Many African American New Hanover County families have ties to Clarendon and Sumter Counties in SC. This may be of interest to you.
Clarendon County SC African American DNA Project
Please join us at http://www.familytreedna.com/public/ClarendonCoSCAADNA/
The project provides a place where persons interested in African American ancestry within Clarendon County, SC (and surrounding areas) can see if their DNA indicates common descent. Though the focus is on determining African American connections, anyone with ties to this area are welcome to submit their results. By doing so, we hope to re-establish family lines that the wall of slavery tried to deconstruct, regardless of race or ethnicity.
I look forward to seeing you there!
