RHY-WAEDOG (RHIW-WAEDOG), a township, in the parish of LLANVAWR, hundred of PENLLYN, county of MERIONETH, NORTH WALES, 2 miles (E. S. E.) from Bala: the population is in-eluded in the return for the parish. The name signifies " the bloody brow," and refers to a battle fought here at some remote period, and ,the peculiar situation of the place on the ridge of a lofty eminence. Pwll y Gelanedd, or "the pool of the slain," is a small lake of stagnant water in a contiguous vale, where a severe contest was maintained between the Britons and the Saxons, in which the only surviving son of the aged Llywarch was slain. A church, parsonage-house, and National school, were built in the township a few years since by the Rev. W. Cleaver, rector of the parish.
