Hi John,
I used a guy who was born in Swietochlowice but is a guide and has been living in Krakow now but he had researched for me a couple of years ago around the Czuchow area; different archives. His name is Christopher Skutela, PhD, +48504878293, email krisskutela@wp.pl. It is probably a good time to ask as it will be quiet for him in Krakow.
regards
Bob
