Note 660 — BOOK IV[649]

Marie Anne Louise Adélaïde Marquise de Coislin (1732-1817), née de Mailly, of the Rubempré and Nesle branch, was the daughter of Louis de Mailly, Comte de Rubempré and cousin to the four Mesdemoiselles de Mailly, daughters of the Marquis de Nesle—the Comtesse de Mailly, the Comtesse de Vintimille, the Duchesse de Lauraguais, and the Marquise de La Tournelle, afterwards Duchesse de Châteauroux—who successively became mistresses to Louis XV. She married first, in 1750, Charles Georges René de Cambout, Marquis de Coislin, who died in 1771, leaving no children living. More than twenty years later, in 1793, the Marquise de Coislin, then over sixty, married one of her cousins, twelve years younger than herself, Louis Marie Duc de Mailly, who died and left her a widow for the second time in 1795. There is reason to believe that this marriage was never legally consecrated, as the Duchesse de Mailly continued to be called Marquise de Coislin.—B.
