If Sophie de Grouchy struggled financially during the Terror, and in the years following it, because hers and Condorcet's wealth had been confiscated, she clearly did not stay poor long. In 1805, she purchased her castle for her 15 year old daughter, Eliza.
The castle, Bignon-Mirabeau, is in the Loiret, an hour and a half's drive from Paris with no traffic, but a more substantial journey in a horse-drawn carriage. The castle was named after its previous owner's family: the Marquis de Mirabeau had been born there, and had sold it in 1789, shortly before he died. Owning a castle during the revolution was no easy feat. Its first buyer abandoned it and run away to England. Its second one had it less than ten years.
Two years after she received the castle as a gift, Eliza married an Irish man, the son of a friend of her parents, Arthur O'Connor. The castle stayed in the family, which, over the generation acquired the family name La Tour du Pin. It can be visited today, and among the exhibits, one can see a collection of mementos of Sophie de Grouchy's life, including a self-portrait miniature.
