(often confounded with St. Cumin [q.v]), an early Irish ecclesiast of unknown parentage, was probably educated in St. Columba's monastery at Durrow, and had his church at Kilcomin ( King's County). He is known for his zeal in the Paschal controversy, and a letter of his is extant on the subject, written A.D. 634 (given in Usher, Works, 4:430). He is also thought to be the author of an abridgment of the penitential Psalms (in Fleming, Collect. Sacra, page 197).
