He held the title of the Jurat de l'Estament Militar de Xàtiva in 1395, 1406 and 1407 respectively, a title that had been held by many previous generations of this branch of the Borja family based on Ventres street in Xàtiva.
This same branch, of which Rodrigo Gil was the Head of House, would later go on to become the Borgia family in Italy.
[1] The birth date of Rodrigo Gil de Borja y Fennolet is unknown, although he is known to have lived in Xàtiva.
He was the only son of Rodrigo de Borja and his first wife Sabina Anglesola, though he also lived with his stepmother whose last name he inherited, Francesca de Fenollet (d. 1375), apparently after the death of his mother.
His paternal ancestor, Rodrigo de Borja, the presumed founder of their house, participated in the Conquest of Orihuela in 1272.
