monk and abbot. Of unknown place of origin, Tudy founded monasteries and worked as a missionary in Brittany. Place-names and dedications point to his activity or that of his disciples in both north and south Brittany: Île-Tudy on the mouth of the Odet (Finistère), not far from Quimper, with adjacent parishes which bear his name, probably represent the main centre of his activity. The parish of St Tudy (Cornwall) represents a monastic foundation by Tudy or his disciples, possibly in concert with Brioc, represented by the nearby parish of St Breocke, and whose companion Tudy may have been. Feast: 11 May.
