"LLANWNNOG (LLAN-WYNNOG), a parish in the lower division of the hundred of LLANIDLOES, county of MONTGOMERY, NORTH WALES, 6 1/2 miles (W. by N.) from Newtown, containing 1355 inhabitants. The name of this place is derived from the dedication of its church to St. Gwynnog, an eminent member of the congregation of Catwg, who flourished about the middle of the sixth century, and was canonized after his decease. The parish is bounded on the south by the river Severn, which is joined near Caer-Sws, in this parish, by the Tarannon stream, which descends into it through the Vale of Treveglwys. ...'
