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.
Henri, Count of Chambord
In November 1846, the "comte de Chambord" married his second cousin Archduchess Maria Theresa of Austria-Este, daughter of Duke Francis IV of Modena and Princess Maria Beatrice of Savoy. The couple had no children.
In the early 1870s, as the Second Empire collapsed following its defeat in the Franco-Prussian War at the battle of Sedan on 1 September 1870, the royalists became a majority in the National Assembly. The Orléanists agreed to support the aging "comte de Chambord"'s claim to the throne, with the expectation that at his childless death he would be succeeded by their own claimant, Philippe d'Orléans, comte de Paris. Henri was then pretender for both Legitimists and Orléanists, and the restoration of monarchy in France seemed a close possibility. However, Henri insisted that he would accept the crown only on condition that France abandon its tricolour flag and return to the use of the white "fleur de lys" flag. He rejected a compromise, whereby the "fleur-de-lys" would be the new king's personal standard, and the tricolour would remain the national flag.
