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.
Prince Charles Philippe, Duke of Anjou
The House of Orléans never possessed or used the Anjou ducal title during the "ancien régime", but its head claims the right "de jure" to dispose of it, as of all titles traditional in France's royal house. So, too does the Legitimist claimant. Thus, Charles-Philippe, Duke of Anjou and Louis Alphonse, Duke of Anjou are contemporaries and cousins — both reared in Spain, as it happens — but nominally represent different and competing rationales for restoration of the French monarchy.
