This project is a meeting place for users who share the H11b1 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.
H11b1 is a subclade of the Haplogroup H of mitochondrial DNA (mtDNA) 1. It is a rare subclade that has been identified in a few individuals.
I found some resources that might help you learn more about H11b1:
Wikipedia: You can find a brief overview of Haplogroup H and its subclades, including H11b1, on Wikipedia.
FamilyTreeDNA: The Haplogroup H&HV mtGenome Project on FamilyTreeDNA provides information about H11b1 and its members.
Karjalan Sivistysseura: This website provides information about genetic genealogy and mtDNA testing. You can learn more about mtDNA haplogroups and their significance on this website
