23. Zofia (Sophia) * 1449/1453 + 1478/1479
The daughter of Bolesław II and Princess Anna. She married Wiktoryn of Podĕbrady, Prince of Ziębice and Opava in 1474. The union came about owing to the efforts of her uncle, Prince Przemysław II, who hoped to enter into an alliance with Matthias Corvinus, King of Hungary and Bohemia by taking advantage of Wiktoryn's links with him. As the wife of Wiktoryn she could use the title not only of Princess of Ziębice and Opava but also Countess of Kłodzko, Lady of Podĕbrady and Kunstat.
