Anne-Madeleine de Conty d'Argencourt
Anne-Madeleine de Conty d'Argencourt (1637–1718), known at court as Mademoiselle de la Motte-Argencourt, was a French noblewoman and a prominent figure at the royal court. She was born in Montpellier to Pierre de Conty d'Argencourt, a military engineer, and Madeleine de Chaumont de Bertichères. Her mother died around 1638, and Anne-Madeleine was baptized in 1641.
She became a maid of honour to Anne of Austria, the queen mother, in 1657. In 1658 she is said to have been the mistress of Louis XIV, and she appears in memoirs as part of royal intrigues. She later became the mistress of Jean-Baptiste Amador de Vignerot du Plessis, marquis of Richelieu, which angered the king. After this, she briefly retired to the convent of the Filles de Sainte Marie de Chaillot, though she did not remain a nun and eventually left to marry.
On 4 August 1671 she married Gabriel de Grasset, seigneur de Farlet, a Montpellier councillor. In 1679 she fled France for Flanders with Olympia Mancini after being implicated in the Affair of the Poisons. She died in 1718, and in her will she left her Montpellier house to the Dames de la Miséricorde to help care for the sick.
There is sometimes confusion with Anne-Lucie de la Mothe-Houdancourt due to similar names, but they were different people.
