How can I find my mom I never met? I only have a first and last name and place of residence, I'm not sure if it was the birthplace.

If you were abandoned/left with your father or other adult, you could ask them. If you're not comfortable with that, check ZabaSearch, WhitePages, or Google for their names. Since you have a place of residence, you can check RealEstate and see who owned the house/apartment around the time your mother lived or stayed there. Then you can track the owners down and get more info.Using ZabaSearch, you can run her first name and address through their database and hopefully find something. Warning, if it was a closed adoption, all her records are sealed.
