That information is from my own family tree. I had been in touch with the Dzarnowski family a few years back. I have not been able to connect our Twardzik relatives yet. I think Mrukowa holds the key if we can get a hold of the records there. Let me know if you make any progress.
Contact me directly, I may have some Twardzik photos you may be interested to see. Here is my email address in code.
