Adelaide of Poland( c. late 1170s/ early 1180s – 8 December 1211), was a Polish princess and member of the Piast dynasty. She was the daughter of Casimir II the Just, Duke of Sandomierz and High Duke of Poland, by his wife Helena of Znojmo, a Přemyslid princess. On basis of the inscription of her tombstone at the Dominican Church and Convent of St. James in Sandomierz and two different reports of Jan Długosz, modern historians agreed with the origin and facts from Adelaide's life. Today existed a dominant view in historiography consistent with her filiation and death date. According to them, Adelaide was indeed the daughter of Casimir II the Just and died in 1211, but was n't the foundress of the Convent of St. James and only another nun there. In the 19th century, appeared a theory which states that Adelaide was the daughter of Casimir I of Kuyavia, who entered in the Convent of St. James as a nun and died there in 1291. This view, accepted by several scholars, has been disputed. More recent historiography recognized her as the daughter of Casimir II the Just, founder of the Convent, in which was she buried after her death in 1211.

Euphemia of Kuyavia( c. 1265 – March 18, 1308) was a Kuyavian princess, who was Queen consort of Galicia- Volhynia. She was the daughter of Casimir I of Kuyavia by his third wife Euphrosyne, daughter of Casimir I of Opole. Euphemia was sister of Władysław I the Elbow- high, she was wife of Yuri I of Galicia and mother of Andrew of Galicia and Lev II of Galicia. The only preserved evidence of Euphemia's existence is from Jan Długosz's Yearbooks, which reported that on March 18, 1308 Euphemia died and that she was the daughter of Prince Casimir and the wife of Yuri I, who died in the same year on April 21, which was also his birthday.
