Lech II le Noir
According to another theory, Constance was the daughter of Duke Przemysław of Racibórz and his wife Anna, daughter of Duke Konrad II of Czersk. Probably born before 1307, is understood that she was the youngest child of Ducal couple. She probably named after Constance, Abbess of Trzebnica and daughter of Duke Ziemomysł of Inowroclaw, while her brother, Leszek, was named after Leszek II the Black (Ziemomysł's brother). Constance probably never married. Until her death in 1351 she lived in Wodzisław Śląski, which certainly represented her personal fief.
