The Pineton de Chambrun is a French aristocratic family, of which several members have taken an important part in French politics. Their nobility was proven in 1491. The Pineton de Chambrun originally come from the Gévaudan region, and many members were mayors or deputies of Lozère.
Descendants include direct lineage of the Marquis de Lafayette, through the wedding of Marie Henriette Hélène Marthe Tircuy de Corcelle, granddaughter of Marie Antoinette Virginie du Mottier de La Fayette, at the Église de la Madeleine in Paris, on 8 June 1859, with Charles Adolphe Pineton de Chambrun, a lawyer in New York. The descendants of Marthe Tircuy de Corcelle and Charles Adolphe Pineton de Chambrun include:
Pierre de Chambrun was elected deputy under the Third Republic then senator of the Lozère department. He was part of the Vichy 80minority group of French elected parliamentarians who, on 10 July 1940, voted against the constitutional change that dissolved the Third Republic and established the state of the Vichy régime under the leadership of Marshal Philippe Pétain. Pierre de Chambrun became a member of the Provisionary Consultative Assembly in 1944–1945.
Charles de Chambrun, diplomat and writer, member of the Académie française.
**Charles de Chambrun, grandson of Charles and nephew of Gilbert de Chambrun, was an administrator of societies, and mayor of Montrodat. Gaullist deputy of Lozère from 1962 to 1973, he was named Secretary of State to Foreign Trade in 1966, during the third government of Georges Pompidou. From 1986 to 1988, he was deputy of the Gard department as a member of the National Front.
*René de Chambrun, lawyer at the Court of Appeal of Paris and in the Bar of New York, and president of the Baccarat Cristalleries. René de Chambrun married Pierre Laval's daughter Josée, and who later defended, post-war, Laval's memory. He bought the Château de la Grange-Bléneau, a castle in the commune of Courpalay in the Seine-et-Marnedépartement of France, from his cousin, Louis de Lasteyrie, a descendant of La Fayette, in 1935, with a life tenancy. Upon Lasteyrie's death in 1955, René de Chambrun discovered the large cache of documents in the attic, and founded a private museum to Lafayette. He organized and described the family archives, a collection dating from 1457 to 1990. The papers were microfilmed at La Grange in 1995 and 1996, for the United States Library of Congress.
