I am working on my Borland line and began sharing info a couple of weeks ago with the co-editor of the Bourland Bulletin, a newsletter for Bourland/Borland lines. I have not confirmed all the relationships, but some of this info on the Jacksons comes from Augusta Co, VA records. The William Jackson property near Ft. Dinwiddie is now in Bath Co, VA due to reorganization of counties in the 1700s.
