Pretty sure my great great grandparents were German. I'd have to double check that. My grandmother's maiden name is pretty German Jewish, but I can't recall at the moment whether she was a first generation immigrant or not. I did some research on this a few years back, and I would have to look at my notes to confirm.

It's a little confusing because there's a actually some German heritage on both sides - the grandmother above was my father's mother, but there's some on my mother's side, too.

Americans are obsessed with genealogy, and I spent some time on it during the pandemic, so I can tell you I'm some odd fraction German, which you usually can't get to, like 5/8ths, because it comes from both families.
