Anyone can Test DNA for Family History
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:
- First, it connects you to places. These are places where your ancestors came from a hundred, a thousand, or tens of thousands of years ago.
- Second, it connects you to people. These people are your genetic cousins, other living people who have taken the same DNA test that you took. The similarities in your DNA tell you that you share a common ancestor. You can then examine the pedigree of your match and work with them to help verify your family history, or give you new ideas about who your ancestors might be.
Types of DNA Tests for Family History
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.
Companies that can Test DNA for Family History
There are several companies that test DNA for family history including:
- AncestryDNA
- FamilyTreeDNA
- 23andMe
- MyHeritage
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:
- their website accessibility
- their company goals
- and especially the size of their database
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.
Great (DNA) Expectations
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!
DNA Resources
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?
Thank you

Genetic Genealogy for the Layman
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!

Mix and Match for Genetic Genealogy
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.)
Take Your DNA Test Results to the Next Level
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.
Adoption Research Success: “I Continued His Quest to Find His Birth Mother:”
Searching for birth parents? This adoption research success story involved several proven techniques: mapping DNA matches, research legwork–and years of patient determination.
Adoption Research Inspiration
This inspiring letter about adoption research came to me from Liz:
“Dear Lisa,
Thank you for your part in a major milestone of my genealogy research! You motivated me, educated me, and shared many wonderful resources throughout hours and hours of your podcasts. After listening to you talk with Diahan Southard a few times, it finally dawned on me that I should contact her to help me better understand DNA and its impact on my research.
Here’s the “story” as it unfolded for me.
During much of the last 30+ years my brother-in-law, Chuck, searched constantly for his birth mother. Chuck maintained hope that information he requested from the state of Michigan or newly available electronic adoption records might give him enough clues to help him find his mother. Six or seven years ago, Chuck was disabled by a stroke and a few years following the stroke vascular dementia robbed him of his ability to continue the search for his mother. In January 2015, we were able to get Chuck (despite the dementia) to spit in the test tube and provide a DNA sample. Little did we know he would be dead by Thanksgiving. As I wrote Chuck’s obituary, I realized I could offer one other piece of assistance to Chuck’s widow and children. I offered to continue his quest to find his birth mother.”
Then Liz outlined the steps she took to carry on the search:
“After gathering the limited detail we had (birth date, location, possible mother’s name and age) I began my research in earnest. Ultimately I:
- created a “proposed” family tree for Chuck based on Chuck’s birth mother’s surname and his birth location,
- reviewed Chuck’s DNA matches and
- began to narrow down the family tree.
I used Diahan Southard’s website tutorials as the foundation for my analysis, put together a PowerPoint presentation with my research and theory and presented the information to her in a video conference. She found no fault in my logic and helped me plan my next steps: the search for Chuck’s birth father.”
Eventually, the paper trail and the genetic research came together to tell a story:
“Last week my niece finally received the adoption records from the state of Michigan, eighty-six years after Chuck was born, over twenty years after Chuck first requested them and almost a year after his daughter requested the records. I am impatiently awaiting my copy! What I do know so far:
-
My research (thanks to you and Diahan and DNA) accurately determined the identity of Chuck’s mother.
- She had a very difficult young life and died of TB—tuberculosis – when she was just 25 years old in 1939.
- Chuck’s mother became pregnant with Chuck while a ward of the state and an Inmate at a girls school.
- Chuck’s mother became pregnant during a time when the school “farmed out” Inmates to Harper Hospital to work as nurses’ aides.
- Both Chuck’s mother and her sister checked on Chuck after turning him over to the state, both in an attempt to get him back and to learn how he was doing.
It was heartwarming to learn that Chuck actually had a birth family who cared about him! I wish he had known!”
WOW, what an incredible story! Congratulations to Liz on such thorough and persistent research. I feel very sure that Chuck knows that not only did he have a birth family that cared, but also a wonderful sister-in-law (although I would guess he well aware of that even before he passed.)
I’m also thrilled that Genealogy Gems was able to play some part in Chuck and Liz’s story.

“I Found 130 Letters by My Ancestor!” Why Use Google Books for Genealogy
Betty has at least 130 good reasons to use Google Books for genealogy! She used this powerful Google tool to find her ancestor’s name in a book–which led to a treasure trove of his original letters in an archive. Here’s what happened–and how to try this with your own family history research.
You’ve heard me say that Google Books is the tool I turn to every day. Now, you may be thinking, “But my ancestors wouldn’t be in history books!” Resist the temptation to make assumptions about sources, and about your ancestors. With over 25 million books, Google Books is more likely to have something pertinent to your genealogy research than you think. And as I often tell my audiences, those books can include source citations, providing a trail to even more treasures.
Why to Use Google Books for Genealogy: Success Story!

At the National Genealogical Society conference this past spring, Betty attended my class and then stopped by the Genealogy Gems booth to share her story. I recorded it, and here’s a transcription:
Betty: I was stuck on my Duncan Mackenzie ancestor, so I put his name in Google Books, because when you’re stuck, that’s what you do!
Lisa: Yes, I do!
Betty: So, up popped this history of Mississippi, it was sort of a specific history, and it said Duncan Mackenzie had written a letter to his brother-in-law in North Carolina from Covington County, Mississippi. And of course I already had my tax records and my census records that placed him in Covington County. This was in the 1840s. I thought, this just couldn’t be him! Why would any of my relatives be in a book? [Sound familiar?]
So, finally, weeks later, it occurred to me to go back and look at the footnotes in the book, and I found that the letters could be found in the Duncan McLarin papers at Duke University. So, I didn’t even think to even borrow the microfilm. I just told my husband, “next time you go East for work, we need to go by Duke University.” So I set up a time, and I went, and it WAS my great-great-grandfather who wrote those letters! I have now transcribed 130 letters from that collection. They let me scan them all, and I’ve been back again to scan the rest of the legal papers.
Lisa: So, an online search into Google Books not only help you find something online, but it led you to the offline gems!
Betty: And it just changed my life! Because I spend all my time on these letters. It’s distracted me from other lines! [LOL! I get that!]
How to Use Google Books for Genealogy
Are you ready to put Google Books to work in your own research and discover some genealogy gems of your own? Here, I re-create Betty’s search for you, so you can see how to get started:
1. Go to Google Books (books.google.com). Enter search terms that would pertain to your ancestor, like a name and a place.
2. Browse the search results. The first three that show up here all look promising. Click on the first one.
3. Review the text that comes up in the text screen. As you can see here, Duncan McKenzie of Covington County is mentioned–and the source note at the bottom of the page tells you that the original letter cited in the book is at Duke University.
