Hello Phyllis, Several Questions here. 1st - Do you now your mothers name or just the name she gave you? If you know her name she should be in the census at a younger age showing her parents. 2nd - Have you tried contacting the Adoption Agency. 3rd - Have you requested a copy of the adoption Papers? I was able to to get my fathers adoption records via the Courts in Michigan. You should be able to find the correct agency on your states internet page.
