Sancho III of Navarre
Another hypothesis on the filiation of Gonzalo Núñez de Lara is proposed by Margarita Torres who suggests that Gonzalo would be the son of a Munio González, son of Gonzalo García who, in turn, was the son of count García Fernández of Castile. Munio González, probably the count in Álava in the year 1030 was the brother of Salvador González, tenente in La Bureba, and this would explain the relationship between the Lara and the Salvadórez. Both brothers were vassals of king Sancho III of Navarre and Munio appears often in charters with his nephews Gonzalo and Álvaro Salvadórez.
