Constantine of Strathclyde
Son and successor of King Riderch Hael of Alt Clut
Who they were
Constantine was reputedly the son and successor of King Riderch Hael of Alt Clut, the Brittonic kingdom later known as Strathclyde. (The modern English name of Alt Clut is Dumbarton Rock.) He appears only in the Life of St. Kentigern by Jocelyn of Furness, which regards him as a cleric, thus connecting him with the several obscure saints named Constantine venerated throughout Britain.
