Digain ap Constantine was said to be the son of Constantine Corneu, King of Dumnonia, and was born in c.429[citation needed] He was believed to have had three brothers, Erbin (also sainted), Meirchion and Drustan, and possibly a sister (of unknown name).[citation needed]
Sainthood
Traditionally St Digain founded the church of that name in Llangernyw, meaning "the church of the Cornishman", in the county of Conwy in Wales.[1] The church was sited next to an already venerable yew, the Llangernyw yew. His sainthood was due being a confessor, meaning he was of remarkable virtue and confessed of the faith through writings and preachings, and has the feast day of November 21.[2]
