You’re Ready to Test?

The first step towards getting tested is to go to the Davis Surname Project webpage and request to join the Project by clicking “Join Request” on the top menu. The cost for the test is cheaper if you are in a surname project. The administrator will contact you with a web link  and a code to enable you to order the test at the reduced price.

After you read “About this group” and “DNA FAQ,” if you have any questions you can contact the administrator of the Davis Surname Project:

Basically, you then go to the FTDNA (Family Tree DNA) site and sign up for the test and they will send you a vial. You send it back with a swab of saliva from your mouth and 6 weeks later they will send you an email saying that the first section of the results have been posted. The results come back in stages.

The DNA test is just a swab of the inside of the mouth. The saliva sample is only used for genealogical purposes. The results are posted by kit #, not name, on the Davis Surname Project website, where they can be matched to others.

If you go to the FTDNA Davis Surname Project page (slow to load), you will see our Davis subgroup (shaded dark brown), “Davis, William, K87577 .” The DNA of the 29 or more Davis men on the chart all match closely, all I-L160,  and so we are able to conclude that we are all descendants of Rev. William Davis, born 1663. Many of the men on the chart have a paper history of their family so those who don’t know where they fit can check the known trees to get a better idea of where to do their searching.

Prices can change frequently. Best to check with FTDNA for current cost of tests.

If you want some basic information about how the DNA tests work and what some of the nomenclature means, you can visit, Internatl Society of Genetic Genealogy, and read their section: “For Newbies.”


We recommend the 67 marker test. The larger test is more exact and may help pinpoint which family line you most closely match. But you can start out with one of the smaller tests and then upgrade to the larger.

The 12-marker test can be used to rule out a match or to find out if you are a probable match to William Davis’ DNA. The majority of testers who match the first 12 markers of William Davis’ I2a1b haplogroup usually match in the later markers. If you match the first 12 markers, then you could test further.

Update: the Autosomal Test can be taken by males or females. It will give you DNA matches and ethnic percentages.

Let me know if you have any questions about this procedure. If you decide to test, please contact me with your line so I can see where you fit on the Davis family tree and can add you to our charts.

Let me know when you take the test and I will keep an eye out for your results. I am happy to help anyone who tests. I will answer any questions and help translate the results when they come in.

Looking forward to finding the connections between us all,
