In 1773, she married marshal Baron, later Count, Thure Leonard von Klinkowström in his second marriage, and with him had four children, among them were the artist Hedvig Amalia Charlotta Klinckowström and Axel Leonhard von Klinckowström, member of the Royal Swedish Academy of War Sciences and Société d'encouragement pour l'industrie nationale.

"[1] She is known to be one of five women to have been a member of the Freemasons in Sweden during the 18th century: alongside Sophie von Fersen, Countess Ulrica Catharina Brahe, and (not as surely documented but most likely) Christina Charlotta Stjerneld.

In 1782, it was noted how the Queen discovered her and her mother alone with the king in his bedroom while he was lying in bed, listening to Monvel reading a play.

This caused a break between Gustav III and the nobility, and it was demonstrated by a social boycott of him led by the female members of the aristocracy: the noblewomen made a political demonstration of their opinions by turning down all private invitations and socializing with him in his capacity of a private person: they demonstrated by visiting the Princesses, Hedwig Elizabeth Charlotte of Holstein-Gottorp and Sophie Albertine of Sweden, who were also known to be in opposition to Gustav III, while at the same time turning down his invitations: this was instigated by Jeanna von Lantingshausen, and Hedvig Eleonora von Fersen belonged to the women who took part in the boycott.

According to Elis Schröderheim, this demonstration made Gustav III lose his former friends, and to spend more time with his male favorites such as Georg Johan De Besche, in which he indulged in ill-reputed orgies with prostitutes.
