Gaston, Duke of Orléans
The daughters of Gaston, Duke of Orléans, were the first members of the House of Bourbon since the accession of Henry IV to take their surname from the appanage of their father (d'Orléans). Gaston died without a male heir; his titles reverted to the crown. It was given to his nephew, Philippe I, Duke of Orléans, brother of Louis XIV, whose descendants still bear the surname.
