Władysław Opolski
Władysław of Opole  (– 27 August/13 September 1281/2) was a Duke of Kalisz during 1234–1244, Duke of Wieluń from 1234 to 1249 and Duke of Opole–Racibórz from 1246 until his death.

Constance, Duchess of Wodzisław
Constance (died 1351) was a Polish princess from the House of Piast and sovereign Duchess of Wodzisław Śląski from 1324 until her death.
Her name appears twice in contemporary sources: firstly, in a letter of Pope John XXII dated 22 September 1321, where she is named "Duchess of Racibórz", and secondly in the "Chronicle of Racibórz", who give her the title of "Duchess of Wodzisławksiężną wodzisławską") and mentions her death in 1351.
None of these sources showed Constance's parentage.
Historians and sources are agreed that she was a member of the Piast dynasty; however, the difficult of establishing who was her father, caused two theories to emerge about her origins.
The first hypothesis states that Constance was the daughter of Duke Władysław of Opole and wife of Henry IV Probus, Duke of Wrocław, who repudiated her after several years of marriage.
She moved to Racibórz at the court of her brothers
Mieszko I and Przemysław, who given to her the district of Wodzisław as her own Duchy, where she remained until her death.
Historians who dispute this theory alleged that Władysław of Opole had a daughter of unknown name, who died shortly after her marriage with Henry IV, or between her repudiation and Henry IV's subsequent marriage.
According to the second hypothesis, based on Constance's titles showed in sources:
Duchess of Racibórz and Duchess of Wodzisław, she was the daughter of Duke Przemysław of Racibórz.
Certainly she remained unmarried and settled in Wodzisław (which probably was her own independent Duchy) until her death.
