COEDYCUMMER (COED-Y-CYMMER), a hamlet, in the pariah of VAINOR, hundred of PENCELLY, county of BRECKNOCK, SOUTH WALES, 11 mile (N. by W.) from Merthyr-Tydvil, containing 1540 inhabitants. This large village, which is situated on the borders of Brecknockshire and Glamorganshire, is of recent origin, having risen in consequence of the establishment of the iron-works in the vicinity, in which many of the inhabitants are employed. The houses are built along the sides of the road leading to Brecknock, and are scattered over part of an adjoining common, which extends between two branches of the river TIE COGAN, a parish, in the hundred of Diicts-Powis, county of GLAMORGAN, SOUTH WALES, 5 miles (8. w. by 8.) from Cardiff, containing 22 inhabitants.

The living, with those of Llandongh and Leckwith, forms a consolidated rectory, in the archdeaconry and diocese of Llandaf, rated in the king's books at £8. 8.4., and in the patronage of the Marquis of Bute. The church, dedicated to St. Peter, is at present disused: in the chancel are some ancient monuments, among which are several of the family of Herbert, of Cogan Pill, an ancient mansion now converted into a farm-house. The poor children of this parish have the privilege of attending the school at Llandough. An average annual expenditure of 3639. 15. is applied for the support of the poor.
