I have tried Facebook, twitter but have had no success. I want to find a friend I had. She was born when I was ten, making her about 58 now. Her parents divorced so I would like to check divorce records for Ca. hoping for info regarding her. Any free sights for checking records of any kind for info?
I don't know her married name or if she has married. I know the street name where she lived with her parents, her parents name, her brother's name and that's all.

Do you know her married name and are you sure she's in California - or was in California?

Yes, there are ways to find her.
