Status summary

Completed as of March 24, 2021:

  • Recruiting additional direct male-line Josiah Cooke descendants for NGS/WGS SNP testing - anyone interested in submitting their DNA for testing should contact Raymond T. Wing (email: wing.genealogist AT gmail DOT com)


First Generation

Josiah Cooke (II) was born either at Plymouth or Eastham abt 1649, son of Josiah Cooke & Elizabeth RING Deane. He died Eastham 31 Jan 1731/2. Josiah married Eastham 27 Jul 1668 Sarah, daughter of Giles Hopkins and they had eight children (born Eastham): Elizabeth (1669-1670), Josiah (1670), Richard (1672), Elizabeth (1674), Caleb (1676), Deborah (1678/9), Joshua (1682) and Benjamin (1686/7).

He married Mary ___ and they had at least five children: Desire (1694), Deborah (1696), John (1698), Mary (1699/1700) and Solomon (bp 1711). They likely also had the following children: Joshua (c1702), Elizabeth (c1704), Hannah (c1707) and Jacob (c1708)

DNA Results J2a1-PF5177

Previous testing

The Cook/Cooke/Koch (and Variants) DNA Project Group: J2- Lineage 1 documents three individuals claiming Josiah Cooke as their Most Distant Known Paternal Ancestor (MDKPA) as well as other surnames who are very close STR matches. Plugging in the 111 Y-STR modal values into the NevGen Haplogroup Predictor gives a prediction of: J2a1 PF5191>> PF5177 with a probability of 100%.[1]

NGS/WGS testing

NGS/WGS testing of other known Josiah Cooke Y-DNA descendants (and preferably through his son Josiah) would refine the haplogroup for the family and possibly define subclades for descendants.
