Eóganacht Locha Léin

Eóganacht Locha Léin or Uí Cairpre Luachra were a branch of the ruling Eóganachta of Munster.

Cairbre of Sliobh Luachra was on the Cork-Kerry border; Eóganacht Locha Léin is around the Lakes of Killarney.

Cairpre Luachra was a sixth generation descendant of Éogan Mór, ancestor of the Eoganachta.

Máel Dúin mac Áedo broke the monopolisation of the Cashel kingship by the Aurmumu septs.

The West Munster Synod, which was written in the late eighth century, or early ninth, demonstrates attempts by the Ciarraige to check Locha Léin power.
