Cellach

Saint Cellach (Ceilach, Keilach) was abbot of Iona in Scotland and founded the monastery of Kells; later he was archbishop of Armagh in Ireland in the ninth century. Our record gives his death in the year 815. He is not to be confused with Saint Cellach, archbishop of Armagh in the twelfth century (1080 to 1129), nor with Saint Cellach of Glendalough, commemorated on 7 October. He is a saint of the undivided Church, commemorated on 1 April (new style; 14 April in the old style).
