The Cronica de Sampiro, as reproduced in the Historia Silense, records the alliance between King Alfonso and "Galiam simul cum Pampiloniam, causa cognacionis", adding that he had married “uxorem ex illorum prosapia...Xemenam consubrinam Caroli regis”. The Cronica de Sampiro (interpolated, España Sagrada edition) records that “Adefonsus filius Domini Ordonii” married “Pampilona…uxorem ex illorum prosapia generis…Xemena” by whom he had “filios...Garseanum, Ordonium, Froilanum et Gundisalvum qui archidiaconus ecclesie Ovetensis fuit”. Sánchez-Albornoz suggests that she was the daughter of King García I, but she is not included among his children listed in the Codex de Roda. Settipani, while agreeing that Jimena must belong to the royal family of Navarre, highlights difficulties with this theory while recognising that none of the other possible origins appears viable. The most obvious difficulty is chronological, as Jimena´s marriage date suggests that, if she was related to the early kings of Navarre, she probably belonged to the subsequent generation. The reference in the Cronica de Sampiro, as reproduced in the Historia Silense, to the alliance between King Alfonso and "Galiam simul cum Pampiloniam, causa cognacionis" suggests an alternative possibility that Jimena may have been related to the dukes of Gascony, who maintained close relations with the kings of Pamplona as indicated by charter evidence.
The Cronica de Sampiro (interpolated, España Sagrada edition) records that “uxore sua Xemena regina” was buried with her husband “Astoricæ” but that their bodies were transferred to “Oueto...sub aula sancte Marie Dey genitricis”.The Chronicon Regum Legionensium names "Queen Jimena" as the wife of "King Alfonso", when reporting their reburial in light of the threatened invasion of the kingdom of León and Asturias by Al-Mansur. 1
