News and Reflections: "Advanced "Big Y"​ DNA test results reveal Leger surname genetic marker I-BY70584" -- March 23, 2021

3/23/2021

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.
