Lithghean of Cluain-⁠mor

Saint Lithghean of Cluain-⁠mor was an Irish saint of Cluain-⁠mór-⁠Lithghein in Uí Failghe in Leinster. He was of the Dál Cormaic and a brother of Saints Abbán and Senach of Cill-⁠mór. His mother, by one account, was Broinnfhinn Brecc, daughter of Lughna and sister of Bishop Iubhar; by another, Mella, sister of Ibar.

He is thought to be one of the seven presbyters buried at Killeen Cormac. He is remembered in the Martyrologies of Tallaght and Donegal on 16 January (the date of the martyrologies, in the Julian calendar). He is a saint of the undivided Church, honoured locally, without synodal canonization.
