Hi C. Dobrzynski,
This is not in regards to this Post. I noticed that you are researching the name Mroz. So am I. This is one of the harder names to find anything on for me. My Great Grandmother Katherine Machota (nee Mroz)(Born April 12, 1878) and her 2 brothers Peter Mroz and John Mroz came from Piotrowka, Poland.
Any connections?
Thanks,
Paul
