NANTCWNLLE (NANT-CYNLLO), a parish, in the union of TREGARON, partly in the upper division of the hundred of MOYTHEN, and partly in the lower division of that of PENARTH, county of CARDIGAN, SOUTH WALES, 8 miles (N.) from Lampeter; containing 773 inhabitants. This parish derives its name from a small brook that flows into the river Aeron, by which it is intersected, and from the dedication of its church to Cynllo, an eminent British saint, who flourished about the middle of the fifth century. The Aeron here forms a boundary between the hundreds of Moythen and Penarth: the vale through which it runs abounds with pleasingly varied scenery, and the views over the surrounding country combine many objects of interest. The parish constitutes a prebend in the Collegiate Church of Brecknock, valued in the king's books at £7. 6. 8., and in the gift of the Bishop of St. David's:. the living is a discharged vicarage, rated in the king's books at £3.13.4., endowed with £600 royal bounty, and £600 parliamentary grant, and in the patronage of the Bishop. The tithes are divided between the prebendary and the vicar, the former of whom has two-thirds, and the latter one; and they have been commuted for a rent-charge of £175, of which £116. 13. 4. are payable to the prebendary, and £58. 6. 8. to the vicar, both portions subject to rates, together averaging £13 per annum. The church, dedicated to St. Cynllo, is a small plain edifice, consisting of a nave and chancel, and is not distinguished by any architectural details of importance. About 60 males and 60 females are instructed in two Sunday schools, supported by payments from the scholars. There are some remains of an ancient intrenchment, called " Pen-y-Gaer."
