HOW TO JOIN Page

Surnames in this Project: Our project is open to any male with the Thompson surname or to any man believing that he is descended in the paternal line from a Thompson or other surname variant (see below). 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 Thompson DNA Project.   

Surname Variants: Cavish, Combie, Combs, Comish, Coombs, Holmes, Macash, Macavish, Macawis, MacCaish, MacCash, Maccause, MacCavish, MacCaws, MacChombich, MacComaidh, MacComb, MacCombe, MacCombich, MacCombie, MacCombs, MacCome, MacComie, MacComish, MacComy, MacHomas, Macomb, Macomie, Macomish, MacTavish, MacThom, MacThomaidh, MacThomais, MacThomas, MacTomais, Makcawis, Makcaws, MaKcome, M'Avish, M'Awishe, M'Cauish, M'Cavis, M'Cavish, McAwis, McChomay, McColm, McColme, McComas, McComb, McCombe, McCombie, McCome, McComie, McComish, McKawes, M'Colmy, M'Combie, M'Comie, McThomas, M'Homie, M'Thomas, M'Thomie, Tamblyn, Tamesone, Taminson, Tamlin, Tamlyn, Tamplin, Tams, Tamson, Tamzen, Tamzin, Taplin, Tapling, Tappin, Tapping, Tapson, Taweson, Tawesson, Thom, Thomalin, Thomas, Thomasin, Thomason, Thomasset, Thomassin, Thomasson, Thomazin, Thomerson, Thomes, Thomeson, Thomessone, Thomkins, Thomlin, Thomling, Thomlins, Thomlinson, Thomlyn, Thompkins, Thompsen, Thompsett, Thompson, Thoms, Thomsen, Thomsett, Thomson, Thomsone, Thomsoun, Tolmin, Tolming, Tolson, Tomblin, Tomblinson, Tombs, Tomes, Tomkies, Tomkin, Tomkins, Tomkinson, Tomlin, Tomlins, Tomlinson, Tomlyn, Tompkin, Tompkins, Tompsett, Tompson, Toms, Tomsett, Tomson, Toombs, Toulmin, Toulson, Towenson, Towerson, Towlason, Towlinson, Towlison, Towlson, Townson, Towson                                            

How DNA testing works: The DNA results of one person tell us nothing about our ancestors because we don't have the ancestor's DNA to compare. It is only by finding current DNA matches and comparing genealogies that we can determine our ancestors' DNA markers and our common ancestry. DNA information must be used with traditional historical and genealogical research.

DNA results can help prove and disprove relationships, and are especially useful in guiding research. If a DNA profile matches others with the same genealogy, a hypothesized relationship may be correct.  At other times, DNA results may point to an unknown adoption in the family or to some other so-called "non-paternity event."

For the Thompson DNA Project, we test the Y-chromosome which is passed from father to son. Since a Surname Project traces members of a family who share a common surname, the tested individual must be a male who wants to check his paternal line (father's father's father's...). Females don't carry their father's Y-chromosome, so they should look for a brother or cousin with the Thompson surname to be tested. Females can also help with the Thompson genealogies (see below), and they can contribute to our Sponsorship Fund to help male Thompsons in their line to participate.

How do I do the test?

  • The first option is testing with Family Tree DNA, of Houston TX, the leading testing company for Surname DNA Projects. The cost per participant is dependent on the number of markers tested, but all tests include an estimate of the Haplogroup (an indication of deep ancestry). We personally recommend the largest number of markers that you can afford.  We expect that most serious researchers will eventually upgrade to 37 markers even if they don't start there. You will only need a 67-marker test if you find a close match and want to further refine the results. Either the 25 or 37 marker test can be useful in identifying other families that share a common ancestor. It is highly likely that a 12 marker test will ultimately require an upgrade, so we recommend the 12 marker test only for those who are sponsoring other families in search of a match to their own family or those who cannot afford a 25 marker test. 

    • 67 marker test $269

    • 37 marker test $189

    • 25 marker test is $148

    • 12 marker screening test is $99 

    • Add $2 for US postage and $4 for international postage

  • Family Tree DNA will store your sample for 25 years, unless you request them to destroy it.

  • The test is a simple cheek swab.  The kit will arrive and leave your house by mail.  You simply rub the inside of your cheek a number of times with a special scraper, put the kit back into the envelope, and put it in the mail.
  • Participation in the project authorizes the project administrators to publish the ANCESTORís name, dates, locations, and the test markers on the project web pages. The project administrators will not release any personal information concerning the participant.
  • If you are interested in participating, please contact one of the Project Administrators listed below and submit your pedigree.

  • A second option is testing with DNA Heritage which uses the Sorenson Genomics laboratory. DNA Heritage will test individual markers at $5.99 per marker, but there is a minimum of 23 markers ($137.77). A full-panel test of 43 markers is $189. Thirty-four (34) of these markers are also tested at Family Tree DNA. Please note that DNA Heritage is currently offering a special price on DNA testing. DNA Heritage uses the markers reported by the Sorenson Molecular Genealogy Foundation, so they can be used for finding matches in its database at http://smgf.org.

  • DNA Heritage will automatically destroy your sample after six months. This testing company is not recommended if you might not be able to get another sample from the participant!

  • The test is a simple cheek swab.  The kit will arrive and leave your house by mail.  You simply rub the inside of your cheek a number of times with the swabs provided, put the kit back into the envelope, and put it in the mail.

  • Participation in the project authorizes the project administrators to publish the ANCESTORís name, dates, locations, and the test markers on the project web pages. The project administrators will not release any personal information concerning the participant.

  • If you are interested in participating, please contact one of the Project Administrators listed below and submit your pedigree.

 

GENEALOGICAL INFORMATION: Everyone is encouraged to search our Patriarchs page to find genealogical information about Thompson ancestry. You do not have to participate in the DNA portion of our project to help with the Thompson genealogies. We encourage all descendants to submit information about their Thompson ancestors. Both males and females can add their Thompson pedigrees to our Patriarchs Page.

We also seek volunteers with genealogical expertise to help verify, document, and extend the pedigrees.
