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)
Becoming the Head of the House of Orléans on his father's death in 1999, the new Count of Paris and "Duke of France" cancelled the dynastic exclusions imposed by his father. Acknowledging that no one has the power to change the order in succession of a prince of the blood royal of France, he recognised his brother, Prince Michel, Count of Evreux and his male-line descendants, and Robert, Count of La Marche, son of his deceased brother Prince Thibaut, Count of La Marche, as possessing succession rights to the French crown, should it ever be restored.
