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 Monpezat
The House of Monpezat (or Laborde de Monpezat; ) is a French noble family associated with the Danish Royal Family by marriage after 1967, when Henri de Laborde de Monpezat wed Princess Margrethe of Denmark, heir presumptive of the ruling House of Glücksburg. In the event of ascension to the Danish throne of their son or male-line descendant, the main branch of the Danish Royal Family will belong patrilineally to the "Laborde de Monpezat" lineage. However, it is unclear which name the royal family will use in this event.
