How do I find someone......?

Question:

How do I find someone......?

I am looking for my God-mother. But I don't know her social, and she has married several times so I'm not certain of her last name. All I know is where she was born, her mother's name, that she had an adopted daughter, and that up until '99 she lived just outside of Oakland in California.
If someone could help I would be very appreciative. Even if someone could tell me how to find out if she's deceased. Right now I'm trying to do it without having to pay but if that's my only option then give me a listing of "no bull" sites.

Best Answer - Chosen by Asker: You can try Zabasearch.com, but without knowing what names she's used, it's a crap shoot.

Try the social security death records. You can access this through familysearch.org

Try posting ads on Craigslist.org. It's free and it can't hurt.

And just try googling all the names you know. Who knows what will pop up.
