Travel by ancestry -- to a brand-new Big Y DNA marker uncovered in the Thibodeaux Y DNA surname project

2/23/2021

 
"... 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!
