In 1666 she married Henry de Lambert, who at his death was lieutenant-general of the army; and she afterwards remained a widow with a son and a daughter, whom she educated with great care. Her house was a kind of academy, to which persons of distinguished abilities regularly resorted. She died at Paris in 1773, aged eighty-six. Her works, which are written with much taste, judgement, and delicacy, are printed in 2 vols. The advice of a mother to her son and daughter are particularly esteemed.
