Today, the primogenitural heir to the Dauphinate of Auvergne (Montpensier) would be The Dowager Archduchess of Austria-Este. The primogenitural heir to the Duchy of Auvergne (Bourbon and the original dauphinate) would be The Dowager Duchess of Calabria . Each of the three noblemen also happen to be pretenders of much larger former monarchies, too.
