“Ashkenazi Egyptian Jew a Sephardi German Jew.” – is very common. People always moved back and forth, and routinely intermarried (as they continue to do so). While Jews only intermarried with other types of Jews (or with converts, whose genealogies we had to fake since converting to Judaism was a capital offense), goyim routinely travelled and mixed up genes. A test that says what percentage of ancestry is Ashkenazi is really saying that unlike other Europeans you are Middle Eastern, and that is probably an indicator of Jewish-ness (though remember the Romans recruited Middle Eastern troops for service in northern Europe and left them there when they were discharged.
When some asks me about ancestry, I prefer to reply that I’m descended from Adam ha-Rishon, and ask what they are descended from?
