And you found this out through a DNA test? Not through actual genealogical research?
No one who has invested a mere month of effort in researching his family tree would be surprised by the DNA test findings.
Regards,
A friend tested his DNA thru ancestry.com and was pleased with the results, I had an account with ancestry that I gave my mother who was into genealogy, I decided to test my DNA it came back 25% Eastern European Jew, my mother didn’t believe the results and got her DNA tested it came back 50% Eastern European Jew, the Jewish heritage came they her father who died when she was a child, all we know was he immigrated to the US in the early 1900s and went by the name of Thompson, hardly a Jewish name, he also was an orphan
