My great-grandparents left Poland (Lodz) and immigrated to France in 1913. I always heard that they left for political reasons.
Could someone tell me what could be understood by political reasons in those years? If I have managed to find any trace of my great-grandmother's family, I have never found anything about my great-grandfather Isaac Wenglinski (Piotrkow Trybunalski) in 10 years of research... Prison? Name change?
