Because America is a "melting pot" or "salid bowl" of the world's nations one can not easily classify its names, but, we can trace linguistic roots, like Hansel (Germanic)

On the other hand, because England is an isolated island and inbred for generations on generations (thank heavens for the invasions or who knows what sort of weak, slack-jawed homosapian samples of genetic disfunction we would find)and steeped in rituals, it has names which can be termed strictly "British" in origin.
