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.
Louise Élisabeth of France
Marie Louise Élisabeth of France (Marie Louise Élisabeth; 14 August 1727 – 6 December 1759) was a French princess, the eldest daughter of King Louis XV of France and his Queen consort, Maria Leszczyńska, and the elder twin of Anne Henriette de France. She married Infante Philip, younger son of Philip V of Spain, who inherited the Duchy of Parma from his mother in 1748, thereby founding the House of Bourbon-Parma. In secondary sources she is referred to also as "Louise Élisabeth of France". She functioned as the de facto ruler of the Duchy of Parma between 1748 and 1759.
