Breton saint. He is patron of several Breton churches and his name forms part of several place-names there such as Saint-Congard, Roscongar, Lescongar. Feasts of Congar in Brittany are kept on 13 February and 12 May. This makes it unlikely that he is to be identified with either of the others, but Doble identifies the Breton Congar with St Ingonger of Lanivet (Cornwall), and suggests that Petroc, Congar, and Cadoc were ‘brothers’ in a great missionary enterprise.
