Information
Sancia of Naples is the illegitimate daughter of King Ferrante of Naples and the sister of Alfonso of Naples. When a marriage to the Borgias was proposed, Juan Borgia refused to marry her due to her illegitimacy. She was married instead to Joffre Borgia, but Juan became struck by her beauty and began an affair with her.

Historical notes

 * Alfonso of Naples was in fact father to Sancia, not her brother as the series suggests. Her brother was Alfonso of Aragon, second husband to Lucrezia Borgia.
