The title of Duke of Aumont was established in 1665. It was first given to Antoine d'Aumont de Rochebaron (1601–1669). For a long time, the dukes of Aumont had the title of first Gentleman of the Chamber of the King ("gentilhomme de la chambre du Roi"). They were a fairly influential and wealthy family. They owned the "Hôtel d'Aumont" a large townhouse in Paris. The family also had many other titles including "Marquis of Villequier". This was sometimes used by the heir to the ducal title.
