Prince Jean of Orléans, Duke of Guise (Jean Pierre Clément Marie; 4 September 1874 – 25 August 1940), was the third son and youngest child of Prince Robert, Duke of Chartres (1840–1910), grandson of Prince Ferdinand Philippe and great-grandson of Louis Philippe I, King of the French. His mother was Françoise of Orléans, daughter of François, Prince of Joinville, and Princess Francisca of Brazil. He was the Orléanist claimant to the throne of France as Jean III. Biography In 1926 at the death of his cousin and brother-in-law Philippe, Duke of Orléans, claimant to the defunct throne of France as "Philip VIII", Jean was recognised by his Orléanist supporters as titular king of France with the name "Jean III". The claim was disputed by supporters of the Infante Jaime, Duke of Madrid, Legitimist claimant to the defunct French throne. Jean was an amateur historian and archeologist, who lived with his family in a large farm near Rabat, Morocco. He and his eldest son were legally forbidden from ever entering France, due to an 1886 edict which condemned the heads of Bourbon & Bonaparte dynasties, as well as their heirs apparent, to exile. Jean died in Larache, Morocco, in 1940. He was succeeded as Orléanist claimant to the defunct French throne by his only son, Henri d' Orléans, Count of Paris. Marriage and issue In 1899, Jean 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.
