 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.

Since the last Acadian Amerindian Ancestry DNA Project update of February 2021, more Thibodeaux men have taken the Big Y DNA test and now a new Thibodeaux branch has emerged on the Y DNA haplogroup tree: R-FT273461.  New Thibodeau Big Y DNA Branches With every new Big Y DNA single nucleotide polymorphism (SNP), or marker, that arises from the Acadian Amerindian Ancestry DNA Project, comes a story of a common Acadian ancestry, as Y DNA is passed virtually unchanged from father to father, a history that traces back generations to 17th-century Acadia (in Nova Scotia, Canada), and a shared culture, with its earliest origins in Europe (most often France) and also the New World.
Such a story is told by the Y DNA haplotree branches displayed in the graphic above. On the left are the new branches of the Y DNA haplotree that have resulted from the Big Y DNA tests of several Thibodeaux men. The Y DNA haplogroup branches shown on the chart are downstream from haplogroup R-M269, a sub-clade of Y-chromosome haplogroup R1b. To the right of each branch is an icon symbolizing the colors of France and the earliest country of origin reported by testers for this historic, Acadian Thibodeaux lineage. While Thibodeaux men descend from Pierre Thibodeaux who was born in France (ca 1631) and married to Jeanne Theriot, the Thibodeaux men who belong to the FT273461, R-FT273430, and R-FT274342 branches of the Y haplotree, that comprise this particular Big Y DNA research, descend from Pierre's grandson, also named Pierre Thibodeaux (born ca 1724 in Port Royal, Acadia) who married Francoise Saulnier. In addition, a new branch, R-FT273461, takes root in a Thibodeaux men, recently from Fordoche, and one other Thibodeaux man who more recently descends from Leon Thibodeaux (born in 1819 in St. Landry Parish) who was married to Celeste Margaret Smith. Another Thibodeaux man, who also descends from this same Leon Thibodeaux, awaits Big Y DNA test results. Downstream is haplogroup R-FT273430, shared by two male descendants of their most recent common ancestor (MRCA) Pierre Cyril Thibodeaux (born ca 1772) who was married to Anna Adelaide Chiasson. A father and son, who also descend from this same Pierre Cyril Thibodeaux, belong to the next downstream haplogroup, R-FT274342. Each new branch of the Thibodeaux Y tree gives rise to more questions about ancestry. More Thibodeaux men who descend from Pierre Thibodeaux (born ca 1724 in Port Royal, Acadia) who married Francoise Saulnier, need to have the Big Y DNA test. If this is your line please contact Acadian Amerindian Ancestry DNA Project administrators to find out how you may participate in Y chromosome and Big Y DNA testing.

Latest Big Y test results have come in for the Richelieu - Leger surname! Thank you to the Leger man who stepped up to participate in advanced Y DNA testing as part of the Acadian Amerindian Ancestry DNA project. Currently there are no matches for this particular Big Y DNA test result and it is unique within the Family Tree DNA database. As more Richelieu - Leger men have the Big Y DNA test, we may find that the haplogroup changes. For now we are showing the distinguishing Richelieu - Leger Big Y DNA Marker as I-BY70584. This line descends from Michel Leger (b. 1729 in Quebec) and Angelique Pinet (b. 1739 in Louisbourg). The widow Angelique Pinet settled on a property in Louisiana in 1787 with her three sons and her name, and distinction as a widow of Michel Leger, may be found on the Wall of Names in St. Martinville. Angelique Pinet descends from Anne Marie (married to the unknown Pinet and then to Rene Rimbault) through Anne Marie's son, Philippe Pinet, who was married to Catherine Hebert. Matrilineal descendants of Anne Marie, traced from mother to mother, belong to haplogroup A2f1a which is Amerindian in origin. The Richelieu - Leger surname line is genetically and genealogically separate from the La Rosette - Leger line (J-M267). View the position of the I-BY70584 branch within the haplogroup I subclade on the Y DNA haplotree. France is noted as the country origin of this particular haplogroup, based upon genealogical research. This line traces back to Etienne (Estienne) Leger b. ca 1630 in France. https://www.familytreedna.com/public/y-dna-haplotree/I;name=I-BY70584. There is one downstream branch with one member reporting origins from England. The Acadian Amerindian Ancestry DNA Project Wall of Big Y DNA Markers Advanced “Big Y” DNA testing offers members of the Acadian Amerindian Ancestry DNA project insights into their surname lines and origins like none other. Big Y DNA testing has proven to be an excellent partner for those engaged with surname studies as Big Y DNA tests pinpoint specific genetic markers, called SNPs, that are unique to individual surnames. That marker is passed from father to father to father, from an earliest-known paternal ancestor to living male descendants who carry an Acadian surname. As with the project, we are inclusive of “allied” surnames as we know that post-exile, many of our Acadian ancestors intermarried with others and their DNA has since become an integral part of our genetic legacy. Because not all descendants of Acadian and allied ancestors have had the Big Y DNA tests, and right now, our Big Y DNA test results are intermixed with other project information, our list is in no way complete, and as we find more of the Big Y DNA results in our project, and new results come in, we will continue add to the list. We hope that the “Acadian Amerindian Ancestry Project Wall of Big Y DNA Markers” will help others in completing their genealogies and as always, inspire more to have Big Y DNA tests. We want to have all of our historic Acadian and allied surnames “on the map.” Please contact project administrators if you have any questions about how to order a Big Y DNA test.

A sub-branch of the Thibodeaux Big Y DNA Dynasty has been uncovered through additional testing of male Thibodeaux descendants and a father and son pair are on it." We have had a Thibodeaux Big Y DNA finding within the Acadian Amerindian Ancestry DNA Project: A sub-branch of the Thibodeaux Big Y DNA Dynasty has been uncovered through additional testing of male Thibodeaux descendants and a father and son pair are on it. They share the same patrilineal (father-line) ancestor, Louis Thibodeaux, b. 1823 -- who lived five generations ago - in common with another Thibodeaux man, whose Y DNA SNP is one branch up, and the father and son are third cousins once removed from him. Along with the SNP finding, all 3 Thibodeux men relate as Big Y matches within the Family Tree DNA Big Y DNA database. Here's what the relationship between the two branches looks like in the Y DNA tree for the Louis Thibodeaux b. 1823 lineage: Thibodeaux Big Y DNA Marker: R-FT273430 Note: This branch is distinguished by 31 SNP markers. There is currently one (1) member of this branch. -- R-FT27342 (sub-branch) Note: This branch is distinguished by 3 SNP markers. There are currently two (2) members of this branch reported by Family Tree DNA. Thank you to Acadian Amerindian Ancestry DNA Project Co-Admin Deadra Doucet Bourke for coordinating the Thibodeaux BIg Y surname study along with the genealogical relationships of the Thibodeaux participants cited here and thank you to the Thibodeaux men who have volunteered to be a part of this fascinating research! --Marie Rundquist, Volunteer Admin Acadian Amerindian Ancestry DNA Project  About the Acadian Amerindian Ancestry DNA Project: https://www.familytreedna.com/groups/acadian-amerindian/about/background
