Paul, I have been in contact with you when you were outside the US. and purchased your first book. I would like to know which lines he is researching. One of my Harris lines fits with some of the Harris in VA. info on the website.
Milly Harris dau. of Joanna and sister of Micajah Harris and that would make so it appears that Martha Harris is or could be the mother of Joanna Harris.The death record for Milly in 1860 says she is the daughter of Joanna Harris and she died in her 90's so it makes sense.

Paul, I think James Harris from Patrick Co. had family members that moved over to Henry Co. which many did so when the county split.
Thank you for giving so much of your time to help others to trace another generation back etc.
