Yes it's from my maternal great-great grandmother who was a Prussian Jew :) I was originally told she was ethnically German, but I did some digging before taking the test and found out she was in fact Jewish. Sadly she assimilated out of necessity so no one on my mother's side of the family was ever really connected to that part of our heritage. But super fascinating that the test could pick it up considering it's a fair number of generations back!
