There are numerous researchers with Fosters of the VA 1700s---Most descend from a Family of Fosters /Forsters immigrating to Colonial Va in the 1600s then migrated toward Carolina and Ga in the 1700s.

Check out the fosterdna.org website. There are several descendants of Fosters from Virginia who have submitted DNA and you can see how close we all are. There are pedigrees as well. You might want to join!
