Let's not forget that in one of the missions (don't ask me which one) Tommy has to dress up and impersonate a Cuban. That lends some credence to the theory that Tommy may have been from Cuba or a similar country.
I personally believe Tommy is Italian. Works better for me and makes it a little less like Scarface.
