Example Input: Question: What year was Brian named the High King? Passage:The Uí Briúin Seóla was one of the major branches of the powerful Uí Briúin dynasty, which had become the dominant force in Connacht by the 8th century. The genealogies list two sons of Murchadh mac Maenach: Urchadh and Urumhain. Urchadh mac Murchadh, King of Maigh Seóla (also listed as king of Iarthair Connacht, died 945, in the 14th century Book of Ballymote) was father of Bé Binn inion Urchadh, Princess of the Uí Briúin Seóla and Queen of Thomond (fl. early 10th century). Bé Binn married Cennétig mac Lorcáin of Thomond to produce a son who would become the High King of Ireland (Irish: Ard-Rí na hÉireann): Brian Bóruma mac Cennétig, known in English as Brian Boru (c. 941–23 April 1014). Brian broke the near monopoly of the Uí Néill over the High Kingship of Ireland and fought to unite Ireland as a people under one, native king. His father, Cennétig mac Lorcáin of Thomond, was one of the principal leaders of the resistance to the Danish Viking incursions. Cennétig had several wives and children but positively assigned Bé Binn as the mother of Brian Bóruma.
