 The only child positively assigned to her by Cennétig - who had a number of wives - was High King of Ireland, Brian Boru (c. 941–23 April 1014).This makes Bé Binn ancestor to all subsequent Dál gCais O'Briens and their offshoots.After the death of Cennétig, she appears to have been remarried to a king of the Corco Modhruadh (Corcomroe), a region in north-west County Clare.
