Louis de Noailles, 4th Duke of Noailles was a French peer and Marshal of France.
Background
He was the son of Françoise Charlotte d"Aubigné, niece of Madame de Maintenon, and a nephew of Marie Victoire de Noailles, daughter-in-law of Louis XIV of France. He bore the title of duc d"Ayen until his father"s death in 1766, when he became duc de Noailles.
Career
He served in most of the wars of the eighteenth century without particular distinction, but was nevertheless made a Marshal of France in 1775. He refused to emigrate during the Revolution. Another granddaughter, Adrienne, wife of the Marquis de LaFayette, was saved due to the efforts of James Monroe, then America"s Minister to France.
Adrienne and the Marquis are buried with the Noailles and the other nobles who fell to the guillotine at Picpus Cemetery.
The titles remain among the 4th duc"s descendants in the 21st century.
