(supp. fl. early 8th century)
Patron saint of Congresbury (Cungres-byrig) in Somerset, to which it supposedly gave its name. His origins are obscure. It has been suggested that he was originally a Welsh/British saint, and/or that he was invented to explain the placename and equip Congresbury with an origin story, based perhaps on a version of the Welsh saint. His vita shows certain affinities with 12th-century Welsh Latin hagiography associated with Caradog and the monastery of Llancarfan.
