just received 2 (unanswered) calls from this number. Both give the caller ID as George Kulwicki. What's interesting is, I Googled that name, and it is a guy who died in 2000.

interesting...upon Googling the number, several sources (NOT that stupid Hodges Directory) give the owner as a couple (won't put the first names here) with the surname Magyar.  They appear to be real people - the woman has a genuine FB profile, etc. And I found their home address, which is a legitimate one.
