OMG, are we twins?! I found out I had Jewish ancestry last year upon doing a DNA test too, but not quite as much as you show here. And oddly enough years ago, I had started the process of converting to Judiasm after well over 20 years of being fascinated with it and Jewish cluture.
I was rasied Baptist and had no idea of any Jewish in our family. Just Scottish, Irish and African with a tiny bit of Native Canadian. But when the test came back with some European Jewish, my long-standing fascination made sense somehow.
