Here’s the latest DNA update quoted from Ancestry®:
Ancestry® Expands Reference Panel to Deliver More Precise Results and New Regions
“Today, Ancestry® announced their latest update to AncestryDNA® ethnicity estimates.
This update was made possible thanks to an increase in the AncestryDNA reference panel.
The reference panel is now more than double its previous size with samples from more places around the world, allowing Ancestry to determine ethnic breakdowns with a higher degree of precision.
New ethnicity estimates will roll out to new and existing customers over several months, resulting in these potential developments for customers.”
New Ethnicity Regions
From their blog post:
“For example, previously we had North and South America as two large regions: Native American–Andean and Native American–North, Central, South.
With this new update, we are able to refine the areas into 11 smaller ones.
If you received one of the older regions before, your new report will most likely have one of the newer, more precise regions instead like Indigenous Eastern South America, Indigenous Cuba, and Indigenous Americas–Mexico, among others.”
More Global Regions
“This advancement will enable AncestryDNA to deliver even more regions globally to enhance the experience across diverse populations including improvements and region realignment in West Africa, northwestern Europe, the Americas, Oceania, and South Asia.”
When You Will See the Update
“It’s important to note that we are phasing the update over time to ensure individual attention is given to delivering each result; therefore, some may see results earlier or later than others.”

List of AncestryDNA® Regions
“More than 1,000 global regions make up the ethnicities displayed in our DNA test. As DNA science improves, the number of regions we test for (and the countries covered in each region) may change.
This article lists each region, but to see which areas of the globe are included in the regions, you’ll need to view the list from your DNA Story page (which will highlight an area of the map when you click a region).
To see all the regions, click See other regions tested at the bottom of your ethnicity estimate and click on a region on the next page.

(Update 2020) When genealogists take an ancestry DNA test, they are looking for more than just their ethnicity results. They are also very interested in receiving information on other people who have tested who closely genetically match them. They want to know who the closest matches are, and if those matches have family tree information that they can share.
However, with all the people testing these days, (some being genealogists and some not) the volume of matches can become overwhelming very quickly.
Are you one of those people who have way too many genetic “4th cousins or closer” among your DNA matches? Have you ever wondered “What do I do with all these matches?!” If so, keep reading. We’re going to explore some of your options, and most importantly, how to determine how genetically close your cousins really are.
Doing the DNA Math on Your Cousins
Math can provide us with a degree of certainty in genetic genealogy. Each of us has two biological parents. We have four biological grandparents, and eight great-grandparents.
However, the farther back we go the less we can rely on math.
For example, on paper you should have sixty-four 3rd great grandparents. However, many of us find that the same person occupies more than one slot on our pedigree chart. While this significantly decreases the workload for traditional genealogy, it adversely impacts your genetic genealogy. Especially when it comes to that long long list of 4th cousins you have in your match list at any of the three major DNA testing companies.
Depending on how intermarried your lines are, you may be seeing individuals on your match list that genetically look like your fourth cousins, but they are genealogically your sixth cousins – EIGHT TIMES! So how can you tell the difference?
There are two parts to that answer: one you can control, and the other you can’t.
Distinguishing DNA Matches with Genetic Tools
While your fourth cousins and your eight-time-sixth cousins may look similar genetically, there are often small clues in the genetics that can help you tell the difference. This distinction can sometimes be detected by a testing company who, through research and validation, has been able to fine-tune their algorithms to detect these subtle differences.
Your Genetic 4th Cousins
You can participate in this double checking process by using some of the genetic tools that are available to you at Family Tree DNA, or at Gedmatch.com. But since you may not be an aspiring geneticist, let’s focus on the genealogical work you can do to determine if a match is truly a fourth cousin.
Use Google Earth to Plot Your DNA Matches
A fourth cousin designation just means that you and your match are separated by between six and twelve degrees (people). So that might be five back on your chart to your common ancestor, and five down to your match, which would make you true fourth cousins. It could also be some other permutation of that.
For our example, let’s assume true fourth cousins. That means that the two of you share one of thirty-two 3rd great grandparents (16 couples). In order to find out which set, you have two genealogical identifiers: surname and location.
Therefore, the first thing you should do is make a list of the surnames and locations of those thirty-two 3X great grandparents.
Now, most of us do not know all 16 of those couples, so you are going to have some holes. Feel free to fill in those holes with surnames on subsequent generations that will carry through to this fifth generation.
A great tool to plot your own list of ancestors geographically is the free downloadable Google Earth software.
Check to see if you have the latest version of Google Earth downloaded to your desktop or laptop computer. On your desktop, look for a grey and white globe. If you see a blue and white globe, you have the older original free version of Google Earth. However, a few years ago, Google made their Google Earth Pro version free to everyone, and it is now the standard.
If you do have Google Earth Pro (the grey globe software) then you’re ready to go.
The grey Google Earth globe on the desktop.
If you don’t have it, then you will need to download it.
How to Download the Free Google Earth Software:
- Go to http://www.google.com/earth/download/gep/agree.html
- Click the blue download button
- Read the Terms and Conditions
- If you agree to them, click the Agree and Download button
- Follow the installation guide
- When complete click Run Google Earth
Now that you have Google Earth, you can begin by creating a folder in the Places panel in Google Earth devoted to your 16 couples. Here’s how:
1. In the Places panel, right-click on MyPlaces and select Add > Folder:
Right-click on MyPlaces > Add > Folder
2. Name the folder and then click OK:
Creating a folder in Google Earth
3. Now you will see your new DNA folder for your 16 couples in the Places panel. If you don’t see it, look toward the bottom of the list. You can move the folder to any location within the list by dragging and dropping it.
Create a folder in Google Earth for DNA 16 couples
Once you have your DNA folder created fro your 16 couples, you can then easily plot your surnames and locations.
How to Plot Your Surnames and Locations in Google Earth:
1. Click your new DNA folder to select it. This will ensure that the placemark you are about to create will be stored in that folder.
2. In the search box (upper left corner of the Google Earth software) type in the first location and click Search. Google Earth will fly to that location on the map.
Type the locaton in the Search box and click Search.
3. In the toolbar along the top of the screen, click the placemark button to place a pushpin in that location:
Click the Placemark button in the Google Earth toolbar.
4. In the Placemark dialogue box, enter a title for hte pushpin placemark. Click the OK button to close the box and set your placemark.
5. Repeat the process for all the locations.
Then evaluate the fifth generation of your fourth cousin matches for genealogical information that lines up with any of the items on your list.
You can also plot the surnames and locations of your matches in Google Earth. This is where Google Earth really comes in handy. The free software makes it very easy to see when your ancestral home may be bordering the locations of your matches. Those with whom you find a similarity become your best matches, and your best chance of determining your connection. Those without an obvious connection cycle to the bottom of your pile for a genetic evaluation. You can perform these same kinds of searches for your second and third cousins as well.
As you begin to become more familiar with the fifth generations of your matches, you may also start to see patterns of surnames or locations emerge among your matches. These then become the surnames and locations that might be able to fill the missing spaces in your pedigree chart.
