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.
Louis Philippe I
Many remaining French monarchists regard the descendants of Louis Philippe's grandson, who hold the title "Count of Paris", as the rightful pretenders to the French throne; others, the Legitimists, consider Don Luis-Alfonso de Borbón, Duke of Anjou (to his supporters, "Louis XX") to be the rightful heir. Head of the Royal House of Bourbon, Louis is descended in the male line from Philippe, Duke of Anjou, the second grandson of the Sun-King, Louis XIV. Philippe (King Philip V of Spain), however, had renounced his rights to the throne of France to prevent the much-feared union of France and Spain.
