Bé Binn inion Urchadh
Bé Binn inion Urchadh was a Princess of the Uí Briúin Seóla and Queen of Thomond.
Bé Binn was a daughter of King Urchadh mac Murchadh of Maigh Seóla. She was married to King Cennétig mac Lorcáin of Thomond. Cennétig is known to have had as many as eleven sons and at least one daughter, Órlaith íngen Cennétig. The only child positively assigned to her by Cennétig - who had a number of wives - was High King of Ireland, Brian Boru. 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, a region in north-west County Clare. By him she had Lochlann and Conchobar, ancestors of the Ó Lochlainn and Ó Conchubhair Corcomroe.
Her sister Creassa inion Urchadh was a wife of King Tadg mac Cathail of Connacht, while another sister, Caineach inion Urchadh, appears to have married the ancestor of the Clann Coscraig sept of the Uí Briúin Seóla. Her brother, Donnchadh, succeeded their father as king.
