The entire pedigree for John Williams Graves ( Virginia's father) can be found at http://www.gravesfa.org/gen169.htm

I think you will be pleasantly surprised.
I have been unlucky in finding more info regarding her other two children, John and Charles. Everyone seems to have moved from Mississippi to Atkins, Arkansas sometime after 1880.
I will gather what I have for you. I do have a picture of Martha Rose Dorsey, if you are interested.
Might I ask where you fit into this giant puzzle?
I am seriously in search of Dorsey ancestors.
