He died a violent death in 1367, 1368 or 1381, killed by the O'Mahonys or by his uncle Fitzmaurice. He died in 1381 or in 1367, killed by the O'Mahonys. Otherwise, he was killed by his maternal uncle Lord Fitzmaurice in 1368. He is the founder of the MacCarthy of Muskerry dynasty. He was probably succeeded by his eldest son Cormac as the 2nd Lord. His grandson Teige was the 6th Lord, but the 3rd, 4th and 5th lords are not known by name and might have succeeded by primogeniture or might have been chosen by tanistry.
