DNA Testing and Transfers – What’s Your Strategy?

The landscape of genetic genealogy is forever morphing.

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

Come join in the fun!

Testing and Transfer Strategy

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

DNA Vendor Transfer Chart 2019

Click on image to enlarge.

Caveats and footnotes as follows:

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

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

Recommendations

My recommendations are as follows, and why:

Transfer Costs

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

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

All great values!

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

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

Full or Half Siblings?

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

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

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

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

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

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

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

Half Siblings Versus Step-Siblings

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

Parental Testing

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

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

Ranges Aren’t Perfect

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

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

Why?

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

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

Sibling shared cM chart 2016.png

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

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

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

Sibling shared cM DNAPainter.png

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

Full or Half Siblings?

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

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

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

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

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

Total Number of Shared cM

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

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

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

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

Fully Identical and Half Identical Regions

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

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

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

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

Understanding the Concept of Half Identical Versus Fully Identical

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

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

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

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

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

Sibling full vs half 8 siblings arrows

This chart illustrates the concept of matching where siblings share:

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

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

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

Ancestry

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

Sibling Ancestry.png

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

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

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

A big thank you to my colleague!

MyHeritage

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

Sibling MyHeritage.png

Family Tree DNA

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

Sibling FamilyTreeDNA.png

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

Sibling advanced matches.png

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

Sibling bucketing both.png

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

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

GedMatch

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

Sibling GedMatch menu.png

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

Sibling GedMatch total.png

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

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

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

Sibling GedMatch legend.png

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

Sibling GedMatch FIR.png

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

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

Sibling GedMatch HIR.png

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

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

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

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

Twins

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

Sibling GedMatch identical twin.png

Here’s the same chart for identical twins.

23andMe

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

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

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

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

Sibling 23andMe HIR.png

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

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

Sibling 23andMe FIR.png

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

Unusual Circumstances

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

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

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

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

The Final SafeGuard – Just in Case

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

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

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

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

Sibling both sides matching.png

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

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

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

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

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

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

In the End

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

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

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

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

MyHeritage’s New Theory of Family Relativity

2019 Theory of Family Relativity

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

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

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

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

Documents include the entire library of MyHeritage resources.

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

Are Theories Accurate?

I have a total of 51 matches with theories.

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

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

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

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

How Does the Theory of Family Relativity Work?

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

Theory Big Tree

They describe the Big Tree thus:

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

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

Finding the Theories

Sign on to your account and click on DNA.

Theory of Family Relativity

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

Theory finding

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

Evaluating Theories

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

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

Theory multiple

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

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

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

Theory 2 theories

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

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

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

Match 1 – Known First Cousin

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

Theory match 1

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

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

Match 1 – Path 1

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

Theory match 1 path 1

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

This happens to be correct.

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

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

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

theory Ferverda profile

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

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

Match 1 – Path 2

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

Theory match 1 path 2.png

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

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

Theory match 1 path 2 profile.png

Match 1 – Path 3

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

Theory match 1 path 3.png

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

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

Theory match 1 path 3 review.png

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

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

Theory 1 match 3 profile.png

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

Match 1 Conclusion

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

Match 1 Suggestions

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

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

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

Theory census.png

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

Match 2 – Known Half Niece

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

There are two ways to reach theories.

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

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

Theory match 2.png

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

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

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
Tested at MyHeritage Subscription

23andMe Step by Step Guide: How to Upload-Download DNA Files

In this Upload-Download series, we’ll cover each major vendor:

  • How to download raw data files from the vendor
  • How to upload raw data files to the vendor, if possible
  • Other mainstream vendors where you can upload this vendor’s files

Uploading TO 23andMe

This part is easy with 23andMe, because 23andMe doesn’t accept any other vendor’s files. There is no ability to upload TO 23andMe. You have to test with 23andMe if you want results from 23andMe.

Downloading FROM 23andMe

In order to transfer your autosomal DNA file to another testing vendor, or GedMatch, for either matching or ethnicity, you’ll need to first download the file from 23andMe.

Download Step 1

Sign on to your account at 23andMe.

23andMe download

Under your name at the upper right-hand corner of your page, by clicking on the little circle with your initials, you’ll see “Browse Raw Data.” Click there.

Download Step 2

23andMe download 2

You’ll see “Your Raw Data.” Click on the blue download link.

Download Step 3

On the Download Raw Data page, scroll down towards the bottom until you see “Request your raw data download.”

23andMe download 3

Click on Submit request.

Download Step 4

You’ll see the following message saying an e-mail will be sent to you.

23andMe download 4

Download Step 5

A few minutes later, an e-mail will arrive that says this:

23andMe download 5

Click on the green button in the e-mail which will take you back to 23andMe to sign in.

Download Step 6

After you sign in, you’ll be immediately at the download page and will see the following.

23andMe download 6

Your raw data file will be downloaded to your computer where you’ll need to store it in a location and by a name that you can find.

The file name will be something like “genome_Roberta_Estes_v2_v3_Full_xxxxxxxx” where the xs are a long number. I would suggest adding the word 23andMe to the front when you save the file on your system.

Most vendors want an unopened zip file, so if you want to open your file, first copy it to another name. Otherwise, you’ll have to download again.

23andMe File Transfers to Other Vendors

23andMe files can be in one any one of four formats:

  • V2 – the earliest tests taken at 23andMe. V2 test takers were offered an upgrade to V3.
  • V3 – V3 files beginning December 2010 through December 2013
  • V4 – V4 files beginning December 2013 through August 2017
  • V5 – V5 files beginning August 2017 through present

The changes in the files due to chip differences sometimes cause issues with transfers to other vendors who utilize other testing chips.

Your upload results to other vendors’ sites will vary in terms of both matching and ethnicity accuracy based on your 23andMe version number, as follows:

From below to >>>>>>> Family Tree DNA Accepts * MyHeritage Accepts** GedMatch Accepts *** Ancestry Accepts LivingDNA Accepts ****
23andMe V2 No Yes Yes No Yes
23andMe V3 Yes, fully compatible Yes Yes No Yes
23andMe V4 Yes, partly compatible Yes Yes No Yes
23andMe V5 No Yes Yes No Yes

* The transfer to Family Tree DNA and matching is free, but advanced tools including the chromosome browser and ethnicity require a one-time $19 unlock fee. That fee is less expensive than retesting, but V4 customers should consider retesting to obtain fully compatible matching. V4 tests won’t receive all of the distant matches that they would if they tested at Family Tree DNA

** MyHeritage  and Family Tree DNA use the same testing chip, but MyHeritage utilizes a technique known as imputation to achieve compatibility between different vendors files. The transfer and matching is free, but advanced tools require a one-time $29 unlock fee unless you are a MyHeritage subscriber. You can read about the various options here.

***GedMatch recently transitioned to their Genesis platform and is still working on matching between multiple vendors highly disparate chips with little overlapping test regions. Patience is key. Matching is free, but the more advanced features require a Tier 1 subscription for $10 per month.

**** LivingDNA accepts files, but their matching is still in an early testing phase. They have also just changed DNA testing chips so the net effect is unknown. I will review their features later in 2019.

23andMe Testing and Transfer Strategy

My recommendation, if you’ve tested at 23andMe, depending on your test version, is as follows:

  • V2 – Upgrade (retest) at 23andMe to newer test version.
  • V3 – Transfer to Family Tree DNA, MyHeritage and GedMatch
  • V4 or V5 – Test at either Family Tree DNA or MyHeritage and transfer to the other one. You never know which match is going to break down that brick wall, and it would be a shame to miss it because you transferred rather than retested.

Combined DNA Matches + Tree Matches at MyHeritage

In the 2018 year in review article I wrote a couple days ago, a reader commented that they didn’t realize that MyHeritage had combined DNA matching with tree matching.

They have and it’s super easy.

DNA and Tree Matching in 4 Easy Steps

Here’s how to see your combined matches in 4 short steps.

  1. Sign on and click on DNA Matches.

  1. Click on the little filter icon.

  1. Click on “All tree details.”

  1. Then, click on “Has Smart Matches.”

That’s it!

DNA Matches Plus SmartMatches

Voila – using this filter setting, the only matches you will see are your DNA matches that are also SmartMatches, meaning the other person shares a common ancestor (or more) in a tree with you. You’ll see a combination of both features. We’ll use my match with Michael as an example.

Scroll down to review all of your information in common with this match including:

  • Summary Information (estimated relationship, % match, shared cM match, number of shared segments, largest segment in cM,)

  • Shared Ancestors

  • Shared Ancestral Surnames

  • Shared Ancestral Places

  • Shared DNA Matches, including triangulation indicated by the purple circled segment icon at right

MIchael matches my mother too, so if I didn’t already know which parental side Michael matched me on, I do now. Triangulating with multiple other relatives assures me of a valid match.

  • Pedigree charts

  • Shared Ethnicities

  • Chromosome Browser – Shared DNA Segments

Who do you match, share ancestors and triangulate with?

Testing at or Transferring to MyHeritage

You can either test at MyHeritage or transfer a DNA file from other vendors to MyHeritage.

2018 – The Year of the Segment

Looking in the rear view mirror, what a year! Some days it’s been hard to catch your breath things have been moving so fast.

What were the major happenings, how did they affect genetic genealogy and what’s coming in 2019?

The SNiPPY Award

First of all, I’m giving an award this year. The SNiPPY.

Yea, I know it’s kinda hokey, but it’s my way of saying a huge thank you to someone in this field who has made a remarkable contribution and that deserves special recognition.

Who will it be this year?

Drum roll…….

The 2018 SNiPPY goes to…

DNAPainter – The 2018 SNiPPY award goes to DNAPainter, without question. Applause, everyone, applause! And congratulations to Jonny Perl, pictured below at Rootstech!

Jonny Perl created this wonderful, visual tool that allows you to paint your matches with people on your chromosomes, assigning the match to specific ancestors.

I’ve written about how to use the tool  with different vendors results and have discovered many different ways to utilize the painted segments. The DNA Painter User Group is here on Facebook. I use DNAPainter EVERY SINGLE DAY to solve a wide variety of challenges.

What else has happened this year? A lot!

Ancient DNA – Academic research seldom reports on Y and mitochondrial DNA today and is firmly focused on sequencing ancient DNA. Ancient genome sequencing has only recently been developed to a state where at least some remains can be successfully sequenced, but it’s going great guns now. Take a look at Jennifer Raff’s article in Forbes that discusses ancient DNA findings in the Americas, Europe, Southeast Asia and perhaps most surprising, a first generation descendant of a Neanderthal and a Denisovan.

From Early human dispersals within the Americas by Moreno-Mayer et al, Science 07 Dec 2018

Inroads were made into deeper understanding of human migration in the Americas as well in the paper Early human dispersals within the Americas by Moreno-Mayer et al.

I look for 2019 and on into the future to hold many more revelations thanks to ancient DNA sequencing as well as using those sequences to assist in understanding the migration patterns of ancient people that eventually became us.

Barbara Rae-Venter and the Golden State Killer Case

Using techniques that adoptees use to identify their close relatives and eventually, their parents, Barbara Rae-Venter assisted law enforcement with identifying the man, Joseph DeAngelo, accused (not yet convicted) of being the Golden State Killer (GSK).

A very large congratulations to Barbara, a retired patent attorney who is also a genealogist. Nature recognized Ms. Rae-Venter as one of 2018’s 10 People Who Mattered in Science.

DNA in the News

DNA is also represented on the 2018 Nature list by Viviane Slon, a palaeogeneticist who discovered an ancient half Neanderthal, half Denisovan individual and sequenced their DNA and He JianKui, a Chinese scientist who claims to have created a gene-edited baby which has sparked widespread controversy. As of the end of the year, He Jiankui’s research activities have been suspended and he is reportedly sequestered in his apartment, under guard, although the details are far from clear.

In 2013, 23andMe patented the technology for designer babies and I removed my kit from their research program. I was concerned at the time that this technology knife could cut two ways, both for good, eliminating fatal disease-causing mutations and also for ethically questionable practices, such as eugenics. I was told at the time that my fears were unfounded, because that “couldn’t be done.” Well, 5 years later, here we are. I expect the debate about the ethics and eventual regulation of gene-editing will rage globally for years to come.

Elizabeth Warren’s DNA was also in the news when she took a DNA test in response to political challenges. I wrote about what those results meant scientifically, here. This topic became highly volatile and politicized, with everyone seeming to have a very strongly held opinion. Regardless of where you fall on that opinion spectrum (and no, please do not post political comments as they will not be approved), the topic is likely to surface again in 2019 due to the fact that Elizabeth Warren has just today announced her intention to run for President. The good news is that DNA testing will likely be discussed, sparking curiosity in some people, perhaps encouraging them to test. The bad news is that some of the discussion may be unpleasant at best, and incorrect click-bait at worst. We’ve already had a rather unpleasant sampling of this.

Law Enforcement and Genetic Genealogy

The Golden State Killer case sparked widespread controversy about using GedMatch and potentially other genetic genealogy data bases to assist in catching people who have committed violent crimes, such as rape and murder.

GedMatch, the database used for the GSK case has made it very clear in their terms and conditions that DNA matches may be used for both adoptees seeking their families and for other uses, such as law enforcement seeking matches to DNA sequenced during a criminal investigation. Since April 2018, more than 15 cold case investigations have been solved using the same technique and results at GedMatch. Initially some people removed their DNA from GedMatch, but it appears that the overwhelming sentiment, based on uploads, is that people either aren’t concerned or welcome the opportunity for their DNA matches to assist apprehending criminals.

Parabon Nanolabs in May established a genetic genealogy division headed by CeCe Moore who has worked in the adoptee community for the past several years. The division specializes in DNA testing forensic samples and then assisting law enforcement with the associated genetic genealogy.

Currently, GedMatch is the only vendor supporting the use of forensic sample matching. Neither 23anMe nor Ancestry allow uploaded data, and MyHeritage and Family Tree DNA’s terms of service currently preclude this type of use.

MyHeritage

Wow talk about coming onto the DNA world stage with a boom.

MyHeritage went from a somewhat wobbly DNA start about 2 years ago to rolling out a chromosome browser at the end of January and adding important features such as SmartMatching which matches your DNA and your family trees. Add triangulation to this mixture, along with record matching, and you’re got a #1 winning combination.

It was Gilad Japhet, the MyHeritage CEO who at Rootstech who christened 2018 “The Year of the Segment,” and I do believe he was right. Additionally, he announced that MyHeritage partnered with the adoption community by offering 15,000 free kits to adoptees.

In November, MyHeritage hosted MyHeritage LIVE, their first user conference in Oslo, Norway which focused on both their genealogical records offerings as well as DNA. This was a resounding success and I hope MyHeritage will continue to sponsor conferences and invest in DNA. You can test your DNA at MyHeritage or upload your results from other vendors (instructions here). You can follow my journey and the conference in Olso here, here, here, here and here.

GDPR

GDPR caused a lot of misery, and I’m glad the implementation is behind us, but the the ripples will be affecting everyone for years to come.

GDPR, the European Data Protection Regulation which went into effect on May 25,  2018 has been a mixed and confusing bag for genetic genealogy. I think the concept of users being in charge and understanding what is happened with their data, and in this case, their data plus their DNA, is absolutely sound. The requirements however, were created without any consideration to this industry – which is small by comparison to the Googles and Facebooks of the world. However, the Googles and Facebooks of the world along with many larger vendors seem to have skated, at least somewhat.

Other companies shut their doors or restricted their offerings in other ways, such as World Families Network and Oxford Ancestors. Vendors such as Ancestry and Family Tree DNA had to make unpopular changes in how their users interface with their software – in essence making genetic genealogy more difficult without any corresponding positive return. The potential fines, 20 million plus Euro for any company holding data for EU residents made it unwise to ignore the mandates.

In the genetic genealogy space, the shuttering of both YSearch and MitoSearch was heartbreaking, because that was the only location where you could actually compare Y STR and mitochondrial HVR1/2 results. Not everyone uploaded their results, and the sites had not been updated in a number of years, but the closure due to GDPR was still a community loss.

Today, mitoydna.org, a nonprofit comprised of genetic genealogists, is making strides in replacing that lost functionality, plus, hopefully more.

On to more positive events.

Family Tree DNA

In April, Family Tree DNA announced a new version of the Big Y test, the Big Y-500 in which at least 389 additional STR markers are included with the Big Y test, for free. If you’re lucky, you’ll receive between 389 and 439 new markers, depending on how many STR markers above 111 have quality reads. All customers are guaranteed a minimum of 500 STR markers in total. Matching was implemented in December.

These additional STR markers allow genealogists to assemble additional line marker mutations to more granularly identify specific male lineages. In other words, maybe I can finally figure out a line marker mutation that will differentiate my ancestor’s line from other sons of my founding ancestor😊

In June, Family Tree DNA announced that they had named more than 100,000 SNPs which means many haplogroup additions to the Y tree. Then, in September, Family Tree DNA published their Y haplotree, with locations, publicly for all to reference.

I was very pleased to see this development, because Family Tree DNA clearly has the largest Y database in the industry, by far, and now everyone can reap the benefits.

In October, Family Tree DNA published their mitochondrial tree publicly as well, with corresponding haplogroup locations. It’s nice that Family Tree DNA continues to be the science company.

You can test your Y DNA, mitochondrial or autosomal (Family Finder) at Family Tree DNA. They are the only vendor offering full Y and mitochondrial services complete with matching.

2018 Conferences

Of course, there are always the national conferences we’re familiar with, but more and more, online conferences are becoming available, as well as some sessions from the more traditional conferences.

I attended Rootstech in Salt Lake City in February (brrrr), which was lots of fun because I got to meet and visit with so many people including Mags Gaulden, above, who is a WikiTree volunteer and writes at Grandma’s Genes, but as a relatively expensive conference to attend, Rootstech was pretty miserable. Rootstech has reportedly made changes and I hope it’s much better for attendees in 2019. My attendance is very doubtful, although I vacillate back and forth.

On the other hand, the MyHeritage LIVE conference was amazing with both livestreamed and recorded sessions which are now available free here along with many others at Legacy Family Tree Webinars.

Family Tree University held a Virtual DNA Conference in June and those sessions, along with others, are available for subscribers to view.

The Virtual Genealogical Association was formed for those who find it difficult or impossible to participate in local associations. They too are focused on education via webinars.

Genetic Genealogy Ireland continues to provide their yearly conference sessions both livestreamed and recorded for free. These aren’t just for people with Irish genealogy. Everyone can benefit and I enjoy them immensely.

Bottom line, you can sit at home and educate yourself now. Technology is wonderful!

2019 Conferences

In 2019, I’ll be speaking at the National Genealogical Society Family History Conference, Journey of Discovery, in St. Charles, providing the Special Thursday Session titled “DNA: King Arthur’s Mighty Genetic Lightsaber” about how to use DNA to break through brick walls. I’ll also see attendees at Saturday lunch when I’ll be providing a fun session titled “Twists and Turns in the Genetic Road.” This is going to be a great conference with a wonderful lineup of speakers. Hope to see you there.

There may be more speaking engagements at conferences on my 2019 schedule, so stay tuned!

The Leeds Method

In September, Dana Leeds publicized The Leeds Method, another way of grouping your matches that clusters matches in a way that indicates your four grandparents.

I combine the Leeds method with DNAPainter. Great job Dana!

Genetic Affairs

In December, Genetic Affairs introduced an inexpensive subscription reporting and visual clustering methodology, but you can try it for free.

I love this grouping tool. I have already found connections I didn’t know existed previously. I suggest joining the Genetic Affairs User Group on Facebook.

DNAGedcom.com

I wrote an article in January about how to use the DNAGedcom.com client to download the trees of all of your matches and sort to find specific surnames or locations of their ancestors.

However, in December, DNAGedcom.com added another feature with their new DNAGedcom client just released that downloads your match information from all vendors, compiles it and then forms clusters. They have worked with Dana Leeds on this, so it’s a combination of the various methodologies discussed above. I have not worked with the new tool yet, as it has just been released, but Kitty Cooper has and writes about it here.  If you are interested in this approach, I would suggest joining the Facebook DNAGedcom User Group.

Rootsfinder

I have not had a chance to work with Rootsfinder beyond the very basics, but Rootsfinder provides genetic network displays for people that you match, as well as triangulated views. Genetic networks visualizations are great ways to discern patterns. The tool creates match or triangulation groups automatically for you.

Training videos are available at the website and you can join the Rootsfinder DNA Tools group at Facebook.

Chips and Imputation

Illumina, the chip maker that provides the DNA chips that most vendors use to test changed from the OmniExpress to the GSA chip during the past year. Older chips have been available, but won’t be forever.

The newer GSA chip is only partially compatible with the OmniExpress chip, providing limited overlap between the older and the new results. This has forced the vendors to use imputation to equalize the playing field between the chips, so to speak.

This has also caused a significant hardship for GedMatch who is now in the position of trying to match reasonably between many different chips that sometimes overlap minimally. GedMatch introduced Genesis as a sandbox beta version previously, but are now in the process of combining regular GedMatch and Genesis into one. Yes, there are problems and matching challenges. Patience is the key word as the various vendors and GedMatch adapt and improve their required migration to imputation.

DNA Central

In June Blaine Bettinger announced DNACentral, an online monthly or yearly subscription site as well as a monthly newsletter that covers news in the genetic genealogy industry.

Many educators in the industry have created seminars for DNACentral. I just finished recording “Getting the Most out of Y DNA” for Blaine.

Even though I work in this industry, I still subscribed – initially to show support for Blaine, thinking I might not get much out of the newsletter. I’m pleased to say that I was wrong. I enjoy the newsletter and will be watching sessions in the Course Library and the Monthly Webinars soon.

If you or someone you know is looking for “how to” videos for each vendor, DNACentral offers “Now What” courses for Ancestry, MyHeritage, 23andMe, Family Tree DNA and Living DNA in addition to topic specific sessions like the X chromosome, for example.

Social Media

2018 has seen a huge jump in social media usage which is both bad and good. The good news is that many new people are engaged. The bad news is that people often given faulty advice and for new people, it’s very difficult (nigh on impossible) to tell who is credible and who isn’t. I created a Help page for just this reason.

You can help with this issue by recommending subscribing to these three blogs, not just reading an article, to newbies or people seeking answers.

Always feel free to post links to my articles on any social media platform. Share, retweet, whatever it takes to get the words out!

The general genetic genealogy social media group I would recommend if I were to select only one would be Genetic Genealogy Tips and Techniques. It’s quite large but well-managed and remains positive.

I’m a member of many additional groups, several of which are vendor or interest specific.

Genetic Snakeoil

Now the bad news. Everyone had noticed the popularity of DNA testing – including shady characters.

Be careful, very VERY careful who you purchase products from and where you upload your DNA data.

If something is free, and you’re not within a well-known community, then YOU ARE THE PRODUCT. If it sounds too good to be true, it probably is. If it sounds shady or questionable, it’s probably that and more, or less.

If reputable people and vendors tell you that no, they really can’t determine your Native American tribe, for example, no other vendor can either. Just yesterday, a cousin sent me a link to a “tribe” in Canada that will, “for $50, we find one of your aboriginal ancestors and the nation stamps it.” On their list of aboriginal people we find one of my ancestors who, based on mitochondrial DNA tests, is clearly NOT aboriginal. Snake oil comes in lots of flavors with snake oil salesmen looking to prey on other people’s desires.

When considering DNA testing or transfers, make sure you fully understand the terms and conditions, where your DNA is going, who is doing what with it, and your recourse. Yes, read every single word of those terms and conditions. For more about legalities, check out Judy Russell’s blog.

Recommended Vendors

All those DNA tests look yummy-good, but in terms of vendors, I heartily recommend staying within the known credible vendors, as follows (in alphabetical order).

For genetic genealogy for ethnicity AND matching:

  • 23andMe
  • Ancestry
  • Family Tree DNA
  • GedMatch (not a vendor because they don’t test DNA, but a reputable third party)
  • MyHeritage

You can read about Which DNA Test is Best here although I need to update this article to reflect the 2018 additions by MyHeritage.

Understand that both 23andMe and Ancestry will sell your DNA if you consent and if you consent, you will not know who is using your DNA, where, or for what purposes. Neither Family Tree DNA, GedMatch, MyHeritage, Genographic Project, Insitome, Promethease nor LivingDNA sell your DNA.

The next group of vendors offers ethnicity without matching:

  • Genographic Project by National Geographic Society
  • Insitome
  • LivingDNA (currently working on matching, but not released yet)

Health (as a consumer, meaning you receive the results)

Medical (as a contributor, meaning you are contributing your DNA for research)

  • 23andMe
  • Ancestry
  • DNA.Land (not a testing vendor, doesn’t test DNA)

There are a few other niche vendors known for specific things within the genetic genealogy community, many of whom are mentioned in this article, but other than known vendors, buyer beware. If you don’t see them listed or discussed on my blog, there’s probably a reason.

What’s Coming in 2019

Just like we couldn’t have foreseen much of what happened in 2018, we don’t have access to a 2019 crystal ball, but it looks like 2019 is taking off like a rocket. We do know about a few things to look for:

  • MyHeritage is waiting to see if envelope and stamp DNA extractions are successful so that they can be added to their database.
  • www.totheletterDNA.com is extracting (attempting to) and processing DNA from stamps and envelopes for several people in the community. Hopefully they will be successful.
  • LivingDNA has been working on matching since before I met with their representative in October of 2017 in Dublin. They are now in Beta testing for a few individuals, but they have also just changed their DNA processing chip – so how that will affect things and how soon they will have matching ready to roll out the door is unknown.
  • Ancestry did a 2018 ethnicity update, integrating ethnicity more tightly with Genetic Communities, offered genetic traits and made some minor improvements this year, along with adding one questionable feature – showing your matches the location where you live as recorded in your profile. (23andMe subsequently added the same feature.) Ancestry recently said that they are promising exciting new tools for 2019, but somehow I doubt that the chromosome browser that’s been on my Christmas list for years will be forthcoming. Fingers crossed for something new and really useful. In the mean time, we can download our DNA results and upload to MyHeritage, Family Tree DNA and GedMatch for segment matching, as well as utilize Ancestry’s internal matching tools. DNA+tree matching, those green leaf shared ancestor hints, is still their strongest feature.
  • The Family Tree DNA Conference for Project Administrators will be held March 22-24 in Houston this year, and I’m hopeful that they will have new tools and announcements at that event. I’m looking forward to seeing many old friends in Houston in March.

Here’s what I know for sure about 2019 – it’s going to be an amazing year. We as a community and also as individual genealogists will be making incredible discoveries and moving the ball forward. I can hardly wait to see what quandaries I’ve solved a year from now.

What mysteries do you want to unravel?

I’d like to offer a big thank you to everyone who made 2018 wonderful and a big toast to finding lots of new ancestors and breaking down those brick walls in 2019.

Happy New Year!!!

Free MyHeritage LIVE 2018 Webinars Are Online

MyHeritage LIVE 2018 webinars

For everyone that has been waiting for the MyHeritage LIVE 2018 webinars, they are available free at Legacy Family Tree Webinars, here.

One really nice thing MyHeritage did was to include the actual speaker’s slides on the left side of the screen, with the speaker shown to the right. This means that you’re going to be able to see the slides better than many people attending the conference.

I spy several that I need to watch – like learning more about the MyHeritage Mobile App, Newspaper Research strategies and how to more effectively use SuperSearch.

I mostly attended the DNA sessions, so I need to watch the genealogy ones online.

I do have a recommendation for you though.

Gilad Japhet’s keynote was incredible. So inspirational, powerful and moving – in a way that all genealogists can relate to. Riveting is the word that comes to mind. You could have heard a pin drop.

The great thing is that Gilad is making the changes happen in how records are searched and indexed at MyHeritage that will benefit his own research – and ours too, right along with his. Not to mention leading edge genetic technology like extracting DNA from envelopes and stamps. The jury is still out on this, so stay tuned.

Happy Holidays to You

You can give yourself an early (free) holiday present by setting time aside to watch these information-filled sessions.

There are a total of 18 free sessions from the conference and another 27 free classes about how to use MyHeritage for a total of 45.

Make yourself a list of the sessions you’d like to watch and watch one a day – sort of a genealogical version of the 45 days of Christmas😊

Of course, genealogy research works much better if it includes DNA testing.

Upload Your DNA

Don’t forget that DNA uploads and tools are free at MyHeritage until December 1, but after that there will be a cost for their advanced tools. Anyone who tests there or uploads before December 1 will be grandfathered in for free. That’s just 2 more days so don’t wait!

Click here to upload your DNA for free.

I wrote step-by-step instructions here for downloading your DNA from other sites and uploading to MyHeritage.

Test Your DNA

If you haven’t tested your DNA, order a test now by clicking here while the holidays sales are in full force.

End of Free DNA Uploads to MyHeritage November 30th

5 day countdown

You have just 5 more days to upload your autosomal DNA raw data files from other sites to MyHeritage for entirely free. As of December 1st, MyHeritage is changing their pricing model for uploads and a charge of some sort will be put in place for the more advanced tools.

MyHeritage hasn’t said exactly what that charge will be, whether it will be a one time unlock or a subscription of some sort.

What they HAVE said is that anyone who transfers DNA from any of the other major vendors before December 1st or has transferred in the past will have free access to all of the DNA tools.

Here’s the exact quote from their blog:

As of December 1, 2018, our policy regarding DNA uploads will change: DNA Matching will remain free for uploaded DNA data, but unlocking additional DNA features (for example, ethnicity estimate, chromosome browser, and some others) will require an extra payment for DNA files uploaded after this date. We will announce the full details of the new policy once it is finalized, closer to December 1st. All DNA data that was uploaded to MyHeritage in the past, and all DNA data that is uploaded now and prior to December 1, 2018, will continue to enjoy full access to all DNA features for free. These uploads will be grandfathered in and will remain free.

You can upload multiple files from different people to be managed under one account at MyHeritage. For example, I manage several kits for multiple family members. The e-mails have been flying back and forth the past several days as I’ve been requesting permission to do the free uploads by the end of November. If your family member opens a MyHeritage account someday, you can transfer their results to them – no problem.

You can transfer Ancestry, Family Tree DNA, 23andMe and LivingDNA raw DNA files.

So, click here to upload now while uploads and all tools are still free.

Need help? No problem!

Step-By-Step Upload Instructions

I wrote a step by step guide for how to upload to MyHeritage here, including steps to download from other vendors in the article MyHeritage Step by Step Guide How to Upload-Download DNA Files.

If you haven’t uploaded yet, or have family members whose files you manage that you haven’t uploaded, you don’t want to wait. The clock is tick-tocking! Upload now so you don’t forget like I almost did.

Lydia Brown’s 3 Daughters: Or Were They? Mitochondrial and Autosomal DNA to the Rescue – 52 Ancestors #218

There has long been speculation about what happened to Lydia Brown, the wife of William Crumley III, and when.

It doesn’t help a bit that William Crumley, her husband, was actually William Crumley the third, being named for both his father and grandfather.

William Crumley the second was born in 1767 or 1768 in Frederick County, Virginia. He married, but his wife’s name is unknown. We do, however, know that her mitochondrial DNA haplogroup is H2a1. Without any other moniker, H2a1 has in effect become her name, because I have nothing else to call her that identifies her individually.

We don’t know much about H2a1, only that she was having children by about 1786 and had her last child, Catherine Crumley was born in 1805, suggesting that H2a1 herself was born about 1766.

It was Catherine Crumley’s descendant who took the mitochondrial DNA test that provided us with H2a1. Ironic that we have her mitochondrial DNA and know her haplogroup, but not her name. Of course, we are presuming that indeed, she was William II’s only wife, meaning that her haplogroup applied to her eldest child, Susannah Crumley born about 1786 and the other 8 children born between Susannah and Catherine.

H2a1’s son, William Crumley III was born between 1785 and 1789. William would have inherited his mother’s mitochondrial DNA, H2a1, but he would not have passed it on to his children. Mitochondrial DNA is only passed on by females. William’s children would have inherited their mitochondrial DNA from his wife, their mother.

William III married Lydia Brown on October 1, 1807 in Greene County, Tennessee, where the family had moved by 1793. Lydia was the daughter of Jotham Brown and his wife Phoebe, whose surname is unknown, neighbors who lived close by.

As couples do, William III and Lydia set about starting a family right away, having their first child, the Reverend John Crumley in 1808 or 1809. John was followed by William Crumley the fourth in 1811 and Jotham Crumley in 1813. Sarah may have been a twin to Jotham, born in 1813 or she may have been born in 1815. Of course, there were no birth or death certificates back then.

In 1817, daughter Clarissa was born on April 10th.

That’s where the confusion starts.

Enter Elizabeth Johnson

Enter Elizabeth, known as Betsey, Johnson who married William Crumley in Greene County, TN on October 20, 1817.

Which William Crumley, you ask? Well, so have we, for years. In fact, it’s discussed at length, here.

Given Elizabeth’s age of approximately 17 years when she married (assuming she is who we think she is,) and the fact she was remembered as the cousin of Lydia Brown, we presumed that she married William Crumley III. William III at approximately age 35-40 was closer to her age than William II at approximate age 55 – and Lydia Brown was the wife of William III so it stood to reason that they family would know her cousins.

Seems logical, right?

Except, the next child born to William III and his wife, Lydia or Elizabeth, my ancestor, Phoebe Crumley was born on March 24th, 1818, not even 50 weeks after her sister, Clarissa had been born. Furthermore, Phoebe had been born in Claiborne County, Tennessee, near the border with Lee County, Virginia, not in Greene County where earlier children were born. Also of note, Lydia’s mother, Jotham Brown’s wife was named Phoebe.

It’s certainly possible that William Crumley III’s first wife, Lydia Brown had died and he had remarried quickly to Elizabeth Johnson, then moved to Claiborne County. Except, the dates don’t work well.

We know that Lydia Brown Crumley was alive on April 10, 1817 when Clarissa was born.

Phoebe’s mother, whoever she was, got pregnant in June of 1817, 4 months before Elizabeth Johnson married William Crumley.

Pregnancy as a motivator for marriage happens, but it seemed odd that a 34 year old man with a 2 month old child, whose wife had just died was impregnating a 17 year old girl.

I discussed all the pros and cons of the situation in the articles about Lydia Brown and Phoebe Crumley, but the only other alternative is that Elizabeth Johnson had married the elder William Crumley II. It seems even odder that a man of 50+ would be marrying a girl of 17. But that too happened. Or, maybe Elizabeth was actually older than we thought.

Furthermore, William Crumley II had no additional children after 1817, at least none that we know of, but William III did. Yes, it looked quite probable that Elizabeth Johnson married William Crumley III. Young wives tended to have children, regardless of the age of their husband – so the preponderance of circumstantial evidence pointed to Elizabeth marrying William Crumley III, or Jr. as he was called in Greene County. William Crumley II was referred to as William Sr.

This seemed like the most reasonable (at least tentative) conclusion, based on the evidence at hand.

The problem is that it was wrong.

DNA Upsets the Apple Cart

One of my cousins who descends from Clarissa (born in April 1817) through all females kindly tested her mitochondrial DNA years ago. My line, through Phoebe, the younger sister of Clarissa had tested too, and they matched exactly at the full sequence level. Furthermore, both of those women also matched a descendant of a daughter of Jotham Brown, confirming that those three women had a common ancestor.

This tells us that very likely Clarissa and Phoebe are full siblings. However, dates weren’t always recorded correctly and people simply forgot. Were those two girls’ births recorded in the correct order with the correct years?

I really wanted to test a descendant of the daughter, Melinda, born April 1, 1820. That child was unquestionably born after the 1817 marriage to the second wife, if she was a second wife.

Not long ago, as a result of the article about Lydia, a descendant of Melinda came forth and volunteered to test.

Believe me, those weeks spent waiting for DNA results seemed like an eternity.

Finally, the results were ready, and sure enough, Melinda’s descendant matches Clarissa’s descendant and Phoebe’s descendant at the full sequence level, exactly.

The proof doesn’t get any better than this.

Except…

One Final Hitch

I’d feel a lot better if there wasn’t one last rumor to contend with. The rumor that Elizabeth Johnson was Lydia Brown’s cousin.

Elizabeth Johnson had to be either the daughter of Zopher Johnson, or the daughter of Moses Johnson, both of Greene County, TN. Moses was either the brother or the son of Zopher Johnson. Those are the only candidate fathers for Elizabeth.

Let’s look at the various possible relationships.

Possibility #1 – Jotham Brown’s wife, Phoebe, is Zopher Johnson’s Daughter as is Elizabeth Johnson

I already discussed the possibility that Jotham Brown’s wife, Phoebe, was Zopher Johnson’s daughter, here.

In the scenario above, Elizabeth and Lydia would not have been cousins, but aunt/niece. Their mitochondrial DNA would have matched, but in the article about Jotham Brown’s wife, Phoebe, we dismissed the possibility that she was Zopher Johnson’s daughter, so Possibility #1 isn’t possible after all.

Possibility #2 – Jotham Brown’s Wife, Phoebe, is the Daughter of Zopher Johnson and Elizabeth is Zopher’s Granddaughter Through Son Moses

In the above scenario, if Moses was the son of Zopher, these women would be first cousins, but the mitochondrial DNA lineage would be broken at Moses, so their mitochondrial DNA wouldn’t match.

Additionally, we dismissed the possibility that Phoebe is Zopher’s daughter, so Possibility #2 is not, for 2 different reasons. It’s possible that we’re wrong about Phoebe being Zopher’s daughter, but it’s NOT possible that we’re wrong about the mitochondrial DNA not matching in this scenario.

Furthermore Moses is believed to be the brother of Zopher, not his son.

Possibility #3 – Phoebe is Zopher’s Daughter, Moses is Zopher’s Brother and Elizabeth is Moses’s Daughter

The possibilities really aren’t endless, they just seem that way! 😊

In this third scenario where Moses and Zopher are brothers, not father and son, Elizabeth and Lydia would be 1st cousins once removed, but they would not share mitochondrial DNA unless Zopher and Moses had married sisters or women who also shared the same exact mitochondrial DNA.

The only scenario in which the mitochondrial DNA would be shared with cousins, assuming that Elizabeth Johnson and Lydia Brown were indeed cousins, is Possibility 1 where Jotham’s wife is Zopher’s daughter.

The evidence suggests that Phoebe Brown is not the daughter of Zopher Johnson, eliminating Possibility 3 as well.

Possibility #4 – Zopher Johnson’s Wife and Jotham Brown’s Wife Were Sisters

I’m going to presume here that the individual who recorded that Elizabeth Johnson and Lydia Brown were cousins meant first cousins, although it’s possible that cousin means further back and possibly not in the direct matrilineal line.

For Elizabeth Johnson’s mitochondrial DNA to match that of Lydia Brown’s exactly, they must both descend from the same common female ancestor in the direct matrilineal line.

How might that work, assuming Jotham’s wife is not Zopher’s daughter?

If the child of both Elizabeth Johnson and Lydia Brown had matching mitochondrial DNA, then the cousin lineage had to be through their mother’s matrilineal side.

This means that the wives of Zopher Johnson and Jotham Brown would have been sisters, or possible matrilineal cousins with no interweaving male generations.

Zopher Johnson and Jotham Brown were both found in Frederick Co., VA by 1782 where the tax list tells us that Zopher had 2 people in his household, indicating that he had not been married long.

Jotham Brown and Phebe, his wife are having children by 1761 in Virginia according to the 1850 census record of their oldest child.

These couples are probably at least 20 years different in age.

Unfortunately, we know very little about where Jotham originated. We know that Zopher’s parents were living in Northampton Co., PA in 1761 about the time he was born.

In order for Jotham’s wife, Phoebe to be the sibling of Zopher Johnson’s wife, they would have had to be living in the same location in roughly 1780, which was probably Frederick Co., VA.

Is it possible that the reason that Clarissa, Phoebe and Melinda’s mitochondrial DNA matches is because they actually do have two separate mothers who were cousins? Yes, it is.

Is there any evidence of that? No, not today.

However, this is the only alternate possibility that works at all.

Of course, the most reasonable scenario is that Lydia Brown didn’t die, and Clarissa, Phoebe and Melinda are all 3 her daughters. This evidence is strengthened of course by the fact that Phoebe is named after Lydia Brown’s mother.

What Other Tools are Available?

Unfortunately, Jotham Brown is 6 generations back from me. If Phoebe’s mother was Elizabeth Johnson instead of Lydia Brown, Zopher Johnson would be the same number of generations back in my tree as Jotham Brown.

The absence of Johnson autosomal matches in and of itself at that distance wouldn’t be remarkable for any particular individual, but with as many people from this line who have tested, it’s increasingly unlikely that I would match no one from the Johnson line.

At Ancestry, I added Zopher Johnson in my tree, as Jotham Brown’s wife, Phoebe’s father, creating a “honey-pot” of sorts for matches. I have no one that shares Zopher except for people who also have Phoebe listed as Phoebe Johnson. In other words, no one who descends from Zopher through any other line.

I have 27 people who I match through Jotham Brown through his other children, which I wouldn’t have as matches unless Jotham Brown was my ancestor as well.

At MyHeritage, I also added Zopher Johnson, but I have not had SmartMatches there either. Like at Ancestry, I do have Jotham Brown matches.

Several people match at Ancestry who has no chromosome browser. I have a Jotham Brown Circle at Ancestry with 45 members, of which I match 16.

Not all my matches are from Ancestry. Other matches are found at Family Tree DNA, MyHeritage and GedMatch which allow me to paint their segments on my DNAPainter profile, triangulating with others.

Conclusion

We have multiple pieces of evidence including three matching mitochondrial DNA tests for the sisters, children of William Crumley III, on the following timeline:

Crumley birth timeline

  • We’ve proven that Clarissa, Phebe and Melinda all share the exact same mitochondrial DNA. These births occurred both before and after the marriage of Elizabeth Johnson to one of the William Crumleys in 1817.
  • I have more than 30 matches to several of Jotham Brown’s descendants through multiple children other than through Lydia Brown, the wife of William Crumley III.
  • I don’t have any matches to Zopher Johnson through anyone except people who list Jotham Brown’s wife, Phebe, as the daughter of Zopher Johnson in their trees.
  • Jotham Brown’s wife’s name was Phebe, a rather unusual name, certainly suggesting that Lydia Brown was the mother of Phebe Crumley born in 1818.

I believe the combination of these factors confirms beyond any reasonable doubt that the mother of Phoebe Crumley born in 1818, as well as the younger children born to William Crumley III and his wife were all born to Lydia Brown, the first and only known wife of William Crumley III.

I believe that Elizabeth Johnson married William Crumley II, not William Crumley III based on this as well as new research evidence to be discussed in a future article.

Based on the cumulative evidence, Elizabeth Johnson did not marry William Crumley III and Lydia Brown, William Crumley III’s first wife did not die before the birth of either Phebe or Melinda Crumley.

Based on the fact that I have no autosomal DNA matches to Zopher Johnson’s descendants, I believe we’ve removed the possibility that Jotham Brown’s wife, Phebe is the daughter of Zopher, or the child of Zopher’s brother, Moses. In other words, there is no hint of a biological connection between the Johnson and Brown families upstream of Jotham Brown and his wife, Phoebe whose surname remains unknown.

As far as I’m concerned, we can put this question to bed, forever.

Whole Genome Sequencing – Is It Ready for Prime Time?

Dante Labs is offering a whole genomes test for $199 this week as an early Black Friday special.

Please note that just as I was getting ready to push the publish button on this article, Veritas Genetics also jumped on the whole sequencing bandwagon for $199 for the first 1000 testers Nov. 19 and 20th. In this article, I discuss the Dante Labs test. I have NOT reviewed Veritas, their test nor terms, so the same cautions discussed below apply to them and any other company offering whole genome sequencing. The Veritas link is here.

Update – Veritas provides the VCF file for an additional $99, but does not provide FASTQ or BAM files, per their Tweet to me.

I have no affiliation with either company.

$199 (US) is actually a great price for a whole genome test, but before you click and purchase, there are some things you need to know about whole genome sequencing (WGS) and what it can and can’t do for you. Or maybe better stated, what you’ll have to do with your own results before you can utilize the information for genealogical purposes.

The four questions you need to ask yourself are:

  • Why do you want to consider whole genome testing?
  • What question(s) are you trying to answer?
  • What information do you seek?
  • What is your testing goal?

I’m going to say this once now, and I’ll say it again at the end of the article.

Whole genome sequencing tests are NOT A REPLACEMENT FOR GENEALOGICAL DNA TESTS for mitochondrial, Y or autosomal testing. Whole genome sequencing is not a genealogy magic bullet.

There are both pros and cons of this type of purchase, as with most everything. Whole genome tests are for the most experienced and technically savvy genetic genealogists who understand both working with genetics and this field well, who have already taken the vendors’ genealogy tests and are already in the Y, mitochondrial and autosomal comparison data bases.

If that’s you or you’re interested in medical information, you might want to consider a whole genome test.

Let’s start with some basics.

What Is Whole Genome Sequencing?

Whole Genome Sequencing will sequence most of your genome. Keep in mind that humans are more than 99% identical, so the only portions that you’ll care about either medically or genealogically are the portions that differ or tend to mutate. Comparing regions where you match everyone else tells you exactly nothing at all.

Exome Sequencing – A Subset of Whole Genome

Exome sequencing, a subset of whole genome sequencing is utilized for medical testing. The Exome is the region identified as the portions most likely to mutate and that hold medically relevant information. You can read about the benefits and challenges of exome testing here.

I have had my Exome sequenced twice, once at Helix and once at Genos, now owned by NantOmics. Currently, NantOmics does not have a customer sign-in and has acquired my DNA sequence as part of the absorption of Genos. I’ll be writing about that separately. There is always some level of consumer risk in dealing with a startup.

I wrote about Helix here. Helix sequences your Exome (plus) so that you can order a variety of DNA based or personally themed products from their marketplace, although I’m not convinced about the utility of even the legitimacy of some of the available tests, such as the “Wine Explorer.”

On the other hand, the world-class The National Geographic Society’s Genographic Project now utilizes Helix for their testing, as does Spencer Well’s company, Insitome.

You can also pay to download your Exome sequence data separately for $499.

Autosomal Testing for Genealogy

Both whole genome and Exome testing are autosomal testing, meaning that they test chromosomes 1-22 (as opposed to Y and mitochondrial DNA) but the number of autosomal locations varies vastly between the various types of tests.

The locations selected by the genealogy testing companies are a subset of both the whole genome and the Exome. The different vendors that compare your DNA for genealogy generally utilize between 600,000 and 900,000 chip-specific locations that they have selected as being inclined to mutate – meaning that we can obtain genealogically relevant information from those mutations.

Some vendors (for example, 23andMe and Ancestry) also include some medical SNPs (single nucleotide polymorphisms) on their chips, as both have formed medical research alliances with various companies.

Whole genome and Exome sequencing includes these same locations, BUT, the whole genome providers don’t compare the files to other testers nor reduce the files to the locations useful for genealogical comparisons. In other words, they don’t create upload files for you.

The following chart is not to scale, but is meant to convey the concept that the Exome is a subset of the whole genome, and the autosomal vendors’ selected SNPs, although not the same between the companies, are all subsets of the Exome and full genome.

I have not had my whole genome sequenced because I have seen no purpose for doing so, outside of curiosity.

This is NOT to imply that you shouldn’t. However, here are some things to think about.

Whole Genome Sequencing Questions

Coverage – Medical grade coverage is considered to be 30X, meaning an average of 30 scans of every targeted location in your genome. Some will have more and some will have less. This means that your DNA is scanned thirty different times to minimize errors. If a read error happens once or twice, it’s unlikely that the same error will happen several more times. You can read about coverage here and here.

Here’s an example where the read length of Read 1 is 18, and the depth of the location shown in light blue is 4, meaning 4 actual reads were obtained. If the goal was 30X, then this result would be very poor. If the goal was 4X then this location is a high quality result for a 4X read.

In the above example, if the reference value, meaning the value at the light blue location for most people is T, then 4 instances of a T means you don’t have a mutation. On the other hand, if T is not the reference value, then 4 instances of T means that a mutation has occurred in that location.

Dante Labs coverage information is provided from their webpage as follows:

Other vendors coverage values will differ, but you should always know what you are purchasing.

Ownership – Who owns your data? What happens to your DNA itself (the sample) and results (the files) under normal circumstances and if the company is sold. Typically, the assets of the company, meaning your information, are included during any acquisition.

Does the company “share, lease or sell” your information as an additional revenue stream with other entities? If so, do they ask your permission each and every time? Do they perform internal medical research and then sell the results? What, if anything, is your DNA going to be used for other than the purpose for which you purchased the test? What control do you exercise over that usage?

Read the terms and conditions carefully for every vendor before purchasing.

File Delivery – Three types of files are generated during a whole genome test.

The VCF (Variant Call Format) which details your locations that are different from the reference file. A reference file is the “normal” value for humans.

A FASTQ file which includes the nucleotide sequence along with a corresponding quality score. Mutations in a messy area or that are not consistent may not be “real” and are considered false positives.

The BAM (Binary Alignment Map) file is used for Y DNA SNP alignment. The output from a BAM file is displayed in Family Tree DNA’s Big Y browser for their customers. Are these files delivered to you? If so, how? Family Tree DNA delivers their Big Y DNA BAM files as free downloads.

Typically whole genome data is too large for a download, so it is sent on a disc drive to you. Dante provides this disc for BAM and FASTQ files for 59 Euro ($69 US) plus shipping. VCF files are available free, but if you’re going to order this product, it would be a shame not to receive everything available.

Version – Discoveries are still being made to the human genome. If you thought we’re all done with that, we’re not. As new regions are mapped successfully, the addresses for the rest change, and a new genomic map is created. Think of this as street addresses and a new cluster of houses is now inserted between existing houses. All of the houses are periodically renumbered.

Today, typically results are delivered in either of two versions: hg19(GRVH37) or hg38(GRCH38). What happens when the next hg (human genome) version is released?

When you test with a vendor who uses your data for comparison as a part of a product they offer, they must realign your data so that the comparison will work for all of their customers (think Family Tree DNA and GedMatch, for example), but a vendor who only offers the testing service has no motivation to realign your output file for you. You only pay for sequencing, not for any after-the-fact services.

Platform – Multiple sequencing platforms are available, and not all platforms are entirely compatible with other competing platforms. For example, the Illumina platform and chips may or may not be compatible with the Affymetrix platform (now Thermo Fisher) and chips. Ask about chip compatibility if you have a specific usage in mind before you purchase.

Location – Where is your DNA actually being sequenced? Are you comfortable having your DNA sent to that geographic location for processing? I’m personally fine with anyplace in either the US, Canada or most of Europe, but other locations maybe not so much. I’d have to evaluate the privacy policies, applicable laws, non-citizen recourse and track record of those countries.

Last but perhaps most important, what do you want to DO with this file/information?

Utilization

What you receive from whole genome sequencing is files. What are you going to do with those files? How can you use them? What is your purpose or goal? How technically skilled are you, and how well do you understand what needs to be done to utilize those files?

A Specific Medical Question

If you have a particular question about a specific medical location, Dante allows you to ask the question as soon as you purchase, but you must know what question to ask as they note below.

You can click on their link to view their report on genetic diseases, but keep in mind, this is the disease you specifically ask about. You will very likely NOT be able to interpret this report without a genetic counselor or physician specializing in this field.

Take a look at both sample reports, here.

Health and Wellness in General

The Dante Labs Health and Wellness Report appears to be a collaborative effort with Sequencing.com and also appears to be included in the purchase price.

I uploaded both my Exome and my autosomal DNA results from the various testing companies (23andMe V3 and V4, Ancestry V1 and V2, Family Tree DNA, LivingDNA, DNA.Land) to Promethease for evaluation and there was very little difference between the health-related information returned based on my Exome data and the autosomal testing vendors. The difference is, of course, that the Exome coverage is much deeper (and therefore more reliable) because that test is a medical test, not a consumer genealogy test and more locations are covered. Whole genome testing would be more complete.

I wrote about Promethease here and here. Promethease does accept VCF files from various vendors who provide whole genome testing.

None of these tests are designed or meant for medical interpretation by non-professionals.

Medical Testing

If you plan to test with the idea that should your physician need a genetics test, you’re already ahead of the curve, don’t be so sure. It’s likely that your physician will want a genetics test using the latest technology, from their own lab, where they understand the quality measures in place as well as how the data is presented to them. They are unlikely to accept a test from any other source. I know, because I’ve already had this experience.

Genealogical Comparisons

The power of DNA testing for genealogy is comparing your data to others. Testing in isolation is not useful.

Mitochondrial DNA – I can’t tell for sure based on the sample reports, but it appears that you receive your full sequence haplogroup and probably your mutations as well from Dante. They don’t say which version of mitochondrial DNA they utilize.

However, without the ability to compare to other testers in a database, what genealogical benefit can you derive from this information?

Furthermore, mitochondrial DNA also has “versions,” and converting from an older to a newer version is anything but trivial. Haplogroups are renamed and branches sawed from one part of the mitochondrial haplotree and grafted onto another. A testing (only) vendor that does not provide comparisons has absolutely no reason to update your results and can’t be expected to do so. V17 is the current build, released in February 2016, with the earlier version history here.

Family Tree DNA is the only vendor who tests your full sequence mitochondrial DNA, compares it to other testers and updates your results when a new version is released. You can read more about this process, here and how to work with mtDNA results here.

Y DNA – Dante Labs provides BAM files, but other whole genome sequencers may not. Check before you purchase if you are interested in Y DNA. Again, you’ll need to be able to analyze the results and submit them for comparison. If you are not capable of doing that, you’ll need to pay a third party like either YFull or FGS (Full Genome Sequencing) or take the Big Y test at Family Tree DNA who has the largest Y Database worldwide and compares results.

Typically whole genome testers are looking for Y DNA SNPs, not STR values in BAM files. STR (short tandem repeat) values are the results that you receive when you purchase the 37, 67 or 111 tests at Family Tree DNA, as compared to the Big Y test which provides you with SNPs in order to resolve your haplogroup at the most granular level possible. You can read about the difference between SNPs and STRs here.

As with SNP data, you’ll need outside assistance to extract your STR information from the whole genome sequence information, none of which will be able to be compared with the testers in the Family Tree DNA data base. There is also an issue of copy-count standardization between vendors.

You can read about how to work with STR results and matches here and Big Y results here.

Autosomal DNA – None of the major providers that accept transfers (MyHeritage, Family Tree DNA, GedMatch) accept whole genome files. You would need to find a methodology of reducing the files from the whole genome to the autosomal SNPs accepted by the various vendors. If the vendors adopt the digital signature technology recently proposed in this paper by Yaniv Erlich et al to prevent “spoofed files,” modified files won’t be accepted by vendors.

Summary

Whole genome testing, in general, will and won’t provide you with the following:

Desired Feature Whole Genome Testing
Mitochondrial DNA Presumed full haplogroup and mutations provided, but no ability for comparison to other testers. Upload to Family Tree DNA, the only vendor doing comparisons not available.
Y DNA Presume Y chromosome mostly covered, but limited ability for comparison to other testers for either SNPs or STRs. Must utilize either YFull or FGS for SNP/STR analysis. Upload to Family Tree DNA, the vendor with the largest data base not available when testing elsewhere.
Autosomal DNA for genealogy Presume all SNPs covered, but file output needs to be reduced to SNPs offered/processed by vendors accepting transfers (Family Tree DNA, MyHeritage, GedMatch) and converted to their file formats. Modified files may not be accepted in the future.
Medical (consumer interest) Accuracy is a factor of targeted coverage rate and depth of actual reads. Whole genome vendors may or may not provide any analysis or reports. Dante does but for limited number of conditions. Promethease accepts VCF files from vendors and provides more.
Medical (physician accepted) Physician is likely to order a medical genetics test through their own institution. Physicians may not be willing to risk a misdiagnosis due to a factor outside of their control such as an incompatible human genome version.
Files VCF, FASTQ and BAM may or may not be included with results, and may or may not be free.
Coverage Coverage and depth may or may not be adequate. Multiple extractions (from multiple samples) may or may not be included with the initial purchase (if needed) or may be limited. Ask.
Updates Vendors who offer sequencing as a part of a products that include comparison to other testers will update your results version to the current reference version, such as hg38 and mitochondrial V17. Others do not, nor can they be expected to provide that service.
Version Inquire as to the human genome (hg) version or versions available to you, and which version(s) are acceptable to the third party vendors you wish to utilize. When the next version of the human genome is released, your file will no longer be compatible because WGS vendors are offering sequencing only, not results comparisons to databases for genealogy.
Ownership/Usage Who owns your sample? What will it be utilized for, other than the service you ordered, by whom and for what purposes? Will you we able to authorize or decline each usage?
Location Where geographically is your DNA actually being sequenced and stored? What happens to your actual DNA sample itself and the resulting files? This may not be the location where you return your swab kit.

The Question – Will I Order?

The bottom line is that if you are a genealogist, seeking genetic information for genealogical purposes, you’re much better off to test with the standard and well know genealogy vendors who offer compatibility and comparisons to other testers.

If you are a pioneer in this field, have the technical ability required to make use of a whole genome test and are willing to push the envelope, then perhaps whole genome sequencing is for you.

I am considering ordering the Dante Labs whole genome test out of simple curiosity and to upload to Promethease to determine if the whole genome test provides me with something potentially medically relevant (positive or negative) that autosomal and Exome testing did not.

I’m truly undecided. Somehow, I’m having trouble parting with the $199 plus $69 (hard drive delivery by request when ordering) plus shipping for this limited functionality. If I was a novice genetic genealogist or was not a technology expert, I would definitely NOT order this test for the reasons mentioned above.

A whole genome test is not in any way a genealogical replacement for a full sequence mitochondrial test, a Y STR test, a Y SNP test or an autosomal test along with respective comparison(s) in the data bases of vendors who don’t allow uploads for these various functions.

The simple fact that 30X whole genome testing is available for $199 plus $69 plus shipping is amazing, given that 15 years ago that same test cost 2.7 billion dollars. However, it’s still not the magic bullet for genealogy – at least, not yet.

Today, the necessary integration simply doesn’t exist. You pay the genealogy vendors not just for the basic sequencing, but for the additional matching and maintenance of their data bases, not to mention the upgrading of your sequence as needed over time.

If I had to choose between spending the money for the WGS test or taking the genealogy tests, hands down, I’d take the genealogy tests because of the comparisons available. Comparison and collaboration is absolutely crucial for genealogy. A raw data file buys me nothing genealogically.

If I had not previously taken an Exome test, I would order this test in order to obtain the free Dante Health and Wellness Report which provides limited reporting and to upload my raw data file to Promethease. The price is certainly right.

However, keep in mind that once you view health information, you cannot un-see it, so be sure you do really want to know.

What do you plan to do? Are you going to order a whole genome test?
