Charles-Philippe d'Orléans was the last child and only son of
Emmanuel d'Orléans (1872-1931),
Duke of Vendôme, and his wife
Princess Henriette of Belgium (1870-1948), Duchess of Saxony. Through his mother, daughter of
Prince Philippe of Belgium (1837-1905),
Count of Flanders, he is affiliated to the Belgian dynasty of
Saxe-Coburg and Gotha: Charles-Philippe is the great-grandson of
King Leopold I and the nephew of
Albert I of Belgium. On his father's side, the prince belongs to the youngest line of the
House of Orléans, descended from the Duke of Nemours, considered by the Orleanists to be the branch of the princes of the blood, heir to the eldest branch in the event of extinction, according to French monarchical traditions. On 24 September 1928, Prince Charles-Philippe d'Orléans married Marguerite Watson (1899-1993), an American whom he had met during a trip to the
United States; from their union, which was not recognized by the Duc de Guise (then the Orleanist pretender to the throne of France and head of the family), no children were born. == Biography ==
