Duchesse D'Aiguillon
Marie Madeleine de Vignerot du Pont de Courlay, Duchesse d'Aiguillon (1604 – 17 April 1675) was the daughter of Cardinal Richelieu's sister, Françoise du Plessis and her husband René Vignerot.
In 1620 she married a nephew of the constable de Luynes, Antoine de Beauvoir du Roure, sieur de Combalet, who died in 1622. In 1625, through her uncle's influence, she was made a lady-in-waiting (dame d'atour) to the queen-mother Marie de' Medici, and in 1638 was created duchess of Aiguillon.
She did not marry a second time, although Richelieu wished to marry her to a prince, either to the comte de Soissons or to the king's brother.
