 Brian L. Doucet Brian Doucet of Nova Scotia Canada has participated in the C-P39 Haplogroup and the Acadian Amerindian Ancestry DNA Projects since 2011. Following Keith Doucet's earliest, confirmed Y DNA test results, in 2008, which first revealed a Native American haplogroup for descendants of Germain Doucet b. 1641 through son Laurent, (see Confirmed C3b Y DNA Test Results Test the Heritage of Cajun Cousin Keith Doucet), Brian, who traces his lineage to Germain Doucet b. 1641 through son Claude, was among the first of the Doucet men from Nova Scotia to participate in the Germain Doucet b. 1641 Y DNA study. The early days of Y DNA testing to prove the Native American lineage of Germain Doucet b. 1641 were interesting times, to say the least. In 2011, when Brian had his Y DNA test along with other Doucet men, genealogists were only just beginning to discover the benefits of Y DNA testing to research a surname line and few in the field knew much about it. In 2011, even fewer comprehended how it was possible that a hidden Native American lineage for Germain Doucet b. 1641 had been uncovered through Y DNA testing! After all, it was (at the time) "settled genealogy" that he descended from Germain Doucet, Sieur de La Verdure of France, right? Certain genealogists did, however, understand the implications of the then-controversial Y DNA findings for male descendants of the Germain Doucet b. 1641 line. One genealogist in particular, Paul Tufts, of Nova Scotia, who has an extensive background in the biological sciences, was instrumental in getting the word out about the Germain Doucet b. 1641 Y chromosome DNA study. During those early days of Y chromosome DNA testing to prove the Native American origins of this line, Paul would meet face-to-face with male descendants of Germain Doucet b. 1641 (who were, after all, friends and neighbors!) and he told them about the project, answered their questions, and convinced them to have the tests. Brian was among the first of the Doucet men in Nova Scotia to volunteer to have his Y DNA tested, and to share his results. Brian wondered if his Y DNA test results would show that he too belonged to what was then called the C3b haplogroup (now called C-P39), as did other Doucet men who traced their patrilines, from father-to-father, to Germain Doucet b. 1641. Brian's Y DNA test results, and his close, Y chromosome DNA matches with other Doucet men, who traced their lines to the same common ancestor, Germain Doucet b. 1641, proved that he did. Brian has since had additional testing that qualified his membership in the C-P39 Y DNA haplogroup, as have other men who trace their patrilines, from father-to-father, to Germain Doucet b. 1641. Fast-forward to the summer of 2022 when Brian, after having read about the latest advances within the "Doucet DNA" project, emailed DNA project manger, Marie Rundquist, and gave her permission to share his story and his genealogy (through Germain Doucet b. 1641's son Claude). In the same email, Brian also reflected upon his pivotal role in a 2012 White Paper that detailed project findings: Quoting from a White Paper Marie had written in 2012, "C3b Y Chromosome DNA Test Results Point to Native American Deep Ancestry, Relatedness, among United States and Canadian Study Participants," Brian shared in his correspondence, "I have to admit it was an odd (in a good way) feeling when I had read through the report and came upon my results being utilized: "Results of representative test kit 219075 (Doucet) were analyzed against thirteen others in the study. As illustrated in the MRCA % Probability Chart for kit 219075, when one Doucet descendant’s results are compared against thirteen other study participants, the highest probability for sharing a common ancestor at twelve generations -- a genealogically relevant timeframe - is greatest among Doucet surname descendants ..." Brian's remark highlights how one set of Y DNA test results (his), identified only by a kit number and the Doucet surname, were instrumental in (1.) establishing, by comparison with other Y DNA test results in the project, a First Nations / Native American lineage of male descendants of ancestor, Germain Doucet b. 1641, and (2.) helping to refute any possibility of a genetic, father-son relationship between Germain Doucet Sr., founder of Acadia, and Germain Doucet b. 1641 of Port Royal, Nova Scotia. By 2017, only after dozens of male, patriline descendants of Germain Doucet b. 1641 had added their matching Y chromosome DNA test results to the project, were the following outcomes firmly established for the Germain Doucet b. 1641 Y chromosome DNA study: The discovery of a Native signature for descendants of Germain Doucet b. 1641 by our projects (the first descendant of this line having tested with the Acadian-Amerindian DNA project in the Summer of 2008) had great significance for the descendants of Germain Doucet b. 1641 because the Native Y DNA signature attained for this line (1) disproved a European ancestry for Germain Doucet b. 1641, (2) disproved a father-son relationship between Germain Doucet b. 1641 and Germain Doucet Sr. of France and (3) disproved that Pierre Doucet (b. ca 1621) and Germain Doucet (b. 1641) were blood brothers having descended from the same father. Brian Doucet graciously shares his own Nova Scotia lineage to Germain Doucet b. 1641 through son Claude, tracing his line from father-to-father, beginning with himself. Brian provides the following names of each of his patriline ancestors (all Doucet men) and their spouses for each generation: Germain Doucet (b. 1641) + Marie Marguerite Landry Claude “dit Maitre Jean” Doucet + Marie Comeau Joseph Doucet + Anne Agnes Surette Michel Doucet + Marie Suzanne Mius David “le Grand” Doucet + Isabelle Mius Jean Robert Doucet + Marie Henriette Saulnier Alexandre “Killick” Doucet + Marie Jane Newman Alexandre “Sandé” Doucet + Catherine “Katie” Comeau Alfred “Fred” Doucet + Cecile Comeau Brian Louis Doucet 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., C-P39 or other, which the user may search using a query form (see https://discover.familytreedna.com/).
The Family Tree DNA Discover tool (amazingly) projects the timeframes 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 years that may have elapsed between upstream and downstream branches of his line. For example, the Discovery tool estimates that the first ancestor who belonged to Haplogroup C-Z30754 would have been born approximately 400 years ago (check!). Then, it provides estimated timeframes between intervening Big Y 700 branches, defined by leading SNPs (or markers) that separate C-Z30754 from the root, C-P39 Y DNA haplogroup that is estimated to have branched off from its parent subclade, some 11,000 years ago, plus or minus 2,100 years. Explore the features, referencing haplogroup C-Z30754, the signature, Big Y 700 DNA haplogroup attained for the descendants of Germain Doucet b.1641.

Thanks to all members for your participation in the C-P39 Y DNA Project, the Acadian Amerindian Ancestry DNA Project, and thanks also to the vast numbers of men who have taken the Big Y 700 DNA test, including the male descendants of Germain Doucet b. 1641. Your test results were immensely helpful in producing these estimates!!!  Reference: https://www.familytreedna.com/public/y-dna-haplotree/C;name=C-P39 New branches are showing up in the C-P39 Y DNA haplogroup for men of Native lines in the American southwest (C-BY56288) as well as descendants of Germain Doucet b. 1641 -- through his son Laurent! As new members join the C-P39 Y DNA haplogroup, and have the Big Y DNA tests, new markers emerge that add branches to the C-P39 tree that differentiate among North American lineages (and keep genealogists up at night!).
It is truly remarkable to find that male, father-line descendants of Germain Doucet b. 1641's son Laurent, who migrated to Louisiana following the forced exile of Acadians by the British, from Nova Scotia (which began in 1755), share a new branch of the Y DNA tree - and it appears that this branch, presently defined by the marker C-BY92312, is exclusively their own! An earlier blog post, dating back to April of 2017, has been updated for consistency purposes and now contains the following up-to-date information: Y chromosome DNA is only held by males - so the C-P39 Y DNA marker traces only through paternal lines. This above chart represents the present C-P39 Native Y DNA haplogroup phylotree. From limited data we had from earlier DNA studies, referencing a small group of men, this Y DNA haplogroup was found to have an "Athabascan" tribal connection in North America. The C-P39 Y DNA study (that has been ongoing since approximately 2008) included men belonging to this haplogroup who trace earliest male ancestor locations to all regions out of North America including the Pacific Northwest, the American Southwest, the Appalachian region, Louisiana and Texas, and Eastern, Midwestern and Western Canada. Updated C-P39 Y DNA haplogroup project data also includes the "diaspora" locations of descendants of Germain Doucet b. 1641 because a Doucet line -- the male descendants of son Laurent - was essentially split off from others when the Acadians, including those of Native ancestry, were deported from Nova Scotia in 1755 by the British. Now, based on advanced Y DNA testing of a much larger population of men (whose ancestries trace to all regions of North America), this rare C-P39 Y DNA haplogroup has a broader distribution, geographically. As more results come into the project -- as more men participate in the advanced Y DNA studies - this chart will continue to be updated. C-P39 Y DNA Project Updates Update 12/14/2021: A new subclade of the C-Z30754 branch has been identified through Big Y DNA testing: C-BY92312. As shown in the phylotree above, the C-BY92312 branch is one-step down from the C-BY101109 branch (identified in update 07/12/2021) which in turn is one step down from the Z30754 branch (a subclade of the C-P39 haplogroup). At this time, the new subclade, C-BY92312, is unique to descendants of Germain Doucet b. 1641 through his son, Laurent. Members of the C-BY92312 subclade will appear as Y chromosome DNA matches to other men descending from Germain Doucet b. 1641 and will test positive for the C-P39+ SNP and the C-Z30754+ SNP. A new subclade, C-BY56288, also shown in the phylotree chart above, has been identified for men belonging to C-P39 Y DNA haplogroup subclades, whose origins trace to the American Southwest. Update 07/12/2021: A new subclade of the C-Z30754 branch has been identified through Big Y DNA testing: C-BY101109. This branch is one-step down from the C-Z30754 branch (a subclade of the C-P39 haplogroup) and is unique to descendants of Germain Doucet b. 1641. Members of the C-BY101109 subclade will appear as Y chromosome DNA matches to other men descending from Germain Doucet b. 1641 and will test positive for the C-P39+ SNP and the C-Z30754+ SNP. Update 05/06/2019: The C-Z30754 single nucleotide polymorphism (SNP), or genetic marker, has been identified as unique to male, patrilineal (father to father) descendants of Germain Doucet b. 1641 through advanced Y DNA testing. Y chromosome DNA is inherited through patrilineal line of descent and is passed, from one generation to the next, virtually unchanged, from father to father. Y chromosome DNA tests are separate test from autosomal DNA tests and are for males only. The C-Z30754 marker also identifies a new subclade of the C-P39 Y DNA haplogroup to which male descendants of Germain Doucet b. 1641 belong. Male descendants of Germain Doucet b. 1641 who have had advanced Y DNA test will show this marker in their results. Update 04/29/2017: Results from advanced Y DNA testing by men participating in the C-P39 Y DNA project have been placed on the map. A Savoy man out of New Brunswick, a Mi'kmaw Broome Man out of Quebec (Gaspe) have been found to share the same Y DNA haplgroup marker: C-BY22870+ and both men belong to this new C-P39 Y DNA haplogroup subclade. As a result of this latest C-P39 haplogroup tree update, the Savoy and Broome man no longer share the same Y haplogroup subclade with the Newfoundland man, Wejitu, whose C-P39 Y DNA haplogroup subclade remains BY18405+. A Mills man and a Fortune man out of the Appalachian region of the United States had tested positive for the C-P39 Y DNA SNP. Subsequent Big Y DNA test results have yielded that both men belong to the same C-Z38940+ subclade of haplogroup C-P39, offering new possibilities for a deep ancestry connection among the two families. Update 08/04/2018: Visit the Family Tree DNA C-P39 Y DNA Project site for up to date results: https://www.familytreedna.com/groups/ydna-c-p39/about/background Update 9/7/2017: Through exhaustive Y Chromosome DNA testing of numerous male, paternal line Doucet / Doucette descendants of Germain Doucet b. 1641, who was from Port Royal, Nova Scotia, Canada, our Acadian-Amerindian and C-P39 Y DNA projects have uncovered, validated, and then verified a Native American Y Chromosome DNA haplogroup signature (originally referred to as haplogroup C3b and now referred to as haplogroup C-P39) for his descendants– through sons Charles, Claude and Laurent. The discovery of a Native signature for descendants of Germain Doucet b. 1641 by our projects (the first descendant of this line having tested with the Acadian-Amerindian DNA project in the Summer of 2008) had great significance for the descendants of Germain Doucet b. 1641 because the Native Y DNA signature attained for this line (1) disproved a European ancestry for Germain Doucet b. 1641, (2) disproved a father-son relationship between Germain Doucet b. 1641 and Germain Doucet Sr. of France and (3) disproved that Pierre Doucet (b. ca 1621) and Germain Doucet (b. 1641) were blood brothers having descended from the same father. Having the Native Y DNA haplogroup signature for this line also helped correct errors that have since been discovered in genealogies for Doucet men who were thought (at one time) to have descended from Germain Doucet b. 1641, but, through Y DNA testing, were discovered to have descended from Pierre. As a result of this finding, Doucet descendants question the relationships of individuals once thought to be the offspring of Germain Doucet Sr. of France as well.
