Louis Alphonse, Duke of Anjou
Louis Alphonse was born in Madrid, the second son of Alfonso de Borbón, Duke of Anjou and Cádiz, and of his wife María del Carmen Martínez-Bordiú y Franco, eldest granddaughter of Francisco Franco. Alfonso was at that time the dauphin (using "Duke of Bourbon" as title of pretence) according to those who supported the claim of his father, Infante Jaime, Duke of Segovia to the French throne. On 20 March 1975, the Infante Jaime ("Henri VI" by Legitimist reckoning) died. Alfonso then asserted his claim to be both Head of the House of Bourbon and Legitimist claimant to the throne of France and the Co-Principality of Andorra. As such, he took the title "Duke of Anjou", and on 19 September 1981 gave Louis Alphonse the title Duke of Touraine.
Louis XIII of France
Born at the Château de Fontainebleau, Louis XIII was the oldest child of King Henry IV of France and his second wife Marie de' Medici. As son of the king, he was a Fils de France ("son of France"), and as the eldest son, Dauphin of France. His father Henry IV was the first French king of the House of Bourbon, having succeeded his ninth cousin, Henry III of France (1574–1589), in application of Salic law. Louis XIII's paternal grandparents were Antoine de Bourbon, duc de Vendôme, and Jeanne d'Albret, Queen of Navarre. His maternal grandparents were Francesco I de' Medici, Grand Duke of Tuscany, and Joanna of Austria, Grand Duchess of Tuscany. Eleonora de' Medici, his maternal aunt, was his godmother. As a child, he was raised under the supervision of the royal governess Françoise de Montglat.
