My name is Jean Carlo Klemann. I was born in Brazil, but my grandfather was Polish. His name is Edward Klemann, he had a sister called Magdalena Klemann. Their parents was Juljus Klemann and Eufrozyna Klemann (Euphrozyna Netzel).
I think they lived near Radom, since their Metryka Urodzenia contains this information. If anyone have some information about this family, please contact me at [email protected]
