Duke of Châtellerault
The duchies of Châtellerault and Bourbon were then conferred on Louise of Savoy , the mother of King Francis I , but the latter title became extinct in 1530 when she ceded the territory of the duchy to Louis de Bourbon , Prince de la Roche-sur-Yon and later also Duc de Montpensier .
