Status summary
Completed as of September 29, 2020:
- Recruiting direct male-line Cushman descendants for further 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 August 29, 2020
- NGS/WGS test multiple Y-DNA descendants of Thomas Cushman to firmly place family clade as well as test descendants to discover any subclades unique to descendants lines
Biography
English Ancestry
Thomas Couchman married Ellen Hubbarde
Robert Couchman aliasCushman married twice, first to Sara Reder at St Alphege parish church, Canterbury, 11 Jul 1606. She died in Leiden, Holland, and was buried on 11 Oct 1616.
First Generation
(Elder) Thomas Cushman was baptized at St. Andrew, Canterbury, Kent on 8 Feb 1607/8, son of (Deacon) Robert Cushman and Sara Reder. His father was the first of his family to spell his name "Cushman" as Robert was the son of Thomas "Couchman". The family soon moved to Holland to join the English Separatist movement there. Thomas and his father emigrated to New Plimouth in 1621 aboard the Fortune.

Previous Y-DNA testing
The Cushman, Couchman surname DNA Project currently lists eight individuals as "Probable Descendants of Robert Cushman, of Kent"[1] All of the testers have only done Y-STR 37 testing to date. FTDNA predicts the family falls under R1b-M269. Plugging in the modal value for the family into the Nevgen Haplogroup Predictor[2] gives a prediction of: R1b DF27>ZZ12>ZZ41 with a 73.3% probability.[3]
Further needed testing
We need additional direct male-line descendants of Thomas Cushman to WGS/NGS test to both confirm the lineage as well as to refine the haplogroup further and delineate descendant clades.
- ↑ but the STR results appear to have far too wide of a spread (ie some have a GD of 10-12 at 37 markers) for them all to be descendants of Robert Cushman. It is much more likely only five or six of these eight individuals are actual Y-DNA descendants of Robert Cushman.
- ↑ Not set for ANY specific haplogroup, since we are only dealing with 37 STR markers
- ↑ The next highest prediction was R1b L21>DF13>CTS1751>Z17966 at 5%, but a 16% chance of it falling into a "unsupported clade".
