My husband is descended through this line - through John D. Walker Jr and Sarah Ann Stephens. I do not have much more than you do, though. I do have Elizabeth Joyner's ancestry back a couple generations. Her lineage resided in Isle of Wright County so maybe we could check there for the Walker's.
After looking at some of the other posts you have made, we have a lot of surnames in common. Let's compare notes...you can email me at firstname.lastname@example.org
