Sancho Garcés III de Pamplona
Sancho was a son of William II Sánchez and Urraca of Navarre and relative of Sancho III of Navarre and he spent a portion of his life at the court of that king in Pamplona. He also took part in the Reconquista. It is possible he even submitted Gascony to the suzerainty of Navarre. In 1010, he appeared together with Sancho, Robert II of France, and William V of Aquitaine at Saint-Jean d'Angély. He certainly never paid homage to the king of France.
