A second opinion on your DNA test can help your genetic genealogy research in several ways. Your DNA Guide Diahan Southard proposes several scenarios that can help you look at your DNA test results in a new way. (Retesting may not even be necessary!)
Second Opinions on a DNA Test
“Get a second opinion.” That’s the advice we hear about our healthcare and the tactic my kids use when one parent says, “No.” But it should also be a strategy employed in our genetic genealogy pursuits.
Second opinions come in multiple varieties. You can move your DNA test results between companies. For example, while you can’t transfer into23andMe orAncestryDNA, you can transfer your autosomal DNA results out of all companies and intoFamily Tree DNA, MyHeritage, and nowLiving DNA. (Click here for step-by-step instructions.) This transfer gives you a second opinion on your ethnicity results. We have talked about how those numbers can differ between companies and your “real” values may be somewhere in between.
However, you may also want to get a second opinion for your match page. Because of different analysis methods at the various testing companies, the same match might be reported to share a different amount of DNA. Those differences should be slight, and shouldn’t influence your relationship. Remember that the amount of DNA you share is measured in centimorgans (cMs), and generally speaking, the more cMs you share, the closer your relationship. (Click hereto read more about centimorgans.)
That total amount of shared DNA can help us with another kind of second opinion. Because DNA inheritance is a random event, the amount of DNA two cousins receive from their shared 2X great grandparents can be very different. For example, according to data collected form the Shared cM Project (SCP) individuals who are documented third cousins vary widely in the amount of DNA they share. They may share as much as 253 cM but as little as 6 cM!
A Second Opinion Case Study
Let’s look at an example to see how a second opinion might be helpful in solving a genealogical mystery. In the image we see:
you
your sister
your matches Isaac and Allen
Your match Allen believes that his ancestor Mark is actually the eldest child of Jacob and Jillian. If this is the case, Allen would be your third cousin.
However, when you look at the total amount of shared DNA, you and Allen share only 48 cMs, which is below the 74 cM average for third cousins and fits better in the range of fourth cousins. Your sister is sharing slightly more, at 54 cM. So along with Allen, you begin forming a hypothesis that his ancestor Mark is actually a nephew to Jacob and Jillian, making your common ancestor either Jacob or Jillian’s parents.
However, you then get a new match in Isaac, who is a known third cousin, also a descendant of Jacob and Jillian, and you are sharing 86 cM. You then ask Isaac to tell you how many cMs he is sharing with Allen and he reports a whopping 92 cM! If we find the average amount of shared cMs between you, your sister, and Isaac and Allen, we get 65 cMs, which is much closer to the 74 cMs we would expect if you were truly 3rd cousins. In this case we could say that the genetics supports a connection between these individuals at Jacob and Jillian.
While you could still be 4th cousins instead of 3rd, having a second opinion in your sister, and then a third opinion in your known cousin can be very helpful in determining your actual relationship to Allen. Of course, the only way to know for sure if Mark is the child of Jacob and Jillian will be to find the genealogical paper trail. But in the meantime, you can continue to look for more descendants of this couple who have been DNA tested, and get a more complete picture of your genetic relationship.

YOUR DNA GUIDE: MYHERITAGE CHROMOSOME BROWSER
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.
THE NEW MYHERITAGE DNA 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.
NAVIGATING TO THE CHROMOSOME BROWSER
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.
USING THE ONE-TO-MANY 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.
THE TRIANGULATION TOOL
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.
Ready to start exploring what the MyHeritage DNA chromosome browser may tell you about your family history? You have two options.

Melissa asked about finding copyright-free music to add to family history videos. Lisa’s tips:
Unfortunately, free royalty-free music sites are few and far between.
You’re smart to be cautious because if you were to put your video on YouTube they have the technology to identify any song that is used that is a violation of copyright.
YouTube does make free music available:
Sign into YouTube with your Google account
Click on your picture in the upper right corner and go to your Creator Studio.
Upload your video (you can keep it private if you wish) and then on the video page click “Audio” (above the video title).
Choose among the many music tracks there.
Once you’ve added a track and saved it, you should be able to download the video with the music included.
The other source of music I use is music that comes with the programs I use (Animotoand Camtasia).

INTERVIEW: DONNA MOUGHTY ON IRISH RESEARCH
The following review appeared in the January 2018 newsletter of the Midwest Genealogy Center, Mid-Continent Public Library:
“If you want a quick guide on how to get started on Irish research, this short, four-page guide is an excellent resource. This guide will help you start your research in the United States, so you can figure out where in Ireland your ancestor came from. It is organized into 12 steps with helpful websites added. This guide is the first in the Irish Research Series by Donna M Moughty.”
Donna Moughty, shown left with Lisa Louise Cooke, is a professional genealogist and former Regional Manager for Apple Computers. She has been conducting family research for over 20 years. She teaches classes for beginners and lectures on a variety of subjects including Internet, Irish research, and computer topics. In addition, she provides consultations, research assistance, and training. She is a member of Association of Professional Genealogists and the Genealogical Speakers Guild.
Preparing for Success in Irish Records Research – Guide #1 (reviewed above): Without the right preparation, researching in Ireland can be frustrating! Before you jump the pond, start your research at home to determine a place in Ireland, as well as details to help differentiate your person from someone of the same name. This research guide will walk you through the process of identifying records in the US to set you up for success in your Irish research.
Irish Civil Registration and Church Records – Guide #2. Civil Registration for all of Ireland began in 1864, with Protestant marriages dating back to 1845. Even if your ancestors left before that date, they likely had relatives that remained in Ireland. Prior to Civil Registration, the only records of births (baptisms), marriages or deaths (burials) are in church records. This Reference Guide will explain how to use the new online Civil Registration records as well as how to identify the surviving church records for your ancestors in Ireland.
Land, Tax, and Estate Records – Guide #3 (NEW!). Had the Irish census records for the 19th century survived, Griffith’s Valuation, a tax list, would not be one of the most important resources for Irish researchers. Without any context, however, it can just seem like a list that includes lots of people of the same name. This Guide explains how and why Griffith’s Valuation was done, and how to use it to glean the most information about your family. Once you know your ancestor’s locality in Ireland, Griffith’s Valuation can place them on a specific piece of land between 1846 and 1864. After Griffith’s Valuation, the Revision Books allow you to follow the land and in some cases, to the 1970s, possibly identifying cousins still living on the land.

Each of the military branches is listed below, detailing information about when each was organized and resources available to genealogists on your ancestors who served in any of these branches.
United States Army. The largest of the five military branches dates back to June 14, 1775, during the early days of the Revolutionary War. Prior to the formation of the Army, each colony had companies and battalions of Associators and local militia. With the war, the need for a professional standing army to fight the British saw the formation of the Continental Army.
With the end of the Revolutionary War, the Army disbanded in 1783 after the signing of the Treaty of Paris. Later in 1796, two legions formed under the command of General Anthony Wayne would later become the nucleus of the United States Army. The Encyclopedia Britannica published this nice article on the history of the Army from its inception to the present.
A number of excellent genealogical resources are available to search for ancestors who served in the United States Army since the beginning. These databases are found on Ancestry, Fold3, and Family Search. One of the largest collections of records covers the United States Regular Army enlistments from 1798 to 1914 (available by subscription at Ancestry.com). Searching the card catalogs of Ancestry.com, Fold3and FamilySearch will yield many databases that contain information about soldiers who served, and sacrificed their lives with the Army over the last two centuries.
United States Navy. The United States Navy dates from October 13, 1775 when it was officially established by an Act passed by the Continental Congress. At the end of the Revolutionary War it was disbanded, and again reestablished under the Naval Act of 1794 which created the Navy as a permanent branch of the military.
The history of the Navy and technology can be divided into two major eras. The earlier period, called the “Old Navy,” was the age of wooden sailing ships, and still later came the birth of the ironclads during the Civil War. The later period called the “New Navy” occurred with further innovations in late nineteenth century as the United States transformed into a global power recognized the throughout the world.
The United States Navy website has a nice background history of the service. Numerous databases and searches for records of the Navy covering multiple war period detailing pensions, continental sailors, muster rolls, ships logs, and cruise books are located on Ancestry.com, Fold3and FamilySearch. Consult each database individually for records of interest.
Another organization related to the Navy is the United States Merchant Marines. Although not officially a branch of the military, the Merchant Marines sacrificed and lost lives since the days of the Revolutionary War, carrying out their missions of supply and logistics during times of war. Here’s an excellent website on the history of the Merchant Marines.
United States Air Force. The modern day Air Force dates from September 18, 1947, when it was formed as part of the Security Act of 1947. The Air Force and aviation history began under the authority of the United States Army, starting on August 1, 1907 when it was organized under the name of the Aeronautical Division of the Signal Corps. Over the next 30 years the service changed names several times:
Aviation Section of the Signal Corps (1914-1918);
Division of Military Aeronautics (1918);
Air Service of the United States Army (1918-1926);
United States Army Air Corps (1926-1941);
United States Army Air Forces (1941-1947).
In that final year, it was separated as its own organization as it is known today. Click herefor a complete history of the Air Force from 1907 to the present.
Two excellent online sources covering the early history of the Air Force from World War I and World War II are located on Fold3:
United States Marines. This elite branch of the military began with the organization of the Continental Marines on November 19, 1775. The mission of the Marines initially comprised ship-to-ship fighting, security onboard naval vessels, and assistance in landing force operations. This mission would continue to evolve over the years. At the end of the Revolutionary War, the Marines were disbanded on October 4, 1783.
Along with the Navy, under the Naval Act of 1794, the United States Marines were again re-established and would serve faithfully in every major war period and in peacetime between conflicts. The Marines will forever remain true to their motto of “Semper Fidelis” or Always Faithful as they continue to live up to their long-running tradition of honor and service. Click here to watch an interesting and accurate history of the Marine Corps is viewable online on You Tube.
Coast Guard. The history of this seagoing service dates back to August 4, 1790. Established as the Revenue Cutter Marines under the direction of Alexander Hamilton, the name was changed in 1894 to the Revenue Cutter Service until 1915. That year, an Act of Congress was passed and signed into law by President Woodrow Wilson called the “Act to Create Coast Guard.” The United States Live Saving Service and Revenue Cutter Service came together. Later, in 1939, the United States Light House Service was added to form the modern day United States Coast Guard.
The complete history of the United States Coast Guard from 1790 is on the Historians Office. It includes information about each of the separate organizations that came together to form the Coast Guard at. Ancestry.com has a collection of casualties of the Navy, Marines, and Coast Guard. Very few additional online sources are available online for this branch of the service. Researchers must access these documents and records onsite at the National Archives in Washington, DC.
Military Minutes Case Study
By Michael Strauss
Subject: Russell Strauss
Died: December 27, 1981-Jonestown, PA
Son of Harry B. Strauss & Agnes S. (Gerhart) Strauss
Over the last 30 plus years doing genealogy research, I’ve discovered that nearly all of my family members who served in the military were in the United States Army. But I have been occasionally surprised to find relatives who served in other branches of the military.
On the paternal family several years ago one of my cousins gave me a box of photographs. One of the images was marked Russell G. Strauss. He wore the uniform of the United States Navy during World War II. I recognized his name and knew that he was my grandfather’s first cousin. I was 16 years old when he died and didn’t know him very well.
His uniform indicated that he was a third class petty officer in the Navy during the war. I looked further at his uniform and noticed a diamond shaped “S” as part of the insignia. This military occupation indicated that he was a specialist that would require further research. I spoke with a couple of my older family members who knew Russell. All of my family interviewed said that he in the military police (M.P.) during the war. With additional research, I discovered that his insignia was that of the Shore Patrol. When I compared what my family said to me and his uniform told me the information matched very closely.
I found on Ancestry his application for compensation from the Commonwealth of Pennsylvania in 1950 when he served in the Shore Patrol in Norfolk, Virginia as part of his military duty (inserted below). Putting information from his photograph together with what my family members shared with me helped answer questions I had regarding of my relatives.

DNA ethnicity estimates are fun conversation-starters. But the “pie charts” become more meaningful genealogically when you can assign timelines to the places your ancestors were from. Here’s an update to our ongoing conversation about what DNA ethnicity results really mean.
Understanding DNA Ethnicity Estimates
Where did I come from? This is a fundamental human question, and it is driving millions of individuals all over the world to have their DNA tested. Now, we genealogists would like to think that they are being tested to aid their family history efforts, or to connect with us, their cousins. But they aren’t. They are after that pretty pie chart that tells them what percentage of themselves came from where.
Now, I know you have heard me say that these kinds of results are just for fun, and don’t hold much genealogical value. But due to some interesting developments in the world of DNA, my previous assertions of these ethnic origins results being somehow second class to our match list might be changing.
Living DNA and DNA Ethnicity Results
A U.K. company called Living DNA launched their DNA product in the fall of 2016. Right now, all they are focusing on is reporting ethnic origins information. But they are doing it in a manner that changes the way we look at our DNA ethnicity results.
In addition to the standard map that you will see at any genetic genealogy company, Living DNA also offers a tool they call “Through History.” It literally takes you step-by-step back in time to show you how similar your DNA is to others on earth during 11 time periods ranging from 1,000 years ago to 80,000 years ago! In the images shown below, we see a glimpse into my earliest time period, a peek at the middle, and a view of the last. The intensity of the blue on the chart tells you how genetically similar I am to the people in that area.
In the first chart shown here, you can see that since I am 100% European, I share DNA with, well, people from Europe:
But, if we go back not very far, I am sharing DNA with people in the Middle East and Russia, as shown in the second map:
As my DNA marches further back in time I can see that I am sharing that DNA with people in a variety of locations, until we get back to the beginning of man, and I am sharing DNA with literally everyone in the world.
DNA Ethnicity Estimates Over Time
So, how does this work from a DNA standpoint? Well, the fact is, not all DNA markers are created equally. Some markers have developed relatively recently in on our timeline making them helpful for determining recent relationships and modern populations. Others have been around longer, linking us to early settlers of Europe or even Asia. Still others link us together as a human race and help to track our origins back to a single time and place.
Part of the struggle that these DNA testing companies have is trying to figure out the time and place for each of the markers they test. Certainly part of the puzzle is the ability to look not just at modern day populations, but ancient populations.
You may have heard of some recent reports that scientists have completed DNA testing on ancient remains. One example came from Ireland where they were able to determine that one body tested had ancestry in the Middle East, and another had roots in Russia. It is the combined efforts of both ancient DNA testing and your own modern samples that unite to help us improve our understanding of our own personal origins, as well help us understand how humankind developed and evolved.
3 Ways to Better Understand Your DNA Ethnicity Estimates
To get the most out of your genetic genealogy populations report, you may want to:
View your results in the context of a more historical timeline, as opposed to your own genealogical timeline.
Try testing at multiple companies (you can transfer into Family Tree DNA from23andMe or AncestryDNA for only $19). Click here to see recent updates to Family Tree DNA’s ethnicity categories.
Give the multiple population tools at Gedmatch a try, just to get a better feel for how different companies and tools can provide us a different look at the populations we are carrying around in our DNA. My quick guide for using Gedmatch, shown here, is available as a printed guide or digital download.
