The Thibodeaux Y haplotree has another new branch! 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. 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.

Serendipitous DNA Discovery Uncovers Rusty Petitjean's Hidden Native Ancestry By Marie Rundquist with Deadra Doucet Bourke, Administrators Acadian Amerindian Ancestry DNA Project November 1, 2020 “…when Rusty’s mtDNA test results came back I was absolutely stunned …” If the Acadian Amerindian Ancestry DNA project were to have one, single, underlying characteristic to which we owe our most spectacular and unexpected DNA discoveries, it would have to be “serendipity.” The Merriam Webster Online Dictionary (www.merriam-webster.com) defines serendipity as “the faculty or phenomenon of finding valuable or agreeable things not sought for.” “Serendipity” perfectly describes how Rusty Petitjean discovered his earliest Native ancestry only after his mitochondrial DNA (mtDNA) test results came in. Click here to read the article! Update January 26, 2021: Since the publication of this article, another documented, matrilineal (mother-line) descendant of Marie Ouacanteous Rouensa b. 1677 and d. 1725, the daughter of Rouensa, Chief of the Kaskaskias, has had the full mitochondrial sequence mtDNA test, where markers at the HVR1, HVR2 and coding region are compared. The latest full mitochondrial sequence mtDNA test results, received January 26, 2021, which matched Rusty Petitjean's results, were confirmed by Family Tree DNA as belonging to the C4c1 mtDNA haplogroup and therefore validate the lineage and the Native American origins of Marie Rouensa, established by the original article. The Acadian Amerindian Ancestry DNA project wishes to thank Fr. Jason Vidrine and other members for providing their gracious assistance in sponsoring this latest match's full mitochondrial sequence mtDNA test and locating descendants of this historic line! This is what the C4c1 mtDNA match looks like in our Acadian Amerindian Ancestry public mtDNA test results page (see attached snippet). Displayed are the DNA test kit numbers, the earliest mother-line ancestor (Marie Rouensa), the United States country origin (indicating Native American ancestry in this case), the mtDNA haplogroup (C4c1) and the HVR1 and HVR2 mutations.* Coding region markers are not displayed on Family Tree DNA project websites.

HVR2 and coding regions were identical. Each kit possessed the distinguishing marker for the C4c1 mtDNA haplogroup (T1243C) in the coding region and there were no missing markers.
