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.
Capetian dynasty
Many years have passed since the Capetian monarchs ruled a large part of Europe; however, they still remain as kings, as well as other titles. Currently two Capetian monarchs still rule in Spain and Luxembourg. In addition, seven pretenders represent exiled dynastic monarchies in Brazil, France, Spain, Portugal, Parma and Two Sicilies. The current legitimate, senior family member is Louis-Alphonse de Bourbon, known by his supporters as Duke of Anjou, who also holds the Legitimist ("Blancs d'Espagne") claim to the French throne. Overall, dozens of branches of the Capetian dynasty still exist throughout Europe.
