Hello. It's good to hear from another Blackwell using DNA testing for research.
My dna can be found at http://www.familytreedna.com/public/Blackwell
Click into one of the ydna results and look for the R1a1 group. That's me. You can compare your results from ancestry.com and see if we're in the same ballpark.
Either way, I'm intereste in your research. There seem to be 2 Abraham's from that era, one in Bladen county married to Nancy, and the more well known one from the Florence SC area married to Sara. Some researchers have their data grouped together, but I'm not convinced that they are the same person. Bladen's data is scarce. I've also not seen any data to link Abraham directly to George from Sampson cty. Thanks for contactimg me, and I hope that there is a dna match. BTW, my email is jblackwell at nc.rr.com
