Haplogroup H3k1a is a branch on the maternal tree of humanity. It is relatively young.

Members appear in GenBank from four studies including two citizen science efforts. Unfortunately, only the sample from Zheng et al., 2012 has demographic information. That sample is English.

Likewise, Gene 2.0 samples so far are from European American participants.

From the H & HV mtDNA Haplogroup project information, this lineage is present in Ireland, northern Scotland, and Norway. This hints that the lineage originated in one of these places. Members may have spread during the Viking era.


mtDNA Haplogroup H3k1a Phylotree History is the maternal (mtDNA) tree of humanity. It is maintained by Dr. Mannis Van Oven. Each build is a major update to the tree. The current build is #17.

mtDNA Haplogroup H3k1a Data Sources

GenBank Samples

GenBank is a database of genetic sequence data. It is run by the United States National Institute of Health. It serves as the main repository for mtDNA full sequence profiles. Samples come both from published academic literature and donations from genetic genealogy community members. In addition to GenBank samples, listings below may include other samples published but not submitted to GenBank such as those from the HapMap project.

Note: GenBank results currently use Phylotree build 16. I am working on changing resuts over to build 17.

Geno 2.0 Data

Data from Geno 2.0 is derived from the The National Geographic Society’s Genographic Project — the DAR. The Hg ID is specific to this site and is used to protect the identities of those who take part in Genographic research. Birth Country, Mother's Birth Country, and Maternal Grandmother's Birth Country have been normalized from DAR database fields. The Maternal Origin is determined based on the three previous fields.

Note: Geno 2.0 results currently use Phylotree build 16. I am working on changing resuts over to build 17.
