The name of Íñigo's mother is unknown (she is sometimes called Onneca, without foundation) but it is known that she also married local muwallad lord Musa ibn Fortun al-Qasawi, by him having a son Musa ibn Musa al-Qasawi. This younger Musa would become head of the Banu Qasi, ruler of Tudela and one of the chief lords of Ebro Valley. Due to this relationship, Íñigo and his kin frequently acted in alliance with Musa ibn Musa, a relationship that allowed Íñigo to extend his influence over large territories in the Pyrenean valleys, and was also instrumental in the rebellions that would lead to Pamplona breaking with the Emirate.
