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.
Louise Henriette de Bourbon
Among her extramarital affairs, she is said to have had a relationship with the Count of Melfort whom she met at the Château de Saint-Cloud after the birth of her son. During the Revolution of 1789, Philippe-Égalité publicly claimed that his real father was not his mother's husband at all but instead a coachman at the Palais-Royal.. This assertion was likely for political reasons to distance the ambitious Duke from the ancien regime. However recent DNA testing, to establish the Y-chromosome haplogroup and STR pattern of the House of Bourbon, has indeed confirmed the biological legitimacy of Louise Henriette's eldest son, Philippe-Égalité. As part of this project samples were taken from 3 living genealogical descendants of Louis XIII, namely Axel, Prince of Bourbon-Parma; Henri, Prince of Bourbon-Parma, and João Henrique, Prince of Orléans-Braganza. The former 2 are documented male line descendants of Philip V of Spain, who was a grandson of Louis XIV. The latter is a direct male line descendant of Philip I, Duke of Orleans - a younger brother of Louis XIV and the ancestor of Louise Henriette's husband. This study established that no non-paternity event happened along the three studied in-depth paternal lineages of these living donors, thus discounting rumors that the branch of Bourbon-Orleans could be illegitimate.
