This project is a meeting place for users who share the B2b3a Mitochondrial DNA haplogroup, which means they are related along their maternal lines. Users in this group may want to share their family trees with each other to find overlaps and merge duplicate profiles in order to join or expand the World Family Tree and discover new relatives.
Haplogroup B2 is a branch of the maternal tree of humankind. It is a daughter of the B4b branch. The woman who founded this line lived about 17,000 years ago. This lineage was likely born in the Americas. (Source: [https://haplogroup.org/mtdna/rsrs/l123456/l23456/l2346/l346/l34/l3/...]
One of the mtDNA haplogroups to reach the Americas with the first peoples is B2. It is believed to have traveled over the frozen Beringia landmass that connected Asia to modern Alaska. A subclade of B4b (which is sometimes labeled B2) is one of five haplogroups found among the indigenous peoples of the Americas, the others being A, C, D, and X.

B2b3a was formed about 20,000 years before the present time and its most recent common ancestor is estimated around 3,700 years before the present time. (Source: [https://yfull.com/mtree/B2b3a/])
