Twin Princes for the House of Bourbon

The heir to the French throne, Louis de Bourbon and his wife princess Marie-Marguérite, now have twin boys. Louis and Alphonse were born on Friday May 28, in New York, one minute apart, making Louis second in line to the throne after his father. The young princes Louis and Alphonse will bear the titles duc de Bourgogne and duc de Berry. The couple already had a daughter, princess Eugénie, born in Miami in 2007.

Since the 19th century, two Capetian lines have battled over the right to the throne of France and the title duc d'Anjou: the legitimist branch represented by Louis de Bourbon and the younger Orleanist branch represented by Henri, count of Paris.

The following is from Wikipedia:

Louis Alphonse and Margarita had their first child, a daughter, named Eugenia on 5 March 2007 at Mount Sinai Medical Center, Miami, Miami-Dade County, Florida. She was baptised at the papal nunciature in Paris in June 2007. French legitimists recognise her as Princess Eugenie of Bourbon; in Spanish her name is Doña Eugenia de Borbón y Vargas.

The couple had twin boys, Prince Louis and Prince Alphonse, on 28 May 2010. Louis, as Dauphin, will succeed his father as head of the French Royal House. In Spanish, the boys are Don Luis and Don Alfonso de Borbón y Vargas.

Louis Alphonse of Bourbon is the legitimist pretender to the French crown and could take the name and number Louis XX, if he were reigning and chose to use the name "Louis" as king, and the preceding legitimist pretenders were also assigned regnal names and numbers. He is currently the Head of the House of Bourbon, and claims the following titles:

* Titular Duke of Anjou
* Titular Duke of Touraine
* Titular Duke of Bourbon
* Titular King of France
* Titular King of Navarre
* Head of the House of Bourbon
* Bailiff Grand Cross of Honour and Devotion of the Order of Malta

Note: The articles on Louis de Bourbon and his wife sometimes use French spelling, sometimes Spanish. Eugénie becomes Eugenia, Marie-Marguérite is often written María Margarita, etc... Sometimes even English-language articles refer to him as the duc d'Anjou, instead of duke of Anjou.
