 Marie-Louise-Sophie de Grouchy, Marquise de Condorcet was born in 1764 at the Chateau de Meulan. She died in 1822 of an unknown disease. Her parents were Marie Gilberte Henriette Fréteau de Pény and Francois-Jacques, Marquis de Grouchy. She was the eldest of four.  Her sister, Charlotte, married Grouchy’s close friend and collaborator, Pierre-Georges Cabanis. One of her two brothers, Emmanuel de Grouchy, Marshall under Napoleon, was reputedly responsible for the French losing at Waterloo because he chose to finish a dish of strawberries before answering a call to battle.
