Her brother Christoph Frankopan (1482–1527) was Ban (Viceroy) of Croatia under the reign of the Hungarian king John Zápolya.

After the mourning period, King Vladislaus II of Hungary had her married to his nephew, the Hohenzollern prince George of Brandenburg-Ansbach (1484–1543), on 21 January 1509 in Gyula.

[3] After Beatrice's death, only one year after the marriage, George sold the bulk of the Hungarian possessions and purchased several Silesian duchies instead.
