I am Bill Thielbahr, one of the contributors to the Harrell Collaborative (the 14 Families). I have spent a lot of time studying John David Harrell 1763 and his children because they lived in many of the same areas as the Harrells who are part of the 14 Families. I tried several times to find a male descendent of John David’s family to take the Y-DNA test and I failed. I have evidence that this John David Harrell 1763 is not genetically connected to the 14 Harrell families listed in the Harrell Collaborative – I don’t have a Y-DNA profile of John David but I know of a (female) descendent of him whom I know is related to another Harrell who has a Y-DNA profile; this profile shows John David Harrell as not being genetically connected to the 14 Harrell families studied in the Harrell Collaborative. I would like to discuss this further with you but don’t want to engage in a lengthy discussion on the Harrell Collaborative. Please email me at tbar@srv.net . Bill Thielbahr
