I don't believe I can help with your Bagbys. My Bagbys trace back to Buckingham County, Virginia. The approximate date of birth of my John Bagby would be 1770. He married Elizabeth Bates in 1793. He had a brother, James, who married Elizabeth's sister, Sarah Bates. Much of the family has been traced from John up until now and I have not found a Nancy Bagby. I wish I could help.
