Page "Duchy of Montpensier" Paragraph 5

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.

The title subsequently remained in the Orléans family, and was borne in particular by Antoine Philippe ( 1775 – 1807 ), son of Philippe Egalité, and by Antoine Marie Philippe Louis ( 1824 – 1890 ), son of King Louis-Philippe and father-in-law of King Alphonso XII of Spain.

Mademoiselle de Montpensier was a title conferred upon some women of the royal family, namely during the years previous to the French Revolution.
