Antoine de Vignerot du Plessis

Louis Antoine Sophie de Vignerot du Plessis (4 February 1736 – 1791), Duke of Fronsac, then Duke of Richelieu (1788), Prince de Mortagne, Marquis du Pont-Courlay, Comte de Cosnac, Baron de Barbezieux, Baron de Coze and Baron de Saugeon, was a French nobleman and general.

Life

He was the son of Louis François Armand de Vignerot du Plessis (1696–1788), Duc de Richelieu, Marshal of France and an expert courtier, and of Marie Élisabeth Sophie de Lorraine (daughter of Anne Marie Joseph de Lorraine. Madame de Pompadour wished Louis to marry her daughter but his father avoided that demand by pretending that Louis's mother was Princess of Lorraine (much superior to the house of Richelieu) and that he would thus need the permission of the head of that house (Francis I) for the marriage. Madame de Pompadour did not press her claims any further.

A first cousin was Marie Charlotte, Princess of Beauvau, wife of Charles Juste de Beauvau and daughter of the Duke of Bouillon.

He succeeded his father as a premier gentilhomme de la chambre to King Louis XVI, and later became a maréchal de camp and lieutenant général (1780).

Marriage and issue

His first marriage, on 25 February 1764, was to Adélaïde de Hautefort. They had one child, Armand Emmanuel (1766–1822).

His second marriage, on 20 April 1776, was to Marie-Antoinette de Galliffet. They had two children :

• Armande Marie (born 1777) (Marquise de Montcalm-Gozon) ;
• Armande Simplicie Gabrielle (born 1778) (Marquise de Jumilhac)
