"Garsias Sanctii consul filius regis Sancii" granted "Astaracensem pagum" to "Arnaldo filio meo" by charter dated to [920], signed by "Garciæ Sancii Consulis, Sancii Wilhelmi comitis filii, Salii Vivari, Sancii Amanevi, Gumbaudi, Eneci fratris eius". Jaurgain states that Amanieu Sancho was the fifth son of Sancho Garcia Duke of Gascony, appearing to assume that he was the same person as "Sancii Amanevi" who signed the [920] charter, and that he was ancestor of the Vicomtes de Bezaume and Seigneurs d’Albret. He cites no primary source which confirms the relationship. However, according to his reconstruction, Amauvin [Aimon] (ancestor of the vicomtes de Bezaume) and Amanieu (ancestor of the seigneurs d’Albret) were brothers and were the same persons as "duobus consanguineus nostris Aymone…et Aymonio" who confirmed the charter dated 3 Apr [1009] under which "Bernardus Willelmus comes" confirmed the foundation of Saint-Sever. 2
