 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
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. To see more of our project mtDNA results, visit our link and set your view to 500, at least, to avoid scrolling: https://www.familytreedna.com/public/AcadianAmerIndian?iframe=mtresults The picture of a people is coming together -- test by test and story by story!  * Analysis of HVR1 mutations yielded a genetic difference of two. 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.

Full Article: https://dna-genealogy-history.com/uploads/3/4/0/9/34098671/petitjean-serendipitous_c4c1_mtdna_finding-final.pdf  The Acadian Amerindian Ancestry DNA Project announces the following addition to the The Acadian Amerindian Ancestry DNA Project Wall of Big Y DNA Markers: The LeBlanc Big Y DNA marker R-FT55255! October 12, 2020 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.

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. In early October of 2020, Acadian genealogist Paul L. LeBlanc of Louisiana, whose BIG Y DNA test from Family Tree DNA of Houston, Texas, was sponsored by the Acadian Amerindian Ancestry DNA project and members of Paul's Acadian Genealogy Groups, shared that his Big Y DNA test results had come in and that he belonged to the R-FT55255 haplogroup. Review of Paul's Big Y DNA test results revealed that he had inherited the Y DNA signature SNP, R-FT55255, which formed a NEW branch of the R-BY592 haplogroup subclade. This new haplogroup, to which Paul and one other LeBlanc man belong, is one-step-down from the R-BY592 haplogroup to which one other LeBlanc man who also traces his patrilineal lines (from father-to-father) to ancestor Daniel LeBlanc of Acadia (b. ca 1626) belongs! The R-BY592 haplogroup is in turn one step down from the R-DF63 branch. It is strongly recommended that LeBlanc men in the Acadian Amerindian Ancestry and other Family Tree DNA projects who have tested positively for the R-DF63 SNP also add the Big Y DNA test to further refine their results! Paul's Big Y DNA test results proved his LeBlanc lineage twice over: once through his meticulous genealogy research and again by way of his matching 111-marker and Big Y DNA test results. Paul's Big Y DNA test results, and those of another LeBlanc man, have now formed a brand-new branch of the Y DNA tree: R-FT55255. It cannot be said enough: Big Y DNA tests are essential for identifying the descendants of specific male ancestors. A Big Y DNA test result may reveal that a descendant is an adoptee, a product of a non-patrilineal event (NPE), or (as in Paul LeBlanc's case) the surname descendant of an ancestor born in the early 1600s! The R-FT55255 haplogroup is one-step down from the R-BY592 haplogroup, which is a branch of the L21 haplogroup. The L21 haplogroup, a subclade of the R-M269 haplogroup (also referred to as the R1b haplogroup), is "the most common Y chromosome subclade of paternal lineages in the British Isles and is also significant in France." (https://www.familytreedna.com/groups/r-l21/about/background) The L21 haplogroup, and those ancestors who belonged to it, came on the scene in Europe during the Bronze Age and proliferated in short order, relatively speaking. The position of Paul's R-FT55255 haplogroup, within the current Y DNA tree, is highlighted in the following graphic: https://www.familytreedna.com/public/y-dna-haplotree/R;name=R-FT55255. If you look one step "upstream" in the tree from Paul LeBlanc's haplogroup, you'll discover three little flags icons that depict the R-BY592 parent haplogroup's European origins. One flag represents France. The other two flags represent Northern Ireland and the United Kingdom.  Acadian genealogist Paul L. LeBlanc provides the following notes about his ancestor, Daniel LeBlanc (spelling variations of Paul's surname include LeBlanc, Leblanc, and LE BLANC):
Modified Register for (1) DANIEL LE BLANC First Generation 1. (1) DANIEL LE BLANC[1,2] was born about 1626. He died 1695/1698 in Port-Royal, Acadia. Location: . 1671 Port-Royal 45a 1686 Port-Royal 60a 1693 Port-Royal 66a . In the 1671 census Daniel had 17 cattle & 26 sheep. In the 1678 census, he had 12 acres and 12 cattle. His sons (Rene, Antoine, and Pierre) were living with him [Source - S White Dictionnaire]. . LE BLANC, Daniel, came from France with his wife, according to ten depositions: five from his great-grandsons (Doc. inéd., Vol. III, pp. 42, 48, 50, 88, 117), four from his great-great-grandsons (ibid., Vol. II, p. 189; Vol. III, pp. 55, 115, 120), and one from the husband of one of his great-great-granddaughters (ibid., Vol. III, p. 54). An eleventh, from his great-grandson Honoré LeBlanc, but in which his grandson Joseph LeBlanc dit Le Maigre seems to have collaborated (ibid., Vol. II, p. 170), adds that this wife was Daniel's second, and that she and her husband had brought with them Marie LeBlanc, the daughter of Daniel's first marriage. Unfortunately, none of the eleven depositions that speak of her French origin mentions this wife's name, but Françoise Gaudet is shown to have been Daniel LeBlanc's wife by four Acadian censuses (see DGFA-1, p. 666). Father Archange Godbout proved through an analysis of various marriage dispensations in an article published in 1952 ("Daniel Leblanc," SGCF, Vol. V, pp. 4-9) that the first marriage was actually Françoise Gaudet's, and that while her daughter was indeed named Marie, she was Marie Mercier, and not Marie LeBlanc. Stephen A. White, Genealogist,Centre d'études acadiennes January 17, 2005 BIRTH: Possibly born in Martiaize, Loudon, Vienne, France Census: Rc PR 1671 45a Rc PR 1686 60a Rc PR 1693 66a . . Charles C Trahan Acadian Census 1671-1752 1671 p 4 Farmer Daniel Leblanc age 45, his wife Francoise Gaudet age 48; their 7 children: one married daughter Marie-Francoise 18, not married Jacque 20, Etienne 15, Rene 14, Andre 1, Anthoine 9, Pierre 7; 18 cattle, 26 sheep, 10 arpents. . DANIEL married[1,2] (1a) FRANCOISE GAUDET[1,2,3], daughter of (1) JEAN GAUDET Jehan and FEMALE, on 1650. FRANCOISE was born about 1623. She died before 1700 in Port-Royal, Acadia. Location: maybe from near MartIaize, Loudon, Vienne, France . GAUDET, Françoise, came from France with her husband Daniel LeBlanc, according to ten depositions: five from her great-grandsons (Doc. inéd., Vol. III, pp. 42, 48, 50, 88, 117), four from her great-great-grandsons (ibid., Vol. II, p. 189; Vol. III, pp. 55, 115, 120), and one from the husband of one of her great-great-granddaughters (ibid., Vol. III, p. 54).

Research of Cajun-Acadian genealogies often reveals that a single individual may descend from the same ancestor multiple times! Intermarriage is indeed a hallmark of many Acadian-Cajun lines which have their earliest roots in Port Royal, Nova Scotia, Canada. Paul LeBlanc is no different from many of his Louisiana cousins in this respect: Paul LeBlanc has fifteen lines from Daniel, from all of his children except Etienne who went to sea never to return and Pierre whose families ended up in Quebec. He has four lines from Stepdaughter Marie Mercier. Within historically Acadian parishes, Acadian brides and grooms having the exact same surnames may be found in marriage records and this trend continues today! Notably, Paul has one LeBlanc - LeBlanc marriage in his Cajun - Acadian lines. 1. (186) VI.I.1.b SIMON-JOSEPH LE BLANC[1,2] [s/o (70) Eienne & (12e) Isabella Boudreau ] was born 16 Dec 1744 and was baptized[3] 17 Dec 1744 in St-Charles-aux-Mines Catholic Church, Grand-Pre, Acadia. He was buried[4] 14 Jul 1810 in Ascension Church, Donaldsonville, Ascension, LA. Baptism: spo Jean Baptiste LeBlanc & Marguerite Halen SIMON-JOSEPH married[5] IV.A.10.e ELIZABETH LE BLANC Isabelle[1,6], daughter of (69) IV.A.10 JOSEPH LE BLANC and (6h) ISABELLE GAUDET Elizabeth Gode, on 21 Sep 1772 in Ascension Church, Donaldsonville, Ascension, LA. ELIZABETH was born 18 Apr 1753 in Port-Royal, Acadia and was baptized 19 Apr 1753 in Port-Royal, Acadia . She was buried[7] 24 May 1815 in Ascension Church Cemetery, Donaldsonville, Ascension, LA.

After Katrina, Paul LeBlanc moved away from New Orleans and now makes his home in Ascension Parish, Louisiana. In fact, Paul lives across the river from where his Le Blanc - Le Blanc ancestors were married back in the late 1700s, and, like his ancestors, Paul's surname at birth was also spelled "Le Blanc." Just this year, Paul learned through research that his middle name was given as "Louis" at baptism -- and not the civil name, "Lewis," which he had used all of his life. Paul wants all to know that his only relatives in the British Isles came over in 1066 (the year of the Norman conquest of England). The Acadian Amerindian Ancestry DNA Project invites all men of Acadian lines to have the Big Y DNA test and add their Big Y DNA test results to the Acadian Amerindian Ancestry DNA Project Wall of Big Y DNA Markers.
