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.
House of France
Since 1733, all legitimate male Capetians were of the House of Bourbon, of the Vendôme branch, descended from Charles, Duke of Vendôme. The descendants of Charles (themselves from the Dukes of Bourbon and, by them, from the youngest son of St. Louis), then became the only surviving legitimate branch of the Capetian dynasty. The House of Bourbon-Busset form, indeed, the elder branch, but are not considered dynasts of the House of Bourbon (for they descend through what is considered an illegitimate line). These are the only surviving Bourbons who are not descended in male line from Henry IV. Charles' eldest son Antoine, King of Navarre, was the ancestor of the royal dynasties of France and Spain, and of the House of Orléans, while his youngest son Louis, Prince of Condé (1530–1569), was the ancestor of the House of Condé. A cadet branch of the Condés was the House of Conti, who in male line descended of Henri, Prince of Condé (1588–1646). Both Condés and Contis were ranked as Prince du sang.
