Louis Alphonse, Duke of Anjou
Their father has conferred upon them the historic French titles of, respectively, Duke of Burgundy ("duc de Bourgogne"), and Duke of Berry ("duc de Berry"). (In Spain, the twins are "Don" Luis and "Don" Alfonso de Borbón Vargas). Prince Louis, as Legitimist Dauphin of France, is expected to succeed his father as head of the French royal house, the senior Bourbon/Capetian line, in Legitimist reckoning. However, under Spanish law, and assuming Felipe VI does not in future father a son, the Spanish crown will be inherited by his elder daughter Leonor, Princess of Asturias, who will become queen regnant, and if Felipe does have a son, that son will inherit the Spanish throne regardless of the genealogical seniority of the Anjou branch. Louis and Alphonse were baptised on 5 September 2010 at St Peter's Basilica in Vatican City. Louis' godparents were Arancha Martínez-Bordíu and Francisco D'Agostino and Alphonse's were Amparo Corell de Trenor, and Lorenzo Perales.
Prince Xavier of Bourbon-Parma
Son of a deposed ruler, he had relatives – associated with France, Spain and Portugal's monarchical regimes – engaged in legitimist politics, although others – in Luxembourg, Belgium, Denmark and Italy – were affiliated with dynasties reigning in liberal-democratic frameworks. His views on contemporary French politics are not clear from known records. He upheld the legitimist claim of the Spanish Bourbons to the crown of France. On the other hand, the head of the family, Élie, openly abandoned the legitimist cause, acknowledging Alfonso XIII as the legitimate king of Spain Then Traditionalist author Francisco Melgar asserts that Prince Xavier remained within ""más pura doctrina tradicionalista"", demonstrating ""adhesion profunda"" to legitimist claimants, while others suggest that he nurtured democratic ideas.
