According to some sources,[2][3] she was the eldest child of Géza of Hungary by his first wife Sarolt, a daughter of Gyula of Transylvania.

[4] Though opinions vary about the identity of Bolesław I's second wife, there are a number of researchers who still support the hypothesis of her being the daughter of Géza.

The union (probably instigated by Duke Boleslav II of Bohemia, maternal uncle of the Polish prince) produced a son, Bezprym.

Bolesław soon re-married, this time with Emnilda, a Slavic princess, who bore him five children, including the future Mieszko II Lambert.

Despite Bezprym being the first-born son, he was deprived of the throne of Poland by his father, who largely favored the children born from his union with Emnilda.
