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 Croÿ
Another son, Auguste de Croÿ, 9th Duke of Croÿ, better known as "Le Bel Auguste" (1765–1822), was mediatized upon the demise of the Holy Roman Empire in his capacity as sovereign prince of Dülmen. When the Bourbons were restored to the throne of France, Auguste was made a peer of France. From three of Auguste's sons - Alfred, Ferdinand and Philipp Franz - descend the three extant branches of the House of Croÿ, residing in Germany and France. 
On 27 October 1913, Karl Rudolf, 13th Duke of Croÿ, married Nancy Leishman, daughter of Pittsburgh industrialist John George Alexander Leishman, United States Ambassador to Germany and former president of Carnegie Steel. In 1974 Karl Rudolf died and was succeeded by his son Carl (d. 14 June 2011), 14th Duke of Croÿ; Carl was married to Princess Gabriele, daughter of Crown Prince Rupprecht of Bavaria. Their eldest son, Rudolf, the 15th and current Duke of Croÿ, married Alexandra Miloradovich; they had six children. Duchess Alexandra died on September 23, 2015; her funeral took place at St Jakobus Kirche in Dülmen on October 3, 2015. The Duke and his family live at their "Haus Merfeld" estate near Dülmen.
