Join the The mtDNA T Project

Surnames in this Project: Our project is open to person who has already had a mtDNA test with reported result of any T haplogroup.   Participants are sought from all parts of the world.  You can participate individually, or as part of a family project with other family members sharing the cost for one or more participants representing the family line. Participants are sought from all parts of the world. We welcome participants of the National Geographic Genographic Project to join the T haplogoup project.                                                  

Project Discussion: The mtDNA information is to be used in conjunction with historical and traditional research. DNA results do not often “prove” a relationship, but can be quite helpful in guiding research. If a mtDNA profile does not match traditional genealogy, a hypothesized relationship may be incorrect.  At other times DNA results may point to an unknown adoption in the family.


What are the specifics?

  • If you were tested by Family Tree DNA, and your mtDNA test results show haplogroup T, T*, T3, T4, T5, please join our project logging into with your kit number and password. (Note: there is a separate project for T1)  On your "My FTDNA" page, click on the blue Join icon across from your name. The next page will be the Group Join page. Go to the bottom of the page to the mt Haplogroup Projects section and click on the link to the "T" projects, then click Join. There is no additional cost to join the T project. If you attempt to join this project in any other way, you may be taken to a kit ordering page. You don't need to order another kit, and there is absolutely no cost to join this project.

  • We personally recommend upgrading your test to include at least HVR1 and HVR2. If you can afford it, of course, the mitochondrial full-sequence test is ideal. This is the "Mega" mtDNA test offered by Family Tree DNA. The purpose of a Full Mitochondria Sequence test is to: a) more accurately establish the actual mutation rate of the female inherited mtDNA; b) more accurately place the female inherited DNA of all project participants on the T tree; c) apply statistics to more accurately predict when two people who match identically likely shared a MRCA (Most Recent Common Ancestor); d) allow the you and the T Project to have results that will be ‘in hand’ when more advanced scientific papers are published in the future. If you choose the mtDNA full sequence, your results will be confidential. These are the test upgrades available from Family Tree DNA: 

    • To upgrade from mtHVR1 and add HVR2,  order the mtDNA Refine test $75 
    • To upgrade from mtHVR1 to Mega (full sequence) $460
    • To upgrade from mtHVR2 to Mega (full sequence) $450


  • Participation in the project authorizes the project administrator to publish the ANCESTOR’s name, dates, locations, and the test markers on the project web pages. The project administrator will not release any personal information concerning the participant.
  • If you are interested in participating, please contact the Project Administrator listed below and submit your pedigree.


FINANCIAL CONTRIBUTIONS: Family Tree DNA has set up a donation account for the T project to help pay for testing or test upgrades of known descendants of T women. Contributions to this fund are greatly appreciated! You can designate how you want your funds to be applied. For example: "To be used for testing of descendants of Jane Smith, b. 1873 TN, married John Jones." If you would like to help, click here to make your donation. When making your contribution, specify "T" in the "Surname Project" field.  Thank you for your assistance with this important project.


GENEALOGICAL INFORMATION: Everyone is encouraged to search our Matriarchs page to find genealogical information about T ancestry. You do not have to participate in the mtDNA portion of our project to help with the family genealogies. We encourage all descendants of women who were haplogroup T to submit information about their maternal ancestors. Both males and females can add their pedigrees to our Matriarchs Page.
