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 Marie Adélaïde de Bourbon, Duchess of Orléans
Louise Marie Adélaïde de Bourbon-Penthièvre, Duchess of Orléans (13 March 1753 – 23 June 1821), was the daughter of Louis Jean Marie de Bourbon, Duke of Penthièvre and of Princess Maria Theresa Felicitas of Modena. At the death of her brother, Louis Alexandre de Bourbon-Penthièvre, "prince de Lamballe", she became the wealthiest heiress in France prior to the French Revolution. She married Louis Philippe II, Duke of Orléans, the "regicide" "Philippe Égalité", and was the mother of France's last king, Louis Philippe I, King of the French. She was sister-in-law to "the princesse de Lamballe", and was the last member of the "Bourbon-Penthièvre" family.
