I got confirmation that John Richardson and Nancy Albritton were indeed my 4th g-grandparents. Nancy died in Simpson County in 1825, then John married that Mahaffery woman. So, the Mahafferys are not my cousins, but you might be. (:
One more thing, this is not the same John Richardson that is listed in the First Families. I told their historian that I would just wait to join the Second Families organization.
