Luchtigern (Latin: Luctigernus) was an early Christian leader who was active in Ireland in the 6th century, and has been recognized as a saint by the Catholic Church.
An old ruined church in the Ennistymon burial ground, although more recent, most likely marks the location of the abbey.
[5] He accompanied MacCreiche to Carn Mic Táil to give advice to the Corca Modruadh and Tuadhmhumhain people over a tribute of cattle that the king of Connaught was demanding.
[9] A traditional story tells of Luchtigern curing a woman inflicted by the plague, who came to him when he was working in the field at Tomfinlough with two deacons.
The "plague stone" with its three bosses, one flat and two round, is part of the Tomfinlough graveyard wall, and may be seen today.
