Happy Birthday to Princess Diana, Duchess of Cadaval and Anjou, who turns 40 today! The third daughter of Dom Jaime Álvares Pereira de Melo, 10th Duke of Cadaval, she succeeded to the title because her parents had a religious wedding as opposed to the civil wedding of the mother of her elder half-sisters. In 2008, the she married Prince Charles-Philippe of Orléans, Duke of Anjou, a nephew of the Orleanist Pretender to the Former French Throne. The couple have one daughter, Princess Isabelle d’Orléans. The Duchess studied international communication at the American University of Paris and has written a plethora of books on Portuguese History. She also manages the Palace of the Dukes of Cadaval in Évora, and the Muge estate in Santarém. I wish HRH a very Happy Birthday and Many Happy Returns!
