I hope you are still researching the Briggs and available at this email after 7 years. The information you provided about Jesse Briggs, brother of Sarah Briggs Vest is of considerable interest to those of us researching the Briggs of Buncombe/Yancey Co, NC. Some have considered that Jesse Briggs to be the same one who was in Rutherford Co in the1800 and later censuses. I had seen elsewhere that the Jesse Briggs of Stokes Co. married Charity Banner in 1795 and now you show him married first to Nancy Pilkington. This appears to be a totally different Jesse Briggs than the one in Rutherford who married Esther Miller in 1787. The big question is: Do you have the names of the children of Jesse Briggs of Stokes Co?
Also, do you know anything about Frederick Briggs of Surry Co, VA, an uncle of Jesse Briggs, brother of his father Thomas Briggs?
