The “first born of the saints of Ireland,” sometimes listed as Kieran Saighir or Kevin the Elder. He was a native of Ossory, and after living for a time as a hermit, he is believed to have been consecrated a bishop by St. Patrick, taking his place as the first bishop of Ossory. Another tradition states that he was consecrated in Rome. Legends attribute remarkable miracles to Kieran. His feast day is 5th March.
