Caidoc and Fricor

Saints Caidoc and Fricor were Irish missionaries (Welsh, according to Alcuin) who preached in Picardy in France. According to the life of Saint Richarius written by Alcuin, they were sheltered in Ponthieu by Richarius, then still a pagan, who became a Christian under their influence; the local people treated them with hostility, blaming them for crop failure. No detailed life of them survives. They are saints of the undivided Church, commemorated on 1 April (new style; 14 April in the old style).
