LLANVIHANGEL-ABERCOWIN (LLANFIHANGEL-ABER-CYWYN), a parish, in the higher division of the hundred of DERLLYS, union and county of CARMARTHEN, SOUTH WALES, 9 miles (S. W. by W.) from Carmarthen; containing 809 inhabitants. The parish derives its distinguishing appellation from its situation on the Cowin, near its confluence with the TA both of which rivers partly bound it on the east and west; and is intersected by the turnpike-road from Carmarthen to St. Clear's, from which last it is distant about two miles and a half to the south-east. Within its limits is a village, forming a kind of suburb to St. Clear's, and it derives a considerable portion of traffic from its situation, and an air of cheerfulness and activity from the frequent passing of travellers. Fairs are held annually on the 12th of May and the 10th of October. The living is annexed to the vicarage of Mydrim: of the commutation for tithes the amount is £506 per annum, of which £439 are payable to the Archdeacon of St. David's, subject to rates, averaging £57. 8. 10.; and £67 to an impropriator, also subject to rates, which average £4. The church, dedicated to St. Michael, stands very near the confluence of the rivers, but is not distinguished by any architectural features. There are places of worship for Baptists and Welsh Calvinistic Methodists: about 30 children are instructed in a day school, at the expense of their parents; and there are three Sunday schools, two appertaining to Calvinistic Methodists and one to Baptists, in which 200 males and females are gratuitously taught. A rent-charge of £10 on some farms in the neighbourhood, bequeathed by Lady Drummond, in the 25th of the reign of Charles IL is annually distributed among the poor, according to the will of the testatrix. Somevery imperfect vestiges of an encampment are visible on a farm near-Treventy, in this parish.
