Jeanne de Valois-Saint-Rémy

Jeanne de Valois-Saint-Rémy (22 July 1756 – 23 August 1791) was a known French thief. She was married to Nicholas de la Motte whose family's claim to nobility is dubious. 
She herself was a descendant of the Valois royal family through an illegitimate son of King Henry II. She is known for her role in the Affair of the Diamond Necklace, one of many scandals that led to the French Revolution and helped to destroy the monarchy of France.
