Haplogroup T2

What is Maternal Haplogroup T2?

Haplogroup T2 is a genealogical group of lineages defined by unique genetic markers present in your mitochondrial DNA, which is transmitted from your mother. Your maternal haplogroup paints a picture of your ancient origins and the migrations of your ancestors. Although your maternal haplogroup reflects just one of your many ancestral lineages, it carries information about that lineage over tens of thousands of years.

Haplogroup T2 is descended from haplogroup T. Among 23andMe research participants, haplogroup T2 is commonly found among populations in the United Kingdom and Ireland.

It's important to note that your haplogroup doesn't define your current ethnic identity; rather, it provides an insight into your deep ancestry on the maternal side.

Haplogroup T2 is linked to Jesse James

Jesse Woodson James (1847-1882) may be one of the most infamous names in the American Old West. Originally from Missouri, James fought for the Confederates, using guerilla tactics against the Union forces and sympathizers. At the end of the war, James became a full-fledged outlaw, gang leader, robber, and murderer whose reputation is known far and wide in America today.Scientists determined that James' maternal haplogroup was likely T2 through a combination of genealogical and genetic research. James' body was believed to lie in a cemetery in Kearney, Missouri, but modern sleuths lacked proof that the body was indeed the outlaw. So, researchers compared the mtDNA extracted from the body's teeth to the mtDNA of maternal-line descendants of James' younger sister Susan Lavenia James. They were a match, supporting the claim that it was in fact James' body, and providing his maternal haplogroup at the same time.
