Isabella of Urgell

Isabella of Urgel (Aragonese: Isabel d'Urchel; died 1071) was Queen of Aragon; the only daughter of Ermengol III, Count of Urgell by his first wife Adelaide of Besalú.^[1][2]

Isabella is mentioned in her brother Ermengol IV's testament.^[3][4]

Isabella married in 1065 King Sancho Ramírez; by this marriage, Isabella was Queen of Aragon.^[5] The couple had one son, Peter I, Sancho's successor who left no surviving children. The couple divorced^[6] in 1070, and both remarried. Isabella may have become the second wife of William I, Count of Cerdanya in 1071.
