Constant d'Aubigné (French pronunciation: [kɔ̃stɑ̃ dobiɲe]; 1585 – 31 August 1647) was a French nobleman, son of Théodore-Agrippa d'Aubigné, the poet, soldier, propagandist and chronicler.
Born into a Huguenot family, Constant led a less structured life, first embracing Protestantism and then the Catholic causes, visiting England and then in 1626 betraying the Protestants by revealing English plans to take La Rochelle.
[1] Richelieu had d'Aubigné and his family imprisoned at Niort in 1629 for correspondence with the English.
His second wife, Jeanne de Cardilhac, was the mother of Charles (father of Françoise Charlotte d'Aubigné), Mme.
The d'Aubigné line was continued through Anne Marchant's son, Theodore (1613–1670) [citation needed].
