MyHeritage LIVE – T-Minus 41 Days and Coupon

I’m getting really excited about MyHeritage LIVE 2019 in Amsterdam in just 41 days. I wrote about the conference and speakers, here. You won’t be disappointed!

I’ve been wanting to make a short video in the garden to experiment and see how well videos worked. MyHeritage gave me the perfect reason when they sent a registration coupon to save 10% that I can share with you.

If you’re planning to attend and need to purchase a ticket, there are a few seats still available and MyHeritage would like to fill them. Plus, Amsterdam is a wonderful city and there’s so much to do!

Let me tell you about why I’m so excited about Amsterdam!

Ok, I need a selfie stick, maybe some video training and practice:) The message is what’s important, right?!!

To utilize the coupon, just visit the MyHeritage LIVE site here and register, using code Roberta10.

You’re welcome!

There has been some discussion about having a short meetup of blog followers. The conference isn’t huge, and I’ll be there for the entire time so I’m sure that we will be able to chat over breakfast, lunch, dinner, a snack break or drinks in the pub. (Have you tried Ginger Joes? It’s a European ginger beer and it’s absolutely amazing!)

One of the great things about MyHeritage LIVE is that it’s very friendly and communal. Visiting with other genealogists is one of the best parts.

I can hardly wait!

And, ummm, did I mention the party….

If you haven’t yet purchased a DNA kit or transferred one from elsewhere, there’s still time to do that too, but I’d hurry.

I sure hope to see you there! We’re going to have a wonderful time!

MyHeritage Updates Theories of Family Relativity

If you have taken a MyHeritage DNA test or transferred there, quick, check your results because you may have new Theories of Family Relativity! I do.

MyHeritage theory update.png

MyHeritage introduced Theory of Family Relativity for their DNA customers in February this year at RootsTech. I wrote about the introduction and how to use and evaluate Theories here.

Theories of Family Relativity, sometimes abbreviated as TOFR, first looks at your DNA matches, then their trees, and provides you with theories as to how you share a common ancestor.

These are called theories for a reason. They utilize your tree and other people’s as well. Sometimes multiple trees have to be used to connect the dots if you or your matches tree isn’t extended far enough back in time.

My normal cautions about trees apply here. One of the great things about theories, though, is that if there are different “paths” suggested by trees, TOFR shows those multiple paths and allows you to evaluate for yourself.

Evaluation is crucial – which is why they are called theories.

Multiple DataBases Contribute to Increased Theories

MyHeritage utilizes trees and other information from multiple databases and then ranks their probability of being accurate. Databases include:

  1. MyHeritage records
  2. 45 million trees at MyHeritage
  3. FamilySearch trees
  4. Geni trees

In their blog article, MyHeritage provides additional details such as:

  • The total number of Theories has increased from 6 to 14 million
  • More than 46% of their users have at least one Theory (no tree, no Theory)
  • A new notification system is being rolled out, so you’ll receive an e-mail when you receive new Theories
  • For now, the TOFR database will be updated periodically, but eventually it will be automated so that TOFRs will be reported as they occur

My Theories

In February, I had 51 Theories. This week, MyHeritage refreshed TOFR again and now I have 26 more for a total of 77.

Of these new 26, 24 are accurate. One connects me to the wrong son of my ancestor, and one is inaccurate – but I know why both are wrong.

The second inaccurate theory is because most trees include the wrong mother for my ancestor Phoebe Crumley. Her mother was Lydia Brown, not Elizabeth Johnson. I performed extensive research, including mitochondrial DNA testing, and proved that Phoebe’s mother was Lydia, not Elizabeth. However, wrong trees are plentiful and have been propagating like weeds for years now in many databases with no documentation.

This is why evaluation is critical.

I particularly like that theories aren’t just provided blindly, expecting you to just have faith, but each “link” is evaluated and given a confidence ranking.

Using Theories

He’s an example of how to use theories. You can find them by clicking on the purple View Theories banner or under DNA matches by utilizing the Tree Details filter.

MyHeritage example theory.png

If you have a new Theory, it will be labeled as such so you don’t waste time looking at Theories you’ve already processed. I write a note for every match I’ve reviewed in the notes box in the upper right hand corner.

MyHeritage new theory.png

Theories are important, but don’t overlook the information in the green box. If the theory turns out to be not exactly correct – the additional information may still be the link you need.

View the theory by clicking on either the View Theory link or the Review DNA Match button. Your theory is the first thing you’ll see below the match itself.

MyHeritage view full theory.png

The theory is presented with the detail available when you click on View full theory.

In this example, my first cousin tested and entered at least a partial tree. TOFR created 5 different “paths” based on combinations of trees as to how we are related.

MyHeritage review match.png

I’m displaying Path 3 where the link has a 93% confidence ranking. To view that comparison, click on the green intersection button and additional information between the two trees used to create the theory will display. In this case, it’s me with no additional information, but Path 1, below, shows the link between two trees at our common grandfather level.

MyHeritage green intersection.png

Now if I click on the green intersection button, I see a lot more information, based on the information in both trees, shown side by side comparatively. The more information in the trees, the more information MyHeritage has to use when constructing these Theories.

MyHeritage match detail.png

I love this tool!

Even my Theories that aren’t completely correct provide me with hints and other people’s information to evaluate. I can almost always figure the rest out by myself.

Better yet, given that I paint my matches with known ancestors at DNAPainter, I now have 26 more matches to paint, AND, if I look at my shared matches with these people, I’m sure I’ll have even more. I may never surface for air!

Many people are very likely to discover new ancestors, especially people who are newer to genealogy!

Beware though, and verify, because these connections are hints and theories, not gospel.

How Do You Get Theories?

Maybe you don’t have Theories and want some. How can you encourage the system to generate Theories?

MyHeritage DNA person card.png

  • If your DNA is not attached to your person card, connect it by clicking on the DNA tab at the top of any page, then on Manage DNA Kits.

MyHeritage manage DNA kits.png

  • Under Manage DNA Kits, you’ll see 3 dots to the right side. Click there to assign a DNA kit to a person.

MyHeritage assign DNA kit.png

  • You must have a tree, even if it’s a small tree. The more robust your tree, the more Theories you are likely to have because MyHeritage can make those connections. For example, if your tree has only you plus your parents, other trees much have you or your parents in their trees too in order for MyHeritage to be able to connect the dots. Enter as many ancestors as you can into your tree. You can build your tree at MyHeritage or you can upload a GEDCOM file.
  • When MyHeritage offers Smart Matches between a person in your tree and a person in another user’s tree, confirm the Smart Match if it’s accurate. Smart Matching is one of the tools that MyHeritage can utilize to confirm that two people in different trees are actually the same person. You can do three things with Smart Matches.
  1. Confirm the match without doing anything else which does not import any information from the other person’s tree.
  2. Confirm, at which time you will be given the option to import field by field, if you so choose.
  3. Under the Confirm box, click the dropdown and select “Save to Tree” which imports everything from the other person’s tree for that match into your tree. I do NOT recommend this option, certainly not without reviewing what they have in their tree and their sources.
  • Prepare and Wait – After testing or uploading your DNA, work with your matches and Smart Matches to extend your tree so that you’ll be in a prime position to receive Theories of Family Relativity as soon as it’s run again. Soon, it will be automated and running continuously.

Getting Started

If you want to play, you have to test or transfer. Here’s how:

Have fun!!!

DNA Results – First Glances at Ethnicity and Matching!

People who have worked with genetic genealogy for a long time often forget what it’s like to be a new person taking a DNA test.

Recently, someone asked me what a tester actually sees after they take a DNA test and their results are ready. Good question, especially for someone trying to decide what might work for them.

I’m going to make this answer very simple. For each of the 4 major vendors, I’m going to show what a customer sees when they first sign in and view their results. Not everything or every tool, just their main page along with the initial matching and ethnicity pages.

Please feel free to share this article with people who are new and might be interested. It’s easy to follow along.

I do want to stress that this is just the beginning, not the end game and that every vendor has much more to offer if you take advantage of their tools.

Best of all, it’s so much FUN to learn about your heritage and your ancestry, plus meeting cousins and family members you may not have known that you had.

I’ve been gifted with photos of my grandparents and great-grandparents that I had no idea existed before meeting new family members.

I hope that all the new testers will become excited and that their results are just a tiny first step!

The Vendors

I’m going to take a look at:

Each vendor offers DNA matching to others in their database, plus ethnicity estimates. Yes, ethnicity is only an estimate.

Family Tree DNA

Family Tree DNA was the first and still the only genetic genealogy testing company to offer a full range of DNA testing products, launching in the year 2000. Today they stand out as the “science company,” offering both Y and mitochondrial DNA testing in addition to their Family Finder test which is comparable with the tests offered by Ancestry, 23andMe and MyHeritage.

Your personal page at Family Tree DNA shows the following tools for the Family Finder test.

Glances Family Tree DNA home

The two options we’ll look at today are your Matches and myOrigins, which is your ethnicity estimate.

Click on Matches to view whose DNA matches you. In my case, on the page below, you can see that I have a total of 4610 matches, of which 986 have been assigned to my paternal side, 842 to my maternal side, and 4 to both sides. In my case, the 4 assigned to both sides are my children and grandchildren, which makes perfect sense,

Glances Family Tree DNA matches

You can click to enlarge this graphic.

The green box above the matches indicates additional tools which provide information such as who I match in common with another person. I can see, for example, who I match in common with a first cousin which is very helpful in determining which ancestor those matches are related through.

The red box and circle show information provided to me about each match.

Family Tree DNA is able to divide my matches into “Maternal,” “Paternal” and “Both” buckets because they encourage me to link DNA matches on my tree. This means that I connect my mother to her location on my tree so that Family Tree DNA knows that people that match Mother and me both are related on my mother’s side of the tree.

Your matches don’t have to be your parents for linking to work. The more people you link, the more matches Family Tree DNA can put into buckets for you, especially if your parents aren’t available to test. Plus, your aunts and uncles inherited parts of your grandparent’s DNA that your parents didn’t, so they are super important!

Figuring out which side your matches come from, and which ancestor is first step in genetic genealogy!

You can see, above, that my mother is “assigned” on my maternal side and my son matches me on both.

“Bucketing” is a great, innovative feature. But there’s more.

The tan rounded rectangle includes ancestral surnames, with the ones that you and your match have in common shown in bold.

Based on the amount of DNA that I share with a match, and other scientific calculations, a relationship range is calculated, with the linked relationship reflecting where I’ve put that person on my tree.

If your match has uploaded or created a tree, you can view their tree (if they share) by clicking on the little blue pedigree icon, above, circled in tan between the two arrows.

Glances Family Tree DNA tree

Here’s my tree with my family members who have DNA tested attached in the proper places in my tree. Of course, there are a lot more connected people that I’m not showing in this view.

Advanced features include tools like a matching matrix and a chromosome browser where you can view the segments that actually match.

Family Tree DNA Ethnicity

To view your ethnicity estimate, click on myOrigins and you’ll see the following, along with people you match in the various regions if they have given permission for that information to be shared with their matches:

Glances Family Tree DNA myOrigins

MyHeritage

MyHeritage has penetrated the European market quite well, so if your ancestors are from the US or Europe, MyHeritage is a wonderful resource. They offer both DNA testing and records via subscription, combining genetic matches and genealogical records into a powerful tool.

Glances MyHeritage home

At MyHeritage, when you sign in, the DNA tab is at the top.

Clicking on DNA Matches shows you the following match list:

Glances MyHeritage matches

To review all of the information provided for each match, meaning who they match in common with you, their ancestral surnames, their tree and matching details, you’ll click on “Review DNA Match.”

MyHeritage provides a special tool called Theories of Family Relativity which connects you with others and your common ancestors. In essence, MyHeritage uses DNA, trees and records to weave together at least some of your family lines, quite accurately.

Here’s a simple example where MyHeritage has figured out that one of the testers is my niece and has drawn our connection for us.

Theory match 2

Theories of Family Relativity is a recently released world-class tool, easy to use but can solve very complex problems. I wrote about it here.

Advanced DNA tools include a chromosome browser and triangulation, a feature which shows you when three people match on a common segment, indicating genetically that you all 3 share a common ancestor from whom you inherited that common piece of DNA.

MyHeritage Ethnicity

To view your ethnicity estimate at MyHeritage, simply click on Ethnicity Estimate on the menu.

Glances MyHeritage ethnicity.png

23andMe

23andMe is better known for their health offering, although they were the first commercial company to offer autosomal commercial testing. However, they don’t support trees, which for genealogists are essential. Furthermore, they limit the number of your matches to your 2000 closest matches, but if some of those people don’t choose to be included in matching, they are subtracted from your 2000 total allowed. Due to this, I have only 1501 matches, far fewer matches at 23andMe than at any of the other vendors.

Glances 23andMe home

At 23andMe when you sign on, under the Ancestry tab you’ll see DNA Relatives which are your matches and Ancestry Composition which is your ethnicity estimate.

Glances 23andMe matches

While you don’t see all of the information on this primary DNA page that you do with the other vendors, with the unfortunate exception of trees, it’s there, just not on the initial display.

23andMe also provides some advanced tools such as a chromosome browser and triangulation.

23andMe Ethnicity

What 23andMe does exceptionally well is ethnicity estimates.

To view your ethnicity at 23andMe, click on Ancestry Composition.

Glances 23andMe ethnicity

23andMe refines your ethnicity estimates if your parents have tested and shows you a composite of your ethnicity with your matches. However, I consider their ethnicity painting of your chromosomes to be their best feature.

Glances 23andMe chromosome painting

You can see, in my case, the two Native American segments on chromosomes 1 and 2, subsequently proven to be accurate via documentation along with Y and mitochondrial DNA tests at Family Tree DNA. The two chromosomes shown don’t equate necessarily to maternal and paternal.

I can download this information into a spreadsheet, meaning that I can then compare matches at other companies to these ethnicity segments on my mother’s side. If my matches share these segments, they too descend from our common Native American ancestor. How cool is that!!!

Ancestry

Ancestry’s claim to fame is that they have the largest DNA database for autosomal results. Because of that, you’ll have more matches at Ancestry, but if you’re a genealogist or someone seeking an unknown family member, the match you NEED might just be found in one of the other databases, so don’t assume you can simply test at one company and find everything you need.

You don’t know what you don’t know.

Glances Ancestry home

At Ancestry, when you sign on, you’ll see the DNA tab. Click on DNA Story.

Glances Ancestry DNA tab

Scrolling past some advertising, you’ll see DNA Story, which is your Ethnicity Estimate and DNA Matches.

ThruLines, at right, is a tool similar to MyHeritage’s Theories of Family Relativity, but not nearly as accurate. However, Thrulines are better than they were when first released in February. I wrote about ThruLines here.

Glances Ancestry matches

Clicking on DNA Matches shows me information about my matches, in red, their trees or lack thereof in green, and information I can enter including ways to group my matches, in tan.

One of Ancestry’s best features is the green leaf, at the bottom in the green box, accompanied by the smiley face (that I added.) That means that this match’s tree indicates that we have a common ancestor. However, the smiley face is immediately followed by the sad face when I noticed the little lock, which means their tree is private and they aren’t sharing it with me.

If DNA testers forget and don’t connect their tree to their DNA results, you’ll see “unlinked tree.”

Like other vendors, Ancestry offers other tools as well, including the ability to define your own colored tags. You can see that I’ve tagged the matches at far right in the gold box with the little colored dots. I was able to define those dots and they have meanings such as common ancestor identified, messaged, etc.

Ancestry Ethnicity

To view your ethnicity estimate, click on “View Your DNA Story.”

Glances Ancestry ethnicity

You’ll see your ethnicity estimate and communities of matches that Ancestry has defined. By clicking on the community, you can see the ancestors in your tree that plot on the map into that community, along with a timeline. Seeing a community doesn’t necessarily mean your ancestor lived there, but that you match a group of people who are from that community.

Sharing Information

You might be thinking to yourself that it would be a lot easier if you could just test at one vendor and share the results in the other databases. Sometimes you can.

There is a central open repository at GedMatch, but clearly not everyone uploads there, so you still need to be in the various vendors’ data bases. GedMatch doesn’t offer testing, but offers additional tools, flexibility and open access not provided by the testing vendors.

Of these four vendors, Family Tree DNA and MyHeritage accept transferred files from other vendors, while Ancestry and 23andMe do not.

Transferring

If you’re interested in transferring, meaning downloading your results from one vendor and uploading to another, I wrote a series of how-to transfer articles here:

Enjoy your new matches and have fun!

Identifying Unknown Parents and Individuals Using DNA Matching

There have been a lot of questions recently about the methodology used by people searching for unknown parents and other unidentified individuals. I covered this technique in concept recently at a conference as part of an overview presentation. In this article, I’m addressing only this topic and in more detail.

What is the methodology that genealogists use to identify unknown parents? It’s exactly the same process used to identify unknown Does, meaning unidentified bodies as well as violent criminals who have left DNA, such as blood or semen, at a crime scene.

How is Identifying Unknown Individuals Different from Genealogy?

Genealogists are interested in discovering their ancestors. Generally, genealogists know who their parents are and most of the time, their grandparents as well. Not very many people can tell you the names of their great-grandparents off the top of their head – not unless they ARE genealogists😊

Genealogists interview family members and access family sources, such as photos, Bibles, boxes of memorabilia and often extend their family another generation or two using these resources. Then, to gather additional information, genealogists turn to publicly available sources such as:

Constructing a Tree

Genealogists utilize software to create trees of their ancestors, either on their own computers with software such as Family Tree Maker, Legacy, RootsMagic or the free tree building software from MyHeritage. They then either synchronize or duplicate their tree on the public sites mentioned above which provide functionality such as “hints” that point to documents relevant to the ancestors in their tree. Additionally, they can access the trees of other genealogists who are researching the same ancestors. This facilitates the continued growth of their tree by adding ancestors and extending the tree back generations.

While tree-building is the goal of genealogists, the trees they build are important tools for people seeking to identify unknown individuals.

The Tree

Generations tree

In my tree, shown in the format of a pedigree chart, above, you can see that I’ve identified all 16 of my great-great-grandparents. In reality, because I’ve been a genealogist for decades, I’ve identified many more of my ancestors which are reflected in my tree on my computer and in my trees at both Ancestry and MyHeritage where I benefit from hints and DNA matches.

Genealogical pedigree charts are typically represented with the “home person,” me, in this case at the base with my ancestors branching out behind them like a lovely peacock’s tail.

While I’m looking for distant ancestors, adoptees and others seeking the identities of contemporary people are not looking back generations, but seek to identify contemporary generations, meaning people who are alive or lived very recently, typically within a generation.

Enter the world of genetics and DNA matching.

Genetics, The Game Changing Tool

Before the days of DNA testing, adoptees could only hope that someone knew the identify of their biological parents, or that their biological parents registered with a reunion site, or that their court records could be opened.

DNA testing changed all of that, because people can now DNA test and find their close relatives. As more people test, the better the odds of actually having a parent or sibling match, or perhaps a close relative like an aunt, uncle or first cousin. My closest relative that has tested that I didn’t know was testing is my half-sister’s daughter.

You share grandparents with your first cousin, and since you only have 4 grandparents, it’s not terribly difficult to figure out which set of grandparents you connect to through that first cousin – especially given the size of the databases and the number of matches that people have today.

The chart below shows my matches as of June 2019.

Vendor

Total Matches

Second Cousin or Closer

Family Tree DNA

4,609

18

MyHeritage

9,644

14

23andMe

1,501

5

Ancestry

80,151

8

You can see that I have a total of 45 close matches, although some of those matches are duplicates of each other. However, each database has some people that are only in that database and have not tested at other companies or transferred to other databases.

Situations like this are exactly why people who are searching for unknown family members take DNA tests at all 4 of the vendors.

Stories were once surprising about people who tested and either discover a previously unknown close relative, or conversely discovered that they are not related to someone who they initially believed they were. Today these occurrences are commonplace.

Matches

If you’re searching for an unknown parent or close relative, you just might be lucky to receive a parental, sibling, half-sibling or uncle/aunt match immediately.

An estimated relationship range is provided by all vendors based on the amount of DNA that the tester shares with their match.

Generations Family Tree DNA matches

My mother’s match page at Family Tree DNA is shown above. You can see that I’m Mother’s closest match. My known half brother did not test before he passed away, and mother’s parents are long deceased, so my mother should NEVER have another match this close.

So, who is that person in row 2 that is also predicted to be a mother or daughter? I took a test at Ancestry and uploaded my results to Family Tree DNA for research purposes, so this is actually my own second kit, but for example purposes, I’ve renamed myself “Example Adoptee.” Judging from the photo here, apparently my “adopted” sibling was a twin😊

If the adoptee tested at Family Tree DNA, she would immediately see a sibling match (me) and a parent match (Mom.) A match at that cM (centiMorgan) level can only be a parent or a child, and the adoptee knows whether she has a child or not.

Let’s look at a more distant example, which is probably more “typical” than immediately finding a parent match.

Let’s say that the “male adoptee” at the bottom in the red box is also searching for his birth family. He matches my mother at the 2nd-3rd cousin level, so someplace in her tree are his ancestors too.

People who have trees are shown with gold boxes around the tiny pedigree icons, because they literally are trees of gold.

Because of Family Tree DNA’s “bucketing” tool, the software has already told my Mother that the male adoptee is a match on her father’s side of her tree. The adoptee can click on the little pedigree icon to view the trees of his matches to view their ancestors, then engage in what is known as “tree triangulation” with his other close matches.

From the Perspective of the Adoptee

An adoptee tests not knowing anything about their ancestors.

Generations adoptee

When their results come back, the adoptee, in the red box in the center, hoping to identify their biological parents, discovers that their closest matches are the testers in the pink and blue ovals.

The adoptee does NOT know that these people are related to each other at this point, only that these 7 people are their closest matches on their match list.

The adoptee has to put the rest of the story together like a puzzle.

Who Matches Each Other?

In our scenario, test takers 2, 3 and 8 don’t match the adoptee, so the adoptee will never know they tested and vice versa. Everyone at a second cousin level will match each other, but only some people will match at more distant relationships, according to statistics published by 23andMe:

Relationship Level

Percentage of People Who Match

Parents, siblings, aunts, uncles, half siblings, half aunts/uncles and 1st cousins

100%

2nd cousins

>99%

3rd cousins

90%

4th cousins

45%

5th cousins

15%

6th cousins and more distant

<5%

You can view a detailed chart with additional relationships here.

Tree Triangulation

By looking at the individual trees of test taker 1, 4 and 5 whom they match, the adoptee notices that John and Jane Doe are common ancestors in the trees of all 3 test takers. The adoptee may also use “in common with” tools provided by each vendor to see who they match “in common with” another tester. In this case, let’s say that test taker 1, 4 and 5 also match each other, so the adoptee would also make note of that, inferring correctly that they are members of the same family.

The goal is to identify a common ancestor of a group of matches in order to construct the ancestor’s tree, not a pedigree chart backwards in time, as with genealogy, but to construct a descendants’ tree from the ancestral couple to the current day, as completely as possible. After all, the goal is to identify the parent of the adoptee who descends from the common ancestor.

Generations adoptee theory

In this case, the adoptee realized that the pink test takers descended from John and Jane Doe, and the blue test takers descended from Walter and Winnie Smith, and constructed descendant trees of both couples.

The adoptee created a theory, based on the descendants of these two ancestral couples, incorporating other known facts, such as the year when the adoptee was born, and where.

In our example, the adoptee discovered that John and Jane Doe had another daughter, Juanita, whose descendants don’t appear to have tested, and that Juanita had a daughter who was in the right place at the right time to potentially be the mother of the adoptee.

Conversely, Walter and Winnie Smith had a son whose descendants also appear to have not tested, and he had a son who lived in the same place as Juanita Doe. In other words, age, opportunity and process of elimination all play a role in addition to DNA matches. DNA is only the first hint that must be followed up by additional research.

At this point, if the adoptee has taken either Y or mitochondrial DNA testing, those results can serve to either include or exclude some candidates at Family Tree DNA. For example, if the adoptee was a male and matched the Y DNA of the Smith line, that would be HUGE hint.

From this point on, an adoptee can either wait for more people to test or can contact their matches hoping that the matches will have information and be helpful. Keep in mind that all the adoptee has is a theory at this point and they are looking to refine their theory or create a new one and then to help narrow their list of parent candidates.

Fortunately, there are tools and processes to help.

What Are the Odds?

One helpful tool to do this is the WATO, What Are the Odds statistical probability tools at DNAPainter.

Using WATO, you create a hypothesis tree as to how the person whose connection you are seeking might be related, plugging them in to different tree locations, as shown below.

Generations WATO

This is not the same example as Smith and Doe, above, but a real family puzzle being worked on by my cousin. Names are blurred for privacy, of course.

Generations WATO2

WATO then provides a statistical analysis of the various options, with only one of the above hypothesis being potentially viable based on the level of DNA matching for the various hypothetical relationships.

DNAPainter Shared cM Tool

If your eyes are glazing over right about now with all of these numbers flying around, you’re not alone.

I’ll distill this process into individual steps to help you understand how this works, and why, starting with another tool provided by DNAPainter, the Shared cM tool that helps you calculate the most likely relationship with another person.

The more closely related you are to a person, the more DNA you will share with them.

DNAPainter has implemented this tool based on the results of Blaine Bettinger’s Shared cM Project where you can enter the amount of DNA that you share with someone to determine the “best fit” relationship, on average, plus the range of expected shared DNA.

Generations DNAPainter Shared cM Project

You, or the test taker, are in the middle and the relationship ranges surround “you.”

For example, you can clearly see that the number of cMs for my Example Adoptee at 3384 is clearly in the Parent or Child range. But wait, it could also be at the very highest end of a half sibling relationship. Other lower cM matches are less specific, so another feature of the DNAPainter tool is a life-saver.

At the top of the page, you can enter the number of matching cMs and the tool will predict the most likely results, based on probability.

Generations 3384

The relationship for 3384 cMs is 100% a parent/child relationship, shown above, but the sibling box is highlighted below because 3384 is the very highest value in the range. This seems to be a slight glitch in the tool. We can summarize by saying that it would be extremely, extremely rare for a 3384 cM match to be a full sibling instead of a parent or child. Hen’s teeth rare.

Generations parent child

Next, let’s look at 226 cM, for our male adoptee which produces the following results:

Generations 226

The following chart graphically shows the possible relationships. The “male adoptee” is actually Mom’s second cousin. This tool is quite accurate.

Generations 226 chart

Now that you’ve seen the tools in action, let’s take a look at the rest of the process.

The Steps to Success

The single biggest predictor of success identifying an unknown person is the number of close matches. Without relatively close matches, the process gets very difficult quickly.

What constitutes a close match and how many close matches do adoptees generally have to work with?

If an adoptee matches someone at a 2nd or 3rd cousin level, what does that really mean to them?

I’ve created the following charts to answer these questions. By the way, this information is relevant to everyone, not just adoptees.

In the chart below, you can view different relationships in the blue legs of the chart descending from the common ancestral couple.

In this example, “You” and the “Other Tester” match at the 4th cousin level sharing 35 cM of DNA. If you look “up” the tree a generation, you can see that the parents of the testers match at the 3rd cousin level and share 74 cM of DNA, the grandparents of the testers match at the 2nd cousin level and share 223 cM of DNA and so forth.

Generations relationship table

In the left column, generations begin being counted with your parents as generation 1. The cumulative number of direct line relatives you have at each generation is shown in the “# Grandparents” column.

Generations relationship levels

Here’s how to read this chart, straight across.

Viewing the “Generation” column, at the 4th generation level, you have 16 great-great-grandparents. Your great-great-grandparent is a first cousin to the the great-great-grandparent of your 4th cousin. Their parents were siblings.

Looking at it this way, it might not seem too difficult to reassemble the descendancy tree of someone 5 generations in the past, but let’s look at it from the other perspective meaning from the perspective of the ancestral couple.

Generations descendants

Couples had roughly 25 years of being reproductively capable and for most of history, birth control was non-existent. If your great-great-great-grandparents, who were born sometime near the year 1800 (the births of mine range from 1785 to 1810) had 5 children who lived, and each of their descendants had 5 children who lived, today each ancestral couple would have 3,125 descendants.

If that same couple had 10 children and 10 lived in each subsequent generation, they would have 100,000 descendants. Accuracy probably lies someplace in-between. That’s still a huge number of descendants for one couple.

That’s JUST for one couple. You have 32 great-great-great-grandparents, or 16 pairs, so multiply 16 times 3,125 for 50,000 descendants or 100,000 times 16 for…are you ready for this…1,600,000 descendants.

Descendants per GGG-grandparent couple at 5 generations Total descendants for 16 GGG-grandparent couples combined
5 children per generation 3,125 50,000
10 children per generation 100,000 1,600,000

NOW you understand why adoptees need to focus on only close matches and why distant matches at the 3rd and 4th cousin level are just too difficult to work with.

By contrast, let’s look at the first cousin row.

Generations descendants 1C.png

At 5 descendants per generation, you’ll have 25 first cousins or 100 first cousins at 10 descendants per generation.

Generations descendants 2C

At second cousins, you’ll have 125 and 1,000 – so reconstructing these trees down to current descendants is still an onerous task but much more doable than from the third or fourth cousin level, especially in smaller families.

The Perfect Scenario

Barring a fortuitous parent or sibling match, the perfect scenario for adoptees and people seeking unknown individuals means that:

  • They have multiple 1st or 2nd cousin matches making tree triangulation to a maternal and paternal group of matches to identify the common ancestors feasible.
  • Their matches have trees that allow the adoptee to construct theories of how they might fit into a family.

Following the two steps above, when sufficient matching and trees have been assembled, the verification steps begin.

  • Adoptees hope that their matches are responsive to communications requesting additional information to either confirm or refute their relationship theory. For example, my mother could tell the male adoptee that he is related on her father’s side of the family based on Family Tree DNA‘s parental “side” assignment. Based on who else the adoptee matches in common with mother, she could probably tell him how he’s related. That information would be hugely beneficial.
  • In a Doe situation where the goal is to identify remains, with a relatively close match, the investigator could contact that match and ask if they know of a missing family member.
  • In a law enforcement situation where strong close-family matches that function as hints lead to potential violent crime suspects, investigators could obtain a piece of trash discarded by the potential suspect to process and compare to the DNA from the crime scene, such as was done in the Golden State Killer case.

If the discarded DNA doesn’t match the crime scene DNA, the person is exonerated as a potential suspect. If the discarded DNA does match the crime scene DNA, investigators would continue to gather non-DNA evidence and/or pick the suspect up for questioning and to obtain a court ordered DNA sample to compare to the DNA from the crime scene in a law enforcement database.

Sometimes DNA is a Waiting Game

I know that on the surface, DNA matching for adoptees and unknown persons sounds simple, and sometimes it is if there is a very close family match.

More often than not, trying to identify unknown persons, especially if the tester doesn’t have multiple close matches is much like assembling a thousand-piece puzzle with no picture on the front of the box.

Sometimes simply waiting for a better match at some point in the future is the only feasible answer. I waited years for my brother, Dave’s family match. You can read his story here and here.

DNA is a waiting game.

MyHeritage LIVE 2019 in Amsterdam – Sign Up Now!

I’ve been waiting to share this information with you until everything was nailed down, and now I can.

I’m going to be attending and participating in MyHeritage LIVE in Amsterdam this September 6-8th. If you recall, I attended the first MyHeritage LIVE conference in Oslo last fall and loved every single minute.

If you want to take a look, I wrote about that conference, complete with photos, here and here.

MyHeritage LIVE Amsterdam 2019

This year’s conference will be held in Amsterdam, one of my favorite cities. MyHeritage wrote about it in their blog, here.

Confession

I confess, some of my ancestors were from Amsterdam. And yes, I’m incorporating the conference into an “ancestor trip” with Yvette Hoitink, Dutch genealogist extraordinaire whose blog can be found on her website here. Yvette will be presenting at the conference too, so if you’re attending, you get a chance to both hear and meet her.

I’m actually thrilled that Yvette is presenting, because I was her first customer in 2012 when she replied, then as an employee of the Dutch National Archives, to my blog article about my “hopeless” Dutch ancestors. Well, they not only weren’t hopeless, Yvette has been my genealogist ever since and we still discover documents and new ancestors on a regular basis.

Here’s that fateful exchange which was the beginning of a wonderful friendship AND of me adding more than, drum roll…2 dozen ancestors to my tree – and we’re not brick walled yet!!!

Not only that, but the newspaper articles for northern Indiana, included as part of my MyHeritage subscription, have helped me make countless discoveries in my Dutch Ferwerda (Ferverda/Fervida in the US) line after they immigrated in 1868. And I’m not referring to a couple of articles, but literally hundreds. Yes, hundreds.

With Yvette’s help, I’m connecting the Dutch DNA matches that my mother is receiving at MyHeritage. I transferred Mom’s autosomal test to MyHeritage because she’s one generation closer than I am and MyHeritage has a significant European presence. I’m so grateful that MyHeritage facilitates DNA transfers because mother passed away years before they began DNA testing. You can upload your DNA to MyHeritage for free by clicking here or order a DNA kit here.

Ok, enough excited rambling from me. You’re probably wondering who’s speaking and the presentation topics.

Who’s Speaking?

Gilad Japhet, MyHeritage founder and CEO opens the conference with the keynote. If you have never heard Gilad speak, you’re in for a wonderful treat. Gilad is a passionate genealogist and an amazing human, a trait that radiates from him as he speaks and infects the audience. No, I’m really not biased.

Last year as Gilad was discussing why he had ordered indexing of addresses in city directories in addition to names by giving an example of finding one of this ancestor’s relatives in New York City, I sat in the audience and found the building on Google maps for him, showing him afterwards. One genealogist to another. He’s that approachable.

Of course, there ARE other speakers too, many of whom I’m sure you’ll recognize!

MyHeritage LIVE Amsterdam speakers

Oh look, Yvette’s photo and mine are side by side! How perfect.

MyHeritage LIVE Amsterdam speakers 2

MyHeritage LIVE Amsterdam speakers 3

I’m very fortunate to count many of these folks as my friends and can’t wait to meet others.

And of course, I look forward to meeting and talking with you. One of the best part of conferences is who we meet.

You can take a look at the schedule, here.

The Party

I probably shouldn’t even mention this, because far be it from me to suggest that a world-class party would in any way influence your decision to attend – so let’s just say that the MyHeritage parties are both famous and infamous.

MHLive 2018 party

Me trying to take a selfie with Gilad Japhet at last year’s party.

At last year’s party, the 2018 EuroVision winners performed. This year, EuroVision was held in Israel, with MyHeritage as the sponsor and a Dutch man, Duncan Laurence won. In fact, you can watch and listen here.

Now, I don’t know what’s in store for the MyHeritage party this year, but don’t miss this event! It’s legendary.

Early Bird Pricing

Right now, the conference price is 150 Euros which is equivalent to about $170 US. You can still get discounted flights too because the conference is several weeks away.

Early bird pricing ends on July 31. Click here to sign up or read more.

OK, that’s it for now. I surely do hope to see you in Amsterdam. Let me know if you’re planning to attend!

MyHeritage Expands DNA Testing to Include (Optional) Health Information

Recently, I received news that MyHeritage is now offering a DNA test for genealogy that can also be utilized to obtain health information. I had some questions about the service and reached out to MyHeritage, so after I share their announcement, I’ll provide the information I received from MyHeritage.

The MyHeritage Health service is different from the services currently provided by either 23andMe or, individually, Promethease, by uploading your file.

MyHeritage Health and Ancestry.png

The text of the MyHeritage announcement e-mail follows below:

The new test provides comprehensive health reports that can empower future health and lifestyle choices. It is a superset of the current MyHeritage DNA test and includes its pillar features: a percentage breakdown of ethnic origins and matching to relatives through shared DNA. MyHeritage is now the only global consumer DNA company to offer an extensive health and ancestry product in dozens of languages. The two tests will be offered on our website side by side.

The new test provides health reports that show users their risk of developing or carrying genetic conditions. Reports include conditions where single genes contribute to the risk, such as hereditary breast cancer, late-onset Alzheimer’s disease, and late-onset Parkinson’s disease; conditions associated with multiple genes, such as heart disease, and type 2 diabetes; and carrier status reports on conditions that can be passed down from a couple to their children, such as Tay-Sachs disease and cystic fibrosis.

Learn more about the MyHeritage DNA Health + Ancestry test by reading the press release and the blog post.

For an overview of the new test, you are invited to view the “About MyHeritage DNA Health + Ancestry Test” video. This video has a separate version for US users.

The MyHeritage DNA Health + Ancestry kit is available at the price of $199 + shipping on the MyHeritage DNA website. Users who have already purchased the genealogical (ancestry-only) MyHeritage DNA test can upgrade to receive health reports for $120. The new health kit is available globally except in a few countries that do not allow health-related consumer genetic testing.

Privacy is our top priority. All health data is protected by state-of-the-art encryption. Health report data is secured using additional password protection and is so secure that even MyHeritage employees cannot access it. MyHeritage has never licensed or sold user data, and has committed to never do so without explicit user consent. MyHeritage is the only consumer DNA company that has pledged to never sell data to insurance companies. It also applies a strict policy to prohibit the use of its DNA services by law enforcement agencies.

There’s more detail in the MyHeritage press release:

In total, MyHeritage’s Health+Ancestry test covers one of the most extensive ranges of conditions offered by an at-home DNA test: 11 Genetic Risk Reports, including a hereditary breast cancer (BRCA) report that tests 10 pathogenic variants; 3 Polygenic Risk Reports; and 15 Carrier Status Reports.

The World Health Organization identifies cardiovascular disease as the number one cause of death globally. This makes MyHeritage’s unique report for heart disease risk particularly beneficial. This report is based on a cutting-edge method called Polygenic Risk Score that examines hundreds, and in some cases thousands of variants across the entire genome.

In addition to heart disease, the Health+Ancestry product also includes a Polygenic Risk Score for type 2 diabetes, a condition that has significantly increased in prevalence in recent decades and now affects hundreds of millions of people worldwide and 40% of Americans within their lifetime. MyHeritage is also unique in providing a third Polygenic Risk Score for breast cancer, which delivers a risk assessment for breast cancer when none of the BRCA variants that MyHeritage tests for are found. MyHeritage is currently the only major home DNA testing company to offer Polygenic Risk Reports for multiple conditions, and more Polygenic Risk Reports will be added shortly after the product’s initial release. The three initial Polygenic Risk Reports support only populations with European ancestry, but the company has begun conducting research to allow the polygenic reports to cover a broader spectrum of populations in the future.

The list of conditions and genes reported can be found here.

The unique aspect of the MyHeritage Health test is that they include diseases or conditions that are polygenic, meaning that multiple locations on multiple genes are taken into consideration in combination to create the report.

From the MyHeritage blog, for people in the US:

In the United States, we work with an independent network of physicians called PWNHealth, which supervises this new service and provides clinical oversight.

As with our current genealogical DNA kit, activation is required to associate the kit with the individual who is taking the test. With the MyHeritage DNA Health + Ancestry kit, activation must be done by the user who took the DNA test and it includes an additional step: completing a personal and family health history questionnaire. This ensures that users receive the reports that are appropriate for them. In the United States, an independent physician will review each health history questionnaire, approve the processing of the test, and evaluate all health reports before they are released. When a report indicates an increased risk for a specific condition, the physician will further determine whether genetic counseling is advised. If genetic counseling is recommended, a phone or video consultation with a genetic counselor from PWNHealth is included at no additional cost.

In the United States, the physician oversight and genetic counseling is an important benefit of the MyHeritage DNA Ancestry + Health test. This ensures that users will not be on their own when interpreting the results, in cases where the results indicate increased risk and the physician considers genetic counseling to be essential. In other words, our test provides access to experts who can help people understand their results, which our major competitor does not provide.

I personally feel that the physician oversight and access to a counselor is extremely important. I greatly appreciate that the counselor is included free in cases that merit that level of attention.

Of course, having taken the 23andMe test and utilized Promethease, I’m curious what the MyHeritage information might reveal that wasn’t covered in either of those others. In particular, my father had heart disease and my sister died of a heart attack, so I’m particularly concerned about heart health.

Questions, Answers and Things to Note

  • If you transferred your DNA to MyHeritage from any vendor, you’ll need to test on the MyHeritage chip in order to receive the health reports.
  • The health part of the test is not available to residents of NY, NH and RI due to their state laws. Sorry folks.
  • If you tested your DNA at MyHeritage, you are eligible for an upgrade to the Health product for the price of $120 by signing on to your account here and clicking on the Health tab. If you do not see the $120 upgrade option, that means that you are not eligible for the upgrade because you either haven’t tested yet, or you transferred your DNA file from another vendor.

MyHeritage Health.png

  • To order a new DNA+Health test or upgrade, click here. Current subscribers after signing on will see the new Health tab beside the DNA tab.

MyHeritage DNA tab.png

  • If you order a DNA kit without ordering through the Health tab, you’ll receive an Ancestry only test, but you can still upgrade for the $120 later, so don’t worry.

Occasionally, you can save a few $$ by ordering the initial genealogy-only MyHeritage DNA kit on sale, like for the current price of $59, then wait until your results are back and order the upgrade for $120, for a total of $179 – representing a $20 savings over the $199 price for the Ancestry+Health kit. Now is a great time to order!

  • The upgrade or purchase of the Health test provides initial health information for the first year, but after year 1, if you want updated health information as it becomes available, a health subscription costs $99 per year.

MyHeritage Health subscription.png

I was confused about exactly what the $99 Health Subscription covers, so I asked MyHeritage if I already have a full subscription (which I do, love, and you can try for free), would I still need to purchase the $99 Health Subscription?

I received the following reply:

Yes, you would still need the $99 Health Subscription, if you wish to gain access to all new Genetic Risk and Carrier Status Reports as they are released, beyond those you will get in your initial health results. None of the current subscriptions negates the need for the additional Health subscription for receiving health updates.

However, the Health Subscription will also unlock the advanced MyHeritage DNA genealogical features (see https://blog.myheritage.com/2018/12/starting-today-new-dna-upload-policy/) such as AutoClusters and Theory of Family Relativity.

So, a non-genealogist who buys the new MyHeritage DNA Health+Ancestry kit and adds the health subscription will not need to buy another type of subscription to unlock the advanced MyHeritage DNA genealogical features.

What’s Next?

MyHeritage Kit.jpg

I literally have my new MyHeritage DNA kit in my hands (because I transferred by DNA from another vendor initially) and I’m getting ready to swab.

After I receive my results, I’ll write a comparison about my MyHeritage health results as compared to my 23andMe results.

DNA Testing and Transfers – What’s Your Strategy?

The landscape of genetic genealogy is forever morphing.

I’m providing a quick update as to which vendors support file transfers from which other vendors in a handy matrix.

Come join in the fun!

Testing and Transfer Strategy

Using the following chart, you can easily plan a testing and transfer strategy.

DNA Vendor Transfer Chart 2019

Click on image to enlarge.

Caveats and footnotes as follows:

1. After May 2016, the Ancestry test is only partly compatible, meaning you receive your closest matches (about 20-25% of the total) but won’t receive distant matches due to chip incompatibility. However, beginning in April 2019, when Family Tree DNA implemented the Illumina GSA chip, Ancestry files are receiving all matches.

2. The 23andMe December 2010 (V3) version is fully compatible. December 2013-August 2017 (V4) and August 2017 (V5) tests are partly compatible meaning you receive your closest matches (about 20-25% of the total) but won’t receive distant matches due to chip incompatibility. However, beginning in April 2019, when Family Tree DNA implemented the Illumina GSA chip, 23andMe V4 and V5 files are receiving all matches.
3. GedMatch has been working to resolve autosomal matching issues between vendor’s chips. Patience is a key word.
4. LivingDNA does not yet have full blown matching (I have one match), which has been in the testing phase for months, and has recently changed chip vendors.
5. Customer must extract the file using a file utility before it can be uploaded. LivingDNA indicates that they are working on a simpler solution.
6. Files transferred to LivingDNA must be in build 37 format.
4-12-2019 update – please note that MyHeritage does not accept 23andMe V2 files, only V3, V4 and V5.

Recommendations

My recommendations are as follows, and why:

Transfer Costs

Autosomal transfers and matching are free at the vendors who accept transfers, but payment for advanced tools is required.

  • Family Tree DNA – $19 one-time unlock fee for advanced tools
  • MyHeritage – $29 one-time fee for advanced tools
  • GedMatch – many tools free, but for Tier 1 advanced tools, $10 per month

All great values!

Please note that as vendors change testing chips and file formats, other vendors who accept transfers will need time to adapt. I know it’s frustrating sometimes, but it’s a sign that technology is moving forward. The good news is that after the wait, if there is one, you’ll have a brand new group of genealogy matches – many holding clues for you to decipher.

I’m in all of the databases, so see you there.

Full or Half Siblings?

Many people are receiving unexpected sibling matches. Everyday on social media, “surprises” are being reported so often that they are no longer surprising – unless of course you’re the people directly involved and then it’s very personal, life-altering and you’re in shock. Staring at a computer screen in stunned disbelief.

Conversely, sometimes that surprise involves people we already know, love and believe to be full siblings – but autosomal DNA testing casts doubt.

If your sibling doesn’t match at all, download your DNA files and upload to another company to verify. This step can be done quickly.

Often people will retest, from scratch, with another company just for the peace of mind of confirming that a sample didn’t get swapped. If a sample was swapped, then another unknown person will match you at the sibling level, because they would be the one with your sibling’s kit. It’s extremely rare, but it has happened.

If the two siblings aren’t biologically related at all, we need to consider that one or both might have been adopted, but if the siblings do match but are predicted as half siblings, the cold fingers of panic wrap themselves around your heart because the ramifications are immediately obvious.

Your full sibling might not be your full sibling. But how can you tell? For sure? Especially when minutes seem like an eternity and your thoughts are riveted on finding the answer.

This article focuses on two tools to resolve the question of half versus full siblingship, plus a third safeguard.

Half Siblings Versus Step-Siblings

For purposes of clarification, a half sibling is a sibling you share only one parent with, while a step-sibling is your step-parent’s child from a relationship with someone other than your parent. Your step-parent marries your parent but is not your parent. You are not genetically related to your step-siblings unless your parent is related to your step-parent.

Parental Testing

Ideally two people who would like to know if they are full or half siblings would have both parents, or both “assumed” parents to compare their results with. However, life is seldom ideal and parents aren’t always available. Not to mention that parents in a situation where there was some doubt might be reluctant to test.

Furthermore, you may elect NOT to have your parents test if your test with your sibling casts doubt on the biological connections within your family. Think long and hard before exposing family secrets that may devastate people and potentially destroy existing relationships. However, this article is about the science of confirming full versus half siblings, not the ethics of what to do with that information. Let your conscience be your guide, because there is no “undo” button.

Ranges Aren’t Perfect

The good news is that autosomal DNA testing gives us the ability to tell full from half-siblings by comparing the siblings to each other, without any parent’s involvement.

Before we have this discussion, let me be very clear that we are NOT talking about using these tools to attempt to discern a relationship between two more distant unknown people. This is only for people who know, or think they know or suspect themselves to be either full or half siblings.

Why?

Because the ranges of the amount of DNA found in people sharing close family relationships varies and can overlap. In other words, different degrees of relationships can be expected to share the same amounts of DNA. Furthermore, except for parents with whom you share exactly 50% of your autosomal DNA (except males don’t share their father’s X chromosome), there is no hard and fast amount of DNA that you share with any relative. It varies and sometimes rather dramatically.

The first few lines of this Relationship Chart, from the 2016 article Concepts – Relationship Predictions, shows both first and second degree relationships (far right column).

Sibling shared cM chart 2016.png

You can see that first degree relations can be parent/child, or full siblings. Second degree relationships can be half siblings, grandparents, aunt/uncle or niece/nephew.

Today’s article is not about how to discern an unknown relation with someone, but how to determine ONLY if two people are half or full siblings to each other. In other words, we’re only trying to discern between rows two and three, above.

As more data was submitted to Blaine Bettinger’s Shared cM Project, the ranges changed as we continued to learn. Blaine’s 2017 results were combined into a useful visual tool at DNAPainter, showing various relationships.

Sibling shared cM DNAPainter.png

Note that in the 2017 version of the Shared cM Project, the high end of the half sibling range of 2312 overlaps with the low end of the full sibling range of 2209 – and that’s before we consider that the people involved might actually be statistical outliers. Outliers, by their very definition are rare, but they do occur. I have seen them, but not often. Blaine wrote about outliers here and here.

Full or Half Siblings?

So, how to we tell the difference, genetically, between full and half siblings?

There are two parts to this equation, plus an optional third safeguard:

  1. Total number of shared cM (centiMorgans)
  2. Fully Identical Regions (FIR) versus Half Identical Regions (HIR)

You can generally get a good idea just from the first part of the equation, but if there is any question, I prefer to download the results to GedMatch so I can confirm using the second part of the equation too.

The answer to this question is NOT something you want to be wrong about.

Total Number of Shared cM

Each child inherits half of each parent’s DNA, but not the same half. Therefore, full siblings will share approximately 50% of the same DNA, and half siblings will share approximately 25% when compared to each other.

You can see the differences on these charts where percentages are converted into cM (centiMorgans) and on the 2017 combined chart here.

I’ve summarized full and half siblings’ shared cMs of DNA from the 2017 chart, below.

Relationship Average Shared cM Range of Shared cM
Half Siblings 1,783 1,317 – 2,312
Full Siblings 2,629 2,209 – 3,394

Fully Identical and Half Identical Regions

Part of the DNA that full siblings inherit will be the exact same DNA from Mom and Dad, meaning that the siblings will match at the same location on their DNA on both Mom’s strand of DNA and Dad’s strand of DNA. These sections are called Fully Identical Regions, or FIR.

Half siblings won’t fully match, except for very small slivers where the nucleotides just happen to be the same (identical by chance) and that will only be for very short segments.

Half siblings will match each other, but only one parent’s side, called Half Identical Regions or HIR.

Roughly, we expect to see about 25% of the DNA of full siblings be fully identical, which means roughly half of their shared DNA is inherited identically from both parents.

Understanding the Concept of Half Identical Versus Fully Identical

To help understand this concept, every person has two strands of DNA, one from each parent. Think of two sides of a street but with the same addresses on both sides. A segment can “live” from 100-150 Main Street, er, I mean chromosome 1 – but you can’t tell just from the address if it’s on Mom’s side of the street or Dad’s.

However, when you match other people, you’ll be able to differentiate which side is which based on family members from that line and who you match in common with your sibling. This an example of why it’s so important to have close family members test.

Any one segment on either strand being compared between between full siblings can:

  • Not match at all, meaning the siblings inherited different DNA from both parents at this location
  • Match on one strand but not the other, meaning the siblings inherited the same DNA from one parent, but different DNA from the other. (Half identical.)
  • Match identically on both, meaning the siblings inherited exactly the same DNA in that location from both parents. (Fully identical.)

I created this chart to show this concept visually, reflecting the random “heads and tails” combination of DNA segments by comparing 4 sets of full siblings with one another.

Sibling full vs half 8 siblings arrows

This chart illustrates the concept of matching where siblings share:

  • No DNA on this segment (red arrow for child 1 and 2, for example)
  • Half identical regions (HIR) where siblings share the DNA from one parent OR the other (green arrow for child 1 and 2, for example, where the siblings share brown from mother)
  • Fully identical regions (FIR) where they share the same segment from BOTH parents so their DNA matches exactly on both strands (black boxed regions)

If a region isn’t either half or fully identical, it means the siblings don’t match on that piece of DNA at all. That’s to be expected in roughly 50% of the time for full siblings, and 75% of the time for half siblings. That’s no problem, unless the siblings don’t match at all, and that’s entirely different, of course.

Let’s look at how the various vendors address half versus full siblings and what tools we have to determine which is which.

Ancestry

Ancestry predicts a relationship range and provides the amount of shared DNA, but offers no tools for customers to differentiate between half versus full siblings. Ancestry has no chromosome browser to facilitate viewing DNA matches but shared matches can sometimes be useful, especially if other close family members have tested.

Sibling Ancestry.png

Update 4-4-2019 – I was contacted by a colleague who works for an Ancestry company, who provided this information: Ancestry is using “Close Family” to designate avuncular, grandparent/grandchild and half-sibling relationships. If you see “Immediate Family “the relationship is a full sibling.

Customers are not able to view the results for ourselves, but according to my colleague, Ancestry is using FIRs and HIRs behind the scenes to make this designation. The Ancestry Matching White Paper is here, dating from 2016.

If Ancestry changes their current labeling in the future, this may not longer be exactly accurate. Hopefully new labeling would provide more clarity. The good news is that you can verify for yourself at GedMatch.

A big thank you to my colleague!

MyHeritage

MyHeritage provides estimated relationships, a chromosome browser and the amount of shared DNA along with triangulation but no specific tool to determine whether another tester is a full or half sibling. One clue can be if one of the siblings has a proven second cousin or closer match that is absent for the other sibling, meaning the siblings and the second cousin (or closer) do not all match with each other.

Sibling MyHeritage.png

Family Tree DNA

At Family Tree DNA, you can see the amount of shared DNA. They also they predict a relationship range, include a chromosome browser, in common matching and family phasing, also called bucketing which sorts your matches into maternal and paternal sides. They offer additional Y DNA testing which can be extremely useful for males.

Sibling FamilyTreeDNA.png

If the two siblings in question are male, a Y DNA test will shed light on the question of whether or not they share the same father (unless the two fathers are half brothers or otherwise closely related on the direct paternal line).

Sibling advanced matches.png

FamilyTreeDNA provides Advanced Matching tools that facilitate combined matching between Y and autosomal DNA.

Sibling bucketing both.png

FamilyTreeDNA’s Family Finder maternal/paternal bucketing tool is helpful because full siblings should be assigned to “both” parents, shown in purple, not just one parent, assuming any third cousins or closer have tested on both sides, or at least on the side in question.

As you can see, on the test above, the tester matches her sister at a level that could be either a high half sibling match, or a low full sibling match. In this case, it’s a full sibling, not only because both parents tested and she matched, but because even before her parents tested, she was already bucketed to both sides based on cousins who had tested on both the maternal and paternal sides of the family.

GedMatch

GedMatch, an upload site, shows the amount of shared DNA as well. Select the One-to-One matching and the “Graph and Position” option, letting the rest of the settings default.

Sibling GedMatch menu.png

GedMatch doesn’t provide predicted relationship ranges as such, but instead estimates the number of generations to the most recent common ancestor – in this case, the parents.

Sibling GedMatch total.png

However, GedMatch does offer an important feature through their chromosome browser that shows fully identical regions.

To illustrate, first, I’m showing two kits below that are known to be full siblings.

The green areas are FIR or Fully Identical Regions which are easy to spot because of the bright green coloring. Yellow indicate half identical matching regions and red means there is no match.

Sibling GedMatch legend.png

Please note that this legend varies slightly between the legacy GedMatch and GedMatch Genesis, but yellow, green, purple and red thankfully remain the same. The blue base indicates an entire region that matches, while the grey indicates an entire region not considered a match..

Sibling GedMatch FIR.png

Fully identical green regions (FIR) above are easy to differentiate when compared with half siblings who share only half identical regions (HIR).

The second example, below, shows two half-siblings that share one parent.

Sibling GedMatch HIR.png

As you can see, there are slivers of green where the nucleotides that both parents contributed to the respective children just happen to be the same for a very short distance on each chromosome. Compared to the full sibling chart, the green looks very different.

The half-sibling small green segments are fully identical by chance or by population, but not identical by descent which would mean the segments are identical because the individuals share both parents. These two people don’t share both parents.

The fully identical regions for full siblings are much more pronounced, in addition to full siblings generally sharing more total DNA.

GedMatch is the easiest and most useful site to work with for determining half versus full siblings by comparing HIR/FIR. I wrote instructions for downloading your DNA from each of the testing vendors at the links below:

Twins

Fraternal twins are the same as regular siblings. They share the same space for 9 months but are genetically siblings. Identical twins, on the other hand, are nearly impossible to tell apart genetically, and for all intents and purposes cannot be distinguished in this type of testing.

Sibling GedMatch identical twin.png

Here’s the same chart for identical twins.

23andMe

23andMe also provides relationship estimates, along with the amount of shared DNA, a chromosome browser that includes triangulation (although they don’t call it that) and a tool to identify full versus half identical regions. 23andMe does not support trees, a critical tool for genealogists.

Unfortunately, 23andMe has become the “last” company that people use for genealogy. Most of their testers seem to be seeking health information today.

If you just happen to have already tested at 23andMe with your siblings, great, because you can use these tools. If you have not tested at 23andMe, simply upload your results from any vendor to GedMatch.

At 23andMe, under the Ancestry, then DNA Relatives tabs, click on your sibling’s match to view genetic information, assuming you both have opted into matching. If you don’t match your sibling, PLEASE be sure you BOTH have completely opted in for matching. I can’t tell you how many panic stricken siblings I’ve coached who weren’t both opted in to matching. If you’re experiencing difficulty, don’t panic. Simply download both people’s files to GedMatch for an easier comparison. You can find 23andMe download instructions here.

Sibling 23andMe HIR.png

Scrolling down, you can see the options for both half and completely identical segments on your chromosomes as compared to your match. Above,  my child matches me completely on half identical regions. This makes perfect sense, of course, because my father and my child’s father are not the same person and are not related.

Conversely, this next match is my identical twin whom I match completely identically on all segments.

Sibling 23andMe FIR.png

Confession – I don’t have an identical twin. This is actually my V3 test compared with my V4 test, but these two tests are in essence identical twin tests.

Unusual Circumstances

The combination of these two tools, DNA matching and half versus fully identical regions generally provides a relatively conclusive answer as to whether two individuals are half or full siblings. Note the words generally and relatively.

There are circumstances that aren’t as clear cut, such as when the father of the second child is a brother or other close relative of the first child’s father – assuming that both children share the same mother. These people are sometimes called three quarters siblings or niblings.

In other situations, the parents are related, sometimes closely, complicating the genetics.

These cases tend to be quite messy and should be unraveled with the help of a professional. I recommend www.dnaadoption.com (free unknown parent search specialists) or Legacy Tree Genealogists (professional genealogists.)

The Final SafeGuard – Just in Case

A third check, should any doubt remain about full versus half siblings, would be to find a relative that is a second cousin or closer on the presumed mother’s side and one on the presumed father’s side, and compare autosomal results of both relatives to both siblings.

There has never been a documented case of second cousins or closer NOT matching each other. I’m unclear about second cousins once removed, or half second cousins, but about 10% of third cousins don’t match. To date, second cousins (or closer) who didn’t match, didn’t match because they weren’t really biological second cousins.

If the two children are full siblings meaning the biological children of both the presumed parents, both siblings will match the 2nd cousin or closer on the mother’s side AND the 2nd cousin or closer on the father’s side as well. If they are not full siblings, one will match only on the second cousin on the common parent’s side.

You can see in the example below that Child 1 and Child 2, full siblings, match both Hezekiah (green), a second cousin from the father’s side, as well as Susan (pink), a second cousin from the mother’s side.

Sibling both sides matching.png

If one of the two children only matches one cousin, and not the other, then the person who doesn’t match the cousin from the father’s side, for example, is not related to the father – although depending on the distance of the relationship, I would seek an additional cousin to test through a different child – just in case.

You can see in the example below that Child 2 matches both Hezekiah (green) and Susan (pink), but Child 1 only matches Susan (pink), from the mother’s side, meaning that Child 1 does not descend from John, so isn’t the child of the Presumed Father (green).
Sibling both sides not matching.png

If neither child matches Hezekiah, that’s a different story. You need to consider the possibility of one of the following:

  • Neither child is the child of the Presumed Father, and could potentially be fathered by different men
  • A break occurred in the genetic line someplace between John and Hezekiah or between John and the Presumed Father.

In other words, the only way this safeguard works as a final check is if at least ONE of the children matches both presumed parents’ lines with a second cousin or closer.

And yes, these types of “biological lineage disruptions” do occur and much more frequently that first believed.

In the End

You may not need this safeguard check when the first and second methodologies, separately or together, are relatively conclusive. Sometimes these decisions about half versus full siblings incorporate non-genetic situational information, but be careful about tainting your scientific information with confirmation bias – meaning unintentionally skewing the information to produce the result that you might desperately want.

When I’m working with a question as emotionally loaded as trying to determine whether people are half or full siblings, I want every extra check and safeguard available – and you will too. I utilize every tool at my disposal so that I don’t inadvertently draw the wrong conclusion.

I want to make sure I’ve looked under every possible rock for evidence. I try to disprove as much as I try to prove. The question of full versus half siblingship is one of the most common topics of the Quick Consults that I offer. Even when people think they know the answer, it’s not uncommon to ask an expert to take a look to confirm. It’s a very emotional topic and sometimes we are just too close to the subject to be rational and objective.

Regardless of the genetic outcome, I hope that you’ll remember that your siblings are your siblings, your parents are your parents (genetic or otherwise) and love is love – regardless of biology. Please don’t lose the compassionate, human aspect of genealogy in the fervor of the hunt.

MyHeritage’s New Theory of Family Relativity

2019 Theory of Family Relativity

MyHeritage’s new Theory of Family Relativity, introduced February 28, 2019 at RootsTech combines the power of DNA matching with trees and documents to suggest, SUGGEST, potential common ancestors with your matches. You can read the MyHeritage announcement article here.

As the title indicates, the results are a theory about how you are related to other people you match. In fact, there may be more than one theory for a match – and multiple theories might be accurate if you descend from more than one common line.

That happened with one of my matches and the two separate theories were both accurate.

Tree resources utilized include MyHeritage trees, Geni and Family Search.

Documents include the entire library of MyHeritage resources.

I must say, I was somewhat of a Doubting Thomas on this, given the number of bad trees in cyberspace, but the results have been amazingly accurate for me.

Are Theories Accurate?

I have a total of 51 matches with theories.

There are a total of 61 theories, because some matches have multiple theories. In some cases, one is wrong and one is right. In others, both are accurate because of descent through different lines. In one case, none of the three theories were accurate because other researchers have conflated multiple William Crumley’s into one person.

However, and here’s the great news, in all cases except one, I was able to discover the correct path even in the situations where the information was not accurate. It got me “close enough” that I could do the rest myself. There is only one of 61 that I cannot yet confirm. That’s pretty amazing.

Of the 51 matches, I already knew where 20 people fit into my tree (although they weren’t in my tree at MyHeritage), so this advance knowledge helped me immensely in evaluating the accuracy of the MyHeritage genealogical theories of why these people matched me.

So are Theories accurate? Yes, for me, they are very accurate.

How Does the Theory of Family Relativity Work?

Borrowing from the MyHeritage blog article (with permission), MyHeritage shows the Big Tree with this interconnected graphic.

Theory Big Tree

They describe the Big Tree thus:

The Theory of Family Relativity™ is based on a big data graph that connects billions of data points drawn from thousands of databases on MyHeritage, in real time. We call it internally the “Big Tree”. Every node on this graph represents a person, and every edge depicts a blood relationship between two individuals that is described in a family tree or a historical record; or a match between two tree profiles that are likely to be the same person; or two records that are likely to be about the same person.

Ok, now let’s see how to use the Theories.

Finding the Theories

Sign on to your account and click on DNA.

Theory of Family Relativity

Initially, you’ll see this purple banner, but eventually you’ll just filter your matches, at right below, and look under “All tree details” and select “Theory of Family Relativity.”

Theory finding

Please note that you can click on any of the images for a larger, more clear view. Unfortunately, some images are difficult to see otherwise.

Evaluating Theories

I discovered that I have Theories for 51 matches. Many individual theories have multiple paths. In other words, MyHeritage is telling you HOW they arrived at these theories, AND they rank the paths with a confidence level based on match quality.

Please note that if you see the note “plus 1 more theory,” it’s easy to miss the second theory for a particular match. This is NOT the same thing as multiple paths on the same theory – but a completely different theory for this match altogether.

Theory multiple

To clarify, multiple paths on one theory means different trees and documents that get you and your match to the same set of common ancestors.

Different theories means that you have two potentially separate lines. Either the ancestors can be entirely different, or the path to the same ancestral couple can be different enough to result in a different end relationship for you and your match, meaning 3rd cousins versus 3rd cousins once removed for example.

I would encourage you not to skim these paths and theories, but to review them carefully and thoughtfully and compare with credible documentation.

Theory 2 theories

On a match that has multiple theories, when you view the first theory, you see “view another theory” but it’s easy to miss.

It’s worth noting that if you match on more than one segment, one segment can descend through one line and another segment through a different line. Every segment has its own history.

OK, let’s take a look. I’m going to step through my 4 closest matches with theories to illustrate how theories work and what to look for in different scenarios.

Match 1 – Known First Cousin

I filtered for matches with theories and here’s my first match.

Theory match 1

I happen to know the identity of this match who just happens to be my first cousin who is not in my tree. (I know, my bad.) However, knowing exactly how they matched and not having them in my tree helped me evaluate the accuracy of Theories.

To view the theory, click on “View theory.”

Match 1 – Path 1

You’ll notice immediately that this match has three different paths. Path 1, the highest confidence path, is displayed first.

Theory match 1 path 1

Path 1 of this theory, with a 74 % confidence level is that the tester is my first cousin on my mother’s side, based on first, DNA, and secondarily trees that show we have a common grandfather, John Ferverda.

This happens to be correct.

To review the match that connects the trees (John Ferverda), click on the green icon on the seam between the two trees. You’ll see the display below, which shows at the top that the 74% confidence factor is predicated on a SmartMatch showing a common ancestor in a tree.

I’ve noticed that it appears that the only SmartMatches that receive Theories are those with incomplete couples or with matches that aren’t clear enough to be deemed a definitive match. Don’t assume that people with SmartMatches don’t have Theories or that people with Theories don’t have SmartMatches. Filter for both separately.

On this match with both a Theory and SmartMatch, the Profile card information is not an exact match – which is probably why the confidence level is only 74%.

theory Ferverda profile

The red arrows above have to be the matching criteria because the information is either the same or similar. However, they aren’t exact. My tree is much more robust than my cousin’s tree.

The red squares are differences between the trees. Note that in one case, a surname is misspelled in my tree and my cousin’s tree is missing a great deal of information, including our grandmother’s surname.

Match 1 – Path 2

Path 2 shows that my record in my tree matches a record of me in my cousin’s tree.

Theory match 1 path 2.png

Note that in Path 2, my cousin doesn’t show either his parent or my mother as deceased. However, I’m living and showing in both trees. MyHeritage would not expose a living person unless both people gave permission by participating in matching, which is probably why neither of our parents are matched, even though both are deceased.

Clicking on the 93% green joining spinner, we can see that my cousin did not enter my father’s name and he doesn’t show my mother as deceased, which is why she is showing in his tree as private.

Theory match 1 path 2 profile.png

Match 1 – Path 3

Path 3 is actually quite interesting because it’s made up of two separate items, one being a tree match and one being a record match from the 1940 census.

Theory match 1 path 3.png

In this example, you can see three different records and the two “join seams.”

Beginning at the left, my tree is joined at my mother to the census record by the 1940 census. Note that my mother’s name is misspelled in the census. The 1940 census record is joined to my cousin’s tree by my mother’s father.

Theory match 1 path 3 review.png

This record just happens to be accurate, but the information is not identical, but similar – hence the low confidence score.

The second link between the census and my grandfather is shown below.

Theory 1 match 3 profile.png

This match connects John Ferverda, but there’s a lot missing in my cousin’s tree and my mother’s middle name is misspelled.

Match 1 Conclusion

All 3 paths are accurate, just different, which can provide me with various hints as to trees and records to view for additional information.

Match 1 Suggestions

These suggestions are in no way criticisms – it’s just that genealogists are always wanting something more😊

I’d love to be able to do three things at this point.

  • First, to click through to view the specific census page. You can hover over the record description and search the collection, but I’d like to automatically see this record since MyHeritage already found it for me.

Theory census.png

  • Second, to be notified if I already have the census attached to any of these people in my tree and if not, to have the option of attaching the census record directly from this point.
  • Third, add my cousin to my tree in the proper location. Not automatically, but with prompts perhaps.

Match 2 – Known Half Niece

This second match is my half-sister’s daughter. Half relationships are more difficult to discern.

There are two ways to reach theories.

  • Through your match page by filtering for “Theories.”
  • Through your “Review DNA Match” page.

A short summary of the most confident theory, shown below, is provided on the “Review DNA Match” page, with a link to view the full theory.

Theory match 2.png

On this summary page, the relationship between my sister and me is correctly shown as half, but the relationship with my half-niece is simply shown as niece. While I’ve always referred to my sister as my sister and my niece as my niece, and this may seem picky, it’s not genetically, because it means that we likely share about half as much DNA as a full sibling or a full niece would share. You can see the differences in the chart in the article here. Full siblings share approximately 50% of their DNA and half share approximately 25%. A full niece would share about 25% and a half niece about 12.5%.

Click on the purple “View Full Theory” button to reach the Review DNA Match page from the summary page, or, you can return to the DNA Match page, shown below.

Theory match 2 theory.png

By clicking on “View theory,” I see the following:

Theory match 2 half niece.png

The theory is actually accurate, but the relationship is named incorrectly on the Theory of Family Relativity page. My sister is actually my half-sister and this person that I match is actually my half-niece since my father had me and my sister by different wives.

Theory review match icon.png

On the Theory of Family Relativity main page, by clicking on the little green join icon above the percentage sign, I can review the match as shown below.

Theory review match profile.png

There is a lot of common information (red arrows), but there is also a lot of different or missing information (red boxes). For example, my father’s death date is incorrect in my match’s tree. The city is the same, but the county is missing in one record. Siblings are shown in my record, but not hers. My name is correct, then incorrect in the other record, including being listed with my mother’s maiden name and also with my former husband’s surname.

Theory view tree.png

Note that by flying over any MyHeritage link you can click to see the tree, which means you can click to view the profile of any individual in the tree. I’m showing mine to illustrate, but it works the same for any site listed.

When viewing the tree, click on the “box” of the person you want to view to display their detailed information at left, below.

Theory tree and profile.png

To view the attached records, click on Profile.

Theory profile records.png

You’ll notice that there are two records attached to my father, but no census, SSDI or otherwise. Don’t neglect the second, “Events” tab.

The “Events” tab, shown below, shows that indeed, he was shown in the 1910 census. If you click on the citations for any event, you’ll see the source for that piece of information. In this case, the 1910 census, even though I haven’t attached the actual image to his profile. I should do that!

Theory profile events.png

Match 2 Conclusion

This match theory is accurate.

Match 2 Suggestions

  • I’ll notify MyHeritage that their half relationships are mislabeled an I’m sure they will correct that.
  • I would like to be able to message the other person from these screens to ask them a question or inform them politely of an issue, such as my father’s death date. I would also like to be able to “invite” them to attach a record, such as a death certificate or census, for example, if it’s attached to my account.

Match 3 – Known Third Cousin Once Removed

This person descends through my great-grandparents and is my 3rd cousin once removed.

Theory match 3.png

By clicking on “View theory,” I see her tree and mine.

Theory match 3 theory.png

This stitched three tree theory is incorrect.

The middle tree shows that Margaret Clarkson was married to William Lake Monday.  She wasn’t, but her daughter Surrelda, was married to William Luke? Monday. The middle person’s tree has incorrectly married my great-grandmother to her daughter’s husband. This is the perfect example of GIGO (garbage in, garbage out) BUT, and a very big BUT, MyHeritage very clearly says these are theories and need to be verified and proven.

The second path is exactly the same as the first path, except that a different person has the exact same inaccurate information in their tree.

Match 3 Conclusion

The match 3 theory is inaccurate due to an inaccurate tree. However, if I didn’t already have this information, I have a new hint to work with.

Match 4 – Previously Unknown Third Cousin

This fourth match is more interesting for me, because I don’t know Shela or why I match her DNA.

Theory match 4 unknown.png

Shela is estimated, by DNA alone, to be my 3rd to 5th cousin.

Notice I don’t have a “Smart Match” with Shela which means that she and I don’t have a common ancestor in our trees, so how we match isn’t evident and wouldn’t be without a significant amount of work.

By clicking on “View theory” I can see how MyHeritage thinks we are related.

Match 4- Path 1

Theory match 4 path 1.png

This is actually very cool, because I just verified this connection through Leora. Obviously, Shela knows who her mother is, confirmed by DNA matches.

The path to confirmation is me ‘up” through Rachel Hill, who connects through the Family Search data base, then “down” to Shela’s mother, Leora. The amazing thing is that Shela has provided just one generation, her mother, that could match on her mother’s side of the tree. She has entered her grandmother by her married name, so Family Search picked up on the daughter, Leora Snyder. I’ve reached out to Shela, and if she’s interested, I can take her back generations on her maternal grandmother’s line.

Theory match 4 surname difference.png

Match 4 – Path 2

The second path reaches the same conclusion but connects through my grandmother which is an exact match at FamilySearch. That could be because I originally entered the FamilySearch information.

Theory match 4 path 2.png

It’s interesting that the link between the two Edith Barbara Lores is 100%, while the link between Leora V Snyder and Leora Snyder remains at 57%. MyHeritage uses the smaller of the various confidence scores to rank the entire path.

Match 4 – Path 3

This last pathway also reaches the same conclusion but connects three times with three seams: my tree to another MyHeritage tree, to FamilySearch, to Shela’s tree once again.

Theory match 4 path 3.png

Match 4 Conclusion

Match 4 is accurate whether you utilize path 1, 2 or 3.

Match 4 Suggestion

  • I would like to be able to confirm or dismiss these theories, once I’ve worked them, and have them categorized as such and held separately from new Theories that I need to work with.
  • I would like the ability to flag a theory as “seen” even if I don’t confirm or dismiss the theory so that I know it’s still a possibility.
  • I would like to quickly see if I match the owner of the intermediate trees. You can view the tree owner information when you fly over the name of the person who manages the tree.

Theory DNA icon suggestion.png

I created an example with a DNA icon. If I also match the person whose tree is being used as an intermediate, Mr. Jones in this case, I want to see that little helix icon and be able to click on it and see my match with Mr. Jones.

  • I would love to be notified by e-mail of new theories as they emerge.
  • I would like to see on the Shared DNA Matches section of the Review DNA Match page whether each match has either a shared ancestor or a theory, along with the names, so that I don’t have to go back and look individually.

Theory theory or smartmatch suggestion.png

  • I would like my “Notes” icon to show on the Shared DNA Matches view so that I can see if I’ve identified the relationship to this person. I use notes extensively.

Next Steps

Since the first three matches were already known to me and I used them as proof of concept, I don’t have homework from those, but I do from my newly discovered third cousin, Shela. What’s next and how can I further utilize this information?

  1. I’ve already clicked on the “contact Shela” on the match page. You can also fly over the name of the person managing the website at the top of the Theory page to contact as well

I told Shela that I was pleased to find this match through Theories of Relativity and that if she’s interested, I can provide her with additional information on her maternal grandmother’s line. Won’t she be surprised! I bet she doesn’t know she has a river pirate in her lineage! Maybe I won’t go there right away😊

Theory contact.png

  1. I’m going to see if Shela triangulates with other matches from this line by reviewing the DNA match.

theory review dna match.png

I noticed immediately that Shela triangulates with other known relatives on this line, such as match #1.

  1. Shela and I share 3 DNA segments, which I’m going to immediately paint on DNAPainter. You can read about DNAPainter here and here.

Theory paint chromosomes.png

  1. Shela also carries the mitochondrial DNA of Rachel Levina Hill because she descends through all females to the current generation (which can be male.) You can read more about mitochondrial DNA here. If Shela replies to me, I’ll offer to test her mitochondrial DNA at FamilyTreeDNA (MyHeritage doesn’t do mitochondrial testing) so we both have that information about our common ancestor, Rachel.

I’m only to Theory 4 of 51 matches, and it’s already a great day!

How to Get Theories of Relativity

If you tested at MyHeritage or transferred your DNA to MyHeritage prior to December 16, 2018, Theories of Family Relativity is free and included. If you transferred after that date, there’s a one time $29 fee (per kit) or you can subscribe to MyHeritage to avoid the unlock fee.

Truthfully, I recommend the subscription over the unlock fee, in part, because the subscription covers all kits uploaded to your account and you can try a subscription for free by clicking here. I already subscribe to Ancestry and doubted for a long time the utility of a second records subscription, but I’ve found the MyHeritage subscription absolutely indispensable this past year with many records (96 billion total) and collections at MyHeritage not found elsewhere. For example, I found over 1000 invaluable newspaper articles alone on the Ferverda family, farmers in northern Indiana.

If you haven’t tested at MyHeritage, you can transfer your kits from other vendors. I wrote the article, “MyHeritage Step by Step Guide: How to Upload-Download DNA Files.”

If you tested elsewhere, you can transfer today and pay the one time $29 unlock fee or subscribe to unlock Theories of Family Relativity and other advanced features.

You have not tested elsewhere, meaning you can’t transfer, you can order a DNA testing kit at this link.

This does NOT increase the price you pay but helps me to keep the lights on and this informational blog free for everyone. Please click on the links in the articles or to the vendors below if you are purchasing products or DNA testing.

Thank you so much.
