The princess was considered a favorite child of her father and one of the most prominent victims of the marriage of convenience in the 15th century.
When this engagement was also dissolved, the next marriage candidate was Duke Henry the Elder of Münsterberg-Oels (1448–1498), son of the Bohemian king George of Poděbrady.
In 1466 Pope Paul II disapproved of the engagement as a "blasphemous connection with a heretic", and Ursula and her father were excommunicated.
Without telling her father, Ursula secretly became engaged to Count Rudolph III of Sulz, Landgrave in Klettgau.
The pope dissolved this engagement, and she eventually married in Cheb (German: Eger), on 9 February 1467, Duke Henry the Elder of Münsterberg.
