St. Congall, Abbot in Ireland
HE was abbot of Iabhnallivin, on the upper part of the lake Erne, of which parish he is titular patron. Before his death he committed the government of his monastery to his beloved disciple St. Fegnarnach. In that territory his festival is a holyday of precept, as Colgan assures us, on the 27th of July.
