Anne Louise de Noailles was executed by guillotine in Paris on July 22, 1794, during the Reign of Terror. She was thirty-five and had remained in France while her husband, Louis Marie de Noailles, was abroad. Her final period was one of imprisonment and revolutionary prosecution, rather than a documented terminal disease. She was held with her mother, Henriette d'Aguesseau, and grandmother, Catherine de Cossé-Brissac, and all three were put to death on the same day. Their shared fate is central to the account, but the women were distinct people and the details of one should not be silently transferred to another. Their remains were buried among the victims at Picpus. The family connection also explains the presence of these losses in the story of her sister Adrienne de Lafayette, who survived the Revolution. The available biography supports the imprisonment, execution date, method, and family group; it does not securely establish every exchange in prison, the exact words spoken at the scaffold, or a continuous hour-by-hour account. Those private scenes remain uncertain.
