It's a word list, so as I'm sure you've already figured out, you have to grep first and last names separately. For example, "jennifer" as a first name is token 19786, while "garner</w>" is token 20340. If you want "james garner" instead, looks like that's tokens 6963 and 20340. Except, since it's a word list, there's still no guarantee that either celebrity is necessarily represented until you try.
