Henrica Juliana was the daughter of the riksråd, count Hans Henrik von Liewen the Elder, member of the house of Lieven, and Magdalena Juliana von Tiesenhausen, and the sister of riksråd count Hans Henrik von Lieven the Younger, future governor of Swedish Pomerania and Marshal of the Realm.
Louisa Ulrika described her in a letter to her mother: "... a girl with many merits and who had the mind of an angel, gay, cheerful and very strong."
[5] In 1748, she married lieutenant colonel baron Carl Hårleman at Drottningholm Palace and retired from court.
It was well known that a great part of the Senate gathered in the salon of Lieven to proof read the paper.
Her political activism made her the target of slander: the caps politician Johan Arckenholtz accused her of having had an affair with William VIII, Landgrave of Hesse-Kassel during his visit to Sweden in 1732 and of having had a child with the Hessian president Dörnberg.
