundary between the hundreds of Pencelly and Tilgarth, and afterwards falls into the Wye just above the bridge at Glisbury. The surrounding scenery is pleasingly diversified, and in some parts highly picturesque; and the views comprehend some interesting features, among which the Brecknockshire Beacons are conspicuous. The turnpike- road from Brecknock to Llangorse and Tilgarth runs through the village; and the Brecknock and Hay tram-road passes within a few hundred yards of it. The living is a discharged rectory, rated in the king's books at £4. 12. ait.; patron, Rev. Hugh Bold: the tithes have been commuted for a rent-charge of £170; and there are 18 acres of glebe land, valued at £18 per annum, and a very indifferent parsonage-house, attached to the benefice. The church, dedicated to St. Michael, is an ancient structure, consisting of a nave and chancel, with a massive square tower at the west end, and is beautifully situated at the extremity of the lake, and kept in good repair. Adjoining the churchyard is a room, purchased and fitted up by the late rector, Archdeacon Davis, who, in 1816, established a school here on the National plan, which is, however, at present suspended for want of scholars, the parish being so small. Mrs. Mary Philipps gave by deed a house and garden in the village, the rent to be distributed in bread to the poor; but the benefaction produces only £1 per annum, the rent being low, in consideration of the tenant's supporting a large family, who would otherwise be chargeable to the parish. Mrs. Jennet Prosser also left a house and garden to the poor, which produces £2 a year; and Pwll-y-Mere, a tenement in the parish, comprising about half an acre of land, worth about £1 per annum, was bequeathed for a supply of sacramental bread and wine, to which use the rent is now applied.
