Im trying to find an old girlfriend and only know her maiden name.I have googled,and found search sites,but is there a way I can do it without paying for it?

Not really.

There are ton's of "free" sites out there but all you get for free, is them telling you that they found someone that matches your search, just pay $XXXX for this information.

I don't know of any that are totally free, and reliable.

Try Facebook. Or what about an old high school registry site.

Classmates.com is a great way to find people, but that's also not completely free.

Try a phone book. Especially if she had a brother that would not have a name change, or possibly her parents are still in the area.
