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.
Prince of Guéméné
The present male line descendants live in Austria, the family having fled France due to the French Revolution.
The present Prince of Guéméné is also a claimant to the Duchy of Bouillon. In 1816, at the Congress of Vienna, it was decided that the family were the rightful heirs to the duchy which had been the property of the House of La Tour d'Auvergne. Through the marriage of Jules and Marie Louise de La Tour d'Auvergne in 1743, the Princes of Guéméné were descendants of the La Tour d'Auvergne family through Marie Louise, whose nephew Jacques de La Tour d'Auvergne (son of her brother the Duke of Bouillon and Mademoiselle de Marsan) was the last Duke of Bouillon.
