Kevin of the Glen...
Saint Kevin (Caoimhghin or Cóemgen from Old Irish cóem that means “kind, honest, and handsome” and gein that means birth) was known as the founder and first abbot of Glendalough in County Wicklow, Ireland. There is not much known about St. Kevin, but it is believed that he was descended from royalty. He was baptized by St. Cronan and educated by St. Petroc.
He was supposed to have lived in Kilnamanagh (church of monks) at the age of 24 before moving on to accompany his followers. At some point he would live in solitude for seven years at Disert-Coemgen sleeping on a dolmen or a portal grave.
St. Kevin had so many followers that Glendalough became one of the prominent cities in the desert. It is now incorporated in Dublin. It became one of the Seven Churches that would be visited by pilgrims for centuries to come.
