It is possible that Gediminas had two more daughters. According to Maciej Stryjkowski, one of Gediminas' daughters was married to David of Hrodna, his favorite war leader. However, some historians disagree with the conclusion that David was Gediminas' son-in-law, expressing skepticism about the reliability of Stryjkowski's sources. The existence of another daughter, or possibly another sister, has been hypothesized based on the list of Metropolitan Theognostus' property published in 1916. The list contains a note describing Andrei Mstislavich, Duke of Kozelsk (ruled ca. 1320 — 1339), as Gediminas' son-in-law. On the other hand, the Ruthenian word ' ("зять") can mean either "son-in-law" or "sister's husband". Hence Andrei of Kozelsk could have been Gediminas' brother-in-law.
