Euphrosyne's paternal grandparents were Mieszko I Tanglefoot and his wife Ludmilla, a disputed Bohemian princess from the Přemyslid dynasty. Mieszko was son of
Euphrosyne, daughter of Casimir I of Opole. Ziemomysł's stepmother soon caused conflicts in the family with her attempts to obtain territorial benefits for her own children (the eldest of them was the future Polish king Władysław I the Elbow-high) in detriment of Ziemomysł and his older full-brother Leszek II the Black; some chronicles even accused Euphrosyne of attempting to poisoning both princes, however this wasn't proved.
