History

The MacGeraghty clan are descended from the Siol Muireadaigh of the Kingdom of Connacht, the same Gaelic lineage and homeland as the Ó Conchubhair dynasty. Their lands were originally situated in the Barony of Roscommon. They were rulers of Clann Tomaltaigh and the Muintir Roduib and are referred to in the topographical poem Tuilleadh feasa ar Éirinn óigh by Giolla na Naomh Ó hUidhrín. Members of this Clan are said to have named the island of Innis Murray after themselves as they were formerly chiefs of the Siol Murray. The MacGeraghty clan are associated with the Gaelic Kingdoms of Uí Briúin and Uí Maine, in the latter they were second only to the O’Ceallaigh, who were the Kings of Uí Maine. A Chief of the name, called McGiriaght is listed in the Composition Book of Connacht in 1585, as seated in the Barony of Athlone. Geoffrey Keating’s History of Ireland records that: "Mac Oiraghty of the steeds was the ruling chief of Muintir Roduiv of rightful laws - A fearless warrior as he ranged the woods" The clan name MacGeraghty lead to the anglicised name Geraghty, descendants of the family are still found in large numbers in County Galway, County Mayo, County Roscommon, County Sligo and among the Irish diaspora.
