I just recently found your question regarding Lonowski's in Poland. My great-grandfather was John Lonowski (son of Martin; wife of Susan Larchik.) In case you don't have that information, I would be happy to share what I have. My records only go as far as Martin. Please email me directly to my email address: mjones23@neb.rr.com as I am not a member of Ancestry. I'd love to know what you've found back to Poland! I am a Facebook friend of a "Tomasz Lonowski" in Poznan, Poland, and while I'm certain we are related, his parents were divorced when he was yound and he doesn't know much family history on his father's side. :-(
Thanks so much for your reply!!
