DNA test kits suitable for this study may be ordered from DNA Heritage, from Relative Genetics, from Genex, from Family Tree DNA, or from any other commercial service that tests Y-DNA for genealogy purposes. The collection process is as simple and non-invasive as brushing your teeth. Please check out the price comparison link to decide which best fits your budget.

A minimum test to establish probable relationship between two individuals or lineages would be 24 or more markers, but low end tests typically suffice to eliminate a relationship between individuals or lineages, and upgrades are generally available. Prices vary depending on where you order your kit, and as in so many things, you get what you pay for. The least expensive test kit may not be what you will ultimately need, and you may have to upgrade or re-test. For efficiency and cost considerations, we do not recommend that you start with an inexpensive low end test (ie, less than 20 markers) but a more comprehensive one, despite the higher initial cost.

If you purchase your test kit from one of the sites that have surname projects with member discounts associated with it, be sure to apply first to become a member of the Project to get the discount. For those who purchase test kits from sites other than DNA Heritage, please be aware we will not be automatically notified of test results. You will have to send us copies of your results in order to be included in this study.

All male Abernathy/Abernethys of any variant spelling are invited to participate, regardless of present residence or country of origin. All males whose DNA tests clearly show a close relationship to the defined groups are also included even if the surname they carry is now different, for whatever reason, known or unknown. Bernethy has been proven to be a valid variant along with the two most common spellings, Abernathy & Abernethy. Abanatha is also now a recognized variant.

Female descendants are not able to directly contribute to the project with their DNA. They can still support the project via research and by helping pay for the testing of those who are willing and able to contribute a Y-DNA sample but may not be able to afford the relatively high cost.. We have a project fund to which all interested parties can contribute. Whenever the fund surpasses the price of a full test at DNA Heritage (currently $149), then a willing candidate's test can be funded. This will hopefully increase our knowledge of the world-wide distribution of this surname and how the various branches may be related.

The project administrators are grateful for all interest and support.
