Members held peerage titles confirmed by the Parliament of Paris and occupied diplomatic posts in courts such as Versailles, Saint Petersburg, and Vienna. During the French Revolution, the family negotiated preservation of estates through appeals to foreign sovereigns like George III and intermediaries including Talleyrand. Restoration-era politics involved roles under Louis XVIII and appointments associated with the July Monarchy and the Second French Empire.
