85 African
American regions

Trace your African American heritage even deeper through history by finding your connection to regions and stories as far back as the 1700s.

92 regions now
in Ireland

If your family story leads back to the shores of the Emerald Isle, you’re in luck, as it now boasts close to 100 regions—37 in Munster, alone.

62 regions now
in Mexico

Get an even clearer picture of your Mexican origins, from the Yucatan Peninsula all the way up into New Mexico and southern Texas.

Even in the relatively tight quarters of this Caribbean island, the detail is extraordinary, with the smallest region covering only a 10-mile radius.

As AncestryDNA® grows, so do the possibilities.

We’re able to provide this level of detail thanks to our patented technology, powered by our unique combination of the world's largest consumer DNA database and the largest network of family trees. We’re always working to improve your results to give you the best possible experience.

AncestryDNA® More Detail Than Ever

Frequently asked questions about our next-generation ethnicity estimate.

  • If you have one of these new regions, you’ll find them in a separate section at the bottom of your ethnicity results, or nested beneath a larger region. These regions do not have a percentage assigned to them and are marked by a circle surrounded by a dotted line. These regions are found using our patented Genetics Communities™ technology, where we analyze genetic connections between groups of AncestryDNA members, and use public family trees, ethnicity data, and historical records to determine where this group of people lived over time. Over 500 of our regions have been identified this way. These groups identify areas where your ancestors may have lived more recently, anywhere from 1700-1925.
  • Your ethnicity estimate includes regions based on two different scientific processes: the AncestryDNA reference panel and Genetic Communities™.
    The current release is for African American regions within the US and the Caribbean and is based on the second technology (What we call Genetic Communities). This technology relies on there being many customers whose ancestors are from a specific part of the world and at least some of them having extensive family trees. It is not possible at this time to include these types of regions within most of Africa.
    The current regions within Africa were uncovered using the technology that uses the AncestryDNA reference panel. When we next update our reference panel and/or the technology behind defining these regions, there may be additional African regions added.
  • Your ethnicity estimate includes regions based on two different scientific processes: the AncestryDNA reference panel and Genetic Communities™.
    The AncestryDNA reference panel is made up of people who have long-standing, documented roots in a specific area. We compare your DNA to this reference panel to determine your possible origins ancestry hundreds to more than a thousand years ago. Regions with a solid circle in your results are based on the reference panel. These regions also have percentages assigned to them.
    The Genetic Communities™ process detects groups of AncestryDNA members who are most likely connected because they share recent ancestors who came from the same region (such as Ulster Irish) or culture (such as Mormon Pioneers). Through the Genetic Communities process, we analyze genetic connections between groups of AncestryDNA members. We then use public family trees, ethnicity data, and historical records to determine where this group of people lived over time. Over 500 of our regions have been identified this way. These groups identify areas where your ancestors may have lived more recently. Regions with a dotted circle are based on Genetic Communities. These regions do not have a percentage assigned to them.
  • With this update, you might lose one of the regions found either just under the regions with percentages or in the “Additional Communities” section at the bottom. Most customers who have lost a region will find that it has been replaced with a new, smaller region. With this release, we’ve broken many larger regions into smaller ones.
    Sometimes people lose a region without a replacement. This usually happens when the confidence score for one of these regions was previously low. You can see how strong your link to a region is by clicking on the region and then clicking the information icon to the right of the region name. There you will see one of three categories: possible, likely, or very likely. Most people who lose a region will lose a possible region.
    The number of samples in our database has grown since we first released these types of regions. This additional data allowed us to find hundreds of new regions, but it also refined how we classified who should be in these regions. Based on these new classifiers, some people whose link to one of these regions was already low may lose that region in their updated AncestryDNA results.
  • Your results may change in the future for a couple of reasons. First, because our Genetics Communities™ technology is new, cutting-edge science, it is constantly being updated and refined. As we update how we identify and define these regions, your results may change. Second, as we add more and more customers to our AncestryDNA database, we hope to increase the number and granularity of the regions we offer. This means that in the future, you may be added to new regions or to a newly refined region.
