We now have 3 groups in the project.

Group A are the BICKERSTAFF participants that are all descended from a common immigrant.  The earliest ancestor I know of is JOHN BICKERSTAFF who died in FRANKLIN CO. GA, 11 July 1791. 

Group B are the BIGGERSTAFF participants and they show no close relation to Group A.  This group shows a common ancestor.

The last participant is BICKERSTAFFE and shows no close relationship to either Group A or B.
