In 1148 Manrique Pérez de Lara and his relatives gave some houses in Toledo to Gonzalo, allowing him to expand his interests into the largest and most prosperous city in the kingdom.
[3] He was thus in charge of the royal military entourage, an office usually reserved for young noblemen, although he held it again under Alfonso VIII from November 1171 until his death.
His widow, Mayor, was still living in January 1182 when she, jointly with her children who confirm the charter, founded a Cistercian convent in the village of Aza.
The children, as recorded in this charter, were Fernando, Pedro, Alberico, Nuño, Domicio, and Inés, who entered the nunnery on that date.
[4] The properties donated for the foundation of the convent, attached to the Monastery of Bujedo de Juarros, were situated in Aza, Torregalindo, Zorita, Hontangas, Sepúlveda, Camareno, and other places.
