Looking for others researching Kaczorowski. They seem to be descended from a Martin Kaczorowski who married Magdelene Kaplan. The 2 sons I am aware of are Mattias and August. Mattias married Johanna (Anna) Wirkus. August married Augusta Zielke/Zielkow. Mattias had 5 children: Lucy, Josef J., August Paul, Catherine R., and Martha. The main line I am researching is August Paul since he married a Sophia Cischosz. Always willing to share what I have found and have been given as, hopefully, we all can help each other.
