Bodfan was a 7th-century Welsh monk and saint. The son of Helig ap Glanawg, he reportedly turned to a religious life after witnessing the sea flood his family's territory. He resided on Bardsey Island before founding the initial church at Llanaber. His brothers, named Brothen, Celynin, and Rhichwyn, are also recognized as saints with churches dedicated to them in the regions of Conwy and Gwynedd.
