Hi Marcin, My name is Barbara Kutra. I live in the United States. My ancestry is from Lithuania, and Latvia, as my great grandparents came here around 1895, and have been unable to trace them. However, that's close enough to Poland, and I always thought maybe there was migration from or to Poland. We may not be related, but I have many questions for you, I will email your personal email address. Maybe we could talk. Thank you so much for posting your message.
