She is considered to have wielded a certain influence upon Banér and the Swedish army during the Thirty Years' War.
She was the daughter of George III, Count of Erbach-Breuberg and his fourth wife, Countess Maria of Barby-Mühlingen.
They had two children:[1][better source needed] During her first marriage, she acted as a guardian of Anna Margareta von Haugwitz.
As a widow in 1633, she nursed the first German spouse of Banér, Katarina Elisabet von Pfuel, (former lady in waiting of Maria Eleonora of Brandenburg) at her death bed; Pfuel is said to have asked the two to marry at her death, which they did the same year, on 25 July 1636 in Werbeskans.
Johan Banér, devastated by her death, considered abandoning his posts, but was persuaded to stay.
