Pedro González de Lara

[5] Count Raymond IV of Toulouse, possibly in 1092, completed a marriage alliance with Alfonso VI by marrying his illegitimate daughter, Elvira.

[6] Among these Spaniards was probably to be found Pedro González, who disappears from the records of the kingdom of Castile–León at precisely this time, and does not reappear until 22 September 1105 at Burgos.

At the behest of Alfonso VI, in 1105 Pope Paschal II gave the second of three orders (the others coming in 1100 and 1109) commanding Spaniards who had gone to the Holy Land to return to their kingdom.

[5][7] There is no contemporary evidence for Spanish participation in the First Crusade, but the late thirteenth-century Gran conquista de Ultramar refers to "a company of Spanish knights there had been" at the Siege of Nicaea in 1097, "guarding the count of Toulouse, whose chief he had nominated, Lord Pedro González the Roamer, who was a very good knight in arms, and was born in Castile.

"[8] It goes on to narrate an event which supposedly took place during the Siege of Antioch (1097–98) after the horse of Robert II, Count of Flanders, was killed beneath him and he was forced to fight dismounted against a number of Turks.

Two knights, one from France and the other Pedro González, came to his rescue, "but the Spaniard, who arrived first, gave such a great blow to the back of a Moor with the lance he carried in his hand that it came out his chest a cubit, and he left him dead on the ground.

Urraca bore Pedro two children: a daughter, Elvira, and a son, Fernando Pérez Furtado, so-called because he was deprived of an inheritance as a bastard.

[10] Sometime before November 1127 Pedro González married the countess Eva (Ava), the young widow of count García Ordóñez, who had ruled Nájera and been killed in the Battle of Uclés.

Though traditional genealogies portray her was daughter of Pedro Fróilaz de Traba, her non-Iberian name and that given her eldest son have led this to be rejected in favor of a French origin, perhaps as daughter of Almanric (Aymeric V), viscount of Rochechouart and one of the French barons who had answered Alfonso VI's international call for aid against the Almoravids following the Battle of Sagrajas (1086).

With his wife, Pedro had several children, including four sons: Manrique, Nuño, Álvaro, and Rodrigo, and daughters Milia and Maria.

[11] Sometime before 1165 Rodrigo became the prior of the Cluniac foundation of San Salvador de Nogal and is the only known male member of the Castilian aristocracy to take holy orders in the twelfth century.

[12] On 2 September 1125 Pedro gave his vills of Uranave and Ranedo to Santo Domingo de Silos in exchange for the monastery's properties at Arlanza and Tordueles.
