our current project status as of November 2019 is:

We now have four participants, two men and two women. Two from the Hannah Hamilton maternal line of descent; one from each daughter. Two from the Hannah Hosmer Hayward maternal line of descent; one from each daughter.

Each has a matching Haplogroup: K2a6, a very recently developed group, less than 5,000 years old. Only about 4 percent of women carry it.

Each has exact matching HVR1 mutations

Each has exact matching HVR2 mutations

Three have exact matching Coding Region mutations (one has a single Heteroplasmy event, which is a mutation in progress and is considered a match)

One has a single Coding Region mutation difference out of the over 16,000 locations identified.

This mt-DNA project now serves as a very strong indication that our living descendants have a common female ancestor. Combined with the paper trail research, it is very strongly indicated that that common ancestor is Hannah Hosmer Hayward whose daughter Hannah, b. 1670 in Concord, MA married John Hamilton, the Yeoman of Concord.
