¿Quién se casó con Francisco de Paula de Borbón y Castellví?

Francisco de Paula de Borbón y Castellví (Spanish: Don Francisco de Paula Maria Trinidad Enrique Gabriel Miguel Rafael Edmundo Buenaventura de Borbón y Castellví; 29 March 1853 – 28 March 1942) was a Spanish nobleman and military officer. He was a younger son of the controversial Infante Enrique of Spain, who was a grandson of Charles IV of Spain and younger brother of Francis, Duke of Cádiz, king consort of Isabella II of Spain. Despite his family ties, Francisco never had the title of Infante of Spain because his parents' marriage was unequal and did not receive approval from Queen Isabella II. That is also the reason why he was not recognised as a Carlist pretender.
