Saint Cainnech of Aghaboe is also known as Saint Canice in Ireland, Saint Kenneth in Scotland, Saint Kenny and in Latin Saint Canicus. He was an Irish abbot, monastic founder, priest and missionary.
He was born in 515 or 516, at Glengiven, near Dungiven in Ireland. He spent his early years watching his chieftain’s flocks. In 543 he became a pupil at Finian’s monastic school at Clonard. During the sixth century, some of the most significant names in the history of Irish Christianity studied at this monastery. Twelve students who studied under St. Finian became known as the Twelve Apostles of Ireland, Kenneth was one of these. It was at Clonard that he became a friend and companion of St Colmcille (Columba).
In 544 he studied under St. Mobhi at the school of Glasnevin, with Kieran of Clonmacnoise and St. Comgall of Bangor. When plague scattered that community, he went to Saint Cadoc’s monastery of Llancarfan in Glamorganshire in Wales, where he was ordained priest in 545. He left for Rome to obtain the blessing of the reigning pontiff. In 550 he had returned to Glengiven, where he converted his foster-brother, Geal-Breagach, who afterwards assisted him in founding Drumachose, in nearby Limavady.
In 565 he joined Columba in Scotland. He built a church in the place now known as Saint Andrew’s. He built monastic cells on the island of Ibdon and Eninis, an oratory called Lagan-Kenny on the shores of Loch Laggan, and a monastery in Fife on the banks of the Eden. His name is still recalled in the ruins of an ancient church, Kil-Chainnech on Tiree Island, in a burial ground, Kil-Chainnech, in Iona and Inch Kenneth off Mull
He spent a good deal of his time in Ireland, in County Meath and in Ossory in what is now County Laois. In Ossory he had a good repute with the king, Colman son of Feradach, who gave him grants of land including Aghaboe (“the field of the Ox”) which became his principal monastery. Aghaboe grew in importance, and in the 7th century sent St. Fergal as a missionary to the church of Salzburg, Austria. Aghaboe was for a time the site of the bishop’s see until under Norman influence in the twelfth century the see transferred from Aghaboe to Kilkenny.
He died and was interred at the Abbey of Aghaboe in 599/600.
