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.
Line of succession to the French throne (Orléanist)
Alfred de Gramont alleged in his diary, ""L'ami du Prince": Journal of a Novel", published by Eric Mension Rigau-Fayard in 2011 that this decision was made by the Orléans for two reasons: first, the desire of other dynasts to exclude the Comte d'Eu and the princes of Orléans-Braganza (who were the heirs presumptive to the Empire of Brazil, and after abolition of the monarchy in 1889, pretenders thereto), and second, the influence of French nationalism. However, exclusion from the French succession as a consequence of permanent emigration to Brazil had been acknowledged and accepted in writing by the Comte d'Eu prior to his marriage to the Princess Imperial of Brazil.
