Is there any way to trace the origins of my great grandfather Arnold Kuhn?
He lived in poland and had a family there I believe towards the end of the 1800s and early 1900s.
At some point he moved alone to Russia and met my grandfather's mother, but they could not marry because his polish wife did not let him divorce. Consequently, my grandfather got his russian mother's name.
Arnold Kuhn died when my grandfather was still very young and they escaped at wartime to Finland where my grandfather grew up.
Is there any way to find the origins of my Polish great grandfather Arnold Kuhn and precisely where he came from?
We have a one photograph of him.
