He governed the lordships of Hita and Guadalajara, and frequently attended the royal court under King Alfonso VI and Queen Urraca.
The Muslim historian Ibn Abi Zar recorded that a "son of Count García" (Iben al-Zand Garsís) held the towns of Guadalajara and Hita.
[1][2][4] In twelfth-century León and Castile, it was uncommon for the lords of the southern frontier—whose primary responsibility was defence against the Almoravids—to frequently attend the itinerant royal court.
Earlier that year, in April or May, Queen Urraca had granted those lands at Uceda and some others at Hita to the betrothed or recently married couple.
Fernando disregarded this royal charter, placing greater stock in aristocratic custom based on Visigothic law, by which he acquired one half of all his wife's acquisitions during their marriage.
Urraca, probably conceived shortly after their marriage, was betrothed to Count Rodrigo Martínez, who granted her a bridewealth on 29 November 1129, when she was probably only ten years old.
Stephanie, ten years a widow and still young, married Count Rodrigo González de Lara in 1135.
