She was the daughter of general major noble Johan Peter Ingenhaeff and married in 1725 to general noble Michael Numsen. She was given the Ordre de l'Union Parfaite 1753. After the death of her spouse in 1757, she became a central figure in court life, attributed political influence and often criticized. In 1772-1773, she was the head of the court of the crown prince, the future Frederick VI of Denmark, who reportedly liked her very much and called her Mutter.
