Looking for an old friend and need help?

i live in new jersey, in 1992 i worked in an ice cream parlor called lickity splitz in franklin park, it was owned by gary and judy kowalski. years ago i heard they were divorced, i'm looking for judy, we were friends but i don't know her maiden name. their kids are gary jr, melissa, eric and robert. i've looked on facebook, myspace, clmates and a couple of free people searches and i've had NO luck and i don't have any money for premium searches. if anyone can help me that would be great!
