What do you think is the relative statistical frequency of Balkan last names of American citizens relative to one's of English, Germanic, and Gaelic origin, and why?

And how do you think that ties in with the idea of a name being inherently more likely to be known by foreign groups and associated with that country?

I guess I understand your point though, that Tesla himself is very much an "American" and therefore Tesla is a household American name. Seems we've derailed very far though from the original discussion.
