Best Gedmatch Test for Native American

In this article, you will learn the basics about what makes the Gedmatch admixture results different than the ones provided by your testing company in your ethnicity estimate, and which admixture calculator is the best Gedmatch test for Native American.

One of the most popular reasons for people to upload their DNA to Gedmatch is to utilize the alternative admixture calculators on the site in order to find trace Native American ancestry.

Why doesn’t my Native American ancestry show up in my ethnicity results?

I am in the planning process of an entire article dedicated to this question, but for now:

If you were expecting to find Native American ancestry in your DNA ethnicity estimate and you found none, there are two main reasons:

  • You have no Native American ancestry
  • Your 100% Native American ancestor is too far back in history to show up in your results

The less common reason, though still very possible?

  • Your Native American ancestors were not actually Native Americans by DNA (i.e. they were adopted, or descended from slaves held by Native Americans, etc)

Why are Gedmatch admixture calculators different than my Ancestry DNA or FTDNA ethnicity results?

There are two major explanations for why the Gedmatch admixture calculators give you results that are usually very different than what you will see from your testing company’s ethnicity estimate:

  • The reference samples used by the project designers are different than those used by your testing company
  • The admixture calculators are designed to “tease out” or show different aspects of your ancestry

We’ll focus on that second reason for the rest of this post:  Which Gedmatch calculator is best for “teasing” out, or showing the trace Native American ancestry that you are sure should be there?

Which is the best Gedmatch test for Native American DNA?

There are seven main admixture projects on the site, and they each focus on different aspects of ethnicity or regions of the world. 

As of yet, there is no project with a stated purpose of identifying Native American ancestry, or providing further details (such as a more specific geographic area – most calculators just say “Amerindian, or Native American, for example). 

This is really very unfortunate.  Hopefully someone will take this on as a project soon – but for now, we have to do the best we can with what we have.

With all of this in mind, there are two particular calculators on the site that I have found to help identify the trace ancestry that some of us have, and understand more about large percentages of Native American ancestry:

  • Eurogenes K36
  • MDLP World-22

Eurogenes K36 Admixture Calculator

This calculator is best used with DNA samples from people with primarily European ancestry, but it can show very small amounts of Native American.

As an example, I’d like to take a look at a test case.  The DNA sample belongs to a woman – we will call her Deedra – whose family has strong, DNA verified ties to Colonial US families. 

Based on some conversations that she overheard between her great-grandmother and other family members, she believed that her great-great grandmother had actually “buried” evidence of a Native American ancestor during her genealogy research.

Because of the rumor about a mystery Native American ancestor, this Deedra took an Ancestry DNA test.  She noticed on her ethnicity results that the amount of Native American ancestry shown was not zero, per se, but less than 1%. 

(Note:  You can no longer view percentages this low on Ancestry DNA).  After she uploaded to Gedmatch, she used the Eurogenes K36 calculator and saw the following results:

Example of Trace Native American Ancestry

I advised Deedra that a .58% Amerindian result on this calculator was not enough to confirm this trace ancestry, as an amount this low could amount to what some call statistical “noise”. 

We worked together to test her paternal grandmother, deciding not to test her father, since his father’s parents had immigrated from Holland and Germany. 

(Read about the benefit of testing more relatives)

The grandmother’s results showed more than 1.5% Native American and about .75% East Asian, which can sometimes mean Native American ancestry.  Combined with research into her family tree, Deedra was able to find a few places where there could possibly have been a Native American ancestor. 

She still has work to do to make the “paper trail” meet genealogical best practice standards.

It did come up in a discussion with her that she had been criticized for trying to find this “phantom” ancestor (implying that he/she didn’t really exist). 

Why was it so important to her to find out if she really did have a Native American ancestor? 

Deedra’s answer was two-fold (she did give me permission to talk about her results and our conversation, if you were wondering):

  • She felt offended and angry that her great-great grandmother would intentionally try to hide someone from the family tree, and she took it as a challenge to bring the ancestor to light, if it turned out to be true
  • Since all of her ancestors contributed to make her who she is, she felt it was important to be as thorough as possible in her research

Deedra jokingly mentioned, since it does come up some on a few genealogy forums, that she knows that she won’t be able to join a tribe, or call herself Native American, even if she did find out that her 6th great-grandmother was indeed an indigenous American.

In my own personal experience I have found that people tend to get involved in researching their DNA ethnicity for a variety of reasons, and we also tend to find certain aspects of our own unique family history more interesting than others.  This is completely normal.

MDLP World 22 Admixture Calculator

This DNA project is different and has a few different Native American categories – though they are very broad in geographic reach.  For someone who shows a lot of Native American ancestry, this calculator might be at least intellectually interesting. 

Take, for example, the DNA kit of someone who shows 90% Native American ancestry on Ancestry DNA:

Native American Ancestry DNA

What do the MDLP World 22 results look like for this individual?  This test taker has ancestors from the Southeast United States, Central Mexico, and possibly Central America, as well as relatively recent Irish ancestry:

example of MDLP World 22 results for someone with Native American ancestry

We found it interesting that he “matched” with what he thinks he knows about his family tree, with the only curious result being the 12.56% South America Amerindian result.  

It’s possible that he had distant ancestors who migrated from South America to Central America, where he suspects he might have had ancestors. 

Additionally, it’s possible that he just has a lot in common genetically with people who live in that area, which is relatively common for people with Native American ancestry because of generations upon generations of endogamy.

Conclusion

I hope that you enjoyed learning about my two favorite Gedmatch calculators for Native American ancestry.  If you found anything interesting or curious in your results, I would love to hear from you in the comments.

Thank you for stopping by!

Hi. As a Portuguese, with at least 4grandparents from Portugal, the last thing I expected was to get any Native American on my 23andme report. I first saw it after leaving work, on my phone. It said 0.9% Native American, I assumed it was "noise". When I got home I was able to get into a laptop and started to play with the confidence level to see at what point it would disappear. It didn't, ever. At 90% it changed from 0.9% Native American to 0.7% and then 0.2% appeared as broadly Asian and Native American. I was shocked, this was definitely the most exicting part from my whole ancestry. For a few months I kinda forgot about it, assumed that me being Portuguese and then the"Recent ancestry in the americas" showed Brazil, with 10 specific regions, and then Trinidad and Tobago so I suppose it wasn't that much out of the ordinary to have a little of Native American. Then the Coronavirus hit and with it the quarantine, I decided to take it to GedMatch and see what it had to say. I tried to be as realistic as possible, 23andme detected the Native American on my 4th chromosome, and that was the only thing I was going to trust. Well surprise, surprise! Only north and artic American detected, specifically from near the Alaska and Canada, and I also remember seing this specific name: Athabaskan. I am now more confused that ever, but eager to take this through and find out as much as I can.

Hi Joana, Thank you so much for your comment! While you did receive a very small amount of Native American DNA in your report, considering that it didn't disappear when you played with the confidence level, it is worth investigating. Were all four of your parents' parents born in Portugal? If so, you could consider that your Native American ancestry could have come from a distant ancestor with indigenous American ancestry from Brazil that ended up living in Portugal or Spain somehow. If you have even one line of your family tree that is not from Europe and has been in Brazil for several generations, or came from Brazil previously, then this is a much more likely source of indigenous ancestry. Based on your Trinidad and Tobago results and your results showing Brazil, this seems a more likely explanation. In either case, the best thing that you can do is begin building a family tree and see what records you can find. As far as the Gedmatch calculator is concerned, I wouldn't focus on the name of the population that it detected in the calculator, as indigenous Americans from both continents share a common genetic heritage. I hope that this helps!

In addition to Eurogenes K36 & MDLP World-22, I'd suggest people check out the Dodecad World9 and MDLP K11 Modern Admixture calculators, as MDLP K11 showed 1.22% Amerindian for me, and World9 showed .40% Amerindian. Considering most of the calculators on there, I don't even get any type of Native American population group percentage in my results that shows up, and just get "-", and for the World-22 one, I think I only got .12%, the fact that these other two showed quite a bit higher, if there's anything there, these ones would probably catch it. So in addition to the ones you mentioned, I think the Dodecad World9 and MDLP K11 are worth checking out.
