We have had three test kits returned, two for the 67 marker tests and one for the 37 marker test. One is descended from Augustine and Ruth Keeth Hackworth and the other two are descended from John B Hackworth, believed to be brothers. They do match but are off 2-3 markers, two of which are fast mutating markers. That is not unusual considering that their common ancestor, John B and Augustine's father, would have been born in the early 1700's.
