She was born to an unidentified Hungarian noble family and owned present-day Lesencetomaj at Lake Balaton in the Kingdom of Hungary in the early 15th century.
[1] Constantin Gane proposed that she was a member of the House of Basarab, stating that she was the first cousin of her husband, Mircea I of Wallachia, for which they could only marry with a special permission issued by the Archbishop of Ohrid.
[2] Historians Petre P. Panaitescu, Constantin Rezachevici and Radu Florescu stated that she was closely related to the Counts of Celje.
[4] On this occasion, Sigismund of Luxembourg, King of Hungary, ordered her to respect the ancient privileges of the inhabitants of Ketzel and to stop collecting duties from them.
[1] Hassan proposes that she died shortly after the murder of her son during an Ottoman campaign against Wallachia in May 1420, because Lesencetomaj was listed among the villages of the royal castle of Rezi on 20 April 1421, showing that her estate had escheated to the Crown.
