Beuno a Welsh saint, son of Hywgi (or Bugi), was a near relative and contemporary of St. Kentigern. He founded a religious society at Clynog Fawr, in Carnarvonshire, about 616, on land granted by Cadfan. In his old age Beuno was the instructor of St. Gwenfrewi (or Wenefred). Eleven churches are dedicated to him, and his festival is on April 21. See Rees, Welsh Saints, p. 268.
