Beatrice was a daughter of Bernardin Frankopan, Knyaz (Prince) of Krk and Modruš (1453–1529) from his marriage to Donna Luisa Marzano d"Aragona, daughter of Giovanni Francesco Marino Marzano, Prince of Squillace.
By marriage she was heiress of Hunyad Castle and Margravine of Brandenburg-Ansbach. Her brother Christoph Frankopan (1482–1527) was Ban of Croatia under the reign of the Hungarian king John Zápolya. Beatrice first married in 1496 to John Corvinus (1473–1504), an illegitimate son of King Matthias Corvinus of Hungary, with whom she had two children:
Elisabeth (1496–1508).
Christoph (1499–1505), the last of the House of Hunyadi Corvinus.
Matthias (1504–1505). King Vladislav transferred all of the Corvinus property to George.
Apart from Hunyad Castle, this included, among others, the fortress of Lipova with 252 villages. Parts of the Bibliotheca Corviniana ended up in Wolfenbüttel, due to Beatrice.
After Beatrice"s death, only one year after the marriage, George sold the bulk of the Hungarian possessions and purchased several Silesian duchies instead.
