Previous Y-DNA testing

According to the Southworth-Southard surname DNA Project Subgroup SF02 (Southworths from Samlesbury) includes not only Y-DNA descendants of Constant Southworth, but other Southworth, Sudduth, Southard and even a Davis family. Everyone in this grouping are close STR marker matches so it is possible they share a common patrilineal ancestry in England.

NGS/WGS testing

While none of the claimed descendants of Constant Southworth have ordered a Big Y test, several members of this Project subgroup have Big Y tested and been found to fall under various subclades of R-P312>>L21>DF13>Z39589>S1051>S1050>FGC17980>FGC17990>S1057>FGC17983>FGC46958>FT260574

Further needed testing

We need patrilineal (all male-line) descendants of the Southworth family to WGS/NGS test to confirm their placement and refine the haplogroup further and delineate descendant clades.
