First, in the US, you can't register a trademark that is solely based on a surname. There's a whole set of rules on that. So, your Trademark can't be simply "Newman". .
Actually, the link you provide US TMEP 2009 Chapter 1200 says the opposite - that surnames are registrable as marks if they have acquired distinctiveness (through use).
Edit: You seem to be confusing questions of registrability with questions of infringement. Whether I can register Newman for salad dressing is a different question than whether I can market Newman's Salad Dressing without being successfully sued for TM infringement.
