Yaakov Moshe Rosenstein
Ok I have new information.
My great-grandfather was Yaakov or Yakov Moshe Rosenstein and he owned a large print shop in Piotrkow Trybunalski.His children, Shimone (or Shimshone), David, Israel and Frania worked there with him.
Frania was married to Hertzl Grinbaum, who died in the camp Flossberg.
