SANCHO García ([1030/35]-after 29 Nov 1074). "Sancius rex" granted property to "senior Sancio Furtuniones" by charter dated 7 Dec 1057, confirmed by "…Infante domno Santio et uxor eius domna Contanza…"[484]. Señor de Uncastillo y Sangüesa. Salazar y Acha discusses his marriage[485]. The Crónica Najerense records that "infans domnus Sancius, quem rex Garsias Pampilonensium ex concubina habuerat" abducted "filiam regine Stephanie", who was betrothed to "Santius rex", and took her to the court of the Moorish king of Zaragoza and later to Ramiro I King of Aragon, triggering the war between Castille and Aragon during the course of which the Aragonese king was killed in 1064[486]. Sancho IV King of Navarre granted "unas casas en la ciudad de Calahorra" to "germano meo domno Sancio et uxori vestra vel germana mea domna Constanza" by charter dated 29 Nov 1074[487]. m (before 7 Dec 1057) CONSTANZA, daughter of --- & his wife [Stephanie de Foix] (-after 29 Nov 1074). "Sancius rex" granted property to "senior Sancio Furtuniones" by charter dated 7 Dec 1057, confirmed by "…Infante domno Santio et uxor eius domna Contanza…"[488]. Sancho IV King of Navarre granted "unas casas en la ciudad de Calahorra" to "germano meo domno Sancio et uxori vestra vel germana mea domna Constanza" by charter dated 29 Nov 1074[489]. Salazar y Acha hypothesises that Constanza was the daughter of Stephanie de Foix, wife of García V King of Navarre, by an otherwise unrecorded earlier marriage with a noble at the court of Barcelona, suggesting that it would be unusual for King Sancho to refer to his brother´s wife as "germana" unless there was also a blood relationship between them[490]. However, this hypothesis, although appealing, appears unlikely to be correct because Queen Estefania does not include Constanza in her testament dated to [1066] which names all her other known children[491]. Sancho & his first wife had [two] children
