IGNASIK/IGNASIAK: patronymic nick meaning son of Ignacy or Ignac (Ignatius).
WOLIŃSKI: toponymic tag from such places as Wolin, Woleń, Wolina, etc.
MOLIŃSKI: looks to be a topo tag but the closest potential sources is Молин (Molin) in Serbia; probably the reader wasn't sure whether the letter in fancy script was a W or M (Woliński or Molińdski).
GRYGIEL: derived from Grzegorz (Gregory), esp. Ruthenian version Grigori. Kreigel is a German name which may have been used (or confused with Grygiel) because of its similar sound.
