Senan of Laraghbrine

Saint Senan of Laraghbrine (Laithrech-⁠Briuin), County Kildare, was an Irish monk toward the end of the 6th century. His father was Fintan and his mother Dediva (also called Editua), daughter of Tren, son of Dubthach moccu Lughair, chief poet of King Lóegaire mac Néill.

He founded the monastic settlement at Laraghbryan, on lands owned by the O'Byrnes. He was a contemporary of Saint Columba and attended the Synod of Drumceat in 580. He was the eldest of Dediva's famous children, among them Saint Mainchín of Corann, Saint Caillin, Saint Felim of Kilmore, Saint Daigh of Inniskeen and Saint Femia. The Martyrology of Donegal gives his feast day as 2 September.
