Tate YDNA Project

About us

 This genetic genealogy project is designed to bring together researchers with the surname Tate and its variant spellings -- Tate/Tait//Taitson/Teat/etc -- by focusing on Y-DNA matching of males. Women should submit samples of their male relatives for testing. 

It is recommended that members get at least a 37-marker Y-DNA test to match against other members' results. A 67-marker test is more costly, but better for those who are close matches and has proven useful in determining branching within a family, haplogroup origins, and the approximate number of generations to a common ancestor. The 111-marker test is even more costly, but is most applicable to very close matches and haplogroup projects focusing on ancient origins. 

Discounted prices for DNA tests are occasionally available during the year. Discounts are also available to new members of the project by using the Join button at the top of the page. Project members will be notified when discounts are being offered.

To help build knowledge of the various Tate lines, each member should provide information about their earliest known Tate male ancestor, such as their name, birth & death dates and locations, wives' names, along with information about your line of descent from that ancestor, although you should not include information about living individuals. This information will help determine if test results and pedigrees indicate similarity of family lines with other members and if you have a known or potential common ancestor with them.

Because DNA results may differ slightly from your ancestors due to natural mutations, project members should be aware that a mutation on one or more markers can occur in just one generation. Some experts have stated that a mutation in closely related individuals occurs approximately every three generations, or roughly every 100 years. Thus, a one unit mutation on two markers (that is, a genetic distance of 2) would indicate 6 generations or approximately 200 years back to a common ancestor. However multiple mutations can also occur in just one generation, so care in interpreting results is advised.

The main table in the project shows the more common STR (short tandem repeat) results, while another shows the more advanced SNP (single nucleotide polymorphism) results. Menus along the side of the page provide access to the tables, pedigrees/lineages, and other information.

You can access this site through your personal FTDNA page or use the link below for direct access.



Those with non-Tate Y-DNA results, but who have a Tate elsewhere in their lineage, should examine the project's data, such as the pedigrees and the groupings in the results tables, to see if it can help define their particular line. 

Non-Tate Y-DNA results are not included in the project's results tables since they do not apply to the project's goals. 


Anyone having an interest in their deep ancestry and wanting to better understand their ancestors' origins are encouraged to submit a sample for

FTDNA's definitive deep clade Y-DNA test called "Big Y700", which is rather expensive, although substantial discounts are made available about twice each year. 

Full genome Y-DNA testing, which is more expensive, but more extensive, is available from http://www.fullgenomes.com, YSEQ.net, and others.

Other Y-DNA tests, such as single SNPs and multi-SNP panels, can help determine near-terminal SNPs at lower cost, but must be selectively chosen.


Project administrators are not genetics or genealogy experts, but have an interest in both areas based on our own personal research and experience. We encourage interaction between members of the project to advance individual and combined research interests.
