She was the paternal niece of the royal favourite Emerentia von Düben, and her family belonged to the circles of the court.
In 1748, she was appointed hovfröken (maid of honour) to crown princess Louisa Ulrika, who became queen three years later.
In 1756, she was promoted to the position of kammarfröken, when her predecessor Ulrika Strömfelt, was forced to leave court after her involvement in exposing the Coup of 1756.
Axel von Fersen the Elder described her and a typical representative of an ingratiating court noble, and wrote of her: During the Age of Liberty, representatives of the Caps (party) and Hats (party) was known to place their sympathizers as agents at the royal court, particularly women.
[4] Ulrika Eleonora von Düben left court upon her marriage Count Nils Bielke on 14 April 1757.
