The Dewhurst Family DNA Project

It is with great sadness that I share that we have lost my long time "partner in research," Terry Tammany Dewhurst, who for years has managed the DNA portion of our One Name Study. Here is her Obituary:

Theresa Noreen Tammany Dewhurst

Theresa Noreen (Tammany) Dewhurst, 70, a longtime resident of Glen Rock, NJ and Bradenton Beach, FL, formerly of Brooklyn, NY, passed away on Saturday, September 30, 2017. She was a parishioner of St. Catharine R.C. Church in Glen Rock. An avid world traveler, Terry also enjoyed being a part of many Genealogical Societies, researching generations of family history as well as restoring old photos.
Beloved wife of the late Richard Dewhurst. Loving and devoted mother of Susan Dewhurst, Jeanne Dewhurst, James Dewhurst (Leslie) and Thomas Dewhurst. Dear stepmother of Lynne Dewhurst-McBurney (Bryan). Cherished grandmother (Momo) of Julia, Nicholas, Amelia, Duncan, Lily and Paige. Dear sister of the late Virginia Tammany. Daughter of Edna Gertrude Smith and the late James Tammany.

 

This project grew out of our shared stories and experiences on the DEWHURST / DEWHIRST mailing list and message boards. Jana Black manages the mailing list and the website. Terry Dewhurst managed our message boards and the DNA studies until her death. We pooled our efforts to keep track of the DNA study, results of which can be seen here: We welcome any and all variations of the surname. Please join us. Test results will be posted, compared and associated where possible as they come in to show likely familial connections.

Project Goals:
Though many connections have been made using the traditional methods of genealogy, the Y-DNA study offers us a whole new opportunity to find others who may be releated to our lines. The testing is simple and painless, involving a cheek swab. Only a male in the direct line will have inherited the Y-DNA, so the females will need to ask a male DEWHURST relative to participate. Through this group surname project, FamilyHistoryDNA.com will give a discount on the test fees. Subsequent matched individuals can and may want to move up to more markers later on.

[1] CLUSTER THREE includes several sub-groups which have matching DNA results, but for whom we cannot yet prove the "paper trail" into the descendancy lines of Roger Dewhirst of Whalley, 1505. Therefore they are posted with the earliest proved ancestor until we are able to sort it out.

* Haplogroup I - The I, I1, and I1a lineages are nearly completely restricted to northwestern Europe. These would most likely have been common within Viking populations. One lineage of this group extends down into central Europe.The ancestors of Haplogroup I (defined by the P19 and M170 genetic markers) arrived from the Middle East 20,000 to 25,000 years ago and are associated with the Gravettian culture. Gravettian is the second subdivision of the Upper Paleolithic technological phase in western Europe (from 27,000 to 21,000 years ago). Haplogroup I is most frequent in central Eastern Europe and also occurs in Basques and Sardinians. Haplogroup I is found in Central and Eastern Europe, but also accounts for almost all the HG2s in Northern Europe and the British Isles. Gravettian culture A phase (c.28,000-23,000 ya) of the European Upper Paleolithic that is characterized by a stone-tool industry with small pointed blades used for big-game hunting (bison, horse, reindeer and mammoth). It is divided into two regional groups: the western Gravettian, mostly known from cave sites in France.

The I1a subclade of Haplogroup I is estimated to be 15,000 to 20,000 years old and confirmed by the single nucleotide polymorphism (SNP) known as M253. According to the Genographic Project, the founder of the I1a branch lived on the Iberian Peninsula during the Last Glacial Maximum or LGM. While many I1a members trace their ancestry to Scandinavia, others find their roots in the British Isles, Germany, and beyond.For more info, click here or join the yDNA Haplogroup I Subclade I1a group.
