Status summary

Completed as of April 15, 2021:

  • Recruiting direct male-line descendants of John Blackwell for SNP testing - anyone interested in submitting their DNA for testing should contact Raymond T. Wing (email: wing.genealogist AT gmail DOT com)

Still to do as of April 15, 2021

  • NGS/WGS test multiple descendants of Michael Blackwell (and preferably of his son John) to place the family clade as well as test descendants to discover any subclades unique to descendants lines

DNA results J2b-Z2507

Previous Y-DNA testing

The Blackwell DNA Project Group: J2b has one individual claiming Michael Blackwell (father of John) as their Most Distant Known Paternal Ancestor (MDKPA). This individual has not done Y-SNP testing, but has done 67 Y-STR testing. FTDNA predicts they fall under the J2b Haplogroup M102. Plugging in the 67 Y-STRs into the NevGen Haplogroup Predictor Tool gives a variety of subclaces below J2b-M172>M102>Z529>Z1827>Z593>M241>L283>Z622>Z600>Z585>Z615>Z597>Z2507, but also gives a 61.4% chance of it falling under an "unsupported clade".

Further needed testing

We need additional direct male-line descendants of Samuel Rider (and preferably of his son Samuel [II]) to WGS/NGS test to confirm and further refine the haplogroup/clade prediction for the family.
