Please see my 26 Oct 2012 followup / correction. As you have discovered, there is a lot of misinformation both online and in various publications. My ancestor John MAXWELL, who imported himself and his family to Orange Co., VA, in 1740, is not related to the John MAXWELL who married Mary CARSON. Proven by DNA tests.

; my family is Group 7. Over the years, my cousins and I have scoured the extant records for 18th century Augusta & Rockbridge Counties (plus other records, too). No birthplace or date has been found for my John. We know we descend from him, but we may also descend from John Jr., too. Please contact me privately if you wish to pursue this.
