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