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.
Duke of Bourbon
Therefore, the heir male of the Bourbon family belonged to the House of Bourbon-Vendôme from 1527 onwards, in the person of Charles de Bourbon, Duke of Vendôme until he died in 1537. Charles remained loyal to the king, even though Francis I had denied him the Bourbon inheritance and the inheritance of his wife, the sister of Charles IV, Duke of Alençon. Charles's son, Antoine, would become King of Navarre, and his grandson, Henry, would become King of France. All of the present-day family members descend from him. As the new reigning dynasty, the House of Bourbon-Vendôme was simply called the House of Bourbon.
