Overview of Rathcroghan Clans

A branch within the royal Uí Briúin (Uí Briúin Aí) dynasty, the tribe of Síol Muireadaigh consisted of all the descendants of Muiredach Muillethan, a 7th-century King of Connacht. The term Síol denotes the seed, or descendants, of Muiredach. According to historian C. Thomas Cairney, the Síol Muireadhaigh were the chiefly family of the Uí Briúin tribe of Connachta who in turn were from the Gaels, the fourth and final wave of Celtic settlement in Ireland which took place during the first century BC.[1]

The major division within the tribe was between the descendants of Muireadhach's two sons, Indrechtach and Cathal (a quo Clann Cathail), who would both go on to become Kings of Connacht.

Síol Muireadagh's parent dynasty, the Uí Briúin, held the Kingship of Connacht, with one exception, for over 700 years (696–1474). The vast majority of Uí Briúin kings were members of the Síol Muireadaigh, whose power reached its peak in the 12th century when Toirdhealbhach Mór Ua Conchobhair was recognized as High King of Ireland. Toirdhealbhach's son Ruaidri mac Tairrdelbach Ua Conchobair, would go on to succeed him, becoming last the Gaelic High King of Ireland.
