From Diahan Southard, Your DNA Guide here at Genealogy Gems: DNA testing is one of the most personal ways to get involved in your family history. You have DNA from your parents, who have DNA from their parents, and so it goes, back into your greats and great-greats. The technology of genetic genealogy is all about tapping into that DNA record and pulling out information that might be useful in your family history. DNA can do this for you in two ways:
You have three choices of DNA tests, each with its own unique purpose.
YDNA – Essentially, if you want to know about a male ancestor, you need to find a direct male descendant to be tested. So if I want to know about my 3X great grandfather Morris Mitchell, I need to find Morris’s son’s son’s son, etc. until I find a living male with the Mitchell surname who can be tested on the Y chromosome DNA (mtDNA) test at Family Tree DNA.
mtDNA – If I want to know about a female ancestor, let’s say Mary West, I need to find Mary’s daughter’s daughter’s daughter’s etc. child (male or female) to take the mitochondrial DNA (mtDNA) from Family Tree DNA.
Autosomal DNA – For any ancestor, male or female, who is fewer than 5 generations from you, you can take the autosomal DNA test at either Family Tree DNA, AncestryDNA, 23andMe, or MyHeritage to find out more about that individual. Remember with the autosomal DNA that you always want to test the oldest generation first. So anyone who does not have both of their parents living should take the autosomal DNA test.
There are several companies that test DNA for family history including:
Each of these companies is offering a very similar kind of test, but each has their own unique tools and databases. Decide which company you want to test with by evaluating things like:
You can see a table comparing these companies here. The MyHeritage test is new, and is not on the chart yet, but will be soon.
The best thing you can do when setting out on your genetic genealogy journey is set good expectations. You can expect that the test will document the personal genetics of the person who takes it. By so doing, you are creating another genealogy record that will last for generations. This test will link you to your ancestors via your cousins. That means that you may take the test looking for ancestors, but what you get are cousins. It will take traditional genealogy work to turn those cousin connections into ancestral connections. Above all, expect that this is a growing industry, and what we know today is different than what we will know tomorrow, so enjoy the journey!
There are several comprehensive books on Genetic Genealogy out there. However, for the layman who just wants to understand their DNA test results and get some additional value from them, an entire book full of scientific explanations can be overwhelming and daunting. The following email is one we receive regularly:
Could you direct me to an understandable publication which explains DNA results in layman’ terms?
From Lisa Louise Cooke, host of The Genealogy Gems Podcast: I put myself in the category of “layman” when it comes to understanding DNA test results. And that’s why when I met DNA expert Diahan Southard at a genealogy conference, I immediately invited her to join Genealogy Gems. Diahan’s enthusiasm is contagious, and her ability to explain genetic genealogy to the layman is second to none!
Here’s a link to our DNA videos on YouTube with the author of the guides, Diahan Southard. As you will see, she has a ton of enthusiasm for helping the layman understand and get the most out of their DNA!
The beauty of the DNA quick reference guide series is that you can mix and match the guides to perfectly suit the testing you have done. We’ve published Diahan’s guides that delve into the testing companies FamilyTreeDNA and 23andMe, as well as the other tests available such as Mitochondrial (for your maternal line – both men and women can take this test) and YDNA (for your paternal line – only men take this test.)
If you’ve already tested and feel like you have a good foundation, then I highly recommend Diahan’s Advanced DNA Bundle. It will take your DNA test results to the next level by instructing you on the heart of what matters in plain English.

(This interview has been slightly edited for clarity)
Lisa: What is DNA painter?
Blaine: DNA Painter is a really incredible website for genealogists working with their DNA results.
There are several different aspects of the website, including chromosome mapping, which is assigning segments of DNA to particular ancestors. There are some tools for testing hypotheses, like What Are the Odds. And there’s also the Shared Centimorgan Project, which allows you to hypothesize what a genealogical relationship to a match might be based on the amount of DNA you share with that match.
Lisa: As I understand it, that’s kind of how you got involved with DNA painter, or how DNA painter evolved. Tell us a little bit about your background and your work with the Shared cM Tool.
Blaine: I have been a genetic genealogist, essentially, for almost 20 years now. I started in 2003 with my first DNA test and I’ve been a genealogist since middle school. So, I’ve been working in this DNA field for a long time.
Once autosomal DNA testing came along, we discovered that there wasn’t a lot of information about known ranges for various relationships. For example, if I test myself in a first cousin, how much DNA would we share? What might be considered a normal amount? What might be an abnormal amount, and so on? So, I started in 2015 collecting data from test takers, for example, sets of first cousins. We wanted to be able to answer questions like what’s your relationship? And how much DNA do you share? Once I started to collect enough of that data, I could get an idea about what the range for various relationships might be.
Johnny Pearl, the incredible creator behind DNA painter, asked if he could host a version of the Shared Centimorgan Project at the website. I was thrilled to see that. And so now there is a hosted version of the Shared Centimorgan Project with all of those ranges for about 40 different relationships at a DNA Painter.
Lisa: Well, that’s really kind of the whole industry, isn’t it? It’s very collaborative. And it’s amazing how it seems like different people have different pieces of the puzzle.
Is DNA Painter free? How does someone get involved? Do we need an account?
Blaine: It depends on what you want to do. If you want to use the Shared Centimorgan Project tool, there’s no cost for that. That’s free for anyone to use. So, you would just go to DNA Painter, and either register for a free account, or have no account and still be able to use the Shared Centimorgan Tool.
If you want to start chromosome mapping at DNA Painter, you do get one free map. That’s the assignment of those segments to ancestors. But if you wanted to have maybe a couple maps, you would have to run into having a subscription to the site, which is well worth the money it takes to have a subscription because it’s so valuable in helping you organize your matches and working with your segment information, and so on.
Lisa: You mentioned the chromosome mapping, and the Shared Centimorgan Tool, and What Are the Odds? Can you give us an example of a burning question that a genealogist might have, and that the answer is, “you need to go to DNA painter to do that”?
Blaine: So, let’s say for example, you get a new match at testing company ABC, and that match shares 400 Centimorgans with you. The immediate question is, how is this person related to me? That’s a lot of DNA to share with someone but without a frame of reference you don’t really know. Is it could that my eighth cousin? Is it my sibling? What are the possible relationships?
If you go to DNA Painter and the Shared Centimorgan Project, you pop in 400 Centimorgans. What that’s going to do is it’s going to give you the possible relationships that that could be. And so that’s going to significantly narrow down your search for your genealogical relationship to this new DNA match that you have.
Lisa: Oh, yeah, that would be huge.
So, does this require much technical know-how? Do people have to feel like they’re scientific in nature, or can anybody do this? Could a person new to using genetic genealogy feel like they could do this?
Blaine: Absolutely! And I think one of the great things about DNA Painter and Johnny is that everything is designed to be user-friendly. The website is incredibly easy to understand and interact with the Shared Centimorgan Project. I’m of course biased, but I think it is also created in such a way to be easily understandable. The results of that search for 400 centimorgan relationships is going to give you an output that I think is easy to interpret and understand.
Lisa: What’s your favorite tip? What do you recommend that people either not miss, or make sure that they do while they are at DNA Painter?
Blaine: Bookmarking the Shared Centimorgan Project I think is really important. I think many genealogists use it on a daily basis. Again, I’m biased, but the value of the tool is that it’s free. And it’s so important to helping you understand the possible relationships for your DNA matches.
Now, years from now, once you do this enough, you can start to remember some of the ranges. You can kind of do it in your head. But until you get to that stage, bookmark that site, and you can just refer to it quickly when you’re working with your DNA results.
Lisa: That’s a good idea. It’s very easy to just drag that URL right on to your web browser bookmark bar and have a bookmark ready to go.
You’ve really been on the forefront of all of this genetic genealogy. And I know that you’re the author of a book, tell us the name of your book.
Blaine: The name of my book is the Family Tree Guide to DNA Testing and Genetic Genealogy, second edition.
Lisa: What do you think we can look forward to in the future of genetic genealogy?
Blaine: I think it’s really hard to predict in some ways. Some of the tools we have now are our tools we couldn’t even have imagined several years ago. And what’s fueling this growth is the growth of the databases themselves.
For example, just in the past week or so Ancestry came out with a new tool called Side View that allows the grouping of your matches into the two different sides of your family: your paternal side and your maternal side. We couldn’t have imagined a tool like that just a couple of years ago, but it’s because of the size of the database.
For me, the future is two-fold. Number one, it’s the development of these new tools by the testing companies. And it’s also development of new tools by third parties, including the tools like the Shared Centimorgan Project, DNA Painter, and so on. I think we’re going to see more and more tools come out that allow us to work with our results in new and interesting ways.
Lisa: Do you think they’ll ever be a time where the tools and the machine learning that eventually there’s enough data accumulated between people who have tested and people who do genealogy and people who do both, that it could actually automate this process?
Blaine: I do think there’s a huge potential for automation. The one thing that I think is missing right now is that most genetic genealogists, most genealogists period, function as islands. And there isn’t enough collaboration in a way that allows us to benefit from each other’s work. And so, I think there needs to be a way to start to tie together in a more collaborative way, the work that we’ve done. For example, assigning segments of DNA to ancestors.
If I figure out that this stretch of DNA came from Jane and John Doe, that’s great, but that lives on my computer. If there were a way to share that with the world in an easy and collaborative way by clicking a couple of buttons, then, once we have thousands of people doing that, we could have a pretty incredible database and start to really work in a collaborative fashion.
Lisa: Collaboration certainly has been the key behind so much of what’s grown in genealogy.
Blaine, thank you so much for all of your work in this area. It’s fascinating to watch what you’ve been up to and I’m going to keep my eyes on you into the future. Please tell folks where they can visit you to learn more about you and what you have to offer.
Blaine: The two main places are thegeneticgenealogist.com, which is my blog. If you’re a Facebook user, we have Genetic Genealogy Tips and Techniques, which is a Facebook group. It’s free to join, and from beginner to expert, everybody I think has a really good time in that Facebook group.
Lisa: It’s always good to see you. Thank you so much, Blaine!
Blaine: Thank you so much.

Do you have a DNA problem?
Maybe it’s as simple as having a ton of matches and not knowing what to do with them. How do you keep track of all those matches. How to you know which matches to focus on? How can you can use all your matches to do what you really want to do, which is learn more about my family history?
In this episode of Elevenses with Lisa we are visiting with someone who has worked past many of those problems. She uses her DNA matches to solve some of her genealogical questions and the questions of her patrons. Today she’s here to help you!
My special guest is Sara Allen, a librarian at the Genealogy Center at the Allen County Public Library. I wanted to talk to Sara because she’s not a biologist, or a Genetic Genealogy Guru. She’s like you and me: she’s passionate about family history! She shares genetic genealogy with folks in a very practical, and easy-to-understand way.
As a side note, we were lucky to record this episode because the day Sara and I were to meet to record the library was closed due to a snow storm. I’m in Texas and we’re buried in a deep freeze with devastating power outages, and at our house, no water for a time. But we moved things around and got it done. However, in all the chaos I managed to put my microphone on the wrong setting, so I’m going to sound like I’m sitting in a Folgers coffee can. But that doesn’t matter because it is what Sara has to say that’s really important.
Oh, and they were also doing construction at the library the day we finally recorded, so it’ll sound occasionally like we use jack hammers on our DNA! However, neither snow nor ice nor lack of water nor construction zones will keep us (as your faithful genealogists) from the swift completion of this appointed show.
Special Guest: Sara Allen, Librarian, Genealogy Center at Allen County Public Library, Fort Wayne, IN
Sara shared her basic over-arching plan for using DNA to answer a genealogical question:
Then she shared the specific steps for her research plan.
Step 3 was to choose the most relevant DNA test. This is important because there are three main kinds of tests out there. Each has strengths and weaknesses. Understanding what each test is capable of is key to getting the results you need.
If you’ve decided that an Autosomal DNA test is what you need, a relative one or two generations older (on the correct side of the family) is always better. Examples: Parents, Aunts/Uncles, Grandparents, Great-aunts/uncles, Parent’s first cousin
If you’re going to do a Y or mtDNA, choose a family member who falls within the correct path of DNA inheritance.
If there is a family tree, copy it, either electronically or print it out on paper. Compare and contrast trees looking for common names, common ancestor couples, common places. Work on establishing relationship between the different matches based on their trees. In other words, do genealogy!
Here’s an outline of the case Sara covers in this episode so you can follow along.
Dovey Reynolds was born around 1822 in North Carolina and was married in 1846 in Owen County, Indiana to Phillip Allen. She died in 1901 in Jefferson County, Kansas. No records have been found naming her parents.
Autosomal DNA – test the closest living person to the mystery ancestor: Test my father or his sister (aunt) to get one generation closer.
Step 5: Complete Family Tree for Other Family Lines
Results of our search for “Reynolds” in matches’ trees: Look for Reynolds in key locations in Dovey’s life such as NC and IN, especially Owen Co. IN, and maybe KS:
24 matches to William Reynolds’ descendants (27 cM – 8 cM)
Granddaughter Kathy took the autosomal DNA test.
Ancestry DNA match sorting options:
Evaluated trees of the possible matches from Leroy’s side. Two match groups identified:
Can we find a marriage between these 2 families? Yes – Daniel Hedges married Alice Crute ca. 1894 probably Warren Co. PA.

Just last year, if you had asked me if I thought anyone could catch AncestryDNA in their race to own the genetic genealogy market, I would have been skeptical. However, it is clear that MyHeritage intends to be a contender, and they are quickly ramping up their efforts to gain market share and your confidence.
MyHeritage began 2018 by making a much-needed change to their DNA matching algorithm, which had some errors in it. They were able to adjust it, and now it is humming right along, telling our second cousins from our fourth. Another development, launched in February, is the addition of a Chromosome Browser.
Much like you would browse the library shelves for the perfect book, or browse through the sale rack for a great bargain, you can use a Chromosome Browser to look through your chromosomes for the pieces of DNA you share with your genetic cousins.
Chromosome Browsers can be everything from a fun way to review your genetic genealogy results, to a tool to assist in determining how you are related to someone else. Let’s go over three tips to help you make use of this new tool.
There are actually two different kinds of Chromosome Browsers in MyHeritage: one to view only the segments you share with one match (the One-to-One Browser), and a browser where you can see the segments shared with multiple matches (the One-to-Many Browser).
To get to the One-to-One Browser, head over to your match page and find a cousin for whom you would like to see your shared DNA segments. Click on Review DNA Match, then scroll down past all the individual match information, past the Shared Matches and Shared Ethnicities until you see the Chromosome Browser.
To find the One-to-Many Chromosome Browser, you can use the main DNA navigation menu at the top of the MyHeritage homepage. Click on DNA, then on Chromosome Browser, as shown below.
In the One-to-Many Chromosome Browser you can compare yourself, or any account you manage, to anyone else in your match page. To choose a match to evaluate, just click on their name and they will be added to the queue at the top, as shown here.
Clicking on Compare will then allow you to see the actual segments you share with each person:
In this One-To-Many view, each individual match gets their own line for each chromosome. Since we have added 7 people to the Chromosome Browser, there are seven lines next to each chromosome number. Each match not only gets their own line, but also their own color. So you can easily match up the lines on the chromosome to the match that shares that piece of DNA with you. For the majority of people the majority of the time, these Chromosome Browsers are just another fun way to visualize the connection you have with your DNA match. In the end, it doesn’t matter where you are sharing on the chromosome, just how much DNA you are sharing. You can obtain that information from your main match page and never look at this Chromosome Browser image, and still make fantastic genetic genealogy discoveries.
Another feature of the Chromosome Browser on MyHeritage is the Triangulation tool. To understand how this works, you first need to understand that you actually have two copies of each chromosome. Two copies of chromosome 1, two copies of chromosome 2, etc. One copy is from mom, and the other from dad. However, in the Chromosome Browser image, you see only one line for yourself (in grey). Therefore, when you see someone matching you on chromosome 14, for example, you don’t know if that person is matching you on the chromosome 14 you got from your mom, or the chromosome 14 you got from your dad.
Likewise, if you see two people whose shared piece with you looks to be in the same location on the same chromosome, you can’t tell if they are both sharing on the same copy of that chromosome, or if one match is related to your dad’s family, and the other match is related to your mom’s family. However, this is what the Triangulation tool does for us. It tells us if two (or three or four, etc.) matches are sharing on the same copy of the same chromosome. Be careful when you use this tool, though. Many erroneously assume that when they see a segment shared between multiple people, that indicates the presence of a recent common ancestor for all of those people. However, that is not always the case.
MyHeritage.com is the place to make connections with relatives overseas, particularly with those who may still live in your ancestral homeland. Click here to see what MyHeritage can do for you: it’s free to get started.

MyHeritage DNA is new on the scene of genetic genealogy. With the recent launch of their DNA Matching, I decided to give it a test drive for you. I have now uploaded my test results from another company. Follow along as I share what I like about the MyHeritage DNA site…maybe it is just what you’ve been looking for!There is no question that the launch of MyHeritage DNA fully into the genetic genealogy market is exciting news. We absolutely need someone to challenge AncestryDNA. Competition is good.
In September, MyHeritage began to provide matching results for individuals who had uploaded their test results from another company to their site. As of today, uploading your DNA test results to MyHeritage DNA is still free, so if you have been thinking about it, you may want to take advantage sooner rather than later. As expected, the matches are only as good as the depth of the database, and it is early in the game. Their DNA database is small, but even now we can get an idea of what to expect from MyHeritage as they take their first steps into genetic genealogy.
One of the most exciting elements of their November 7, 2016 announcement is their development of a Founder Population project where they have hand-picked individuals to represent their reference population for calculating ethnicity. They plan to launch with 25 population groups, but will likely increase to 100 in a fairly short amount of time. This is a far more advanced ethnicity report than is currently offered anywhere else.
After you have figured out how to download your raw data from your testing company (see my instructions here: http://www.yourdnaguide.com/transferring), and add it to MyHeritage (you have to add a family tree to MyHeritage to do this), you will need to wait the requisite time to process. Then, you will receive an email notice that you have new DNA matches:
You can access DNA matches when you log on to the site: under Discoveries, click DNA Matches (as shown below).
As for my favorite features, I like how they list all the possible relationships that make sense between you and your match, taking into account multiple factors like your age, gender, and your genetics instead of a simple, generic range like 2nd-4th buy chlamydia medication uk cousins. The accompanying chart, which visually shows you all possible relationships, is also very helpful. You can access the chart by clicking on the little question mark icon next to the relationship suggestions.
I like that these suggestions remind us that our genetic relationships have different genealogical interpretations. Meaning that genetically, a 2nd-cousin-once-removed, a first-cousin-twice-removed, and a second-cousin, all fall within a similar genetic range and it is impossible to determine your exact relationship based on the genetics alone.
I also like how MyHeritage offers all three genetic descriptors of your relationship:
While this is more of an intermediate to advanced piece to your results, it can be important as your relationship analysis becomes more involved.
MyHeritage makes a unique claim in their press release about their matching feature addressing a main concern genetic genealogists have: the lack of pedigree information provided by their matches. MyHeritage claims that 95% of their DNA samples have pedigrees attached. That is remarkable! However, from my own quick calculation of my matches, the number with pedigrees is more like 60%.
They also indicated that they will soon be doing a bit of pedigree-analysis for you by providing a list of shared surnames and locations between you and your match. This will be based on the pedigrees you have both submitted and will certainly be a welcome addition.
According to their November 9th Q and A, MyHeritage hasn’t decided yet if the ethnicity features will be available to those who only transfer, and they hint at many more features they have in the works that may only be offered to those who purchase their test.
In short, the MyHeritage DNA site is currently functioning much like the top three genetic genealogy sites (Ancestry, Family Tree DNA, and 23andMe) and like the free tool Gedmatch: it offers a meeting place for those who have been tested at one company to meet those who have tested at another.
