Partraige

The Partraige were a people of early historic Ireland.

Several attested branches were found in Ireland, including the following:

Francis John Byrne has suggested that the Partraige may have been "a remnant of a pre-Celtic population, akin perhaps to the Illyrian tribe commemorated in the Bavarian resort of Garmish-Partenkirchen." He also suggests that the Fir Umaill found in Clew Bay (later the Uí Briúin) probably were a later branch.

They have given their name to the district of Partry.
