Wenceslaus II of Bohemia
Although Fenenna did not play a significant role in the Hungarian court, her marriage did strengthen the alliance between her husband and her uncle Władysław I the Elbow-high, and it also benefited her Kuyavia relatives' relations with, among others, King Wenceslaus II of Bohemia. Shortly after Andrew III's death, their daughter Elizabeth was betrothed to the future Wenceslaus III, who claimed the Hungarian crown.
