Not sure what to do. I won't to find to find my biological mother but I have limited information about her and limited money to spend what are my best options or what direction should I go?

1. Ask your adoptive parents.

2. contact the adoption agency and ask to leave a letter with your contact information in it in case your birthparents are looking. Your adoptive parents should know which agency they used!
3. Do the same at the courthouse in the county you were born/adopted in. Again, this is information that your adoptive parents should have.
4. Register on reunion websites, such as ISSR, adoption.org and adoption.com

Basically, that's about it for what you can do for free. If you're willing to PAY to find her, I suggest hiring a private detective, but that gets really expensive, really fast.

And actually--how old are you? When did your adoption take place?
