Hello. I am replying to your post from 2006 so I hope you are still searching the message board. You mentioned BARNOWIEC, PL. My g-grandfather was also born in Barnowiec! His name was Marek BARNOVSKY. I have no birth or death info but I do find him married to Maria Chlebak in 1878. I also think his father MAY be Joannes Barnovsky.
Could we be related?
