Martha Neville & Wallace Edmonds

I am searching for descendants of Martha Neville who m. Wallace Edmonds. They lived in Emile, AL. I have no names of children, but I do have correspondence dated Nove 30, 1962, where she mentions grandchildren and specifically a grandson named David (surname unknown). There was a reference in this letter to a family Bible of her Ramsey line, and I would like very much to find the person in posession of it, so that I could get a copy of the information recorded there as transcribed in the letter.
Since that was written, she and the recipient of the letter have died and we do not know where the Bible is.
I have more information on the Ramsey and other branches of this family and would like to share.
