Fachtna of Kiltoom

Fachtna of Kiltoom (Cill Toma, in the barony of Fore, County Westmeath) was an Irish saint who lived about 460. His father, Dubhthach moccu Lughair, was the chief ollam, the supreme learned poet, of Ireland. His brothers were all saints and church founders, chiefly in Leinster: Trian, Gabhran, Euhel, Molaisse mac Lugair, Moninne and Lonan.

The Martyrology of Donegal gives his commemoration on 14 November, together with that of his brothers Gabhran and Euhel, and the Martyrology of Gorman, for the same day, speaks of the three sons of Dubhthach. He is an Irish saint venerated locally, from the time of the undivided Church.
