If you read the fine print, Ancestry.com says the Goths count as Scandinavian. I suspect the Pennsylvania Dutch have heavy Gothic ancestry. I have 79 percent Scandinavian ancestry, most of which I assume is from my Pennsylvania Dutch and Scottish heritage. I also have Southern European ancestry, but I expect that through my patrilineal descent from Southern France. Note that up to 10 percent of British people have a Huguenot ancestor, and many Huguenots came from southern France.
