His daughters were Dorothea, Recha and Henriette, all brilliantly gifted women.
Marie zealously pushed her favourite towards office, and had gone so far as to absent herself from court for three months on account of the king's persistent refusal, when Charles, duc de La Vieuville, then head of the council, in need of her aid in his negotiations with reference to the marriage of her daughter Henriette Marie, finally agreed to force Richelieu's appointment to office upon the king, Louis XIII.
The duke married Louise Henriette de Bourbon-Conti, who bore him a son Philip (Egalite), duke of Orleans, and a daughter, who married the last duke of Bourbon.
His mother, Henriette de Chandieu, died at his birth; and his father, Juste Arnold de Constant, commanded a regiment in the Dutch service.
