Delbhna - south County Roscommon, and both sides of the Corrib
The Delbhna Nuadat were lords of a large section of what is now Athlone in County Roscommon, situated between the Suca and Shannon rivers.
The royal dynasty of the Delbhna Tir Dha Locha adopted the surname MacConraoi, sometimes anglicised as Conroy, still found in Connemara and other parts of County Galway, but more often as King.
