From 1380 her father ruled in Dusseldorf as Duke of Berg, where the unmarried Beatrix most likely stayed with the parents.
In the Allgemeine Deutsche Biographie it is said about the husband of Beatrix: Even among his contemporaries Rupprecht I stood in high esteem, he was also a respectful figure, knightly in appearance.
With reckless energy he was considered a benevolent gentleman of good will, a patron of the Church and the priesthood, a friend of widows and orphans.
The Jewish community, whose financial power he knew how to exploit admirably, honored him as a just, humane protector.
Her husband left Beatrix as a widow's portion the castle and city of Neuburg am Rhein, as well as the village of Hagenbach and taxes in kind of Bergzabern.
