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.
Madame Royale
It was similar to the style "Monsieur", which was typically used by the King's second son. Just as Gaston, duc d'Orléans (1608–1660), the second son of King Henry IV of France (1553–1610), was known as " Monsieur", Elisabeth of Bourbon (1602–1644), the eldest daughter of Henry, was known before her marriage to King Philip IV of Spain (1605–1665) as "Madame Royale". After her death, the title was borne by her younger sister, Christine Marie of France (1606–1663), until her marriage to Victor Amadeus I, Duke of Savoy (1587–1637).
The most famous holder of this honorific was King Louis XVI of France's eldest daughter, Marie-Thérèse-Charlotte (1778–1851), the only one of his immediate family to survive the French Revolution. She later married her cousin, Louis-Antoine, duc d'Angoulême (1775–1844), and played a prominent role during the Bourbon Restoration.
