The Treadwell/Tredwell DNA Project is for Treadwell / Tredwell family members to work together to learn more about our common heritage through DNA testing and sharing of information. Male Treadwells are invited to join and add their yDNA results to the project. All variant spellings are welcome. If your Surname spelling is missing, we'll be glad to add it. The webpage is public and you do not need to be a member to view the results of testing.
