After their deaths without issue, their younger sister Marie brought the countship to her third husband, John I, Duke of Bourbon (1381–1434).
Confiscated by King Francis I, the countship was restored in 1538 to Louise de Bourbon, sister of the Constable of France, and widow of the prince de La Roche-sur-Yon, and to her son Louis, and was erected into a duchy in the peerage of France (duché-pairie) in 1539.
Marie, daughter and heiress of Henry, Duke of Montpensier, brought the duchy to her husband Gaston, Duke of Orléans, brother of Louis XIII, whom she married in 1626, and their daughter and heiress, known as La Grande Mademoiselle was duchess of Montpensier.
When Mademoiselle Anne died childless, her heir (but an ancestress' Huguenot marriage after being a nun may have been regarded invalid) was Elisabeth Charlotte, Princess Palatine, the then wife of Duke of Orléans.
Mademoiselle de Montpensier was a title conferred upon some women of the royal family, namely during the years previous to the French Revolution.
