DOTHIE-CAMDDWR (DEUTU-CAMDDWR), a township, in the parish of LLANDEWI-BREVI, upper division of the hundred of PENARTH, county of CARDIGAN, SOUTH WALES, 14 miles (E. N. E.) from Lam-peter, containing 150 inhabitants. This place takes its name from the river Camddwr, which falls into the Towy at the junction of the counties of Cardigan, Brecknock, and Carmarthen. In 1074, a sanguinary battle was fought here, between Rhys ab Owain and Rhydderch ab Caradog, princes of South Wales, on the one side, and Gronw and Llewelyn, the sons of Cadwgan ab Bleddyn, on the other, to avenge the murder of the late prince, their grandfather, in which the latter were victorious, and Rhydderch was slain, but Owain was, nevertheless, allowed to retain the sovereignty of South Wales. On the western bank of the river Camddwr there is an ancient military work, called Castell, constructed by Owain and Rhydderch on this occasion; and the place where Gronw and Llewelyn crossed the river by a ford is still named Rhyd y meirch, " the ford of the cavalry." The ground in the neighbourhood of this place is rugged and mountainous. The township separately supports its own poor: the average annual expenditure is £44. 7.
