Seems I'm the biggest mutt here.
Highly doubtful, as I for one have you beat, and I’m sure there are many others like me.
I’m all over the board, so much so, that most of it is unknown. I took a class in college that focused a lot on anthropology and one of the assignments involved evaluating your own genealogy. I discussed at length with the professor about my relative washed out bloodlines, and at what point does one simply consider their families natives of the current country of residence (in my case American)?
But, I do have two direct lines that lead somewhere interesting. I’m a direct descendant of Johannes Lichtenwalner of Pennsylvania, and if you travel 4 men back on my father’s side to my great grandfather, he and his wife were Croatian immigrants, which makes me at least 1/8th Croatian. His name was Hrastov (changed to Russell), meaning of or from oak.
