Claude-Anne de Rouvroy de Saint Simon

[2] He distinguished himself in the campaign, particularly at the Siege of Yorktown, where he commanded the left wing and barred the roads toward Williamsburg, thus preventing the British under Lord Cornwallis from escaping the encirclement by land.

[4] Elected on 30 March 1789 by the Bailiwick of Angoulême as deputy for the nobility to the Estates General, he protested against the reforms and the abolition of noble titles, and as an ultra-conservative tried to stop the course of events.

When Napoleon invaded Spain in 1808 and started the Peninsular War, the authorities in Madrid called upon Rouvroy to defend the city.

He was freed by Cossacks in 1814 and his sentence was annulled by letters patent from the new king Louis XVIII, who further declared that he had served the House of Bourbon well through his loyalty.

[6][7] He married on 1 April 1773 with Françoise-Louise Thomas de Pange, daughter of a Lorraine councilor in Parliament, with King Louis XV a witness.
