Berwyn (or Gerwyn)
Berwyn (Or Gerwyn)
a Welsh saint, a son of Brychan who is said to have settled in Cornwall, but is difficult to identify, unless he is the same as St. Garonus, a hermit who preceded St. Petrock at Bodmin. Another account (Rees, Welsh Saints, p. 142) makes Gerwyn a son of Brynach by Brychan's daughter.
