Munio Núñez

Munio's presence is first recorded in 882 in relation to the repopulation and defense of the fortress in Castrogeriz from his base in Amaya.

Munio had to flee in 882 when the Muslim troops led by Al-Mundhir attacked, but by 883, with work on the fortress at a more advanced stage, he was able to resist behind the new walls.

[10] In 912, Munio Núñez was one of the three counts that King García entrusted with the repopulation of the land along the banks of the Duero River: Munio repopulated Roa; Gonzalo Fernández brought settlers to Burgos, Clunia and San Esteban de Gormaz; and Gonzalo Téllez settled Osma.

[13][a] Historian Manuel Carriedo Tejedo hypothesizes that King García's wife could be the daughter of Nuño Ordóñez, brother of King Alfonso III of Asturias, and that Muniadona could also be the mother of Count Fernán González of Castile.

[15] Justo Pérez de Urbel also suspected that Fernán González was related, through his mother, to King Alfonso III.
