A holy man is recorded, in the Martyrology of Tallagh, at the 24th of March, as Lughaidh, mac Eachach. He is classed, among the disciples of St. Columkille.  The Bollandists pass him over, with a few brief remarks. We are told, that Lugaid Mocu-Theimne, or “the son of Teimne,” was the son of Eochaid, son of Ulan, son to Eogan, son to Niall of the Nine Hostages, as his paternal pedigree has been traced, in the Genealogies of the Irish Saints. He was a relation of St. Columba, and his companion, when the latter first set out on his voyage to the shores of Britain. As we are informed, by the Martyrology of Tallagh, this saint belonged to Cluain Laigh. This place is at present called Clonleigh, meaning the “pasturage,”  “lawn,” or “insulated meadow of the calves.” This parish is situated, on the western bank of the River Foyle, about two miles northward from Lifford, in the barony of Raphoe, and in the county of Donegal, formerly Tyrconnell. There was a monastery of considerable importance, in this place. Marianus O’Gorman and Cathal Maguire have this holy man, in their respective Calendars. On this day is entered, likewise, in the Martyrology of Donegal, Lughaidh, son to Eochaidh, of Cluain-laogh.
