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
John Blackwell was born prob. Sandwich abt 1646, son of Michael Blackwell. John died bef 28 Nov 1688 (inv.) He married abt 1673 Sarah Warren and they had seven children (born Sandwich): John (1674), Michael (1676-b1709 no ch.), Desire (1678), Alice (1681), Jane (1682/3), Caleb (c1685) and Nathaniel (1686).
John Blackwell was born Sandwich 26 Dec 1674 and died there prob. shortly bef 6 Jan 1741. He married prob. Sandwich bef 7 May 1701 Lydia Skiffe and they had one child (born Sandwich): Lydia (1716).
Caleb Blackwell was born Sandwich abt 1685 and died Rochester 28 Nov 1762 in his 78th yr. He married prob. Dartmouth abt 1708 Bethia Taber (a descendant of Francis Cooke) and they had seven children (first born Dartmouth, others Rochester): Jane (1710/1), Sarah (c1714), John (1717/8 dy), Mary (1720), Bethia (1722), Alice (1725) and Seth (1729).
Nathaniel Blackwell was born Sandwich 27 Dec 1686 and died Dartmouth abt 1758. He married twice, first abt 1711 Joanna Hathaway (a descendant of Francis Cooke) and second Dartmouth 28 May 1752 Elizabeth ____ Tripp. His children (by his first wife) were: Sarah (1712), Mary (1715), Hannah (1718/9), Joanna (1722-1724), Nathaniel (1724/5) and John (1727).
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.
