Just about all the other tribes in Spain are pretty blended in ~ and, lo and behold, since those folks provided the greater source of immigrants to the Americas, so are Western Hemispheric Hispanics.
At the same time there are plenty of Mediterranean types who can "pass" just the same!
I'm not "the same people" same as my friend last name Schmidt isn't "the same people" as the Nazis. There are cultures and nationalities and faith and heritage that make us different. (To begin with, I'm a Texan).
