Justynian Szczytt was a member of the Szczytt family, which used Jastrzębiec as its coat of arms[REF] (although according to Kasper Niesiecki, it was not Jastrzębiec, but Radwan[REF]).
Justynian's great-grandfather was Mikołaj Szczytt, wojski of Witebsk, who spent 15 years in captivity in Moscow [REF].
