Prince Jean, Duke of Guise king of France as "Jean III". The title was disputed by members of the Spanish Anjou branch of the family, descended from Louis XIV of France. He died in Larache, Morocco, in 1940. He was succeeded as claimant to the French throne by his only son, Henri d' Orléans, Count of Paris. In 1899, he married his first cousin, Isabelle d'Orléans (1878–1961). She was the younger sister of Philip VIII, and the daughter of Philip VII and Marie Isabelle d'Orléans. They had four children: Prince Jean, Duke of Guise Prince Jean of Orléans, Duke of Guise (Jean Pierre Clément Marie;
Prince William Henry, Duke of Gloucester and Edinburgh Yorkshire). Her mother was the Duke's mistress Lady Almeria Carpenter, a daughter of the first Earl of Tyrconnell. Louisa was married on 29 December 1803 in Norwich, Norfolk to Godfrey Macdonald, 11th Baronet Macdonald of Slate, later the 3rd Baron Macdonald of Slate. They had three children born before their marriage (legitimized by Scottish law, but not by Irish law) and ten children born after their marriage. (A previous marriage in Scotland was considered of doubtful validity.) These children and their posterity are the only descendants of Prince William, 1st Duke of Gloucester and Edinburgh. The Duke died at Gloucester
