She maintained numerous friendships with the intellectual and political elite of her time, including Johann Wolfgang von Goethe and Louise of Brandenburg-Schwedt.

Friedrich Nicolai, publisher and friend of the house, wrote of her: "... a rare woman, in spirit, heart and knowledge.

While the son was taught by a tutor, Jenny received lessons from her mother and a governess who was a friend of the family named Lindemann, who later became the wife of the Osnabrück lawyer Graff.

At the family's request, she became engaged in January 1768 and married on May 4 of the same year with Privy Councillor Johann Gerlach Jost von Voigts (1741–1797) from Celle.

Voigts initially became director of the newly founded Osnabrück lottery through the mediation of Justus Möser and was given the title of councillor.

She soon found the childless marriage a burden, but accepted her fate by taking in foster children and financing their upbringing.

During numerous spa stays in Bad Pyrmont, to which she accompanied her father, she made the acquaintance of a number of writers.

Despite the couple's frequent visits to each other, Jenny ran her own household in the house in Hakenstrasse in Osnabrück that she had inherited from her father.
