Have it definately to my ggrandfather John Alexander Ferguson b May 3, 1877 
in MO and His father was John L. Ferguson b 1849 in IL.  who married 
Nancy Lauretta Southerlin.  We believe John L.'s father to be John Lewis Ferguson 
b 11.20.1807 in Marine, IL.  If indeed we can prove this via dna testing, then 
John Lewis's Father Is Isaac H. Ferguson b 1773 in Halifax, VA.
