Assistance in finding birth parents of grandmother-in-law

Question

I'm not sure where or how to start attempting to find birth parents of Martha. We only know that she was adopted and that's about it.

Answer 1

Check if this is the Robert E McGraw she was married to.
His parents are also missing.

Robert's parents aren't an issue because I know who they are. I just haven't added them to WikiTree yet.

I'm looking for Martha's birth parents. Martha was born in Columbus Ohio and adopted into the Jones family. That's all we know about it.

Answer 2

If you are having trouble finding birth parents of adoptees Adoption Angels may be a good place to seek help.

That requires a DNA test. Since Martha is no longer living that is not possible.
