The Iron Age mountaintop fortress Caherconree, preserving the name of the legendary Cú Roí, a cousin of Conaire Mór, is found on the Dingle Peninsula, the name of which in Modern Irish is Corca Dhuibhne.
A descent from the Corcu Duibne would make the O'Connells of Derrynane kin to the O'Sheas and O'Falveys, and descendants of the legendary Conaire Mór, ancestor also of the Dál Riata monarchs of Scotland.
