The Family Tree DNA "Discover" tool (for Y DNA haplogroups and Big Y 700 branches), now in beta test, is a "must to try." Find out how it worked for a Y DNA surname project involving indigenous O-haplogroups originating in Accomack County, Virginia and Somerset County, Maryland. The questions this tool helped us answer -- oh my! See: https://discover.familytreedna.com/y-dna/O-BY60500/story The following two updates, announced on 7/25/2022 and 7/22/2022, relate specifically to ongoing research regarding Asian origins of Native American ancestors, as has been uncovered in the Acadian Amerindian Ancestry DNA Project for descendants of James the Indian, born ca 1656 in Accomack County, Virginia. Citing the original article, Rundquist, M. (2018). "An O-F3288 Y DNA Discovery for Patrilineal Descendants of James Revell (Accomack)." https://www.familyheritageresearchcommunity.org/delmarva-dna/ that was published on the Family Heritage Research Community website, we have the following understanding regarding "James the Indian" and his relationship with the Revell family and surname:
Here's the dilemma: We knew from our research that haplogroups, O-BY60500 and O-FT45548, to which the patrilineal descendants of "James the Indian" belonged, were Asian in origin, but we didn't know the timings of these haplogroups. When had earliest ancestors (and corresponding haplogroup branches) come into being, and how many years had elapsed between upstream and downstream lineages? Were there intervening branches of the O haplogroup tree, that could help us fill the gap between the birth of "James the Indian's" earliest, ancient Asian ancestor in China and this ancestor's descendants in the New World, literally tens of thousands of years later? What would have been a possible migration route from Asia to the Americas for the ancestors of "James the Indian" and their descendants? We were about to have our questions answered, which takes us to the updates that follow: Update 7/25/2022: The newly-introduced and trademarked Family Tree DNA "Discover" tool, currently in beta-test, gives new insights into the Big Y 700 DNA O-haplogroup branches uncovered for the O-haplogroup Revel men who are enrolled in the Acadian Amerindian Ancestry DNA project. Combining inputs from the Family Tree DNA Y-DNA database, ancient DNA, the Time to Most Recent Common Ancestor (TMRCA) algorithm, Dr. Carlos Quiles' research, the work of phylogeneticist Michael Saeger, population genetic studies worldwide, Family Tree DNA group projects, the Genographic Project, and the community, the Discover tool, trademarked by Family Tree DNA, references a target haplogroup label; e.g., O-BY60500 or other, which the user may search using a query form, and (amazingly) projects the time frames for the date of birth of an earliest known patrilineal ancestor, traced from father-to-father, who belonged to that same haplogroup and the tens of thousands of thousands of years that may have elapsed between upstream and downstream branches of his line. A search of the O-BY60500 haplogroup branch, to which the subject of this research, Wesley Revels and other documented descendants of "James the Indian", belong, yielded the following findings and comments (see https://discover.familytreedna.com/y-dna/O-BY60500/story): [Finding]: That the O-haplogroup, O-BY60500 belonged to an earliest ancestor estimated to have been born around 250 years, plus or minus 150 years and that there was a 95% probability that his date of birth would have been between 1628 and 1867. (See: https://discover.familytreedna.com/y-dna/O-BY60500/scientific [Comment]: The estimated date of birth of the earliest known member of this haplogroup, and the documented ancestor of Wesley Revels, corresponds to the date of birth that has been estimated for earliest ancestor "James the Indian" of the Matomkin people of Accomack, Virginia (see https://goo.gl/maps/8itWaxxr7txMmhwg8), given as ca 1656. (See: https://www.espl-genealogy.org/MilesFiles/site/p1086.htm#i108513). [Finding]: That the O-haplogroup, O-BY60500 patrilineal line was formed approximately 5200 years ago (plus or minus 1,200 years), when it branched off from its upstream parent branch, O-FT11768. Downstream members of the O-FT11768 haplogroup include three testers from the Philippines, one tester from Thailand. (See: https://discover.familytreedna.com/y-dna/O-FT11768/story and https://goo.gl/maps/raeQbNztPeGaKC2w6). [Finding]: Included also in the analysis of haplogroup descendants are the members of haplogroup O-BY60500 and downstream haplogroup O-FT45548. Two of the members of the O-FT45548 haplogroup, that was predicted to branch off from the O-BY60500 haplogroup approximately 50 - 250 years ago, are of self-reported Native American ancestries, with one member reporting unknown origins. [Comment]: Estimates for the branching of the O-FT45548 haplogroup from the parent O-BY60500 haplogroup align with TMRCA estimates given as well as reported autosomal DNA relationships among descendants of this same lineage. Update 7/22/2022: A news release from New Scientist highlights recent research regarding scientific proof of an ancient relationship discovered among ancient Asian and Native American peoples: See: Wong, C. (2022, July 14). "Ancient DNA adds to evidence for Native Americans' east Asian ancestry: Genetic analysis of a woman’s skull from 14,000 years ago found in south-west China suggests she was related to an ancient population that migrated to North America from east Asia." New Scientist. https://www.newscientist.com/article/2328757-ancient-dna-adds-to-evidence-for-native-americans-east-asian-ancestry/ Journal reference: Zhang et al., A Late Pleistocene human genome from Southwest China, Current Biology (2022), https://doi.org/10.1016/j.cub.2022.06.016 From the editor: Thanks to the descendants of "James the Indian" of Accomack, Virginia and Somerset County, Maryland, who have participated in the O-haplogroup research that has been a part of the Acadian Amerindian Ancestry project since 2018. Your Big Y DNA test results and other contributions have proved invaluable to these findings!
