likewise went their separate ways following Alfonso's death, the former passing to his brother, the latter to a descendant of its original ruling family, with each eventually passing to other dynasties through heiresses: Petronilla of Aragon, who married the ruler of Barcelona and thus united those two realms into the Crown of Aragon; and Blanca, sister of Sancho VII of Navarre, whose 1234 death brought Jiménez rule to an end. The Borgias of Italy in the 15th century would present a pedigree that traced their ancestry to Pedro de Atarés, lord of Borja, Zaragoza, who had been a competitor for the thrones of Navarre and Aragon following the death of Alfonso the Battler. Pedro was a scion of this family, being grandson of Sancho Ramírez, Count of Ribagorza, illegitimate brother of king Sancho Ramírez of Aragon. Such a descent would thus have made the Borgias male-line descendants of the Jiménez dynasty. However, the descent was a fabrication. Rulers Emperors in bold.
