"ST. KEYNE, a parish in the hundred of West, county Cornwall, 2 miles S. of Liskeard. This place was anciently called Lametton, but changed its name in consequence of a well dedicated to St. Kayne, or Keyna, the daughter of Brychan, prince of Brecknock, of which tradition says, whoever first drinks, husband or wife, gets the mastery for life. The surface is diversified with hills and the low grounds are watered by the river Loos. The soil is generally a stiff yellow clay. The village is small and wholly agricultural. The tithes have been commuted for a rent-charge of £140. The living is a rectory* in the diocese of Exeter, value (3198. The church, dedicated to St. Kayne, is a small plain edifice, and near it is St. Kayne's Well. The roof of the enclosure supports in a singular manner five trees, two of oak, two of ash, and one of elm.
