House of Orléans
The present head of the house is Prince Henri of Orléans. He is known as the Count of Paris.  He also claims the title King of the French, but is known simply as His Royal Highness The Count of Paris and sometimes the Duke of France. However, the titles are not officially recognised because France is no longer a monarchy. Henri has been a claimant to the throne since 1999. The Count was married to Duchess Marie Thérèse of Württemberg. She is herself a daughter of a one-time claimant to the throne of Württemberg.
