The Clan/Sept History

Mac Raith comes from the Gaelic word "raith", which means ' grace' or 'prosperity'. There were two different septs of this clan. The first was located in the region of counties Donegal and Fermanagh and was the hereditary guardian of St. Daveog's monastery in Lough Derg. The second sept was located in the regions of counties Clare and Limerick where they were poets for the Kings of Thomond. The name is among the 100 most numerous in Ireland, and is common particularly in counties Tyrone, Tipperary and Waterford.
