About us

This is a Y-DNA-only project. Please do not request to join unless your account has a Family Tree DNA Y-DNA test.

--------------------------------------------------------------------------------------------------------------------------------------------------

A concentration of Johnston families in Counties Tyrone and Fermanagh reveals two different Y-DNA haplogroups: I-M223 and R-M269, with a few much smaller Y-DNA haplogroups. Our geographic scope includes Johnston families of Fermanagh, Tyrone, Donegal, Armagh, Down and adjacent counties.

--------------------------------------------------------------------------------------------------------------------------------------------------

The project uses a Johnston Research Group e-mail discussion for all communications. You will be joined to the Johnston Research Group e-mail list if you are approved to join the project.


All who join this project should also join the North of Ireland DNA Project (https://www.familytreedna.com/groups/nifhs/about).

Haplogroup I-M223 Johnstons should also join the Johnstons of Annandale Project (https://www.familytreedna.com/groups/johnsto-nof-annandale/about).
