Georges de La Trémoille
Georges de la Trémoille( c. 1382 – 6 May 1446) was Count de Guînes from 1398 to 1446 and Grand Chamberlain of France to King Charles VII of France.
He sought reconciliation between Philip, Duke of Burgundy and Charles VII during their estrangement in the latter part of the Hundred Years' War.
De la Trémoille was a political opponent of Arthur de Richemont within the French court.
Most historians take a poor view of his career, assessing that he placed personal advancement before the public interest, though the traditional historical interpretation of the Grand Chamberlain as Jeanne d' Arc's opponent has been revised.
La Trémoille was captured at Agincourt in 1415.
He regained his freedom shortly afterward and dedicated the rest of his career to court life and diplomacy.
He made an advantageous marriage to Joan II of Auvergne( 1378 – 1424), Countess of Auvergne and Boulogne( 1404 – 1424).
De la Trémoille served the Burgundian court for several years, then joined the Armagnac court of Charles VII.
La Trémoille became a royal favourite in 1427.
He gained the title of Grand Chamberlain and was instrumental in Constable de Richemont's expulsion from the court that same year.
Following Joan of Arc's successful campaign to Rheims for the coronation of Charles VII, la Trémoille delayed a march on Paris with fruitless peace negotiations.
He may have been responsible for the lack of royal support that doomed her military actions thereafter.
The historical consensus is that personal jealousies led him to undermine France's two best military commanders during a low point in the war.
In September 1432 he paid for Rodrigo de Villandrando and his routiers to hold Les Ponts- de- Cé against the assaults of Jean de Bueil.
That year de Richemont returned to court and imprisoned la Trémoille the following year.
Charles VII did not intervene.
His daughter Louise de la Trémoille( 1432 – 10 April 1474), Dame de Boussac, married Bertrand VI of Auvergne and had two children:
He also had descents by his two mistresses; by Marie Guypaude, a daughter Marguerite( x and a son Jean the" bastard of La Tremoïlle",( legitimated and ennobled in 1445), a large number of descendants); and by Marie La Championne, Jacques, the other" bastard of La Tremoïlle", legitimized in 1466.

He fought for Henry IV at the battle of Coutras and also at Ivry, and was rewarded by elevation to the peerage, as Duke of Thouars, in 1595.

Thanks to her relations with the houses of Orange and Bouillon, Charlotte-Brabantine played an important part in the French Protestant diplomacy.
