The repetition of names between our Abrams' is very interesting. Given her date of birth, it appears your Martha was about the age of Elisha & Mary's children. Could she have been a neice? I don't know. I have nothing on Elisha's siblings & parents. I have a picture of Elisha & Mary and looking at it I think they may have been Quakers, but that's just a guess. I know they lived in North Carolina, but not how they got there or when. Their son James Thomas (married Margaret Louise Jones) was the father of my great-grandmother, Sallie Aldonia Abrams. If there is a link to your Martha, I'd love to know what it is!
