2019: The Year and Decade of Change

2019 ends both a year and a decade. In the genealogy and genetic genealogy world, the overwhelmingly appropriate word to define both is “change.”

Everything has changed.

Millions more records are online now than ever before, both through the Big 3, being FamilySearch, MyHeritage and Ancestry, but also through multitudes of other sites preserving our history. Everyplace from National Archives to individual blogs celebrating history and ancestors.

All you need to do is google to find more than ever before.

I don’t know about you, but I’ve made more progress in the past decade that in all of the previous ones combined.

Just Beginning?

If you’re just beginning with genetic genealogy, welcome! I wrote this article just for you to see what to expect when your DNA results are returned.

If you’ve been working with genetic genealogy results for some time, or would like a great review of the landscape, let’s take this opportunity to take a look at how far we’ve come in the past year and decade.

It’s been quite a ride!

What Has Changed?

EVERYTHING

Literally.

A decade ago, we had Y and mitochondrial DNA, but just the beginning of the autosomal revolution in the genetic genealogy space.

In 2010, Family Tree DNA had been in business for a decade and offered both Y and mitochondrial DNA testing.

Ancestry offered a similar Y and mtDNA product, but not entirely the same markers, nor full sequence mitochondrial. Ancestry subsequently discontinued that testing and destroyed the matching database. Ancestry bought the Sorenson database that included Y, mitochondrial and autosomal, then destroyed that data base too.

23andMe was founded in 2006 and began autosomal testing in 2007 for health and genealogy. Genealogists piled on that bandwagon.

Family Tree DNA added autosomal to their menu in 2010, but Ancestry didn’t offer an autosomal product until 2012 and MyHeritage not until 2016. Both Ancestry and MyHeritage have launched massive marketing and ad campaigns to help people figure out “who they are,” and who their ancestors were too.

Family Tree DNA

2019 FTDNA

Family Tree DNA had a banner year with the Big Y-700 product, adding over 211,000 Y DNA SNPs in 2019 alone to total more than 438,000 by year end, many of which became newly defined haplogroups. You can read more here. Additionally, Family Tree DNA introduced the Block Tree and public Y and public mitochondrial DNA trees.

Anyone who ignores Y DNA testing does so at their own peril. Information produced by Y DNA testing (and for that matter, mitochondrial too) cannot be obtained any other way. I wrote about utilizing mitochondrial DNA here and a series about how to utilize Y DNA begins in a few days.

Family Tree DNA remains the premier commercial testing company to offer high resolution and full sequence testing and matching, which of course is the key to finding genealogy solutions.

In the autosomal space, Family Tree DNA is the only testing company to provide Phased Family Matching which uses your matches on both sides of your tree, assuming you link 3rd cousins or closer, to assign other testers to specific parental sides of your tree.

Family Tree DNA accepts free uploads from other testing companies with the unlock for advanced features only $19. You can read about that here and here.

MyHeritage

MyHeritage, the DNA testing dark horse, has come from behind from their late entry into the field in 2016 with focused Europeans ads and the purchase of Promethease in 2019. Their database stands at 3.7 million, not as many as either Ancestry or 23andMe, but for many people, including me – MyHeritage is much more useful, especially for my European lines. Not only is MyHeritage a genealogy company, piloted by Gilad Japhet, a passionate genealogist, but they have introduced easy-to-use advanced tools for consumers during 2019 to take the functionality lead in autosomal DNA.

2019 MyHeritage.png

You can read more about MyHeritage and their 2019 accomplishments, here.

As far as I’m concerned, the MyHeritage bases-loaded 4-product “Home Run” makes MyHeritage the best solution for genetic genealogy via either testing or transfer:

  • Triangulation – shows testers where 3 or more people match each other. You can read more, here.
  • Tree Matching – SmartMatching for both DNA testers and those who have not DNA tested
  • Theories of Family Relativity – a wonderful new tool introduced in February. You can read more here.
  • AutoClusters – Integrated cluster technology helps you to visualize which groups of people match each other.

One of their best features, Theories of Family Relativity connects the dots between people you DNA match with disparate trees and other documents, such as census. This helps you and others break down long-standing brick walls. You can read more, here.

MyHeritage encourages uploads from other testing companies with basic functions such as matching for free. Advanced features cost either a one-time unlock fee of $29 or are included with a full subscription which you can try for free, here. You can read about what is free and what isn’t, here.

You can develop a testing and upload strategy along with finding instructions for how to upload here and here.

23andMe

Today, 23andMe is best known for health, having recovered after having had their wings clipped a few years back by the FDA. They were the first to offer Health results, leveraging the genealogy marketspace to attract testers, but have recently been eclipsed by both Family Tree DNA with their high end full Exome Tovana test and MyHeritage with their Health upgrade which provides more information than 23andMe along with free genetic counseling if appropriate. Both the Family Tree DNA and MyHeritage tests are medically supervised, so can deliver more results.

23andMe has never fully embraced genetic genealogy by adding the ability to upload and compare trees. In 2019, they introduced a beta function to attempt to create a genetic tree on your behalf based on how your matches match you and each other.

2019 23andMe.png

These trees aren’t accurate today, nor are they deep, but they are a beginning – especially considering that they are not based on existing trees. You can read more here.

The best 23andMe feature for genealogy, as far as I’m concerned, is their ethnicity along with the fact that they actually provide testers with the locations of their ethnicity segments which can help testers immensely, especially with minority ancestry matching. You can read about how to do this for yourself, here.

23andMe generally does not allow uploads, probably because they need people to test on their custom-designed medical chip. Very rarely, once that I know of in 2018, they do allow uploads – but in the past, uploaders do not receive all of the genealogy features and benefits of testing.

You can however, download your DNA file from 23andMe and upload elsewhere, with instructions here.

Ancestry

Ancestry is widely known for their ethnicity ads which are extremely effective in recruiting new testers. That’s the great news. The results are frustrating to seasoned genealogists who get to deal with the fallout of confused people trying to figure out why their results don’t match their expectations and family stories. That’s the not-so-great news.

However, with more than 15 million testers, many of whom DO have genealogy trees, a serious genealogist can’t *NOT* test at Ancestry. Testers do need to be aware that not all features are available to DNA testers who don’t also subscribe to Ancestry’s genealogy subscriptions. For example, you can’t see your matches’ trees beyond a 5 generation preview without a subscription. You can read more about what you do and don’t receive, here.

Ancestry is the only one of the major companies that doesn’t provide a chromosome browser, despite pleas for years to do so, but they do provide ThruLines that show you other testers who match your DNA and show a common ancestor with you in their trees.

2019 Ancestry.png

ThruLines will also link partial trees – showing you ancestral descendants from the perspective of the ancestor in question, shown above. You can read about ThruLines, here.

Of course, without a chromosome browser, this match is only as good as the associated trees, and there is no way to prove the genealogical connection. It’s possible to all be wrong together, or to be related to some people through a completely different ancestor. Third party tools like Genetic Affairs and cluster technology help resolve these types of issues. You can read more, here.

You can’t upload DNA files from other testing companies to Ancestry, probably due to their custom medical chip. You can download your file from Ancestry and upload to other locations, with instructions here.

Selling Customers’ DNA

Neither Family Tree DNA, MyHeritage nor Gedmatch sell, lease or otherwise share their customers’ DNA, and all three state (minimally) they will not in the future without prior authorization.

All companies utilize their customers’ DNA internally to enhance and improve their products. That’s perfectly normal.

Both Ancestry and 23andMe sell consumers DNA to both known and unknown partners if customers opt-in to additional research. That’s the purpose of all those questions.

If you do agree or opt-in, and for those who tested prior to when the opt-in began, consumers don’t know who their DNA has been sold to, where it is or for what purposes it’s being utilized. Although anonymized (pseudonymized) before sale, autosomal results can easily be identified to the originating tester (if someone were inclined to do so) as demonstrated by adoptees identifying parents and law enforcement identifying both long deceased remains and criminal perpetrators of violent crimes. You can read more about re-identification here, although keep in mind that the re-identification frequency (%) would be much higher now than it was in 2018.

People are widely split on this issue. Whatever you decide, to opt-in or not, just be sure to do your homework first.

Always read the terms and conditions fully and carefully of anything having to do with genetics.

Genealogy

The bottom line to genetic genealogy is the genealogy aspect. Genealogists want to confirm ancestors and discover more about those ancestors. Some information can only be discovered via DNA testing today, distant Native heritage, for example, breaking through brick walls.

This technology, as it has advanced and more people have tested, has been a godsend for genealogists. The same techniques have allowed other people to locate unknown parents, grandparents and close relatives.

Adoptees

Not only are genealogists identifying people long in the past that are their ancestors, but adoptees and those seeking unknown parents are making discoveries much closer to home. MyHeritage has twice provided thousands of free DNA tests via their DNAQuest program to adoptees seeking their biological family with some amazing results.

The difference between genealogy, which looks back in time several generations, and parent or grand-parent searches is that unknown-parent searches use matches to come forward in time to identify parents, not backwards in time to identify distant ancestors in common.

Adoptee matching is about identifying descendants in common. According to Erlich et al in an October 2018 paper, here, about 60% of people with European ancestry could be identified. With the database growth since that time, that percentage has risen, I’m sure.

You can read more about the adoption search technique and how it is used, here.

Adoptee searches have spawned their own subculture of sorts, with researchers and search angels that specialize in making these connections. Do be aware that while many reunions are joyful, not all discoveries are positively received and the revelations can be traumatic for all parties involved.

There’s ying and yang involved, of course, and the exact same techniques used for identifying biological parents are also used to identify cold-case deceased victims of crime as well as violent criminals, meaning rapists and murderers.

Crimes Solved

The use of genetic genealogy and adoptee search techniques for identifying skeletal remains of crime victims, as well as identifying criminals in order that they can be arrested and removed from the population has resulted in a huge chasm and division in the genetic genealogy community.

These same issues have become popular topics in the press, often authored by people who have no experience in this field, don’t understand how these techniques are applied or function and/or are more interested in a sensational story than in the truth. The word click-bait springs to mind although certainly doesn’t apply equally to all.

Some testers are adamantly pro-usage of their DNA in order to identify victims and apprehend violent criminals. Other testers, not so much and some, on the other end of the spectrum are vehemently opposed. This is a highly personal topic with extremely strong emotions on both sides.

The first such case was the Golden State Killer, which has been followed in the past 18 months or so by another 100+ solved cases.

Regardless of whether or not people want their own DNA to be utilized to identify these criminals and victims, providing closure for families, I suspect the one thing we can all agree on is that we are grateful that these violent criminals no longer live among us and are no longer preying on innocent victims.

I wrote about the Golden State Killer, here, as well as other articles here, here, here and here.

In the genealogy community, various vendors have adopted quite different strategies relating to these kinds of searches, as follows:

  • Ancestry, 23andMe and MyHeritage – have committed to fight all access attempts by law enforcement, including court ordered subpoenas.
  • MyHeritage, Family Tree DNA and GedMatch allow uploads, so forensic kits, meaning kits from deceased remains or rape kits could be uploaded to search for matches, the same as any other kit. Law Enforcement uploads violate the MyHeritage terms of service. Both Family Tree DNA and GEDmatch have special law enforcement procedures in place. All three companies have measures in place to attempt to detect unauthorized forensic uploads.
  • Family Tree DNA has provided a specific Law Enforcement protocol and guidelines for forensic uploads, here. All EU customers were opted out earlier in 2019, but all new or existing non-EU customers need to opt out if they do not want their DNA results available for matching to law enforcement kits.
  • GEDmatch was recently sold to Verogen, a DNA forensics company, with information, here. Currently GEDMatch customers are opted-out of matching for law enforcement kits, but can opt-in. Verogen, upon purchase of GEDmatch, required all users to read the terms and conditions and either accept the terms or delete their kits. Users can also delete their kits or turn off/on law enforcement matching at any time.

New Concerns

Concerns in late 2019 have focused on the potential misuse of genetic matching to potentially target subsets of individuals by despotic regimes such as has been done by China to the Uighurs.

You can read about potential risks here, here and here, along with a recent DoD memo here.

Some issues spelled out in the papers can be resolved by vendors agreeing to cryptographically sign their files when customers download. Of course, this would require that everyone, meaning all vendors, play nice in the sandbox. So far, that hasn’t happened although I would expect that the vendors accepting uploads would welcome cryptographic signatures. That pretty much leaves Ancestry and 23andMe. I hope they will step up to the plate for the good of the industry as a whole.

Relative to the concerns voiced in the papers and by the DoD, I do not wish to understate any risks. There ARE certainly risks of family members being identified via DNA testing, which is, after all, the initial purpose even though the current (and future) uses were not foreseen initially.

In most cases, the cow has already left that barn. Even if someone new chooses not to test, the critical threshold is now past to prevent identification of individuals, at least within the US and/or European diaspora communities.

I do have concerns:

  • Websites where the owners are not known in the genealogical community could be collecting uploads for clandestine purposes. “Free” sites are extremely attractive to novices who tend to forget that if you’re not paying for the product, you ARE the product. Please be very cognizant and leery. Actually, just say no unless you’re positive.
  • Fearmongering and click-bait articles in general will prevent and are already causing knee-jerk reactions, causing potential testers to reject DNA testing outright, without doing any research or reading terms and conditions.
  • That Ancestry and 23andMe, the two major vendors who don’t accept uploads will refuse to add crypto-signatures to protect their customers who download files.

Every person needs to carefully make their own decisions about DNA testing and participating in sharing through third party sites.

Health

Not surprisingly, the DNA testing market space has cooled a bit this past year. This slowdown is likely due to a number of factors such as negative press and the fact that perhaps the genealogical market is becoming somewhat saturated. Although, I suspect that when vendors announce major new tools, their DNA kit sales spike accordingly.

Look at it this way, do you know any serious genealogists who haven’t DNA tested? Most are in all of the major databases, meaning Ancestry, 23andMe, FamilyTreeDNA, MyHeritage and GedMatch.

All of the testing companies mentioned above (except GEDmatch who is not a testing company) now have a Health offering, designed to offer existing and new customers additional value for their DNA testing dollar.

23andMe separated their genealogy and health offering years ago. Ancestry and MyHeritage now offer a Health upgrade. For existing customers, FamilyTreeDNA offers the Cadillac of health tests through Tovana.

I would guess it goes without saying here that if you really don’t want to know about potential health issues, don’t purchase these tests. The flip side is, of course, that most of the time, a genetic predisposition is nothing more and not a death sentence.

From my own perspective, I found the health tests to be informative, actionable and in some cases, they have been lifesaving for friends.

Whoever knew genealogy might save your life.

Innovative Third-Party Tools

Tools, and fads, come and go.

In the genetic genealogy space, over the years, tools have burst on the scene to disappear a few months later. However, the last few years have been won by third party tools developed by well-known and respected community members who have created tools to assist other genealogists.

As we close this decade, these are my picks of the tools that I use almost daily, have proven to be the most useful genealogically and that I feel I just “couldn’t live without.”

And yes, before you ask, some of these have a bit of a learning curve, but if you are serious about genealogy, these are all well worthwhile:

  • GedMatch – offers a wife variety of tools including triangulation, half versus fully identical segments and the ability to see who your matches also match. One of the tools I utilize regularly is segment search to see who else matches me on a specific segment, attached to an ancestor I’m researching. GedMatch, started by genealogists, has lasted more than a decade prior to the sale in December 2019.
  • Genetic Affairs – a barn-burning newcomer developed by Evert-Jan Blom in 2018 wins this years’ “Best” award from me. Genetic Affairs offers clustering, tree building between your matches even when YOU don’t have a tree. You can read more here.

2019 genetic affairs.png

Just today, Genetic Affairs released a new cluster interface with DNAPainter, example shown above.

  • DNAPainter – THE chromosome painter created by Jonny Perl just gets better and better, having added pedigree tree construction this year and other abilities. I wrote a composite instructional article, here.
  • DNAGedcom.com and Genetic.Families, affiliated with DNAAdoption.org – Rob Warthen in collaboration with others provides tools like clustering combined with triangulation. My favorite feature is the gathering of all direct ancestors of my matches’ trees at the various vendors where I’ve DNA tested which allows me to search for common surnames and locations, providing invaluable hints not otherwise available.

Promising Newcomer

  • MitoYDNA – a non-profit newcomer by folks affiliated with DNAAdoption and DNAGedcom is designed to replace YSearch and MitoSearch, both felled by the GDPR ax in 2018. This website allows people to upload their Y and mitochondrial DNA results and compare the values to each other, not just for matching, which you can do at Family Tree DNA, but also to see the values that do and don’t match and how they differ. I’ll be taking MitoYDNA for a test drive after the first of the year and will share the results with you.

The Future

What does the future hold? I almost hesitate to guess.

  • Artificial Intelligence Pedigree Chart – I think that in the not-too-distant future we’ll see the ability to provide testers with a “one and done” pedigree chart. In other words, you will test and receive at least some portion of your genealogy all tidily presented, red ribbon untied and scroll rolled out in front of you like you’re the guest on one of those genealogy TV shows.

Except it’s not a show and is a result of DNA testing, segment triangulation, trees and other tools which narrow your ancestors to only a few select possibilities.

Notice I said, “the ability to.” Just because we have the ability doesn’t mean a vendor will implement this functionality. In fact, just think about the massive businesses built upon the fact that we, as genealogists, have to SEARCH incessantly for these elusive answers. Would it be in the best interest of these companies to just GIVE you those answers when you test?

If not, then these types of answers will rest with third parties. However, there’s a hitch. Vendors generally don’t welcome third parties offering advanced tools and therefore block those tools, even though they are being used BY the customer or with their explicit authorization to massage their own data.

On the other hand, as a genealogist, I would welcome this feature with open arms – because as far as I’m concerned, the identification of that ancestor is just the first step. I get to know them by fleshing out their bones by utilizing those research records.

In fact, I’m willing to pony up to the table and I promise, oh-so-faithfully, to maintain my subscription lifelong if one of those vendors will just test me. Please, please, oh pretty-please put me to the test!

I guess you know what my New Year’s Wish is for this and upcoming years now too😊

What About You?

What do you think the high points of 2019 have been?

How about the decade?

What do you think the future holds?

Do you care to make any predictions?

Are you planning to focus on any particular goal or genealogy problem in 2020?

Triangulation in Action at MyHeritage

Recently, I published the article, Hitting a Genealogy Home Run Using Your Double-Sided Two-Faced Chromosomes While Avoiding Imposters. The “Home Run” article explains why you want to use a chromosome browser, what you’re seeing and what it means to you.

This article, and the rest in the “Triangulation in Action” series introduces triangulation at FamilyTreeDNA, MyHeritage, 23andMe, GedMatch and DNAPainter, explaining how to use triangulation to confirm descent from a common ancestor. You may want to read the introductory article first.

This first section, “What is Triangulation” is a generic tutorial. If you don’t need the tutorial, skip to the “Triangulation at MyHeritage” section.

What is Triangulation?

Think of triangulation as a three-legged stool – a triangle. Triangulation requires three things:

  1. At least three (not closely related) people must match
  2. On the same reasonably sized segment of DNA and
  3. Descend from a common ancestor

Triangulation is the foundation of confirming descent from a common ancestor, and thereby assigning a specific segment to that ancestor. Without triangulation, you might just have a match to someone else by chance. You can confirm mathematical triangulation, numbers 1 and 2, above, without knowing the identity of the common ancestor.

Reasonably sized segments are generally considered to be 7cM or above on chromosomes 1-22 and 15cM or above for the X chromosome.

Boundaries

Triangulation means that all three, or more, people much match on a common segment. However, what you’re likely to see is that some people don’t match on the entire segment, meaning more or less than others as demonstrated in the following examples.

FTDNA Triangulation boundaries

You can see that I match 5 different cousins who I know descend from my father’s side on chromosome 15 above. “I” am the grey background against which everyone else is being compared.

I triangulate with these matches in different ways, forming multiple triangulation groups that I’ve discussed individually, below.

Triangulation Group 1

FTDNA triangulation 1

Group 1 – On the left group of matches, above, I triangulate with the blue, red and orange person on the amount of DNA that is common between all of them, shown in the black box. This is triangulation group 1.

Triangulation Group 2

FTDNA triangulation 2

Group 2 – However, if you look just at the blue and orange triangulated matches bracketed in green, I triangulate on slightly more. This group excludes the red person because their beginning point is not the same, or even close. This is triangulation group 2.

Triangulation Group 3 and 4

FTDNA triang 3

Group 3 – In the right group of matches, there are two large triangulation groups. Triangulation group 3 includes the common portions of blue, red, teal and orange matches.

Group 4 – Triangulation group 4 is the skinny group at right and includes the common portion of the blue, teal and dark blue matches.

Triangulation Groups 5 and 6

FTDNA triang 5

Group 5 – There are also two more triangulation groups. The larger green bracketed group includes only the blue and teal people because their end locations are to the right of the end locations of the red and orange matches. This is triangulation group 5.

Group 6 – The smaller green bracketed group includes only the blue and teal person because their start locations are before the dark blue person. This is triangulation group 6.

There’s actually one more triangulation group. Can you see it?

Triangulation Group 7

FTDNA triang 7

Group 7 – The tan group includes the red, teal and orange matches but only the areas where they all overlap. This excludes the top blue match because their start location is different. Triangulation group 7 only extends to the end of the red and orange matches, because those are the same locations, while the teal match extends further to the right. That extension is excluded, of course.

Slight Variations

Matches with only slight start and end differences are probably descended from the same ancestor, but we can’t say that for sure (at this point) so we only include actual mathematically matching segments in a triangulation group.

You can see that triangulation groups often overlap because group members share more or less DNA with each other. Normally we don’t bother to number the groups – we just look at the alignment. I numbered them for illustration purposes.

Shared or In-Common-With Matching

Triangulation is not the same thing as a 3-way shared “in-common-with” match. You may share DNA with those two people, but on entirely different segments from entirely different ancestors. If those other two people match each other, it can be on a segment where you don’t match either of them, and thanks to an ancestor that they share who isn’t in your line at all. Shared matches are a great hint, especially in addition to other information, but shared matches don’t necessarily mean triangulation although it’s a great place to start looking.

I have shared matches where I match one person on my maternal side, one on my paternal side, and they match each other through a completely different ancestor on an entirely different segment. However, we don’t triangulate because we don’t all match each other on the SAME segment of DNA. Yes, it can be confusing.

Just remember, each of your segments, and matches, has its own individual history.

Imputation Can Affect Matching

Over the years the chips on which our DNA is processed at the vendors have changed. Each new generation of chips tests a different number of markers, and sometimes different markers – with the overlaps between the entire suite of chips being less than optimal.

I can verify that most vendors use imputation to level the playing field, and even though two vendors have never verified that fact, I’m relatively certain that they all do. That’s the only way they could match to their own prior “only somewhat compatible” chip versions.

The net-net of this is that you may see some differences in matching segments at different vendors, even when you’re comparing the same people. Imputation generally “fills in the blanks,” but doesn’t create large swatches of non-existent DNA. I wrote about the concept of imputation here.

What I’d like for you to take away from this discussion is to be focused on the big picture – if and how people triangulate which is the function important to genealogy. Not if the start and end segments are exactly the same.

Triangulation Solutions

Each of the major vendors, except Ancestry who does not have a chromosome browser, offers some type of triangulation solution, so let’s look at what each vendor offers. If your Ancestry matches have uploaded to GedMatch, Family Tree DNA or MyHeritage, you can triangulate with them there. Otherwise, you can’t triangulate Ancestry results, so encourage your Ancestry matches to transfer.

I wrote more specifically about triangulation here and here.

Let’s start by looking at triangulation at MyHeritage.

Triangulation at MyHeritage

MyHeritage offers triangulation integrated into their chromosome browser.

Triangulation MyHeritage matches.png

At MyHeritage, select DNA Matches from the DNA dropdown menu, then click on the purple “Review DNA Match” of the person you want to compare. We re looking at my cousin, Cheryl F.

Triangulation MyHeritage review.png

When reviewing my DNA match with Cheryl, I can see the list of people that Cheryl and I both match, including my mother, first on the list. In addition to my mother’s relationship to me, I can also see an estimate of how closely my mother matches the other person – in this case, Cheryl. Cheryl is my mother’s first cousin (1C) and my first cousin, once removed (1C1R.)

Triangulation MyHeritage icon

Click to enlarge

For triangulation, the important image is the little purple icon at right, above.

Clicking on the purple triangulation icon shows the segments where Cheryl, my mother and I all three match and triangulate.

Finding my mother among Cheryl’s close matches tells me immediately which parent I share with Cheryl.

The areas on the chromosome browser below in the rounded squares are triangulated, meaning that I match Cheryl and the other person (who just happens to be my mother) on that same segment.

Triangulation MyHeritage browser.png

Showing triangulation with Cheryl and my mother provides a great example, because of course I triangulate with Cheryl and my mother on every segment where I match Cheryl – because I inherited all of those segments through my mother.

However, as far as triangulation goes, the fact that two of those people are closely related, me and my mother, makes it the same as only two people matching – Mom and Cheryl. Still, since Mom and Cheryl are first cousins, that match confirms my great-grandparents.

Cheryl carries pieces of my great-grandparent’s DNA that my mother doesn’t though, so matches in common with Cheryl may prove very genealogically useful.

At the top right of this chromosome browser page, I can “add or remove DNA matches” from my match list. I can look through my match list to find another close relative to see if they triangulate or I can download my match list to see who else matches me on that same segment. Instructions for the file download are at the end of this section.

Same Segment Matches

To illustrate that people will match you on the same segment, but don’t match each other because they descend from different sides of your family, I’ll add some cousins from my father’s side of the family.

I’m going to select cousins Charlene and David, and remove my mother.

Below, we show chromosome 3 again, but the triangulation bracket is gone. This tells us that this segment does NOT triangulate between me and ALL three people.

Please note that I may triangulate with some of the people. The absence of the bracket only means that I don’t triangulate with ALL of them.

I already know that while I match Cheryl, Charlene and David on this segment, only David and Charlene match each other because they are both from my father’s side, and Cheryl doesn’t match either of them because she is on my mother’s side.

Triangulation MyHeritage segments

To prove this, and to determine triangulation groups, I can compare the people two by two and continue adding people to see if they continue to triangulate.

Below, I’ve removed Cheryl, and I triangulate on chromosome 3 with both Charlene and David. The triangulation bracket appears.

Triangulation MyHeritage chromosome 3

Therefore, I know that Charlene and David descend through one of my parents, and Cheryl through the other – even if I didn’t know anything else at this point.

To reiterate, triangulation at MyHeritage means triangulation with everyone showing at the same time on the chromosome browser.

Other Resources to Identify Common Ancestors

For additional information, I can check the match information with each person to see if our trees, surnames or locations intersect.

SmartMatches and Theories of Family Relativity each provide clues and help to explain why we might triangulate.

SmartMatches tell you that you and another person share an ancestor in your and their tree, BUT, that common person may not be a direct ancestor of one or both of you. You also may or may not be DNA matches, and if so, your DNA match may or may not be through that ancestor.

Theories of Family Relativity (TOFR,) on the other hand, tell you that not only do you have a DNA match with this person, but that you have a common ancestor, and who that ancestor is. Sometimes the connection is made for you, even if one or both of you don’t show that ancestor in your tree simply because you have not extended your tree back far enough in time.

I wrote about how to use Theories of Family Relativity here.

Downloading Matches

You can request to download your matches list and also your shared DNA segments at MyHeritage by clicking on the three dots to the right at the top of your match list, then click on the option you wish. The resulting files will be e-mailed to you a few minutes later. If they don’t arrive, be sure to check your spam filter.

Triangulation MyHeritage export.png

Downloading your match list and/or shared DNA segments is NOT the same thing as downloading your raw data file to upload elsewhere. You’ll find those instructions in the Transfer section later in this article.

If not, click on Family Tree to create or upload one including not only direct line ancestors, but their children and grandchildren which facilitates and encourages the formation of Theories of Family Relativity.

Connecting Your DNA to Your Tree

Assigning your kit and those of family members to the proper profile card in your tree is very important, especially for the formation of Theories of Family Relativity

To suggest a theory, MyHeritage searches through all the possible links in the MyHeritage database meaning SmartMatches between trees, Record matches, record to record matches, etc.

If a DNA kit is not associated with an individual that is connected to ancestors, this reduces the probability that MyHeritage will be able to find a theory.

For example, if I took a DNA test but only have myself in the tree, not connected to my father and mother, but my father appears in another user’s tree (and there are more ancestors in that tree) MyHeritage won’t be able to find the information to generate a theory.

If I add my father, then the system has a common ancestor to work with.

When the TOFR algorithm runs, it’s trying to find any possible route to connect the two individuals (you and your DNA Match). If you are associated with individuals in multiple sites or trees, MyHeritage will try all of them and generate multiple paths for you to evaluate.

Have you assigned the kits of family members you manage to the proper place in your tree?

Triangulation MyHeritage tree.png

You can do this easily under the Manage DNA Kits option, under the DNA tab. Click on the three little dots to the right of the kit.

Triangulation MyHeritage assign dots.png

Then click assign the kit.

You’ll be prompted

If you start typing, you’ll be prompted with the names of people in your tree.

Other Resources to Identify Common Ancestors

MyHeritage includes other tools to help you identify common ancestors as well, including:

  • SmartMatches where MyHeritage matches individuals in trees
  • AutoClusters showing groups of people that match you and each other
  • Shared Matches indicating common DNA matches between you and another DNA match
  • Shared Ancestral Surnames show common surnames, even if a common ancestor does not show in a tree
  • Shared Ancestral Places indicating common locations in trees
  • Shared Ethnicities comparing ethnicity between matches, a feature typically only beneficial if looking for a minority (to you) ancestry match
  • Genealogical Records including matches from other databases such as Geni.com and FamilySearch
  • Trees

Transfers

Have you tested family members, especially everyone in the older generations? You can transfer their kits from Ancestry, 23andMe or FamilyTreeDNA if they’ve already tested there to MyHeritage.

The article, Are You DNA Testing the Right People? explains how to determine who to test. Make sure you aren’t missing anyone that you need.

Here’s how to transfer:

First Steps When Your DNA Results are Ready – Sticking Your Toe in the Genealogy Water

First steps helix

Recently someone asked me what the first steps would be for a person who wasn’t terribly familiar with genealogy and had just received their DNA test results.

I wrote an article called DNA Results – First Glances at Ethnicity and Matching which was meant to show new folks what the various vendor interfaces look like. I was hoping this might whet their appetites for more, meaning that the tester might, just might, stick their toe into the genealogy waters😊

I’m hoping this article will help them get hooked! Maybe that’s you!

A Guide

This article can be read in one of two ways – as an overview, or, if you click the links, as a pretty thorough lesson. If you’re new, I strongly suggest reading it as an overview first, then a second time as a deeper dive. Use it as a guide to navigate your results as you get your feet wet.

I’ll be hotlinking to various articles I’ve written on lots of topics, so please take a look at details (eventually) by clicking on those links!

This article is meant as a guideline for what to do, and how to get started with your DNA matching results!

If you’re looking for ethnicity information, check out the First Glances article, plus here and here and here.

Concepts – Calculating Ethnicity Percentages provides you with guidelines for how to estimate your own ethnicity percentages based on your known genealogy and Ethnicity Testing – A Conundrum explains how ethnicity testing is done.

OK, let’s get started. Fun awaits!

The Goal

The goal for using DNA matching in genealogy depends on your interests.

  1. To discover cousins and family members that you don’t know. Some people are interested in finding and meeting relatives who might have known their grandparents or great-grandparents in the hope of discovering new family information or photos they didn’t know existed previously. I’ve been gifted with my great-grandparent’s pictures, so this strategy definitely works!
  2. To confirm ancestors. This approach presumes that you’ve done at least a little genealogy, enough to construct at least a rudimentary tree. Ancestors are “confirmed” when you DNA match multiple other people who descend from the same ancestor through multiple children. I wrote an article, Ancestors: What Constitutes Proof?, discussing how much evidence is enough to actually confirm an ancestor. Confirmation is based on a combination of both genealogical records and DNA matching and it varies depending on the circumstances.
  3. Adoptees and people with unknown parents seeking to discover the identities of those people aren’t initially looking at their own family tree – because they don’t have one yet. The genealogy of others can help them figure out the identity of those mystery people. I wrote about that technique in the article, Identifying Unknown Parents and Individuals Using DNA Matching.

DNAAdoption for Everyone

Educational resources for adoptees and non-adoptees alike can be found at www.dnaadoption.org. DNAAdoption is not just for adoptees and provides first rate education for everyone. They also provide trained and mentored search angels for adoptees who understand the search process along with the intricacies of navigating the emotional minefield of adoption and unknown parent searches.

First Look” classes for each vendor are free for everyone at DNAAdoption and are self-paced, downloadable onto your computer as a pdf file. Intro to DNA, Applied Autosomal DNA and Y DNA Basics classes are nominally priced at between $29 and $49 and I strongly recommend these. DNAAdoption is entirely non-profit, so your class fee or contribution supports their work. Additional resources can be found here and their 12 adoptee search steps here.

Ok, now let’s look at your results.

Matches are the Key

Regardless of your goal, your DNA matches are the key to finding answers, whether you want to make contact with close relatives, prove your more distant ancestors or you’re involved in an adoptee or unknown parent search.

Your DNA matches that of other people because each of you inherited a piece of DNA, called a segment, where many locations are identical. The length of that DNA segment is measured in centiMorgans and those locations are called SNPs, or single nucleotide polymorphisms. You can read about the definition of a centimorgan and how they are used in the article Concepts – CentiMorgans, SNPs and Pickin’Crab.

While the scientific details are great, they aren’t important initially. What is important is to understand that the more closely you match someone, the more closely you are related to them. You share more DNA with close relatives than more distant relatives.

For example, I share exactly half of my mother’s DNA, but only about 25% of each of my grandparents’ DNA. As the relationships move further back in time, I share less and less DNA with other people who descend from those same ancestors.

Informational Tools

Every vendor’s match page looks different, as was illustrated in the First Glances article, but regardless, you are looking for four basic pieces of information:

  • Who you match
  • How much DNA you share with your match
  • Who else you and your match share that DNA with, which suggests that you all share a common ancestor
  • Family trees to reveal the common ancestor between people who match each other

Every vendor has different ways of displaying this information, and not all vendors provide everything. For example, 23andMe does not support trees, although they allow you to link to one elsewhere. Ancestry does not provide a tool called a chromosome browser which allows you to see if you and others match on the same segment of DNA. Ancestry only tells you THAT you match, not HOW you match.

Each vendor has their strengths and shortcomings. As genealogists, we simply need to understand how to utilize the information available.

I’ll be using examples from all 4 major vendors:

Your matches are the most important information and everything else is based on those matches.

Family Tree DNA

I have tested many family members from both sides of my family at Family Tree DNA using the Family Finder autosomal test which makes my matches there incredibly useful because I can see which family members, in addition to me, my matches match.

Family Tree DNA assigns matches to maternal and paternal sides in a unique way, even if your parents haven’t tested, so long as some close relatives have tested. Let’s take a look.

First Steps Family Tree DNA matches.png

Sign on to your account and click to see your matches.

At the top of your Family Finder matches page, you’ll see three groups of things, shown below.

First Steps Family Tree DNA bucketing

Click to enlarge

A row of tools at the top titled Chromosome Browser, In Common With and Not in Common With.

A second row of tabs that include All, Paternal, Maternal and Both. These are the maternal and paternal tabs I mentioned, meaning that I have a total of 4645 matches, 988 of which are from my paternal side and 847 of which are from my maternal side.

Family Tree DNA assigns people to these “buckets” based on matches with third cousins or closer if you have them attached in your tree. This is why it’s critical to have a tree and test close relatives, especially people from earlier generations like aunts, uncles, great-aunts/uncles and their children if they are no longer living.

If you have one or both parents that can test, that’s a wonderful boon because anyone who matches you and one of your parents is automatically bucketed, or phased (scientific term) to that parent’s side of the tree. However, at Family Tree DNA, it’s not required to have a parent test to have some matches assigned to maternal or paternal sides. You just need to test third cousins or closer and attach them to the proper place in your tree.

How does bucketing work?

Maternal or Paternal “Side” Assignment, aka Bucketing

If I match a maternal first cousin, Cheryl, for example, and we both match John Doe on the same segment, John Doe is automatically assigned to my maternal bucket with a little maternal icon placed beside the match.

First Steps Family Tree DNA match info

Click to enlarge

Every vendor provides an estimated or predicted relationship based on a combination of total centiMorgans and the longest contiguous matching segment. The actual “linked relationship” is calculated based on where this person resides in your tree.

The common surnames at far right are a very nice features, but not every tester provides that information. When the testers do include surnames at Family Tree DNA, common surnames are bolded. Other vendors have similar features.

People with trees are shown near their profile picture with a blue pedigree icon. Clicking on the pedigree icon will show you their ancestors. Your matches estimated relationship to you indicates how far back you should expect to share an ancestor.

For example, first cousins share grandparents. Second cousins share great-grandparents. In general, the further back in time your common ancestor, the less DNA you can be expected to share.

You can view relationship information in chart form in my article here or utilize DNAPainter tools, here, to see the various possibilities for the different match levels.

Clicking on the pedigree chart of your match will show you their tree. In my tree, I’ve connected my parents in their proper places, along with Cheryl and Don, mother’s first cousins. (Yes, they’ve given permission for me to utilize their results, so they aren’t always blurred in images.)

Cheryl and Don are my first cousins once removed, meaning my mother is their first cousin and I’m one generation further down the tree. I’m showing the amount of DNA that I share with each of them in red in the format of total DNA shared and longest unbroken segment, taken from the match list. So 382-53 means I share a total of 382 cM and 53 cM is the longest matching block.

First Steps Family Tree DNA tree.png

The Chromosome Browser

Utilizing the chromosome browser, I can see exactly where I match both Don and Cheryl. It’s obvious that I match them on at least some different pieces of my DNA, because the total and longest segment amounts are different.

The reason it’s important to test lots of close relatives is because even siblings inherit different pieces of DNA from their parents, and they don’t pass the same DNA to their offspring either – so in each generation the amount of shared DNA is probably reduced. I say probably because sometimes segments are passed entirely and sometimes not at all, which is how we “lose” our ancestors’ DNA over the generations.

Here’s a matching example utilizing a chromosome browser.

First Steps Family Tree DNA chromosome browser.png

I clicked the checkboxes to the left of both Cheryl and Don on the match page, then the Chromosome Browser button, and now you can see, above, on chromosomes 1-16 where I match Cheryl (blue) and Don (red.)

In this view, both Don and Cheryl are being compared to me, since I’m the one signed in to my account and viewing my DNA matches. Therefore, one of the bars at each chromosome represents Don’s DNA match to me and one represents Cheryl’s. Cheryl is the first person and Don is the second. Person match colors (red and blue) are assigned arbitrarily by the system.

My grandfather and Cheryl/Don’s father, Roscoe, were siblings.

You can see that on some segments, my grandfather and Roscoe inherited the same segment of DNA from their parents, because today, my mother gave me that exact same segment that I share with both Don and Cheryl. Those segments are exactly identical and shown in the black boxes.

The only way for us to share this DNA today is for us to have shared a common ancestor who gave it to two of their children who passed it on to their descendants who DNA tested today.

On other segments, in red boxes, I share part of the same segments of DNA with Cheryl and Don, but someone along the line didn’t inherit all of that segment. For example on chromosome 3, in the red box, you can see that I share more with Cheryl (blue) than Don (red.)

In other cases, I share with either Don or Cheryl, but Don and Cheryl didn’t inherit that same segment of DNA from their father, so I don’t share with both of them. Those are the areas where you see only blue or only red.

On chromosome 12, you can see where it looks like Don’s and Cheryl’s segments butt up against each other. The DNA was clearly divided there. Don received one piece and Cheryl got the other. That’s known as a crossover and you can read about crossovers here, if you’d like.

It’s important to be able to view segment information to be able to see how others match in order to identify which common ancestor that DNA came from.

In Common With

You can use the “In Common With” tool to see who you match in common with any match. My first 6 matches in common with Cheryl are shown below. Note that they are already all bucketed to my maternal side.

First Steps Family Tree DNA in common with

click to enlarge

You can click on up to 7 individuals in the check box at left to show them on the chromosome browser at once to see if they match you on common segments.

Each matching segment has its own history and may descend from a different ancestor in your common tree.

First Steps 7 match chromosome browser

click to enlarge

If combinations of people do match me on a common segment, because these matches are all on my maternal side, they are triangulated and we know they have to descend from a common ancestor, assuming the segment is large enough. You can read about the concept of triangulation here. Triangulation occurs when 3 or more people (who aren’t extremely closely related like parents or siblings) all match each other on the same reasonably sized segment of DNA.

If you want to download your matches and work through this process in a spreadsheet, that’s an option too.

Size Matters

Small segments can be identical by chance instead of identical by descent.

  • “Identical by chance” means that you accidentally match someone because your DNA on that segment has been combined from both parents and causes it to match another person, making the segment “looks like” it comes from a common ancestor, when it really doesn’t. When DNA is sequenced, both your mother and father’s strands are sequenced, meaning that there’s no way to determine which came from whom. Think of a street with Mom’s side and Dad’s side with identical addresses on the houses on both sides. I wrote about that here.
  • “Identical by descent” means that the DNA is identical because it actually descends from a common ancestor. I discussed that concept in the article, We Match, But Are We Related.

Generally, we only utilize 7cM (centiMorgan) segments and above because at that level, about half of the segments are identical by descent and about half are identical by chance, known as false positives. By the time we move above 15 cM, most, but not all, matches are legitimate. You can read about segment size and accuracy here.

Using “In Common With” and the Matrix

“In Common With” is about who shares DNA. You can select someone you match to see who else you BOTH match. Just because you match two other people doesn’t necessarily mean that it’s on the same segment of DNA. In fact, you could match one person from your mother’s side and the other person from your father’s side.

First Steps match matrix.png

In this example, you match Person B due to ancestor John Doe and Person C due to ancestor Susie Smith. However, Person B also matches person C, but due to ancestor William West that they share and you don’t.

This example shows you THAT they match, but not HOW they match.

The only way to assure that the matches between the three people above are due to the same ancestor is to look at the segments with a chromosome browser and compare all 3 people to each other. Finding 3 people who match on the same segment, from the same side of your tree means that (assuming a reasonably large segment) you share a common ancestor.

Family Tree DNA has a nice matrix function that allows you to see which of your matches also match each other.

First steps matrix link

click to enlarge

The important distinction between the matrix and the chromosome browser is that the chromosome browser shows you where your matches match you, but those matches could be from both sides of your tree, unless they are bucketed. The matrix shows you if your matches also match each other, which is a huge clue that they are probably from the same side of your tree.

First Steps Family Tree DNA matrix.png

A matrix match is a significant clue in terms of who descends from which ancestors. For example, I know, based on who Amy matches, and who she doesn’t match, that she descends from the Ferverda side and that Charles, Rex and Maxine descend from ancestors on the Miller side.

Looking in the chromosome browser, I can tell that Cheryl, Don, Amy and I match on some common segments.

Matching multiple people on the same segment that descends from a common ancestor is called triangulation.

Let’s take a look at the MyHeritage triangulation tool.

MyHeritage

Moving now to MyHeritage who provides us with an easy to use triangulation tool, we see the following when clicking on DNA matches on the DNA tab on the toolbar.

First Steps MyHeritage matches

click to enlarge

Cousin Cheryl is at MyHeritage too. By clicking on Review DNA Match, the purple button on the right, I can see who else I match in common with Cheryl, plus triangulation.

The list of people Cheryl and I both match is shown below, along with our relationships to each person.

First Steps MyHeritage triangulation

click to enlarge

I’ve selected 2 matches to illustrate.

The first match has a little purple icon to the right which means that Amy triangulates with me and Cheryl.

The second match, Rex, means that while we both match Rex, it’s not on the same segment. I know that without looking further because there is no triangulation button. We both match Rex, but Cheryl matches Rex on a different segment than I do.

Without additional genealogy work, using DNA alone, I can’t say whether or not Cheryl, Rex and I all share a common ancestor. As it turns out, we do. Rex is a known cousin who I tested. However, in an unknown situation, I would have to view the trees of those matches to make that determination.

Triangulation

Clicking on the purple triangulation icon for Amy shows me the segments that all 3 of us, me, Amy and Cheryl share in common as compared to me.

First Steps MyHeritage triangulation chromosome browser.png

Cheryl is red and Amy is yellow. The one segment bracketed with the rounded rectangle is the segment shared by all 3 of us.

Do we have a common ancestor? I know Cheryl and I do, but maybe I don’t know who Amy is. Let’s look at Amy’s tree which is also shown if I scroll down.

First Steps MyHeritage common ancestor.png

Amy didn’t have her tree built out far enough to show our common ancestor, but I immediately recognized the surname Ferveda found in her tree a couple of generations back. Darlene was the daughter of Donald Ferverda who was the son of Hiram Ferverda, my great-grandfather.

Hiram was the father of Cheryl’s father, Roscoe and my grandfather, John Ferverda.

First Steps Hiram Ferverda pedigree.png

Amy is my first cousin twice removed and that segment of DNA that I share with her is from either Hiram Ferverda or his wife Eva Miller.

Now, based on who else Amy matches, I can probably tell whether that segment descends from Hiram or Eva.

Viva triangulation!

Theory of Family Relativity

MyHeritage’s Theory of Family Relativity provides theories to people whose DNA matches regarding their common ancestor if MyHeritage can calculate how the 2 people are potentially related.

MyHeritage uses a combination of tools to make that connection, including:

  • DNA matches
  • Your tree
  • Your match’s tree
  • Other people’s trees at MyHeritage, FamilySearch and Geni if the common ancestor cannot be found in your tree compared against your DNA match’s MyHeritage
  • Documents in the MyHeritage data collection, such as census records, for example.

MyHeritage theory update

To view the Theories, click on the purple “View Theories” banner or “View theory” under the DNA match.

You can click on the “View Full Theory” to see the detail and sources about how MyHeritage calculated various paths. I have up to 5 different theories that utilize separate resources.

A wonderful aspect of this feature is that MyHeritage shows you exactly the information they utilized and calculates a confidence factor as well.

All theories should be viewed as exactly that and should be evaluated critically for accuracy, taking into consideration sources and documentation.

I wrote about using Theories of Relativity, with instructions, here and here.

I love this tool and find the Theories mostly accurate.

AncestryDNA

Ancestry doesn’t offer a chromosome browser or triangulation but does offer a tree view for people that you match, so long as you have a subscription. In the past, a special “Light” subscription for DNA only was available for approximately $49 per year that provided access to the trees of your DNA matches and other DNA-related features. You could not order online and had to call support, sometimes asking for a supervisor in order to purchase that reduced-cost subscription. The “Light” subscription did not provide access to anything outside of DNA results, meaning documents, etc. I don’t know if this is still available.

After signing on, click on DNA matches on the DNA tab on the toolbar.

You’ll see the following match list.

First Steps Ancestry matches

I’ve tested twice at Ancestry, the second time when they moved to their new chip, so I’m my own highest match. Click on any match name to view more.

First Steps Ancestry shared matches

You’ll see information about common ancestors if you have some in your trees, plus the amount of shared DNA along with a link to Shared Matches.

I found one of the same cousins at Ancestry whose match we were viewing at MyHeritage, so let’s see what her match to me at Ancestry looks like.

Below are my shared matches with that cousin. The notes to the right are mine, not provided by Ancestry. I make extensive use of the notes fields provided by the vendors.

First Steps Ancestry shared matches with cousin

On your match list, you can click on any match, then on Shared Matches to see who you both match in common. While Ancestry provides no chromosome browser, you can see the amount of DNA that you share and trees, if any exist.

Let’s look at a tree comparison when a common ancestor can be detected in a tree within the past 7 generations.

First Steps Ancestry view ThruLines.png

What’s missing of course is that I can’t see how we match because there’s no chromosome browser, nor can I see if my matches match each other.

Stitched Trees

What I can see, if I click on “View ThruLines” above or ThruLines on the DNA Summary page on the main DNA tab is all of the people I match who Ancestry THINKS we descend from a common ancestor. This ancestor information isn’t always taken from either person’s tree.

For example, if my match hadn’t included Hiram Ferverda in her tree, Ancestry would use other people’s trees to “stitch them together” such that the tester is shown to be descended from a common ancestor with me. Sometimes these stitched trees are accurate and sometimes they are not, although they have improved since they were first released. I wrote about ThruLines here.

First Steps Ancestry ThruLines tree

click to enlarge

In closer generations, especially if you are looking to connect with cousins, tree matching is a very valuable tool. In the graphic above, you can see all of the cousins who descend from Hiram Ferverda who have tested and DNA match to me. These DNA matches to me either descend from Hiram according to their trees, or Ancestry believes they descend from Hiram based on other people’s trees.

With more distant ancestors, other people’s trees are increasingly likely to be copied with no sources, so take them with a very large grain of salt (perchance the entire salt lick.) I use ThruLines as hints, not gospel, especially the further back in time the common ancestor. I wish they reached back another couple of generations. They are great hints and they end with the 7th generation where my brick walls tend to begin!

23andMe

I haven’t mentioned 23andMe yet in this article. Genealogists do test there, especially adoptees who need to fish in every pond.

23andMe is often the 4th choice of the major 4 vendors for genealogy due to the following challenges:

  • No tree support, other than allowing you to link to a tree at FamilySearch or elsewhere. This means no tree matching.
  • Less than 2000 matches, meaning that every person is limited to a maximum of 2000 matches, minus however many of those 2000 don’t opt-in for genealogical matching. Given that 23andMe’s focus is increasingly health, my number of matches continues to decrease and is currently just over 1500. The good news is that those 1500 are my highest, meaning closest matches. The bad news is the genealogy is not 23andMe’s focus.

If you are an adoptee, a die-hard genealogist or specifically interested in ethnicity, then test at 23andMe. Otherwise all three of the other vendors would be better choices.

However, like the other vendors, 23andMe does have some features that are unique.

Their ethnicity predictions are acknowledged to be excellent. Ethnicity at 23andMe is called Ancestry Composition, and you’ll see that immediately when you sign in to your account.

First Steps 23andMe DNA Relatives.png

Your matches at 23andMe are found under DNA Relatives.

First Steps 23andMe tools

click to enlarge

At left, you’ll find filters and the search box.

Mom’s and Dad’s side filter matches if you’ve tested your parents, but it’s not like the Family Tree DNA bucketing that provides maternal and paternal side bucketing by utilizing through third cousins if your parents aren’t available for testing.

Family names aren’t your family names, but the top family names that match to you. Guess what my highest name is? Smith.

However, Ancestor Birthplaces are quite useful because you can sort by country. For example, my mother’s grandfather Ferverda was born in the Netherlands.

First Steps 23andMe country.png

If I click on Netherlands, I can see my 5 matches with ancestors born in the Netherlands. Of course, this doesn’t mean that I match because of my match’s Dutch ancestors, but it does provide me with a place to look for a common ancestor and I can proceed by seeing who I match in common with those matches. Unfortunately, without trees we’re left to rely on ancestor birthplaces and family surnames, if my matches have entered that information.

One of my Dutch matches also matches my Ferverda cousin. Given that connection, and that the Ferverda family immigrated from Holland in 1868, that’s a starting point.

MyHeritage has a similar features and they are much more prevalent in Europe.

By clicking on my Ferverda cousin, I can view the DNA we share, who we match in common, our common ethnicity and more. I have the option of comparing multiple people in the chromosome browser by clicking on “View DNA Comparison” and then selecting who I wish to compare.

First Steps 23andMe view DNA Comparison.png

By scrolling down instead of clicking on View DNA Comparison, I can view where my Ferverda cousin matches me on my chromosomes, shown below.

First STeps 23andMe chromosome browser.png

23andMe identifies completely identical segments which would be painted in dark purple, the legend at bottom left.

Adoptees love this feature because it would immediately differentiate between half and full siblings. Full siblings share approximately 25% of the exact DNA on both their maternal and paternal strands of DNA, while half siblings only share the DNA from one parent – assuming their parents aren’t closely related. I share no completely identical DNA with my Ferverda cousin, so no segments are painted dark purple.

23andMe and Ancestry Maps Show Where Your Matches Live

Another reason that adoptees and people searching for birth parents or unknown relatives like 23andMe is because of the map function.

After clicking on DNA Relatives, click on the Map function at the top of the page which displays the following map.

First Steps 23andMe map

click to enlarge

This isn’t a map of where your matches ancestors lived, but is where your matches THEMSELVES live. Furthermore, you can zoom in, click on the button and it displays the name of the individual and the city where they live or whatever they entered in the location field.

First Steps 23andMe your location on map.png

I entered a location in my profile and confirmed that the location indeed displays on my match’s maps by signing on to another family member’s account. What I saw is the display above. I’d wager that most testers don’t realize that their home location and photo, if entered, is being displayed to their matches.

I think sharing my ancestors’ locations is a wonderful, helpful, idea, but there is absolutely no reason whatsoever for anyone to know where I live and I feel it’s stalker-creepy and a safety risk.

First Steps 23andMe questions.png

If you enter a location in this field in your profile, it displays on the map.

If you test with 23andMe and you don’t want your location to display on this map to your matches, don’t answer any question that asks you where you call home or anything similar. I never answer any questions at 23andMe. They are known for asking you the same question repeatedly, in multiple locations and ways, until you relent and answer.

Ancestry has a similar map feature and they’ve also begun to ask you questions that are unrelated to genealogy.

Ancestry Map Shows Where Your Matches Live

At Ancestry, when you click to see your DNA matches, look to the right at the map link.

First Steps Ancestry map link.png

By clicking on this link, you can see the locations that people have entered into their profile.

First Steps Ancestry match map.png

As you can see, above, I don’t have a location entered and I am prompted for one. Note that Ancestry does specifically say that this location will be shown to your matches.

You can click on the Ancestry Profile link here, or go to your Personal Profile by click the dropdown under your user name in the upper right hand corner of any page.

This is important because if you DON’T want your location to show, you need to be sure there is nothing entered in the location field.

Sometimes Your Answer is a Little More Complicated

This is a First Steps article. Sometimes the answer you seek might be a little more complicated. That’s why there are specialists who deal with this all day, everyday.

What issues might be more complex?

If you’re just starting out, don’t worry about these things for now. Just know when you run into something more complex or that doesn’t make sense, I’m here and so are others. Here’s a link to my Help page.

Getting Started

What do you need to get started?

  • You need to take a DNA test, or more specifically, multiple DNA tests. You can test at Ancestry or 23andMe and transfer your results to both Family Tree DNA and MyHeritage, or you can test directly at all vendors.

Neither Ancestry nor 23andMe accept uploads, meaning other vendors tests, but both MyHeritage and Family Tree DNA accept most file versions. Instructions for how to download and upload your DNA results are found below, by vendor:

Both MyHeritage and Family Tree DNA charge a minimal fee to unlock their advanced features such as chromosome browsers and ethnicity if you upload transfer files, but it’s less costly in both cases than testing directly. However, if you want the MyHeritage DNA plus Health or the Family Tree DNA Y DNA or Mitochondrial DNA tests, you must test directly at those companies for those tests.

  • It’s not required, but it would be in your best interest to build as much of a tree at all three vendors as you can. Every little bit helps.

Your first tree-building step should be to record what your family knows about your grandparents and great-grandparents, aunts and uncles. Here’s what my first step attempt looked like. It’s cringe-worthy now, but everyone has to start someplace. Just do it!

You can build a tree at either Ancestry or MyHeritage and download your tree for uploading at the other vendors. Or, you can build the tree using genealogy software on your computer and upload to all 3 places. I maintain my primary tree on my computer using RootsMagic. There are many options. MyHeritage even provides free tree builder software.

Both Ancestry and MyHeritage offer research/data subscriptions that provide you with hints to historical documents that increase what you know about your ancestors. The MyHeritage subscription can be tried for free. I have full subscriptions to both Ancestry and MyHeritage because they both include documents in their collections that the other does not.

Please be aware that document suggestions are hints and each one needs to be evaluated in the context of what you know and what’s reasonable. For example, if your ancestor was born in 1750, they are not included in the 1900 census, nor do women have children at age 70. People do have exactly the same names. FindAGrave information is entered by humans and is not always accurate. Just sayin’…

Evaluate critically and skeptically.

Ok, Let’s Go!

When your DNA results are ready, sign on to each vendor, look at your matches and use this article to begin to feel your way around. It’s exciting and the promise is immense. Feel free to share the link to this article on social media or with anyone else who might need help.

You are the cumulative product of your ancestors. What better way to get to know them than through their DNA that’s shared between you and your cousins!

What can you discover today?

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!!!

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.

DNA at MyHeritage Theories of Family Relativity
Transferred prior to Dec. 16, 2018 Free
Transferred since Dec. 16, 2018 $29 unlock per kit or subscription
