That's why I posted for assistance here: I don't know where (what sites) to go with this info. All commonly known sites return too many hits on this "first lastname" even in person's known town/state. And cell# (likely prepaid) and email address (likely throw-away) are not known to any of sites I tried. Of course, D.O.B. would solve it, but I don't know how to get it from Hertz
