FamilyTreeDNA Provides Y DNA Haplogroups from Family Finder Autosomal Tests

Posted on November 30, 2023 by Roberta Estes

Big News! FamilyTreeDNA is delivering holiday gifts early!

Y DNA haplogroups are beginning to be delivered as a free benefit to men who took the Family Finder test at FamilyTreeDNA. This is the first wave of a staggered rollout. Haplogroup results will be delivered to several thousand people at a time, in batches, beginning today.

This is no trivial gift and includes LOTS of information that can be used in various ways for your genealogy. Please feel free to share this article. The new Family Finder haplogroups are another reason to take a Family Finder test and to encourage other family members to do so as well.

How is this Even Possible?

Clearly, Y DNA is not autosomal DNA, so how is it possible to obtain a Y DNA or mitochondrial DNA haplogroup from an autosomal test? Great question!

Many autosomal DNA processing chips include a limited number of targeted Y and mitochondrial DNA SNP locations. Generally, those locations are haplogroup predictive, which is how haplogroup information can be obtained from an autosomal DNA test.

Compared to the actual Y DNA and mitochondrial DNA tests, only a small fraction of the information is available through autosomal tests. Only the full sequence mitochondrial DNA test or the Big Y-700 test will provide you with the full story, including your most refined haplogroup, additional information, and matching with other customers.

Having said that, haplogroups obtained from Family Finder provide important clues and genealogical information that will hopefully whet recipients’ appetites for learning even more.

Delivery Schedule

This first group of men to receive haplogroup results consists of testers who have purchased the Family Finder test since March 2019 when the most recent chip was put into production.

FamilyTreeDNA will be rolling haplogroups out in batches of a few thousand each day until everyone’s is complete, in the following order:

Family Finder tests purchased since March 2019 (their V3 chip)
Family Finder tests purchased between the fall of 2015 to March 2019 (their V2 chip)
Family Finder tests purchased from 2010 to the fall of 2015 (their V1 chip)
Autosomal uploads from other vendors for customers who have unlocked the advanced Family Finder features for $19

Uploaded DNA Files from Other Vendors

After the results are available for all males who have tested at FamilyTreeDNA, haplogroups will begin to be rolled out to customers who uploaded autosomal DNA files from other companies, meaning MyHeritage, Vitagene, 23andMe, and Ancestry.

To receive haplogroups for files uploaded from other vendors, the Family Finder advanced tool unlock must have been (or can be) purchased for $19. In addition to haplogroups, the unlock also provides access to the chromosome browser, myOrigins (ethnicity), Chromosome painting for myOrigins ethnicity, and ancient Origins.

Both MyHeritage and Vitagene tests are performed in the Gene by Gene lab. Those “uploads” are actually a secure business-to-business transaction, so the file integrity is assured.

Ancestry and 23andMe DNA files are downloaded from those companies, then uploaded to FamilyTreeDNA. Some people build “composite” files in the format of these companies, so FamilyTreeDNA has no way to assure that the original DNA upload file hasn’t been modified and it is a legitimate, unmodified, file from either 23andMe or Ancestry. Hence, in some situations, they are treated differently.

Both Ancestry and 23andMe utilize different chips than FamilyTreeDNA, covering different SNPs. Those results may vary slightly from results available from native FamilyTreeDNA tests, and will also vary from each other. In other words, there’s no consistency, and therefore haplogroup accuracy cannot be confirmed.

Haplogroups resulting from tests performed in the FamilyTreeDNA lab will be visible to matches and on the SNP pages within projects. They will also be used in both Discover and the haplotree statistics. This includes Family Finder plus MyHeritage and Vitagene DNA file uploads.

Tests performed elsewhere will receive haplogroups that will only be visible to the user, or a group administrator viewing a kit within a project. They will not be visible to matches, used in trees or for statistics.

At their recent conference, FamilyTreeDNA provided this slide during an update about what to expect from Family Finder haplogroups.

Today, only Y DNA haplogroups are being provided, but after the new mitochondrial tree is available, customer haplogroups are updated, and MitoDiscover (my name, not theirs) is released, FamilyTreeDNA is planning to provide mitochondrial DNA haplogroups for Family Finder customers as well. The current haplogroup estimate is late 2024 or even into 2025.

Unfortunately, some of Ancestry’s DNA files don’t include mitochondrial DNA SNPs, so some customers who’ve uploaded Ancestry files won’t receive mitochondrial haplogroups.

STR Haplogroups to be Updated

All FamilyTreeDNA customers who have taken Y DNA STR tests, meaning 12, 25, 37, 67, or 111 markers, receive predicted haplogroups. Often, the Family Finder extracted results can provide a more refined haplogroup.

When that is possible, STR test predicted haplogroup results will be updated to the more refined Family Finder haplogroup.

Furthermore, while STR results are quite reliably predicted, Family Finder results are SNP-confirmed.

Notification

When your Family Finder test has received a haplogroup or your STR-derived haplogroup has been updated, you’ll receive an email notification with a link to a short, less than 2-minute video explaining what you’re receiving.

You can also expect emails in the following days with links to additional short videos. If you’d like to watch the videos now, click here.

You can also check your results, of course. If you should have received an email and didn’t, check your spam folder, and if it’s not there, notify FamilyTreeDNA in case your email has managed to get on the bounce list.

Group project administrators will receive notifications when a haplogroup is updated for a member in a project that they manage. This doesn’t just apply to Family Finder haplogroup updates for STR results – notifications will arrive when Big Y haplogroups are updated, too.

Emails about haplogroup updates will include both the old and the updated haplogroup.

Haplogroups may change as other testers receive results, forming a new haplogroup. The Big Y-700 test is evergreen, meaning as the Y tree grows, testers’ results are updated on an ongoing basis.

New View

Let’s take a look at what customers will receive.

In one of my surname projects, one male has taken a Family Finder test, but not the Y DNA test.

Several other men in that same paternal line, who are clearly related (including his brother), have taken Y DNA tests – both STR and the Big Y-700.

We have men who have taken the Big Y-700 test, STR tests only (no Big Y), and one with only a Family Finder test, so let’s compare all three, beginning with the man who has taken a Family Finder test but no Y DNA tests.

He has now been assigned to haplogroup I-BY1031, thanks to his Family Finder test.

Before today, because he has not taken a Y DNA test, he had no haplogroup or Y DNA Results section on his personal page.

Today, he does. Of course, he doesn’t have STR results or matches, but he DOES have confirmed SNP results, at least part way down the tree.

He can view these results on the Haplotree & SNPs tab or in Discover. Let’s look at both.

Haplotree & SNPs

By clicking on the Haplotree & SNPs link, you can view the results by variants (mutations,) as shown below, or by countries, surnames, or recommended projects for each haplogroup.

Of course, as more Family Finder results are rolled out, the more names and countries will appear on the Haplotree.

Recommended Projects

It’s easy to determine which haplogroup projects would be a good fit for people with these new haplogroups to join.

Just view by Recommended Projects, then scan up that column above the selected haplogroup. You can even just click right there to join. It’s that easy!

Results still won’t show on the public project page, because these testers don’t have STR results to display. Perhaps this will encourage additional testing in order to match with other men.

Download SNP Results

If you’re interested, you can download your SNP results in spreadsheet format.

I’m only showing four of my cousin’s positive SNPs, but FamilyTreeDNA was able to extract 358 positive SNPs to assign him to haplogroup I-BY1031.

Are Family Finder Haplogroups Better Than STR Test Predicted Haplogroups?

How do Family Finder haplogroups stack up against STR-predicted haplogroups?

Viewing the Y DNA results of related cousins who have taken STR tests, but not the Big Y-700, we see that their Y DNA haplogroup was predicted as I-M253.

We also know that the haplogroup determined by the Big Y-700 for this line is I-BY73911.

How can we use this information beneficially, and what does it mean?

Discover

Family Finder haplogroups can access Discover, which I wrote about, here.

Clicking on the Discover link takes you to your haplogroup story.

Let’s look at the new Family Finder Haplogroup Story for this tester.

Haplogroup I-BY1031 is about 3100 years old and is found in England, Sweden, the US, and 14 other countries. Of course, as more Family Finder haplogroups are provided to customers, this information will change for many haplogroups, so check back often.

Of course, you’ll want to review every single tab, which are chapters in your ancestral story! The Time Tree shows your haplogroup age in perspective to other haplogroups and their formation, and Ancient Connections anchors haplogroups through archaeology.

You can share any Discover page in several ways. This is a good opportunity to excite other family members about the discoveries revealed through DNA testing and genealogy. Prices are reduced right now with the Holiday Sale, too, so it’s a great time to gift someone else or yourself.

Compare – How Good is Good?

Ok, so how much better is the Family Finder haplogroup than the STR-predicted haplogroup, and how much better is the Big Y-700 haplogroup than the other two?

I’ll use the Discover “Compare” feature to answer these questions.

First, let’s compare the STR-predicted haplogroup of I-M253 to the Family Finder haplogroup of I-BY1031.

I clicked on Compare and entered the haplogroup I wish to compare to I-BY1031.

	I-M253	I-BY1031	I-BY73199
Haplogroup Source	STR Predicted	Family Finder	Big Y-700
Formation Year	2600 BCE	1100 BCE	1750 CE
Age – Years ago	4600	3100	270
Era	Stone Age, Metal Age	Metal Age	Modern
Ancestral Locations	England, Sweden, Germany, UK, +100	Sweden, England, US, +14	Netherlands
Tested Descendants	26,572	121	2
Branches	6779	69	0 – this is the pot-of-gold end leaf on the branch today

I created this chart to compare the major features of all three haplogroups.

The STR-predicted haplogroup, I-M253, takes you to about 2,600 BCE, or about 4,600 years ago. The Family Finder haplogroup shifts that significantly to about 1100 BCE, or 3100 years ago, so it’s about 1500 years more recent. However, the Big Y haplogroup takes you home – from 3100 years ago to about 270 years ago.

Notice that there’s a LOT of room for refinement under haplogroup I-M253. A Big Y tester might wind up on any of those 6779 branches, and might well be assigned to a newly formed branch with his test. The Family Finder haplogroup, I-BY1031, which was, by the way, discovered through Big Y testing, moved the autosomal test taker forward 1500 years where there are 121 descendants in 69 branches. The Big Y-700 test is the most refined possible, moving you directly into a genealogically relevant timeframe with a very specific location.

I-M253 is found in over 100 countries, I-BY1031 in 17 and I-BY73199 is found only in one – the Netherlands.

Based on confirmed genealogy, the common ancestor of the two men who have Big Y-700 haplogroup I-BY73199 was a man named Hendrik Jans Ferwerda, born in 1806 in the Netherlands, so 217 years ago. Of course, that haplogroup itself could have been born a generation or two before Hendrik. We simply won’t know for sure until more men test. More testers refine the haplotree, haplogroup ages, and refine our genealogy as well.

Haplogroup Comparison and Analysis

Let’s look at the Discover “Compare” feature of the three haplogroups from my family line from the Netherlands. Please note that your results will differ because every haplogroup is different, but this is a good way to compare the three types of haplogroup results and an excellent avenue to illustrate why testing and upgrades are so important.

The haplogroup ages are according to the Discover Time Tree.

Y-Adam to Haplogroup I1	I-M253 STR Haplogroup to I-BY1031 Family Finder Haplogroup	I-BY1031 Family Finder Haplogroup to BY73199 Big Y Haplogroup

		FT230048
		BY65928
		BY61100
		I-BY73199 lived about 270 years ago

All of the base haplogroups in the first column leading to Haplogroup I span the longest elapsed time, about 230,000 years, from Y-Adam to I-M253, the STR-predicted haplogroup, but are the least relevant to contemporary genealogy. They do tell us where we came from more distantly.

The second column moves you about 1500 years forward in time to the Family Finder confirmed haplogroup, reducing the location from pretty much everyplace in Europe (plus a few more locations) with more than 6700 branches, to 69 branches in only 17 countries.

With the fewest haplogroups, the third column spans the most recent 2800 years, bringing you unquestionably into the genealogically relevant timeframe, 270 years ago, in only one country where surnames apply.

If we had more testers from the Netherlands or nearby regions, there would probably be more branches on the tree between BY1031 and BY73199, the Big Y-700 haplogroup.

The second column is clearly an improvement over the first column which gets us to I-M253. The Family Finder upgrade from I-M253 to BY1031 provides information about our ancestors 3000-4500 years ago, where they lived and culturally, what they were doing. Ancient Connections enhance that understanding.

But the third column moves into the modern area where surnames are relevant and is the holy grail of genealogy. It’s a journey to get from Adam to the Netherlands in one family 270 years ago, but we can do it successfully between Family Finder and the Big Y-700.

Family Finder Matching

Given that these new haplogroups result from Family Finder, how do these results show in Family Finder matching? How do we know if someone with a haplogroup has taken a Y DNA test or if their haplogroup is from their Family Finder test?

All Family Finder haplogroups will show in the results for people who tested at FamilyTreeDNA as soon as they are all rolled out
All MyHeritage and Vitagene uploads, because they are processed by the Gene by Gene lab, will be shown IF they have purchased the unlock.
No Ancestry or 23andMe haplogroups will be shown to Family Finder matches

To determine whether or not your matches’ haplogroups result from a Y DNA test or a Family Finder haplogroup, on your Family Finder match page, look just beneath the name of your matches.

The first man above received the Family Finder haplogroup. You can see he has no other tests listed. The second man has taken the Big Y-700 test. You can see that he has a different haplogroup, and if you look beneath his name, you’ll see that he took the Big Y-700 test.

For other men, you may see the 67 or 111 marker tests, for example, so you’ll know that they are available for Y-DNA matching. That may be important information because you can then visit the appropriate surname project to see if they happen to be listed with an earliest known ancestor.

After the rollout is complete, If you have a male Family Finder match with no haplogroup shown, you know that:

They did not test at FamilyTree DNA
If they uploaded from MyHeritage or Vitagene, they did not unlock the advanced Family Finder features
Or, they tested at either 23andMe or Ancestry, and uploaded their results

You can always reach out to your match and ask.

How to Use This Information

There are several great ways to utilize this new information.

First, Family Finder haplogroups are a HUGE timesaver.

I have a roadblock with my Moore line. Moore is a common surname with many, many origins, so I have autosomal matches to several Moore individuals who may or may not be from my Moore line.

I do know the base haplogroup of my Moore men, but I do not have a Big Y, unfortunately, and can’t upgrade because the tester is deceased. (I wish I had ordered the Big Y out the gate, but too late now.)

As soon as the results are complete for all of the testers, I’ll be able, by process of elimination to some extent, focus ONLY on the testers who fall into Family Finder haplogroup of my Moore cousins, or at least haplogroup close for Ancestry or 23andMe upload customers. In other words, I can eliminate the rest.

I can then ask the men with a similar haplogroup to my proven Moore cousins for more information, including whether they would be willing to take a Y DNA test.

Second, as soon as the Family Finder processing is complete, I will know that all male Family Finder matches and uploads from MyHeritage and Vitagene that have paid for the unlock will have haplogroups displayed on the Family Finder Match page. Therefore, if there’s a male Moore with no haplogroup, I can reach out to see where they tested and if a haplogroup has been assigned, even if it’s from Ancestry or 23andMe and isn’t displayed in Family Finder.

If so, and they share the haplogroup with me, I’ll be able to include or exclude them. If included, I can then ask if they would consider taking a Y DNA test.

Third, for lines I don’t yet have Y DNA testers for, I can now peruse my matches, and my cousins’ matches for that line. See items one and two, above. Even if they don’t reply or agree to Y DNA testing, at least now I have SOME haplogroup for that missing line.

Discover will help me flesh out the information I have, narrow regions, find projects, look at ancient DNA for hints, and more.

Fourth, the haplogroups themselves. I don’t know how many million tests FamilyTreeDNA has in their database, but if we assume that half of those are male, some percentage won’t have taken a Y DNA test at all. We’ll be able to obtain Y-DNA information for lines where there may be no other living descendant. I have at least one like that. He was the end of the surname line and is deceased, with no sons.

I’m literally ecstatic that I’ll be able to obtain at least something for that line. If it’s anything like my example Netherlands lineage, the Family Finder haplogroup may be able to point me to an important region of Europe – or maybe someplace else very unexpected.

The Bottom Line

Here’s the bottom line. You don’t know what you don’t know – and our ancestors are FULL of surprises.

I can’t even begin to tell you how MUCH I’m looking forward to this haplogroup rollout.

To prepare, I’m making a list of my genealogical lines:

If the paternal line, meaning surname line, is represented by any match in any database
If that line is represented by a known person in the FamilyTreeDNA database and by whom
If they or someone from that line has joined a surname or other FamilyTreeDNA project, and if so, which one
If they’ve taken a Y DNA test, and what kind – watch STR results for an updated haplogroup
If they’ve taken a Family Finder test – my cousin is a good example of a known individual whose kit I can watch for a new haplogroup
Old and new haplogroup, if applicable

If my only relative from that line is in another vendor’s database, I’ll ask if they will upload their file to FamilyTreeDNA – and explain why by sharing this article. (Feel free to do the same.) A Y DNA haplogroup is a good incentive, and I would be glad to pay for the unlock at FamilyTreeDNA for cousins who represent Y and mitochondrial DNA lines I don’t already have.

One way I sweeten the pie is to offer testing scholarships to select lines where I need either the Y DNA or mitochondrial DNA of relevant ancestors. It’s a good thing these haplogroups are being rolled out a few thousand at a time! I need to budget for all the scholarships I’ll want to offer.

I feel like I won the lottery, and FamilyTreeDNA is giving me a free haplogroup encyclopedia of information about my ancestors through my cousins – even those who haven’t taken Y DNA tests. I can’t even express how happy this makes me.

What lines do you want to discover more about, and what is your plan? Tests are on sale now if you need them!

Ancestry Updates Ethnicity, Introduces New Features & Pushes Some Behind Paywall

Posted on September 27, 2023 by Roberta Estes

I knew something had changed at Ancestry when I signed in a few days ago and saw the following message:

Ancestry assured me that I’m fine, but people who don’t have a subscription can no longer see some DNA features.

Ancestry has placed some previously free features behind a paywall – meaning a subscription called AncestryDNA Plus.

If you have a full subscription to Ancestry, you’re covered. You’re not if you don’t have a full subscription and only ordered a DNA test.

I was waiting for clarification from Ancestry, which arrived in an email yesterday.

Ancestry’s Clarification

In the email from Ancestry, they listed the new AncestryDNA premium features, some of which were previously purchased separately, like Traits, some of which were included with the AncestryDNA test, and some of which are or will be new.

There are several features and changes, so let’s take a look.

AncestryDNA Plus Subscription

The biggest change is that Ancestry will now be requiring some type of membership, either a full Ancestry membership or an AncestryDNA Plus membership, in order to access several DNA features.

Ancestry has placed these features behind a paywall for customers without a full Ancestry subscription.

The subscription price is $29.99 for six months, not a year, and the subscription automatically renews. This means that unless you have a full Ancestry subscription, access to several DNA features now costs you $59.98 per year in addition to the price of your original DNA test. Ouch.

Whooboy. I can hear the screaming from here.

Yes, I know this is NOT what we were expecting when we purchased DNA tests, and I realize it’s quite pricey – especially given that it’s not a one-time purchase but an ongoing subscription.

I will review each of these features – but let me say that if you’ve been doing fine without them so far for your genealogy, there’s probably not anything you really need here.

The most important feature that genealogists need that is NOT available without a full Ancestry subscription is full access to the trees of our matches – and, to be clear, that is NOT available through the AncestryDNA Plus subscription.

Let’s look at each feature separately.

Traits and Traits by Parent

You know all those questions Ancestry has been asking you? Well, this is why.

Ancestry is comparing the DNA of individuals with specific answers to identify genetic commonalities.

Traits was a separate uplift fee in the past, but now it’s included in the AncestryDNA Plus subscription.

You may not have Traits on your account yet. My second test, which is a newer test, does NOT have traits available, but I’m sure it will soon.

If you have Traits, you will have a banner above your DNA Story, Matches and ThruLines on your DNA Results Summary page.

Ancestry includes 42 traits today.

Ancestry shows you which traits are most influenced by which parent, or both parents.

Where you fall within that range is provided as well.

Clicking on each trait provides additional information.

Don’t get too excited about this feature because some of these traits are apparently a lot more environmental than genetic. For example, according to Ancestry, male hair loss is “at least 4% genetic.” Each trait has similar information provided, and some have a surprisingly small percentage of genetic affinity. Others have a surprisingly large number of influencing genes.

Here’s a chart of my traits and the parent that Ancestry has assigned as most likely to have influenced this trait. Please note that for Ancestry to split your Traits by parent, you MUST be able to identify which side of your family your ethnicity categories descend from using SideView, which I wrote about, here. If your parents aren’t identified correctly, the source of your traits certainly won’t be either.

Trait & % Genetic	My Result	Influenced by	Trait Accuracy
Alcohol Flush – 4%	Face does not flush	Maternal	Wrong
Asparagus odor – 4%	Able to smell asparagus metabolites (in urine)	Paternal	Accurate
Birth weight – 5%	Above average	Both	Unknown
Bitter sensitivity – 20%	Unable to taste a certain bitter flavor (PTC in brussel sprouts)	Both	Accurate – I taste brussel sprouts, but they don’t taste bitter
Caffeine intake – 4%	Likely to drink a lot less caffeine than average	Paternal	Wrong – I can’t drink caffeinated beverages anymore, but when I could, I consumed coffee by the pot
Cilantro aversion – 5%	Unlikely to enjoy cilantro	Maternal	Accurate
Cleft Chin – 8%	No cleft chin	Paternal	Accurate
Dancing – 7%	Least likely to enjoy dancing	Maternal	This is hilarious – my mother was a professional dancer, and I love dancing
Earlobes – 9%	Unattached earlobes	Maternal	Accurate
Earwax type – 2%	Wet earwax	Both	Accurate
Eye color – 7%	Brown	Maternal	Accurate – although both parents had brown eyes
Facial hair fullness – 7%	Patchier facial hair	Maternal	No idea
Finger length – 5%	Ring finger longer than index finger	Maternal	Wrong
Freckles – 9%	Unlikely	Maternal	Accurate
Hair color – 25%	Dark hair	Paternal	Accurate, although both parents had dark hair
Hair strand thickness – 1%	Thin hair	Maternal	Wrong – hair very thick
Hair type – 1%	Wavy	Maternal	Accurate
Heart rate recovery – 12%	Quicker recovery rate after exercise	Both	No idea
Introvert or extrovert – 1%	Introvert	Maternal	Also hilarious – my mother was very much the extrovert
Iris patterns – 35%	Furrows, crypts, and rings	Both	Can’t tell
Male hair loss – 4%	Lower chance	Paternal	Probably accurate – my father was not balding in his 60s
Morning or night person – 17%	Morning	Paternal	Wrong, wrong, 1000 times wrong
Omega 3 – 4%	Average levels	Both	No idea
Oxygen use – 38%	Average ability to raise maximum oxygen use	Paternal	No idea
Picky eater – 8%	Picky	Maternal	Wrong
Remembering dreams – 1%	Unlikely	Paternal	I remember some, sometimes, but they tend to fade
Risk Taking – 9%	More likely than 60% of the population	Both	Probably accurate
Skin pigmentation – 13%	Light to medium	Both	Accurate
Sun sneezing – 8%	Non sneezer	Paternal	Accurate
Sweet sensitivity – 4%	Extra sensitive	Both	Accurate
Taking naps – 6%	Not a nap taker	Maternal	Accurate
Tolerating dairy – 1%	Likely to tolerate	Paternal	Accurate
Umami sensitivity – 1%	Less sensitive than others	Both	Uncertain – I can taste Umami but since this is comparative, I don’t really know
Unibrow – 1%	No unibrow	Paternal	Accurate
Vitamin A – 7%	Average level	Maternal	No idea
Vitamin B12 – 5%	Average level	Maternal	No idea
Vitamin C – 4%	Average level	Paternal	No idea
Vitamin D – 10%	Average level	Both	No idea
Vitamin E – 14%	Average level	Maternal	No idea
Wisdom Teeth – 8%	Likely to develop all four teeth	Maternal	Accurate

If you’re thinking to yourself – how can some of these traits be anything BUT genetic, such as unibrow, you’re not alone. How can unibrow and some other traits be anything BUT genetic?

Initially, I thought maybe this would help me learn about my father, who died when I was young, but based on the low percentage of genetic influence, combined with answers that I know are inaccurate – I can’t really rely on any of this genealogically either. All I can say is that I’m really glad I didn’t pay for this feature.

Ancestry writes about their trait predictions in a white paper, here.

At the bottom of the Traits page is a “Compare Traits” tab where you can invite your matches to share traits with you.

My own second kit is not on the list of people to invite, so maybe immediate family is not available to invite? Or maybe it’s because that kit doesn’t have traits yet.

Ethnicity Inheritance

Ethnicity Inheritance shows which of your ethnicities were inherited from each parent. This was previously included in the price of your DNA test, but now it’s available through either the full Ancestry subscription or through the AncestryDNA Plus subscription.

I wrote about ethnicity inheritance when SideView was introduced, here.

Matches are now split by parent.

These matches and totals have recently been updated, at the same time as ThruLines.

Significant issues have been reported with both features, with matches incorrectly assigned that were previously assigned correctly. ThruLines has improved somewhat, but still has not been corrected entirely. Many known cousins who were previously linked to our common ancestor in ThruLines are no longer linked. I wrote about the ThruLines issue, here.

Chromosome Painter

Ancestry’s chromosome painter is NOT a chromosome browser. Yes, it looks similar, but it definitely IS NOT the same thing.

What’s the difference between a chromosome browser and chromosome painting?

Chromosome browsing with matches and chromosome painting look similar, but they aren’t the same and have different functions.

A chromosome browser allows you to compare your matching DNA segments with others and view them in a browser to see which shared DNA segments overlap, indicating a common ancestor. A chromosome browser is required to perform triangulation, which confirms common ancestors and facilitates identifying which segments descend from specific ancestors. I provided a list of triangulation resources, here.

For example, three maternal cousins above are compared on my chromosomes (in grey) using the chromosome browser at FamilyTreeDNA. The three bars under chromosome 1 represent my matches with three selected cousins who descend from Hiram Ferverda and Eva Miller.

The first blue cousin matches me in two locations on chromosome 1.
The second red cousin matches me in two locations on chromosome 1, one of which is the same location as the first blue cousin.
The third turquoise cousin does not match me on chromosome 1 but does on chromosomes 3 and 4.
None of those three cousins match me on chromosome 2.
On chromosome 3, you can see that all three cousins match me on a portion of the same segment which in this case indicates that we all inherited that segment from our common ancestral couple. I know these cousins, so I already know this is a maternal match, but I can easily confirm by checking my mother’s results or using the matrix tool to be sure we all match each other. Any unknown match who matches us on this same segment also descends from this same ancestral line – meaning either Bauke and Eva, or one of their ancestral lines.

All major vendors except Ancestry provide a chromosome browser.

Chromosome painting is different.

While a chromosome browser displays your matching segments with selected matches, ethnicity chromosome painting automatically paints your ethnicity on your maternal and paternal chromosomes at each location.

Ancestry paints your ethnicity on your chromosomes by parent, by assigned world region, based on YOUR designation of maternal and paternal “sides.” My maternal chromosome is displayed on the top, and my paternal chromosome is displayed on the bottom.

With chromosome painting, there’s no way to see which matches match you on specific chromosomes. Nor does Ancestry provide you with segment information. In other words, you can’t compare a specific segment to see which of your matches match you on that segment.

However, that’s one of the great features at DNAPainter, and they’ve found a way to utilize Ancestry’s painting for that purpose.

DNAPainter estimates the segment information from Ancestry’s chromosome painting, which means you can utilize the segment information from Ancestry at DNAPainter. Having said that, I’m very skeptical of Ancestry’s painting accuracy.

Note that almost all of Ancestry’s chromosome painting covers the entire maternal or paternal chromosome with one ethnicity. In my case, three maternal chromosomes have two ethnicities, and the balance of 39 chromosomes show only one ethnicity for the entire chromosome.

That’s very suspicious, given my mixed heritage, and does not align with ethnicities at the other vendors.

Furthermore, if you look at chromosome 10 as an example, my maternal chromosome shows Scotland, and my paternal chromosome shows Ireland. My mother, who is primarily (87.5%) German, Dutch, and French, and whose ancestors I’ve confirmed through 5 generations have zero, as in no Scottish or Irish. So, in this case, the ethnicity is misattributed, which means the painting of that entire maternal chromosome is incorrect as well.

That’s not the only one. Ancestry has also attributed all of maternal chromosome 18 and half of chromosome 2 as Scottish too.

Ancestry updates their ethnicity estimates periodically, generally every year or so.

If yours hasn’t been updated recently, updates are supposed to be complete by the end of September 2023.

Ethnicity estimates are just that, and each update varies slightly, but that’s about it. The only ethnicity update that would help me is IF Ancestry “rediscovered” my Native American segments that come and go at Ancestry, AND they would include matching segment information with cousins so I can determine which of my ancestors contributed that Native segment. Then I’d know which cousins share that Native segment and could utilize their trees to isolate the common ancestor. Yes, I know, I’m hallucinating, because that’s never going to happen.

However, maybe an ethnicity update will encourage people to sign in and create trees. That would be useful.

Compare My DNA Ethnicity and Communities

Another feature that seems to be new and does NOT say “Member Access,” so should be available to everyone, is the ability to compare DNA ethnicities and communities with others.

By selecting the Compare My DNA tab, then DNA Communities, you can see which of your matches share communities with you.

Note that I don’t match my own second test exactly.

By selecting Ethnicity estimates, you can see which regions you and your matches have in common.

Please understand that this does NOT necessarily mean you share those regions due to the same ancestors!

For example, my Ferverda cousin and I may or may not share some or all of our Germanic Europe or England and Northwestern Europe ethnicity from our common ancestors – and there’s no way to know or tell without segment information and a chromosome browser.

Future Features

Ancestry’s email referenced a future feature – Communities Inheritance by parental connection.

I only have three communities at Ancestry, and I know which ones result from which ancestors.

I’m presuming that if Ancestry is referencing this new feature, it’s not too far in the future.

Parental Sides Based on Ancestry Ethnicity

In the article about SideView, I discussed how customers indicate which parent is which based on ethnicity. If you can’t do it using ethnicity results alone, you can view your closest matches, which presumes you know how you’re related to them, and select ethnicity regions based on shared regions.

These additional features are built upon the base of SideView, which is built upon a base of Ancestry’s ethnicity estimate.

Many of these features rest on your ability to accurately determine your maternal and paternal sides – either using your ethnicity results or your shared ethnicity of your known closest matches. My Mom is 50% German and 24% Dutch, with the remainder being equally divided between French/Native (Acadian) and English. My father has no German and no known French. The high percentage of German made my parents easy to separate. Had I made a mistake though, or if Ancestry makes a mistake in ethnicity attribution, such as the Scottish example I provided, all of these features that depend on an accurate parental division will also be inaccurate.

Summary

This new feature rollout was confusing to sort out since:

Some features require a full subscription
Some require the new AncestryDNA Plus subscription (or a full subscription)
Traits was previously an extra purchase but is now included with either subscription
Some features remain available with the AncestryDNA test with no subscription

I made a chart.

Feature	With DNA Test	Subscription Needed	Comment
Traits		Yes	Was an uplift, now included with either subscription
Traits by Parent		Yes	Now included
Ethnicity Estimate	Yes	No
Ethnicity by parent		Yes	Was included, now behind paywall
Ethnicity Chromosome Painter		Yes	Was included, now behind paywall
Matches by parent		Yes	Was included, now behind paywall
Compare Communities with Matches	Yes	No	Today, there is no “Member Access” label
Compare Ethnicity Estimates with Matches	Yes	No	Today, there is no “Member Access” label
Communities by Parent		Yes	Future Feature
Full Access to Matches’ Trees	Partial	Full subscription needed, not AncestryDNA Plus	Future features in email from Ancestry

Features not mentioned above remain included in the AncestryDNA test, meaning without any additional subscription:

Matching
Grouping Matches
Shared Matches
Communities
ThruLines

Opinion

I have two issues with this new rollout. Ancestry is now charging for previously included features. Secondly, many of those up-charge features are predicated upon ethnicity estimates that the customer has to divide maternally and paternally. In other words, there’s a significant possibility that you’re paying for and depending upon something inaccurate.

What bothers me the most is the fact that Ancestry giveth, and Ancestry taketh away. The SideView features were included with the original DNA test purchase price initially, but now Ancestry has pushed some of those features behind a paywall. I feel that’s disingenuous.

In the bigger picture, I’ve wondered how long companies can continue to fund new features with new test sales. The companies have to provide the results to their millions of legacy clients that now reaches back years. As the database continues to grow, the processing and storage requirements do, too – and that isn’t free.

The companies BEST able to continue to fund that development are the companies that utilize DNA tests to leverage larger and repeated sales – like Ancestry and MyHeritage records subscriptions.

Furthermore, Ancestry and 23andMe both collaborated with pharmaceutical companies, although both initial contracts have expired. Ancestry’s current collaborations are listed here.

Companies that do not utilize DNA to leverage other sales would have more motivation to place at least some of their advanced tools behind a subscription paywall. 23andMe has been doing that progressively since 2020 and now offers a “membership” for $69 per year – assuming you have a recent test. Otherwise, you have to retest for the additional cost of $229 before you can purchase the membership.

MyHeritage also limits access to full trees for DNA testers without a Premium subscription, but by comparison, they have not put any features behind a paywall that were previously included in the DNA test, nor do they have a separate DNA subscription.

Both FamilyTreeDNA and MyHeritage require a one-time unlock, $19 and $29, respectively, for advanced features if you upload a test from another testing company, meaning you didn’t test with them – but that’s entirely different from a secondary yearly subscription to access DNA features for paying customers.

FamilyTreeDNA, whose only business is DNA testing, includes all features with a DNA test. No subscription is available or required.

I’ve included this to say that I understand the need to generate revenue. My issue is that I feel like Ancestry, the largest DNA testing company, who could best afford research and development investment, essentially did a bait-and-switch with their customers by taking something away.

When ThruLines went sideways a month or so ago, I knew something was up. I suspected that Ancestry was recalculating relationships in the background for some reason. Now we know that the reason was these new features.

However, the problem with ThruLines isn’t fixed. I don’t believe many previous connections were wrong and are correct now. Cousins who match me and had common ancestors in their tree still have common ancestors in their tree and still match me – but aren’t currently connected through ThruLines. And I’m not referring to just a few.

Then, there are the issues with maternal and paternal match assignments.

Neither of these issues inspire much confidence, especially as a company begins charging for previously included features. Issues happen in IT, but the issues need to be resolved as soon as possible. The fact that these issues aren’t resolved, in addition to the required subscriptions being rolled out before the issues are resolved, makes me angry with a company many within the industry recommend in good faith.

I feel like all customers, full subscribers who want and need to utilize advanced tools to solve genealogical puzzles, along with customers who “only” tested their DNA, are being penalized.

The very least Ancestry could have done was delay the subscription rollout until they fixed the mess they made. The honorable thing would have been to only place new features behind the paywall, not taking existing features away from customers already enjoying them.

I have a full yearly subscription, so I’m covered, but if I were not, there’s nothing in the new features that I think will benefit my genealogy.

Traits doesn’t benefit genealogy
Traits by parent doesn’t benefit genealogy
Ethnicity by parent doesn’t – even if it was accurate.
Chromosome painting doesn’t – in part because the ethnicity and division is inaccurate and in part because no segment information is provided.
Matches by parent could be useful, but since it’s currently malfunctioning and is based on SideView ethnicity divisions, I don’t have much confidence in the results.
Communities by parent, a future feature, might be useful for some people, assuming parents are assigned correctly.

Since we are discussing Ancestry’s new features, I know that someone will ask if I’ve noticed the new Ancestry Dog DNA test that rolled out simultaneously.

Yes, I noticed. I suggest you read this article before purchasing any dog DNA test from any source.

There’s so much that Ancestry could do for their paying customers, whether we’ve paid for a DNA test, a subscription, or both, but instead, they’ve focused their efforts on another revenue-producing product that has nothing to do with human genealogy.

I feel like Ancestry is offering a lot of window dressing eye-candy, while what we really need are genealogical answers that are within their power to provide.

The four DNA-related features that Ancestry could provide that would be the most beneficial for genealogy would be:

DNA match search by ancestor. Not surname-only like is provided today. Not just Estes, but Moses Estes, or better yet – the Moses Estes born in 1711 who died in 1787. I have 106,000 matches, and I’m not going to scroll through what are probably thousands of never-ending unrolling matches, each of which I have to click on their tree to see if my ancestor is there. This is entirely unnecessary.
Matching segment information for matches, including triangulation. I want to confirm which ancestor I share with my matches – and prove it.
Chromosome browser – seeing is believing.
ThruLines extended back at least another two generations, from 7 to 9.

Working without these features is akin to riding a unicycle with one hand tied behind your back. I swear, sometimes I feel like Ancestry doesn’t want us to FIND our ancestors; they just want us to keep looking!

But that really doesn’t help them in the long run, either.

Helping genealogists actually identify ancestors means we have an entirely new generation to search for in those subscription records, and then another, and another. Yep, we’d have more reason than ever to subscribe!

I want more than a carrot dangling at the end of a stick. I want tools that facilitate answers. Now, for that, I’d gladly pay a subscription.

Ancestry’s ThruLines Are a Hot Mess Right Now – But Here Are Some Great Alternatives

Posted on September 3, 2023 by Roberta Estes

Right now, ThruLines at Ancestry is one hot mess.

Aside from the inherent frustration, especially over a holiday weekend when many people had planned to work on their genealogy, I’d like to say, “don’t panic.”

I don’t have any inside information about what’s going on at Ancestry, and I’ve attempted to make contact through their support page with no luck. They make talking to a person exceedingly difficult; plus, it’s a holiday weekend, and they are probably inundated.

Regardless, I have an idea of what is happening. Ancestry has been in the midst of recalculating “things,” perhaps in relation to their other changes, which I’ll write about separately in a few days.

In any event, Ancestry SURELY MUST KNOW there’s a significant problem because I imagine thousands of their customers are screaming right about now. Adding another voice won’t be helpful.

Symptoms

You may not have ThruLines at all.
If you do have ThruLines, don’t trust the information, or more to the point, don’t trust that it’s in any way complete.

I have two tests at Ancestry, both connected to different trees so that my matches and Thrulines are calculated separately for each test.

Test One

My first Ancestry test is connected to my primary tree. I’ve been amassing Thrulines cousins ever since the feature was released. I have hundreds of cousin matches descended from some of my more prolific ancestors.

Additionally, my sister’s grandchildren have tested, as have other close relatives who have connected their tests to their trees.

Today, those people are still showing on my match list, but are NOT showing as matches in ThruLines. None of them. Most of my ThruLines ancestors are showing zero matches, and the rest are only showing very few. Ancestors who had hundreds before now have 2, for example.

Here’s an example with my cousin, Erik.

My grandfather, William George Estes, shown in Erik’s tree, above, is his great-grandfather. Erik is my half first cousin, once removed, and we share 417 cM over 16 segments.

Yet, looking at my ThruLine for William George Estes, neither he nor my other cousins are shown as matches. Same for William George’s parents, and so forth.

ThruLines is VERY ill right now.

Test Two

My second DNA test at Ancestry is even worse. There are no ThruLines calculated, even though my DNA is tree-attached, and I had ThruLines previously.

I see this message now, and I can’t even begin to tell you how irritating this is – in part because it suggests the problem is my fault. It’s clearly not. My tree hasn’t changed one bit. I’m not alone, either. I’ve seen other people posting this same message.

And yes, if you’re thinking that there is absolutely no excuse for this – you’re right.

However, outrage isn’t good for us and won’t help – so let’s all do something else fun and productive instead.

Productive Genealogy Plans

Here are some productive suggestions.

Be sure your autosomal DNA file is uploaded to both MyHeritage and FamilyTreeDNA. You’ll receive new matches at each vendor that aren’t elsewhere. Here are step-by-step instructions if you need them. Here’s the link to upload to MyHeritage.

At MyHeritage:

Check for new DNA matches and triangulation.
Work on your Theories of Family Relativity.
Check for new record matches.

Select an ancestor in your tree at MyHeritage, then click on “research this person.” If you don’t have a tree at MyHeritage, you can download a copy of your tree from Ancestry or elsewhere and upload it to MyHeritage.
If you don’t have a records subscription at MyHeritage, now might be a good time to sign up for their subscription with a free trial, here,

At FamilyTreeDNA:

Check for new Family Finder autosomal matches and see if they are assigned either maternally or paternally using Family Matching.
If you have not tested your mitochondrial DNA (mtDNA), which descends from your mother’s mother’s mother’s matrilineal line, order that test for yourself.
If you’re a male, order or upgrade your test to the Big Y-700 to learn about your direct patrilineal (surname) line, including the Discover tool and Globetrekker.

Build your haplogroup pedigree chart by locating people through different companies descended from each ancestor in your tree through the appropriate line of descent, and see if they have or will take a Y-DNA or mtDNA test.
Tests are on sale right now, and there’s no subscription required at FamilyTreeDNA for anything.
Check Y-DNA and mtDNA tests to see if there are new matches and if you share a common ancestor.

At 23andMe:

Check for new matches and triangulation.
Check to see if 23andMe has added any of your new matches to your genetic tree.

Remember, the parental sides are typically accurate, but the exact placement may not be, and 23andMe deals poorly with half-relationships. It’s certainly still worth checking though, because 23andMe does a lot of heavy lifting for you.

DNAPainter

For me, the most productive thing to do this weekend would be to copy the segment information from new matches with whom I can identify common ancestors at FamilyTreeDNA, MyHeritage and 23andMe – the vendors who provide segment data – and paint those segments to DNAPainter.

Not only does DNAPainter allow me to consolidate my match data in one place, DNAPainter provides the ability for me to confirm ancestors through triangulation, and to assign unknown matches to ancestors as well.

As you can see, I’ve successfully assigned about 90% of my segments to an ancestor, meaning I’ve confirmed descent from that ancestor based on my autosomal matches’ descent from that same ancestor – preferably through another child. Will new matches propel me to 91%? I hope so.

What percentage can you or have you been able to assign?

If you need help getting started, or ideas, I’ve written about DNAPainter several times and provided a compiled resource library of those articles, here.

Have fun!!!

Which DNA Test Should I Buy? And Why?

Posted on June 21, 2023 by Roberta Estes

Which DNA test should I buy, and why?

I receive questions like this often. As a reminder, I don’t take private clients anymore, which means I don’t provide this type of individual consulting or advice. However, I’m doing the next best thing! In this article, I’m sharing the step-by-step process that I utilize to evaluate these questions so you can use the process too.

It’s important to know what questions to ask and how to evaluate each situation to arrive at the best answer for each person.

Here’s the question I received from someone I’ll call John. I’ve modified the wording slightly and changed the names for privacy.

I’m a male, and my mother was born in Charleston, SC. My maternal grandmother’s maiden name was Jones and a paternal surname was Davis. The family was supposed to have been Black, Dutch, Pennsylvania Dutch, and Scots-Irish…only once was I told I was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.

Do I have enough reasonable information to buy a test, and which one?

Please note that it’s common for questions to arrive without all the information you need to provide a sound answer – so it’s up to you to ask those questions and obtain clarification.

Multiple Questions

There are actually multiple questions here, so let me parse this a bit.

John never mentioned what his testing goal was.
He also never exactly said how the paternal line of Davis was connected, so I’ve made an assumption. For educational purposes, it doesn’t matter because we’re going to walk through the evaluation process, which is the same regardless.
John did not include a tree or a link to a tree, so I created a rudimentary tree to sort through this. I need the visuals and normally just sketch it out on paper quickly.
Does John have enough information to purchase a test?
If so, which test?

There is no “one size fits all” answer, so let’s discuss these one by one.

Easy Answers First

The answer to #4 is easy.

Anyone with any amount of information can purchase a DNA test. Adoptees do it all the time, and they have no prior information.

So, yes, John can purchase a test.

The more difficult question is which test, because that answer depends on John’s goals and whether he’s just looking for some quick information or really wants to delve into genealogy and learn. Neither approach is wrong.

Many people think they want a quick answer – and then quickly figure out that they really want to know much more about their ancestors.

I wrote an article titled DNA Results – First Glances at Ethnicity and Matching for new testers, here.

Goals

Based on what John said, I’m going to presume his goals are probably:

To prove or disprove the family oral history of Black, Dutch, Pennsylvania Dutch (which is actually German,) Scots-Irish, and potentially Native American.
John didn’t mention actual genealogy, which would include DNA matches and trees, so we will count that as something John is interested in secondarily. However, he may need genealogy records to reach his primary goal.

If you’re thinking, “The process of answering this seemingly easy question is more complex than I thought,” you’d be right.

Ethnicity in General

It sounds like John is interested in ethnicity testing. Lots of people think that “the answer” will be found there – and sometimes they are right. Often not so much. It depends.

The great news is that John really doesn’t need any information at all to take an autosomal DNA test, and it doesn’t matter if the test-taker is male or female.

To calculate each tester’s ethnicity, every testing company compiles their own reference populations, and John will receive different results at each of the major companies. Each company updates their ethnicity results from time to time as well, and they will change.

Additionally, each company provides different tools for their customers.

The ethnicity results at different companies generally won’t match each other exactly, and sometimes the populations look quite different.

Normally, DNA from a specific ancestor can be found for at least 5 or 6 generations. Of course, that means their DNA, along with the DNA from all of your other ancestors is essentially combined in a communal genetic “pot” of your chromosomes, and the DNA testing company needs to sort it out and analyze your DNA for ethnicity.

DNA descended from ancestors, and their populations, further back in people’s trees may not be discerned at all using autosomal DNA tests.

A much more specific “ethnicity” can be obtained for both the Y-DNA line, which is a direct patrilineal line for men (blue arrow,) and the mitochondrial DNA line (pink arrows,) which is a direct matrilineal line for everyone, using those specific tests.

We will discuss both of those tests after we talk about the autosomal tests available from the four major genealogy DNA testing companies. All of these tools can and should be used together.

Let’s Start with Native American

Let’s evaluate the information that John provided.

John was told that he “was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.”

We need to evaluate this part of his question slightly differently.

I discussed this in the article, Ancestral DNA Percentages – How Much of Them is in You?

First, we need to convert generations to 16^ths.

You have two ancestors in your parent’s generation, four in your grandparents, and so forth. You have 16 great-great-grandparents. So, if John was 3/16^th Native, then three of his great-great-grandparents would have been fully Native, or an equivalent percentage. In other words, six ancestors in that generation could have been half-Native. Based on what John said, they would have come from his mother’s side of the tree. John is fortunate to have that much information to work with.

He told us enough about his tree that we can evaluate the statement that he might be 3/16^ths Native.

Here’s the tree I quickly assembled in a spreadsheet based on John’s information.

His father, at left, is not part of the equation based on the information John provided.

On his mother’s side, John said that Grandfather Davis is supposed to be three-quarters Native, which translates to 12/16^ths. Please note that it would be extremely beneficial to find a Y-DNA tester from his Davis line, like one of his mother’s brothers, for example.

John said that his Grandmother Jones is supposed to be 100% Native, so 16/16^ths.

Added together, those sum to 28/32, which reduces down to 14/16^th or 7/8^th for John’s mother.

John would have received half of his autosomal DNA from his mother and half from his non-Native father. That means that if John’s father is 100% non-Native, John would be half of 14/16^ths or 7/16^ths, so just shy of half Native.

Of course, we know that we don’t always receive exactly 50% of each of our ancestors’ DNA (except for our parents,) but we would expect to see something in the ballpark of 40-45% Native for John if his grandmother was 100% Native and his grandfather was 75%.

Using simple logic here, for John’s grandmother to be 100% Native, she would almost assuredly have been a registered tribal member, and the same if his grandfather was 75% Native. I would think that information would be readily available and well-known to the family – so I doubt that this percentage is accurate. It would be easy to check, though, on various census records during their lifetimes where they would likely have been recorded as “Indian.” They might have been in the special “Indian Census” taken and might be living on a reservation.

It should also be relatively easy to find their parents since all family members were listed every ten years in the US beginning with the 1850 census.

The simple answer is that if John’s grandparents had as much Native as reported, he would be more than 3/16^th – so both of these factoids cannot simultaneously be accurate. But that does NOT mean neither is accurate.

John could be 7/8^th or 40ish%, 3/16^th or 18ish%, or some other percentage. Sometimes, where there is smoke, there is fire. And that seems to be the quandary John is seeking to resolve.

Would Ethnicity/Population Tests Show This Much Native?

Any of the four major testing companies would show Native for someone whose percentage would be in the 40% or 18% ballpark.

The easiest ethnicities to tell apart from one another are continental-level populations. John also stated that he thinks he may also have Black ancestry, plus Dutch, Pennsylvania Dutch (German), and Scots-Irish. It’s certainly possible to verify that using genealogy, but what can DNA testing alone tell us?

How far back can we expect to find ethnicities descending from particular ancestors?

In this table, you can see at each generation how many ancestors you have in that generation, plus the percentage of DNA, on average, you would inherit from each ancestor.

All of the major DNA testing companies can potentially pick up small trace percentages, but they don’t always. Sometimes one company does, and another doesn’t. So, if John has one sixth-generation Native American ancestor, he would carry about 1.56% Native DNA, if any.

Sometimes a specific ethnicity is not found because, thanks to random recombination, you didn’t inherit any of that DNA from those ancestors. This is why testing your parents, grandparents, aunts, uncles, and siblings can be very important. They share your same ancestors and may have inherited DNA that you didn’t that’s very relevant to your search.
Sometimes it’s not found because the reference populations and algorithms at that testing company aren’t able to detect that population or identify it accurately, especially at trace levels. Every DNA testing company establishes their own reference populations and writes internal, proprietary ethnicity analysis algorithms.
Sometimes it’s not found because your ancestor wasn’t Native or from that specific population.
Sometimes it’s there, but your population is called something you don’t expect.

For example, you may find Scandinavian when your ancestor was from England or Ireland. The Vikings raided the British Isles, so while some small amount of Scandinavian is not what you expect, that doesn’t mean it‘s wrong. However, if all of your family is from England, it’s not reasonable to have entirely Scandinavian ethnicity results.

It’s also less likely as each generation passes by that the information about their origins gets handed down accurately to following generations. Most non-genealogists don’t know the names of their great-grandparents, let alone where their ancestors were from.

Using a 25-year average generation length, by the 4^th generation, shown in the chart above, you have 16 ancestors who lived approximately 100 years before your parents were born, so someplace in the mid-1800s. It’s unlikely for oral history from that time to survive intact. It’s even less likely from a century years earlier, where in the 7^th generation, you have 128 total ancestors.

The best way to validate the accuracy of your ethnicity estimates is by researching your genealogy. Of course, you need to take an ethnicity test, or two, in order to have results to validate.

Ethnicity has a lot more to offer than just percentages.

Best Autosomal Tests for Native Ethnicity

Based on my experience with people who have confirmed Native ancestry, the two best tests to detect Native American ethnicity, especially in smaller percentages, are both FamilyTreeDNA and 23andMe.

Click images to enlarge

In addition to percentages, both 23andMe and FamilyTreeDNA provide chromosome painting for ethnicity, along with segment information in download files. In other words, they literally paint your ethnicity results on your chromosomes.

They then provide you with a file with the “addresses” of those ethnicities on your chromosomes, which means you can figure out which ancestors contributed those ethnicity segments.

The person in the example above, a tester at FamilyTreeDNA, is highly admixed with ancestors from European regions, African regions and Native people from South America.

Trace amounts of Native American with a majority of European heritage would appear more like this.

You can use this information to paint your chromosome segments at DNAPainter, along with your matching segments to other testers where you can identify your common ancestors. This is why providing trees is critically important – DNA plus ancestor identification with our matches is how we confirm our ancestry.

This combination allows you to identify which Native (or another ethnicity) segments descended from which ancestors. I was able to determine which ancestor provided that pink Native American segment on chromosome 1 on my mother’s side.

I’ve provided instructions for painting ethnicity segments to identify their origins in specific ancestors, here.

Autosomal and Genealogy

You may have noticed that we’ve now drifted into the genealogy realm of autosomal DNA testing. Ethnicity is nice, but if you want to know who those segments came from, you’ll need:

Autosomal test matching to other people
To identify your common ancestor with as many matches as you can
To match at a company who provides you with segment information for each match
To work with DNAPainter, which is very easy

The great news is that you can do all of that using the autosomal tests you took for ethnicity, except at Ancestry who does not provide segment information.

Best Autosomal Test for Matching Other Testers

The best autosomal test for matching may be different for everyone. Let’s look at some of the differentiators and considerations.

If you’re basing a testing recommendation solely on database size, which will probably correlate to more matches, then the DNA testing vendors fall into this order:

If you’re basing that recommendation on the BEST, generally meaning the closest matches for you, there’s no way of knowing ahead of time. At each of the four DNA testing companies, I have very good matches who have not tested elsewhere. If I weren’t in all four databases, I would have missed many valuable matches.

If you’re basing that recommendation on which vendor began testing earliest, meaning they have many tests from people who are now deceased, so you won’t find their autosomal tests in other databases that don’t accept uploads, the recommended testing company order would be:

FamilyTreeDNA with tests from people who originally tested two decades ago.
23andMe
Ancestry
MyHeritage

If you’re basing that recommendation on matches to people who live in other countries, the order would be:

Ancestry and 23andMe are very distant third/fourth because they did not sell widely outside the US initially and still don’t sell in as many countries as the others, meaning their testers’ geography is more limited. However, Ancestry is also prevalent in the UK.

If you’re basing that recommendation on segment information and advanced tools that allow you to triangulate and confirm your genetic link to specific ancestors, the order would be:

Ancestry does NOT provide any segment information.

If you’re basing that recommendation on unique tools provided by each vendor, every vendor has something very beneficial that the others don’t.

In other words, there’s really no clear-cut answer for which single autosomal DNA test to order. The real answer is to be sure you’re fishing in all the ponds. The fish are not the same. Unique people test at each of those companies daily who will never be found in the other databases.

Test at or upload your DNA to all four DNA testing companies, plus GEDmatch. Step-by-step instructions for downloading your raw data file and uploading it to the DNA testing companies who accept uploads can be found, here.

Test or Upload

Not all testing companies accept uploads of raw autosomal DNA data files from other companies. The good news is that some do, and it’s free to upload and receive matches.

Two major DNA testing companies DO NOT accept uploads from other companies. In other words, you have to test at that company:

Two testing companies DO accept uploads from the other three companies. Uploads and matching are free, and advanced features can be unlocked very cost effectively.

FamilyTreeDNA – free matching and $19 unlock for advanced features
MyHeritage – free matching and $29 unlock.for advanced features

I recommend testing at both 23andMe and Ancestry and uploading one of those files to both FamilyTreeDNA and MyHeritage, then purchasing the respective unlocks.

GEDmatch

GEDmatch is a third-party matching site, not a DNA testing company. Consider uploading to GEDmatch because you may find matches from Ancestry who have uploaded to GEDmatch, giving you access to matching segment information.

Other Types of DNA

John provided additional information that may prove to be VERY useful. Both Y-DNA and mitochondrial DNA can be tested as well and may prove to be more useful than autosomal to positively identify the origins of those two specific lines.

Let’s assume that John takes an autosomal test and discovers that indeed, the 3/16^th Native estimate was close. 3/16^th equates to about 18% Native which would mean that three of his 16 great-great-grandparents were Native.

John told us that his Grandmother Jones was supposed to be 100% Native.

At the great-great-grandparent level, John has 16 ancestors, so eight on his mother’s side, four from maternal grandmother Jones and four from his maternal grandfather Davis.

John carries the mitochondrial DNA of his mother (red boxes and arrows,) and her mother, through a direct line of females back in time. John also carries the Y-DNA of his father (dark blue box, at left above, and blue arrows below.)

Unlike autosomal DNA which is admixed in every generation, mitochondrial DNA (red arrows) is inherited from that direct matrilineal line ONLY and never combines with the DNA of the father. Mothers give their mitochondrial DNA to both sexes of their children, but men never contribute their mitochondrial DNA to offspring. Everyone has their mother’s mitochondrial DNA.

Because it never recombines with DNA from the father, so is never “watered down,” we can “see” much further back in time, even though we can’t yet identify those ancestors.

However, more importantly, in this situation, John can test his own mitochondrial DNA that he inherited from his mother, who inherited it from her mother, to view her direct matrilineal line.

John’s mitochondrial DNA haplogroup that will be assigned during testing tells us unquestionably whether or not his direct matrilineal ancestor was Native on her mother’s line, or not. If not, it may well tell us where that specific line originated.

You can view the countries around the world where Y-DNA haplogroups are found, here, and mitochondrial haplogroups, here.

If John’s mitochondrial DNA haplogroup is Native, that confirms that one specific line is Native. If he can find other testers in his various lines to test either their Y-DNA or mitochondrial DNA, John can determine if other ancestors were Native too. If not, those tests will reveal the origins of that line, separate from the rest of his genealogical lines.

Although John didn’t mention his father’s line, if he takes a Y-DNA test, especially at the Big Y-70 0 level, that will also reveal the origins of his direct paternal line. Y-DNA doesn’t combine with the other parent’s DNA either, so it reaches far back in time too.

Y-DNA and mitochondrial DNA tests are laser-focused on one line each, and only one line. You don’t have to try to sort it out of the ethnicity “pot,” wondering which ancestor was or was not Native.

My Recommendation

When putting together a testing strategy, I recommend taking advantage of free uploads and inexpensive unlocks when possible.

To confirm Native American ancestry via ethnicity testing, I recommend testing at 23andMe and uploading to FamilyTreeDNA, then purchasing the $19 unlock. The free upload and $19 unlock are less expensive than testing there directly.
For matching, I recommend testing at Ancestry and uploading to MyHeritage, then unlocking the MyHeritage advanced features for $29, which is less expensive than retesting. Ancestry does not provide segment information, but MyHeritage (and the others) do.

At this point, John will have taken two DNA tests, but is now in all four databases, plus GEDmatch if he uploads there.

For genealogy research on John’s lines to determine whether or not his mother’s lines were Native, I recommend an Ancestry and a MyHeritage records subscription, plus using WikiTree, which is free.
To determine if John’s mother’s direct matrilineal female line was Native, I recommend that John order the mitochondrial DNA test at FamilyTreeDNA.
When ordering multiple tests, or uploading at FamilyTreeDNA, be sure to upload/order all of one person’s tests on the same DNA kit so that those results can be used in combination with each other.

Both males and females can take autosomal and mitochondrial DNA tests.

To discover what he doesn’t know about his direct paternal, meaning John’s surname line – I recommend the Big Y-700 test at FamilyTreeDNA.

Only males can take a Y-DNA test, so women would need to ask their father, brother, or paternal uncle, for example, to test their direct paternal line.

If John can find a male Davis from his mother’s line, I recommend that he purchase the Big Y-700 test at FamilyTreeDNA for that person, or check to see if someone from his Davis line may have already tested by viewing the Davis DNA Project. Like with mitochondrial DNA, the Y-DNA haplogroup will tell John the origins of his direct Davis male ancestor – plus matching of course. He will be able to determine if they were Native, and if not, discover the origins of the Davis line.
For assigning segments to ancestors and triangulating to confirm descent from a common ancestor, I recommend 23andMe, MyHeritage, FamilyTreeDNA and GEDmatch, paired with DNAPainter as a tool.

Shopping and Research List

Here are the tests and links recommended above:

23andMe
Ancestry
MyHeritage Upload with free matching, then $29 unlock
FamilyTreeDNA Upload with free matching, then $19 unlock
GEDmatch free upload, then $9.95 monthly subscription for advanced tools if needed
FamilyTreeDNA mitochondrial DNA test (using the same kit number as the upload)
FamilyTreeDNA Big Y-700 for John and also for Davis male tester if he can find one
DNAPainter for uploading ethnicity painting plus segments that can be identified to specific ancestors to determine which ancestors provided which ethnicity segments
MyHeritage records subscription (free trial) (for genealogy research)
Ancestry subscription for genealogy research

More Than He Asked

I realize this answer is way more than John expected or even knew to ask. That’s because there is often no “one” or “one best” answer. There are many ways to approach the question after the goal is defined, and the first “answer” received may be a bit out of context.

For example, let’s say John has 2% Native ancestry and took a test at a vendor who didn’t detect it. John would believe he had none. But a different vendor might find that 2%. If it’s on his mother’s direct matrilineal line, mitochondrial DNA testing will confirm, or refute Native, beyond any doubt, regardless of autosomal ethnicity results – but only for that specific ancestral line.

Autosomal DNA can suggest Native across all your DNA, but Y-DNA and mitochondrial DNA confirm it for each individual ancestor.

Even when autosomal testing does NOT show Native American, or African, for example, it’s certainly possible that it’s just too far back in time or has not been passed down during random recombination, but either Y-DNA or mitochondrial DNA will unquestionably confirm (or refute) the ancestry in question if the right person is tested.

This is exactly why I attempt to find a cousin who descends appropriately from every ancestor and provide testing scholarships. It’s important to obtain Y-DNA and mitochondrial DNA information for each ancestor.

Which Test Should I Order?

What steps will help you decide which test or tests to take?

Define your testing goal.
Determine if your Y-DNA or mitochondrial DNA will help answer the question.
Determine if you need to find ancestors another generation or two back in time to get the most benefit from DNA testing. In our example, if John discovered that both of his grandparents were enrolled tribal members, that’s huge, and the tribe might have additional information about his family.
Subscribe to Ancestry and MyHeritage records collections as appropriate to perform genealogical research. Additional information not only provides context for your family, it also provides you with the ability to confirm or better understand your ethnicity results.
Extend your tree so that you can obtain the best results from the three vendors who support trees; Ancestry, FamilyTreeDNA, and MyHeritage. All three use trees combined with DNA tests to provide you with additional information.
Order 23andMe and Ancestry autosomal DNA tests.
Either test at or upload one of those tests to MyHeritage, FamilyTreeDNA, and GEDmatch.
If a male, order the Big Y-700 DNA test. Or, find a male from your ancestral line who has taken or will take that test. I always offer a testing scholarship and, of course, share the exciting results!
Order a mitochondrial DNA test for yourself and for appropriately descended family members to represent other ancestors. Remember that your father (and his siblings) all carry your paternal grandmother’s mitochondrial DNA. That’s often a good place to start after testing your own DNA.
If your parents or grandparents are alive, or aunts and uncles, test their autosomal DNA too. They are (at least) one generation closer to your ancestors than you are and will carry more of your ancestors’ DNA.
Your siblings will carry some of your ancestors’ DNA that you do not, so test them too if both of your parents aren’t available for testing.

Enjoy!!!

AARP Member? Save 30% On Your Ancestry Membership

Posted on June 14, 2023 by Roberta Estes

If you’re an AARP member, you are eligible to receive a 30% discount on your subscription at Ancestry.com.

My subscription was going to expire. It couldn’t auto-renew because my credit card had expired which turned out to be a happy accident. I waited until about 10 days before expiration to call and renew. I wanted to see if any discounts were available.

You can see when your subscription expires by clicking on the down arrow by your name, then Account Settings.

The AARP Discount

Here’s how the AARP discount works:

You need to call Ancestry at 800-401-1789 in the US and talk to a customer service representative. The person I spoke with was very helpful but neglected to mention that my current subscription was not allowed to run its course BEFORE the new subscription took effect. I lost the remaining days.
If you’re calling from outside the US, you’ll probably need to connect via chat with a Virtual Assistance to obtain a phone number that will work for you.
You need to provide your AARP membership number – and they do verify the number.
If you don’t have your card handy, you can find your account number above your name on the AARP correspondence and/or their membership newspaper/flyer.
If you pay for your AARP membership for either three or five years at a time instead of one year, you’ll need to contact AARP to get a new number yearly. Yea, I know this doesn’t make sense, but that’s how AARP works, apparently. I was fortunate because I joined last fall.
I don’t know if this discount applies to partial-year memberships or if you select monthly payments. You can discuss that with the Ancestry representative.
If you select auto-renew, at this same time next year your membership WILL RENEW AT THE THEN-CURRENT RATE. This means Ancestry does NOT renew your membership at the AARP discount rate. You’ll need to call Ancestry before your membership auto-renews to obtain that discount every year.

Is what you’ll save worth it? It was for me. I subscribe to the World Explorer Membership and saved a little more than $100. I also took advantage of this opportunity to make sure my other account information was up to date.

Don’t Cheat Yourself

After I paid, I made an unpleasant discovery.

My subscription expired the following week, during the first week of June, and what I didn’t realize was that the new membership took effect on the day I called and made the payment – May 27^th. So, I essentially got cheated out of about ten days of the subscription I had already paid for. That’s not right, and I was not informed of that “detail.”

Apparently, I should have let the subscription expire or at least waited until the last day to call. Don’t make my mistake.

My subscription renews on May 27 of next year. I’m putting a note in my calendar to check on this a month in advance to ensure this will NOT auto-renew. I attempted to simply remove my credit card information to prevent auto-renewal from occurring, but the system would not allow me to remove my current credit card information without replacing it with a different card.

I can probably have them remove it if I call again.

I suspect I’ll need to cancel my subscription next year when I call, then resubscribe using my AARP number. If you’re thinking to yourself, “This is a pain,” it surely is.

It’s too bad this is so challenging, but regardless, with a little perseverance, if you have an AARP number, you can obtain a significant discount. Don’t let this benefit go unclaimed.

You’ll save enough to buy another DNA test at Ancestry or maybe elsewhere.

If you aren’t an AARP member but are a member of other organizations, genealogy, or heritage societies, you may qualify for a discount via that membership. Some of those might even result in a larger percentage discount than AARP. You’ll need to contact Ancestry to see. They won’t give you the membership list. You have to provide them with a list of your memberships.

I’ve also been told, but can’t verify, that when Ancestry has a 50% off special for gift subscriptions only, you can call, cancel your subscription, purchase a gift subscription, and gift it to yourself.

If you know of other Ancestry discounts for specific organizations or other ways to obtain discounts, please post them in the blog comments.

Good luck!

Comparing DNA Results – Different Tests at the Same Testing Company

Posted on May 18, 2023 by Roberta Estes

Several people have asked about different tests at the same DNA testing company. They wondered if matching is affected, meaning whether your matches are different if you have two different tests at the same company. Specifically, they asked if you are better off purchasing a test AT a DNA testing vendor that allows uploads, rather than uploading a test from a different vendor. Does it make a difference to the tester or their matches? Do they have the same matches?

These are great questions, and the answer isn’t conclusive. It varies based on several factors.

Having multiple tests at the same DNA testing company can occur in three ways:

The same person tests twice at the same DNA testing company.
The same person tests once at the DNA testing company and uploads a test from a different testing company. Only two of the primary four DNA testing companies accept uploads from other vendors – FamilyTreeDNA and MyHeritage.
The same person uploads two different files from other DNA testing companies to the DNA testing company in question. For example, the DNA company could be FamilyTreeDNA and the two uploaded DNA files could be from either MyHeritage, 23andMe or Ancestry.

All DNA testing companies allow users to download their raw DNA data files. This enables the tester to upload their DNA file to the vendors who accept uploaded files. Both FamilyTreeDNA and MyHeritage provide matching for free, but advanced tools require a small unlock fee of $19 and $29, respectively.

Testing Company	Accepts Uploads from Other Companies	Download Upload Instructions
23andMe	No	Instructions here
Ancestry	No	Instructions here
FamilyTreeDNA	Yes, some	Instructions here
MyHeritage	Yes, some	Instructions here

I wrote about developing a DNA testing and transfer/upload strategy, here, and about which companies accept which tests, here.

Not all DNA files are created equal. Therefore, not all files from vendors are compatible with other vendors for various reasons.

Multiple Tests at the Same DNA Testing Company

I have at least two tests at each of the four major vendors. I did this for research purposes, meaning to write articles to share with you.

If you actually test twice at a vendor, meaning purchase two separate tests and take them yourself, you will have two test results at that testing company. At some companies, specifically 23andMe, if you purchase a new test through their “upgrade” procedure, you won’t have two tests, just the newer one.

However, if you’re testing at the DNA testing company, and also uploading, I generally don’t recommend more than one test at each vendor. All it really does is clog up people’s match lists with no or little additional benefit. At 23andMe, with their restrictions on the size of your match list, if everyone had two tests, the effective match limit would be half of their stated limit of about 1500 matches for earlier testers and about 5000 for current testers with subscriptions.

So, in essence, I’m telling you to “do as I say, not as I do.” We all have better things to do with our money rather pay for the same test twice. If you haven’t tested your Y-DNA or mitochondrial DNA, that’s much more beneficial than two autosomal tests at one vendor.

Chips and Chip Evolution

Before we begin the side-by-side comparison, let’s briefly discuss DNA testing chips and how they work.

Each DNA testing company purchases DNA processing equipment. Illumina is the big dog in this arena. Illumina defines the capacity and structure of each chip. In part, how the testing companies use that capacity, or space on each chip, is up to each company. This means that the different testing companies test many of the same autosomal DNA SNP locations, but not all of the same locations.

Furthermore, the individual testing companies can specify a number of “other” locations to be included on their chip, up to the chip maximum size limit. The testing companies who offer Y-DNA or mitochondrial DNA haplogroups from autosomal tests use part of their chip array space for selected known haplogroup-defining SNP locations. This does NOT mean that Y-DNA or mitochondrial DNA is autosomal, just that the testing company used part of their chip array space to target these SNPs in your genome. Of course, for your most refined haplogroup and Y-DNA or mitochondrial DNA matching, you have to take those specific tests at FamilyTreeDNA .

This means that each testing company includes and reports many of the same, but also some different SNP locations when they scan your DNA.

In the lab, after your DNA is extracted from either your saliva or the cheek swab, it’s placed on this array chip which is then placed in the processing equipment.

There are several steps in processing your DNA. Each DNA location specified on the chip is scanned and read multiple times, and the results are recorded. The final output is the raw DNA results file that you see if/when you download your raw DNA file.

Here’s an example from my file. The RSID is the reference SNP cluster ID which is the naming convention used for specific SNPs. It’s not relevant to you, but it is to the lab, along with the chromosome number and position, which is in essence the address on the chromosome.

In the Result column, your file reports one nucleotide (T, A, C or G) that you inherited from each parent at each tested position. They are not listed in “parent order” because your DNA is not organized in that fashion. There’s no way for the lab to know which nucleotide came from which parent, unless they are the same, of course. You can read about nucleotides, here.

When you upload your raw DNA file to a different DNA testing company (vendor), they have to work with a file that isn’t entirely compatible with the files they generate, or the other files uploaded from other DNA testing companies.

In addition to dealing with different file formats and contents from multiple DNA vendors, companies change their own chips and file structure from time to time. In some cases, it’s a forced change by the chip manufacturer. Other times, the vendors want to include different locations or make improvements. For example, with 23andMe’s focus on health, they probably add new medically related SNP locations regularly. Regardless of why, some DNA files include locations not included in other files and are not 100% compatible.

Looking at the first few entries in my example file above, let’s say that the testing vendor included the first ten positions, but an uploaded file from another company did not. Or perhaps the chip changed, and a different version of the company’s own file contains different positions.

DNA testing companies have to “fill in the blanks” for compatibility, and they do this using a technique called imputation. Illumina forced their customers to adopt imputation in 2017 when they dropped the capacity of their chip. I was initially quite skeptical, but imputation has worked surprisingly well. Some of the matching differences you will see when comparing the results of two different DNA files is a result of imputation.

I wrote about imputation in an early article here. Please note the companies have fixed many issues with imputation and improved matching greatly, but the concepts and imputation processes still apply. The downloaded raw data files are your results BEFORE imputation, meaning that it’s up to any company where you upload to process your raw file in the same way they would process a file that they generated. A lot goes on behind the scenes when you upload a file to a DNA testing company.

At both 23andMe and Ancestry, you know that all of your matches tested there, meaning they did not upload a file from another testing company. You don’t know and can’t tell what chip was utilized when your matches tested. The only way to determine a chip testing version, aside from knowing the date or remembering the chip version from when you tested, is to look at the beginning of the raw data download file, although not all files contain that information.

Ok, now that you understand the landscape, let’s look at my results at each company.

23andMe

I tested twice at 23andMe on two different chip versions, V3 and V4, which tested some different locations of my DNA. Neither of these chips is the current version. I originally tested twice to evaluate the differences between the two test versions which you can read about, here.

23andMe named their ethnicity results Ancestry Composition.

They last updated my V3 test’s Ancestry Composition results on July 28, 2021.

The percentages are shown at left, and the country locations are highlighted at right for my 23andMe V3 test.

Click to enlarge any graphic

The 23andMe V4 test was also updated for the last time on July 28, 2021.

The ethnicity results differ substantially between the two chip versions, even though they were both updated on the same date.

In October of 2020, in an effort to “encourage” their customers to pay for a new test on their V5 chip, 23andMe announced that there would be no ethnicity updates on older tests. So, I really don’t know for sure when my tests were actually updated. Just note how different the results are. It’s also worth mentioning that 23andMe does not show trace amounts on their map, so even though my Indigenous American results were found, they aren’t displayed on the map.

Indigenous is, however, shown in yellow on their DNA Chromosome Painting.

No other testing company restricts updates, penalizing their customers who purchased earlier versions of tests.

Matches at 23andMe

23andMe limits your matches to about 1500 unless you have purchased the current test, including health AND pay for an annual $69 subscription which buys you about 5000 matches. I have not purchased this test.

Your number of actual matches displayed/retained is also affected by how many people you have communicated with, or at least initiated communications with. 23andMe does not roll those people off of your match list.

I have 1803 matches on both of my tests, meaning I’ve reached out to about 300 people who would have otherwise been removed from my match list. 23andMe retains your highest matches, deleting lower matches after you reach the maximum match threshold.

I’ve randomly evaluated several of the same matches at each vendor, at least five maternal and five paternal, separated by a blank row. I wanted to determine whether they match me on the same number of centimorgans, meaning the same amount of DNA, on both tests, and the same number of segments.

Match	23and Me V3	23and Me V4
Patricia	292 cM – 12 segments	Same as V3
Joe	148 cM, 8 segments	Same
Emily	73 cM, 4 segs	72 cM, 4 seg
Roland	27 cM, 1 seg	Same
Ian	62 cM, 4 seg	Same

Stacy	469 cM, 16 segments	482 cM, 16 segments
Harold	134 cM, 6 segments	Same
Dean	69 cM, 3 seg	Same
Carl	95 cM, 4 seg	Same
Debbie	83 cM, 4 seg	84 cM, 4 seg

As you can see, the matches are either exact or xclose.

Please note that bolded matches are also found at another company. I will include a summary table at the end comparing the same match across multiple vendors.

23and Me Summary

The 23andMe V3 and V4 match results are very close. Since the match limit is the same, and the results are so close between tests, they are essentially identical in terms of matching.

The ethnicity results are similar, but the V4 test reflects a broader region. Italian baffles me in both versions.

Ethnicity should never be taken at face value at any DNA testing company, especially with smaller percentages which could be noise or a combination of other regions which just happens to resemble Italy, in my case.

I don’t know what type of comparison the current chip would yield since I suspect it has more medical and less genealogical SNPs on board.

Reprocessing Tests

This is probably a good place to note that it’s very expensive for any company to update their customer’s ethnicity results because every single customer’s DNA results file must be completely rerun. Note that this does not mean their DNA itself is retested. The output raw data file is reprocessed using a new algorithm.

Rerunning means reprocessing that specific portion of every test, meaning the vendors must rent “time in the cloud.” We are talking millions of dollars for each run. I don’t know how much it costs per test, but think about the expense if it takes $1 to rerun each test in the vendor’s database. Ancestry has more than 20 million tests.

While we, as consumers, are always chomping at the bit for new and better ethnicity results – the testing companies need to be sure it really is “better,” not just different before they invest the money to reprocess and update results.

This is probably why 23andMe decided to cease updating older kits. The newer tests require a subscription which is recurring revenue.

The same is true when DNA testing companies need to rematch their entire user base. This happens when the criteria for matching changes. For example, Ancestry purged a large number of matches for all of their customers back in 2020. While match algorithm changes necessitate rematching, with associated costs, this change also provided Ancestry with the huge benefit of eliminating approximately half of their customer’s matches. This freed up storage space, either physically in their data center or space rented in the cloud, representing substantial cost-savings.

How long can a DNA testing company reasonably be expected to continue investing in a product which never generates additional revenue but for which the maintenance and reinvestment costs never end?

Ancestry and MyHeritage both hope to offset the expenses of maintaining their customer’s DNA tests and providing free updates by selling subscriptions to their record services. 23andMe wants you to purchase a new test and a yearly subscription. FamilyTreeDNA wants you to purchase a Big Y-DNA and mitochondrial DNA test.

OK, now let’s look at my matches at Ancestry.

Ancestry

I’ve taken two Ancestry tests, V1 and V2. There were some differences, which I wrote about here and here. V2 is no longer the current chip.

Except for 23andMe who wants their customers to purchase their most current test, the other companies no longer routinely announce new chip versions. They just go about their business. The only way you know that a vendor actually changed something is when the other companies who accept uploads suddenly encounter an issue with file formats. It always takes a few weeks to sort that out.

My Ancestry V1 test’s ethnicity results don’t show my Native American ethnicity.

Ancestry results were updated in June 2022

However, my V2 results do include Native American ethnicity.

Matches at Ancestry

I have many more matches on my V1 test at Ancestry because I took steps to preserve my smaller matches when Ancestry initiated its massive purge in 2020. I wrote about that here and here.

Ancestry’s SideView breaks matches down into maternal, paternal, and unassigned based on your side selection. You tell Ancestry which side is which. You may be able to determine which “side” is maternal or paternal either by your ethnicity or shared matches. While SideView is not always accurate, it’s a good place to begin.

Match Category	Ancestry V1 Test	Ancestry V2 Test
Maternal	15,587	15,116
Paternal	42,247	41,870
Both	2	2
Unassigned	48,999	4,127
Total	106,835	61,115

Ancestry either displays all your matches or your matches by side, which I used to compile the table above. I suspect that Ancestry is not assigning any of the smaller preserved matches to “sides” based on the numbers above.

Ancestry implemented a process called Timber that removes DNA that they feel is “too matchy,” meaning you match enough people in this region that they think it’s a pileup region for you personally, and therefore not useful. In some cases, enough DNA is removed causing that person to no longer be considered a match because they fall beneath the match threshold. I am not a fan of Timber.

Your match amount shown is AFTER Timber has removed those segments. Unweighted shared DNA is your pre-Timber match amount.

You can view the Unweighted shared DNA by clicking on the amount of shared DNA on your match list.

You can read Ancestry’s Matching White Paper, here.

Let’s take a look at my matches. I’ve listed both weighted and unweighted where they are different.

Match	Ancestry V1	Ancestry V2
Michael	755 cM, 35 seg	737 cM, 33 seg
Edward	66 cM, 4 seg (unweighted 86 cM)	65 cM, 4 seg (unweighted 86 cM)
Tom	59 cM, 3 seg (unweighted 63)	Same
Jonathon	43 cM, 4 seg, (unweighted 52 cM)	Same
Matthew	20 cM, 2 seg (unweighted 35 cM)	Same

Harold	132 cM, 7 seg	135 cM, 6 seg
Dean	67 cM, 4 seg (unweighted 78 cM)	66 cM, 4 seg (unweighted 78 cM)
Debbie	93 cM, 5 seg	Same
Valli	142 cM, 3 seg	Same
Jared	20 cM, 1 seg (unweighted 22 cM)	Same

Timber only removes DNA when the match is under 90 cM. Almost every match under 90 cM has some DNA removed.

Ancestry Summary

The results of the two Ancestry tests are very close.

In some circumstances, no DNA is removed by Timber, so the unweighted is the same as the weighted. However, in other cases, a significant amount is removed. 15 cM of Matthew’s 35 cM was removed by Timber, reducing his total to 20 cM.

Remember that Ancestry does not show shared matches unless they are greater than 20 cM, which is different than any other DNA testing company.

At one point, Ancestry was selling a health test that was also a genealogy test. That test utilized a different chip that is not accepted for uploads by other vendors. The results of that test might well be different that the “normal” Ancestry tests focused on genealogy. The Ancestry health test is no longer offered.

Companies that Accept Uploads

DNA testing companies that accept uploaded DNA files from other DNA testing companies need to process the uploaded file, just like a file that is generated in their own lab. Of course, they must deal with the differences between uploaded files and their own file format. The processing includes imputation and formulates the uploaded file so that it works with the tools that they provide for their customers, including ethnicity (by whatever name they use) matching, family matching (bucketing), advanced matching, the match matrix, triangulation, AutoClusters, Theories of Family Relativity, and other advanced tools.

Of course, the testing company accepting uploads can only work with the DNA locations provided by the original DNA testing company in the uploaded file.

Matching and some additional tools are free to uploaders, but advanced tools require an inexpensive unlock.

FamilyTreeDNA

I took a test at FamilyTreeDNA, plus uploaded a copy of both of my Ancestry DNA files.

FamilyTreeDNA named their population (ethnicity) test myOrigins and the current version is V3. I wrote about the rollout and comparison in September of 2020, here.

My DNA test taken at FamilyTreeDNA, above, reveals Native American segments that match reference populations found both in North and South America and the Caribbean Islands.

At FamilyTreeDNA, my Ancestry V1 uploaded file results show Native American population matches only in North America.

Interestingly, my Ancestry V1 file processed AT Ancestry did not reveal Native American ancestry, but the same file uploaded to and processed at FamilyTreeDNA did show Native American results, reflecting the difference between the vendors’ internal algorithms and reference populations utilized.

My myOrigins results from my Ancestry V2 uploaded file at FamilyTreeDNA also include my North American Native American segments. The V2 test also showed Native American ethnicity at Ancestry, so clearly something changed in Ancestry’s algorithm, locations tested, and/or reference populations between V1 and V2.

Fortunately, FamilyTreeDNA provides both chromosome painting and a population download file so I can match those Native segments with my autosomal matches to identify which of my ancestors contributed those specific segments.

One of my Native segments is shown in pink on Chromosome1. My mother has a Native segment in exactly the same location, so I know that this segment originated with my mother’s ancestors.

I downloaded the myOrigins population segment file and painted my results at DNAPainter, along with the matches where I can identify our common ancestor. This allowed me to pinpoint the ancestral line that contributed this Native segment in my maternal line. You can read about using DNAPainter, here.

FamilyTreeDNA Matches

I have significantly more matches at FamilyTreeDNA on their test than on either of my Ancestry tests that I uploaded. However, nearly the same number are maternally or paternally assigned through Family Matching, with the remainder unassigned. You can read about Family Matching here.

Match Category	FamilyTreeDNA Test	Ancestry V1 at FamilyTreeDNA	Ancestry V2 at FamilyTreeDNA
Paternal	3,479	3,572	3,422
Maternal	1,549	1,536	1,477
Both	3	3	3
All	8,154	6,397	6,579

Family matching, aka bucketing, automatically assigns my matches as maternal and paternal by linking known relatives to their place in my tree.

I completed the following match chart using my original test taken at FamilyTreeDNA, plus the same match at FamilyTreeDNA for both of my Ancestry tests.

In other words, Cheryl matched me at 467 cM on 21 segments on the original test taken at FamilyTreeDNA. She matched me on 473 cM and 21 segments on my Ancestry V1 test uploaded to FamilyTreeDNA and on 483 cM and 22 segments on the Ancestry V2 test uploaded to FamilyTreeDNA.

Match	FamilyTreeDNA	Ancestry V1 at FTDNA	Ancestry V2 at FTDNA
Cheryl	467 cM, 21 seg	473 cM, 21 seg	483 cM, 22 seg
Patricia	195 cM, 11 seg	189 cM, 11 seg	188 cM, 11 seg
Tom	77 cM, 4 seg	71 cM, 4 seg	76 cM, 4 seg
Thomas	72 cM, 3 seg	71 cM, 3 seg	74 cM, 3 seg

Harold	127 cM, 5 cM	133 cM, 6 seg	143 cM, 6 seg
Dean	81 cM, 4 seg	75 cM, 3 seg	83 cM, 4 seg
Carl	103 cM, 4 seg	101 cM, 4 seg	102 cM, 4 seg
Debbie	99 cM, 5 seg	97 cM, 5 seg	99 cM, 5 seg
David	373 cM, 16 seg	435 cM, 19 seg	417 cM, 18 seg
Amos	176 cM, 7 seg	177 cM. 8 seg	177 cM, 7 seg
Buster	387 cM, 15 seg	396 cM, 16 seg	402 cM, 17 seg
Charlene	461 cM, 21 seg	450 cM, 21 seg	448 cM, 20 seg
Carol	65 cM, 6 seg	64 cM, 6 seg	65 cM, 6 seg

I have tested many of my cousins at FamilyTreeDNA and encouraged others to test or upload. I’ve attempted to include enough people so that I can have common matches at least at one other DNA testing company for comparison.

FamilyTreeDNA Summary

The matches are relatively close, with a few being exact.

Interestingly, some of the segment counts are different. In most cases, this results from one segment being broken into multiple segments by one or more of the tests, but not always. In the couple that I checked, the entire segment seems to descend from the same ancestral couple, so the break is likely a result of not all of the same DNA locations being tested, plus the limits of imputation.

MyHeritage

I have two tests at MyHeritage. One taken at MyHeritage, and an uploaded file from FamilyTreeDNA.

MyHeritage displays both ethnicity results and Genetic Groups which maps groups of people that you match. I left the Genetic Groups setting at the highest confidence level. Shifting it to lower displays additional Genetic Groups, some of which overlap with or are within ethnicity regions.

My test taken at MyHeritage, above, shows several ethnicities and Genetic Groups, but no Native American.

My FamilyTreeDNA kit processed at MyHeritage shows the same ethnicity regions, one additional Genetic Group, plus Native American heritage in the Amazon which is rather surprising given that I don’t show Native in North American regions where I’m positive my Native ancestors lived.

MyHeritage Matching

At MyHeritage, I compared the results of the test I took with MyHeritage, and a test I uploaded from FamilyTreeDNA. Fewer than half of my matches can be assigned to a parent via shared matching.

Matches	MyHeritage Test	FamilyTreeDNA at MyHeritage
Paternal	4,422	6,501
Maternal	2,660	3,655
Total	13,233	16,147

I have rounded my matches at MyHeritage to the closest cM.

Match	MyHeritage Test	FamilyTreeDNA at MyHeritage
Michael	801 cM, 32 seg	823 cM, 31 segments
Cheryl	467 cM, 23 seg	477 cM, 23 seg
Roland	No match	28 cM, 1 seg
Patty	156 cM, 9 seg	151 cM, 9 seg
Rex	43 cM, 4 seg	53 cM, 3 seg
Don	369 cM, 16 seg	382 cM, 17 seg

David	449 cM, 17 seg	460 cM, 17 seg
Charlene	454 cM, 23 seg	477 cM, 24 seg
Buster	408 cM, 15 seg	410 cM, 16 seg
Amos	183 cM, 8 seg	Same
Carol	78 cM, 6 seg	87 cM, 7 seg

MyHeritage Summary

I was surprised to discover that Roland had no match with the MyHeritage test, but did with the FamilyTreeDNA test. I wonder if this is a searching or matching glitch, especially since both companies use the same chip. 28 cM in one segment is a reasonably large match, and even if it was divided in two, it would still be over the matching threshold. I know this is a valid match because Roland triangulates with me and several cousins, I’m positive of our common ancestor, and he also matches me at both FamilyTreeDNA and 23andMe.

Other than that, the matches are reasonably close, with one being exact.

Your Matches Aren’t Everyplace

I unsuccessfully searched for someone who was a match to me in all four databases. Ancestry does not permit match downloads, so I had to search manually. People don’t always use the same names in different databases.

Surprisingly, I was unable to find one match who is in all of the databases. Many people only suggest testing at Ancestry because they have the largest database, but if you look at the following comparison chart that I’ve created, you’ll see that 16 of 26 people, or 62% were not at Ancestry. Conversely, many people were at Ancestry and not elsewhere. I could not find five maternal and five paternal matches at Ancestry that I could identify as matches in another database. 40% were not elsewhere.

If you think for one minute that it doesn’t matter for genealogy if you’re in all four major databases, please reconsider. It surely does matter.

Every single vendor has matches that the others don’t. Substantial, important matches. I have found first and second-cousin matches in every database that weren’t elsewhere.

Many of the original testers have passed away and can’t test again. My mother can never test at either 23andMe or Ancestry, but she is at both FamilyTreeDNA and MyHeritage because I could upgrade her kit at FamilyTreeDNA after she died. I uploaded her to MyHeritage. Of course, because she is a generation closer to our ancestors, she has many valuable matches that I don’t.

Each vendor provides either an email address or a messaging platform for you to contact your matches. Don’t be discouraged if they don’t answer. Just today, I received a reply that was years in the making.

Genealogists hope for immediate gratification, but we are actually in this for the long game. Play it with every tool at your disposal.

The Answer

Does it matter if you test at a DNA testing company, or upload a file?

I know this was a very long answer to what my readers hoped was a simple yes or no question.

There is no consistent answer at either FamilyTreeDNA or MyHeritage, the two DNA testing companies that accept uploads. Be sure you’re in both databases. My closest two matches that I did not test were found at MyHeritage. Here’s a direct link to upload at MyHeritage.

Of the vendors, those two should be the closest to each other because they are both processed in the GenebyGene lab, but again, the actual chip version, when the test was originally taken, and each vendor’s internal processing will result in differences. Neither the original test at the DNA testing company nor the uploaded files have consistently higher or lower matches. Neither type of test or upload appears to be universally more or less accurate. Differences in either direction seem to occur on a match-by-match basis. Many are so close as to be virtually equivalent, with a few seemingly random exceptions. Of course, we always have to consider Timber.

If you upload, unlock the advanced features at both FamilyTreeDNA and MyHeritage.

If you upload to a DNA testing company, you may discover in the future that some features and functions will only be available to original testers.

Personally, if I had the option, I would test at the company directly simply because it eliminates or at least reduces the possibility of future incompatibilities – with the exception of 23andMe which has chosen to not provide consistent updates to older tests. I’m incredibly grateful I didn’t test my mother or now deceased family members at 23andMe, and only there. I would be heartsick, heartbroken, and furious.

Our DNA is an extremely valuable resource for our genealogy. It’s the gift that truly keeps on giving, day after day, even when other records don’t exist. Be sure you and your family members are in each database one way or another, and test your Y-DNA (for males) and mitochondrial DNA (for everyone) to have a complete arsenal at your disposal.

What Is a Sibling Anyway? Full, Half, Three-Quarters, Step, Adopted, Donor-Conceived & Twins

Posted on April 26, 2023 by Roberta Estes

I’ve seen the term sibling used many different ways, sometimes incorrectly.

When referring to their own siblings, people usually use the term brother or sister, regardless of whether they are talking about a full, half or step-sibling. It’s a term of heart or description. It’s often genealogists who are focused on which type of sibling. As far as I’m concerned, my brother is my brother, regardless of which type of brother. But in terms of genetics, and genealogy, there’s a huge difference. How we feel about our sibling(s) and how we are biologically related are two different things.

Let’s cover the various types of siblingship and how to determine which type is which.

Full Siblings – Share both parents
Half-Siblings – Share only one parent
Three-Quarter Siblings – It’s complicated
Adopted Siblings
Donor-Conceived
Step-Siblings – Share no biological parent
Twins – Fraternal and Identical

Full Siblings

Full siblings share both parents and share approximately 50% of their DNA with each other.

You can tell if you are full siblings with a match in various ways.

You share the same fairly close matches on both parents’ sides. For example, aunts or uncles or their descendants.

Why do I say close matches? You could share one parent and another more distant relative on the other parent’s side. Matching with close relatives like aunts, uncles or first cousins at the appropriate level is an excellent indicator unless your parents or grandparents are available for testing. If you are comparing to grandparents, be sure to confirm matches to BOTH grandparents on each side.

Full siblings will share in the ballpark of 2600 cM, according to DNAPainter’s Shared cM Tool.

Keep in mind that you can share more or less DNA, hence the range. It’s also worth noting that some people who reported themselves as full siblings in the Shared cM project were probably half siblings and didn’t realize it.

Full siblings will share a significant amount of fully identical regions (FIR) of DNA with each other, meaning they share DNA at the same DNA address from both parents, as illustrated above. Shared DNA with each other inherited from Mom and Dad are blocked in green. The fully identical regions, shared with both parents, are bracketed in purple. You can’t make this determination at FamilyTreeDNA, MyHeritage or Ancestry, but you can at both 23andMe and GEDmatch.

At GEDmatch, the large fully green areas in the chromosome browser “graphics and positions” display indicates full siblings, where DNA is shared from both parents at that location.

I wrote about the details of how to view fully identical regions (FIR) versus half identical regions (HIR) in the article, DNA: In Search of…Full and Half-Siblings.

If your parents/grandparents have tested, you and your full sibling will both match both parents/grandparents. Yes, I know this sounds intuitive, but sometimes it’s easy to miss the obvious.

At FamilyTreeDNA, you can use the matrix tool to see who matches each other in a group of people that you can select. In this case, both siblings are compared to the father, but if the father isn’t available, a close paternal relative could substitute. Remember that all people who are 2^nd cousins or closer will match.

At Ancestry, full siblings will be identified as either “brother” or “sister,” while half-siblings do not indicate siblingship. Half-siblings are called “close family” and a range of possible relationships is given. Yes, Ancestry, is looking under the hood at FIR/HIR regions. I have never seen a full sibling misidentified as anything else at Ancestry. Unfortunately, Ancestry does not give customers access to their matching chromosome segment location data.
Y-DNA of males who are full siblings will match but may have some slight differences. Y-DNA alone cannot prove a specific relationship, with very rare exceptions, but can easily disprove a relationship if two males do not match. Y-DNA should be used in conjunction with autosomal DNA for specific relationship prediction when Y-DNA matches.
Y-DNA testing is available only through FamilyTreeDNA, but high-level haplogroup-only estimates are available through 23andMe. Widely divergent haplogroups, such as E versus R, can be considered a confirmed non-match. Different haplogroups within the same base haplogroup, such as R, but obtained from different vendors or different testing levels may still be a match if they test at the Big Y-700 level at FamilyTreeDNA.
Mitochondrial DNA, inherited matrilineally from the mother, will match for full siblings (barring unusual mutations such as heteroplasmies) but cannot be used in relationship verification other than to confirm nonmatches. For both Y-DNA and mitochondrial DNA, it’s possible to have a lineage match that is not the result of a direct parental relationship.
Mitochondrial DNA testing is available only through FamilyTreeDNA, but haplogroup-only estimates are included at 23andMe. Different base haplogroups such as H and J can be considered a non-match.
A difference in ethnicity is NOT a reliable indicator of half versus full siblings.

Half-Siblings

Half-siblings share only one parent, but not both, and usually share about 25% of their DNA with each other.

You will share as much DNA with a half-sibling as you do some other close matches, so it’s not always possible for DNA testing companies to determine the exact relationship.

Referencing the MyHeritage cM Explainer tool, you can see that people who share 1700 cM of DNA could be related in several ways. I wrote about using the cM Explainer tool here.

Hints that you are only half-siblings include:

At testing vendors, including Ancestry, a half-sibling will not be identified as a sibling but as another type of close match.
If your parents or grandparents have tested, you will only match one parent or one set of grandparents or their descendants.
You will not have shared matches on one parent’s side. If you know that specific, close relatives have tested on one parent’s side, and you don’t match them, but your other family members do, that’s a very big hint. Please note that you need more than one reference point, because it’s always possible that the other person has an unknown parentage situation.
At 23andMe, you will not show fully identical regions (FIR).
At GEDmatch, you will show only very minimal FIR.

Scattered, very small green FIR locations are normal based on random recombination. Long runs of green indicate that significant amounts of DNA was inherited from both parents. The example above is from half-siblings.

At FamilyTreeDNA and 23andMe, most men who share a mother will also share an X chromosome match since men only inherit their X chromosome from their mother. However, it is possible for the mother to give one son her entire X chromosome from her father, and give the other son her entire X chromosome from her mother. Therefore, two men who do share a mother but don’t have an X chromosome match could still be siblings. The X is not an entirely reliable relationship predictor. However, if two men share an entire X chromosome match, it’s very likely that they are siblings on their mother’s side, or that their mothers are very close relatives.

Three-Quarter Siblings

This gets a little more complicated.

Three-quarter siblings occur when one parent is the same, and the other parents are siblings to each other.

Let’s use a real-life example.

A couple marries and has children. The mother dies, and the father marries the mother’s sister and has additional children. Those children are actually less than full siblings, but more than half-siblings.

Conversely, a woman has children by two brothers and those children are three-quarter siblings.

These were common situations in earlier times when a man needed a female companion to raise children and women needed a male companion to work on the farm. Neither one could perform both childcare and the chores necessary to earn a living in an agricultural society, and your deceased spouse’s family members were already people you knew. They already loved your children too.

Neither of these situations is historically unusual, but both are very difficult to determine using genetics alone, even in the current generation.

Neither X-DNA nor mitochondrial DNA will be helpful, and Y-DNA will generally not be either.

Unfortunately, three-quarter siblings’ autosomal DNA will fall in the range of both half and full siblings, although not at the bottom of the half-sibling range, nor at the top of the full sibling range – but that leaves a lot of middle ground.

I’ve found it almost impossible to prove this scenario without prior knowledge, and equally as impossible to determine which of multiple brothers is the father unless there is a very strong half-sibling match in addition.

The DNA-Sci blog discusses this phenomenon, but I can’t utilize comparison screenshots according to their terms of service.

Clearly, what we need are more known three-quarter siblings to submit data to be studied in order to (possibly) facilitate easier determination, probably based on the percentage frequency distribution of FIR/HIR segments. Regardless, it’s never going to be 100% without secondary genealogical information.

Three-quarter siblings aren’t very common today, but they do exist. If you suspect something of this nature, really need the answer, and have exhausted all other possibilities, I recommend engaging a very experienced genetic genealogist with experience in this type of situation. However, given the random nature of recombination in humans, we may never be able to confirm using any methodology, with one possible exception.

There’s one possibility using Y-DNA if the parents in question are two brothers. If one brother has a Y-DNA SNP mutation that the other does not have, and this can be verified by testing either the brothers who are father candidates or their other known sons via the Big Y-700 test – the father of the siblings could then be identified by this SNP mutation as well. Yes, it’s a long shot.

Three-quarter sibling situations are very challenging.

Step-siblings, on the other hand, are easy.

Step-Siblings

Step-siblings don’t share either parent, so their DNA will not match to each other unless their parents are somehow related to each other. Please note that this means either of their parents, not just the parents who marry each other.

One child’s parent marries the other child’s parent, resulting in a blended family. The children then become step-siblings to each other.

The terms step-sibling and half-sibling are often used interchangeably, and they are definitely NOT the same.

Adopted Siblings

Adopted siblings may not know they are adopted and believe, until DNA testing, that they are biological siblings.

Sometimes adopted siblings are either half-siblings or are otherwise related to each other but may not be related to either of their adoptive parents. Conversely, adopted siblings, one or both, may be related to one of their adoptive parents.

The same full and half-sibling relationship genetic clues apply to adopted siblings, as well as the tools and techniques in the In Search of Unknown Family series of articles.

Donor-Conceived Siblings

Donor-conceived siblings could be:

Half-siblings if the donor is the same father but a different mother.
Half-siblings if they share an egg donor but not a father.
Full siblings if they are full biological siblings to each other, meaning both donors are the same but not related to the woman into whom the fertilized egg was implanted, nor to her partner, their legal parents.
Not biologically related to each other or either legal parent.
Biologically related to one or both legal parents when a family member is either an egg or sperm donor.

Did I cover all of the possible scenarios? The essence is that we literally know nothing and should assume nothing.

I have known of situations where the brother (or brothers) of the father was the sperm donor, so the resulting child or children appear to be full or three-quarters siblings to each other. They are related to their legal father who is the mother’s partner. In other words, in this situation, the mother’s husband was infertile, and his brother(s) donated sperm resulting in multiple births. The children from this family who were conceived through different brothers and had very close (half-sibling) matches to their “uncles'” children were very confused until they spoke with their parents about their DNA results.

The same techniques to ascertain relationships would be used with donor-conceived situations. Additionally, if it appears that a biological relationship exists, but it’s not a full or half-sibling relationship, I recommend utilizing other techniques described in the In Search of Unknown Family series.

Twins or Multiple Birth Siblings

Two types of twin or multiple birth scenarios exist outside of assisted fertilization.

Fraternal twins – With fraternal or dizygotic twins, two eggs are fertilized independently by separate sperm. Just view this as one pregnancy with two siblings occupying the same space for the same 9 months of gestation. Fraternal twins can be male, female or one of each sex.

Fraternal twins are simply siblings that happen to gestate together and will match in the same way that full siblings match.

Please note that it’s possible for two of a woman’s eggs to be fertilized at different times during the same ovulation cycle, potentially by different men, resulting in twins who are actually half-siblings.

A difference in ethnicity is NOT a reliable indicator of fraternal or identical twins. Submitting your own DNA twice often results in slightly different ethnicity results.

Identical twins – Identical or monozygotic twins occur when one egg is fertilized by one sperm and then divides into multiple embryos that develop into different children. Those children are genetically identical since they were both developed from the same egg and sperm.

Two of the most famous identical twins are astronauts Mark and Scott Kelly.

Identical twins are the same sex and will look the same because they have the same DNA, except for epigenetic changes, but of course external factors such as haircuts, clothes and weight can make identical twins physically distinguishable from each other.

DNA testing companies will either identify identical twins as “self,” “identical twin” or “parent/child” due to the highest possible shared cM count plus fully matching FIR regions.

For identical twins, checking the FIR versus HIR is a positive identification as indicated above at GEDmatch with completely solid green FIR regions. Do not assume twins that look alike are identical twins.

Siblings

Whoever thought there would be so many kinds of siblings!

If you observe the need to educate about either sibling terminology or DNA identification methodologies, feel free to share this article. When identifying relationships, never assume anything, and verify everything through multiple avenues.

So, You Want to Become a Professional Genetic Genealogist

Posted on April 18, 2023 by Roberta Estes

I get asked quite often about what is required to become a professional genetic genealogist.

That’s actually two separate questions.

What is required to become a professional genealogist?
Then, what is required to specialize as a genetic genealogist?

What It’s Not

Before we have this discussion, I need to make sure that you understand that I’m NOT talking about forensics, meaning IGG, or investigative genetic genealogy in this article.

This is NOT forensics (IGG)
This is also not a specialty in finding missing parents for adoptees and others searching for unknown parents.

Both IGG and adoption searches utilize the same methodology, a subset of genetic genealogy. I wrote about that in Identifying Unknown Parents and Individuals Using DNA Matching.

The difference between genetic genealogy more broadly and IGG is:

What you’re searching for
The perspective
The methods utilized.

Essentially, the functional difference is that genealogists know who they are and have some information about their ancestors. For example, they know who their parents are and probably at least their grandparents. Genealogists are using both DNA testing and traditional genealogical paper trail research methods to focus and make discoveries going backwards in time.

Both IGG and unknown parent research uses DNA and (sometimes some) paper trail genealogy to find ways to connect the closest matches to the DNA tester (or DNA sample) together to each other to identify either living or recently living people. For example, two people who are are first cousins to the tester should both have the same grandparents if they are related to the tester through the same parent.

If two people who are related to the tester as first cousins do not share the same grandparent(s), then they are related to the tester through different parents of the tester.

The commonality is that DNA testing and some types of records are used for:

IGG where you’re searching for the identity of the tester or DNA sample
Unknown parent(s) searches where you are searching for the identity of the parent(s)
Genetic genealogy

However, the search methodology is different for IGG and unknown parents than for genealogy.

With IGG and unknown parent searches, you’re looking for your closest matches, then attempting to connect them together to identify either currently living or recently living people.

This article focuses specifically on genealogy and genetic genealogy, meaning looking backwards in time to identify ancestors.

I wrote about the techniques used for both IGG and parental searching in the article, Identifying Unknown Parents and Individuals Using DNA Matching.

What Do Genealogists Do?

Genealogy is the study of family history and the descent of a person or a family. Genealogists use a variety of sources and methods to discover and show the ancestry of their subjects and in doing so, create the family trees that are familiar to all of us.

Genealogists use different sources and methods to find and show the descent and kinship of their subjects.

Traditional sources include but are not limited to the following record types:

Vital records (birth, marriage, and death certificates)
Census
Military
Immigration
Land and tax records
Wills and probate
Church records
Newspapers
Obituaries
Published and online books
Oral histories
Genealogy databases
And more

Of course, today the four types of DNA can be added to that list.

A professional genealogist needs to know how and where to find these types of records in the target area, any unique cultural or regional factors affecting those records, and how to interpret them both individually and together.

For example, in a deed record in colonial Virginia, why would, or wouldn’t a female release her dower right? What is dower right, and why is it important? How might that record, or lack thereof, affect future probate for that woman/couple? In what type of historical or court record book might one look for these types of records?

Genealogists also need to know how to weigh different types of information in terms of potential accuracy and how to interpret primary and secondary sources.

Primary sources are those that were created at or near the time of an event by someone who was present at the event or who had first-hand knowledge of it. Examples of primary sources include birth certificates, marriage licenses, and census records, although census records are far more likely to be inaccurate or incomplete than a birth certificate or marriage record. Genealogists need to understand why, and where to look for corroboration. Primary sources are considered to be most accurate.

Secondary sources are those that were created later by someone who did not have first-hand knowledge of the event. Examples of secondary sources include family histories and genealogies, published biographies, and sometimes, newspaper articles.

The genealogists “go to” source for understanding and interpreting evidence is Evidence Explained by Elizabeth Shown Mills, available here.

Of course, DNA understanding and analysis needs to be added to this list and has become an important resource in genealogy. Additionally, genetic genealogy has become a specialty within the broader field of genealogy, as has IGG.

Put another way, a genealogist should have expertise and a specialty in some area. Maybe Italian records, or Native American genealogy, or New England records, in addition to the basic skills. At one time, a genealogist didn’t necessarily HAVE TO have expertise in genetic genealogy as well, but that has changed in the past few years. A professional genealogist should MINIMALLY understand the basics of genetic genealogy and when/how it can be useful. They may or may not have ready access to a genetic genealogist within the company where they work.

Being an independent genealogist, unless you specialize only in a specific area, like Dutch genealogy, is much more challenging because you’ll need to be proficient in BOTH Dutch genealogy AND genetic genealogy. It’s tough keeping up with one specialty, let alone two, although in this case, Yvette does an amazing job. However, her primary specialty is Dutch genealogy, and genetic genealogy is the booster rocket when appropriate. Genetic genealogy is not always needed for traditional genealogy, which is why genetic genealogy is a specialty skill.

In addition to all that, you also need to be proficient and comfortable with technology and a good communicator. Walking on water is also helpful:)

Job Description

So, what does the job description for a genealogist look like?

I reached out to Legacy Tree Genealogists because they are one of the largest, if not the largest genealogy research company, and they partner with 23andMe, FamilyTreeDNA, and MyHeritage. Legacy Tree has specialists in many regions and languages, in addition to six genetic genealogists on staff.

Fortunately, they have a job listing posted right now, here, with an excellent description of what is expected.

If you’re interested or wish to sign up for notifications, click here.

Understanding that this job description won’t be posted forever, I reached out to the owner, Jessica Dalley Taylor, and asked if she would send me a sample description to include in this article.

Here you go, courtesy of Jessica:

About You

It’s not easy to make each client’s experience the very best it can possibly be, and it means we can only hire an exceptional genealogist for this position. You will be a great fit if:

- You are fluent in English and can explain your genealogy discoveries in a way that clients connect with and understand
- You have taken at least one genetic genealogy test or administered the test of a relative

Please note that Legacy Tree offers both traditional genealogy services, combined with genetic genealogy, along with adoption and unknown parent searches.

As a measure of fundamental basic genetic genealogy skills, you should be able to create and teach a class like First Steps When Your DNA Results Are Ready – Sticking Your Toe in the Genealogy Water.

You should also be able to read and fully comprehend the articles on this blog, as well as explain the content to others. A very wise person once told me that if you can’t explain or teach a topic, you don’t understand it.

As luck would have it, Ancestry also posted a job opening for a genealogist as I was finishing this article. Here’s part of the job requirements.

Contractor or Employee

Please note that many companies have shifted their primary hiring strategy to utilizing contractors for not more than half time, especially now that working remotely has become the norm.

This may or may not be good news for you.

It allows the company to avoid paying benefits like insurance, vacation, leave, and retirement programs which reduces their costs. You may not need these benefits, and it may represent an opportunity for you. For others who need those benefits, it’s a deal-breaker.

Contracting may provide the ability to work part-time, but contracting probably means you need to have business management skills not required when you work for someone else. Let’s just say that I make quarterly estimated tax payments and my annual CPA bill is in the $2,000 range.

Compensation

Pay, either as an employee or contractor for a company, is a sticky wicket in this field.

First, there’s a consumer mindset, although not universal, that genealogy “should be” free. In part, this is due to search angels and a history of well-intentioned people making things free. I’m one of them – guilty as charged – this blog is free. My hourly work, however, when I accepted clients (which I DO NOT now,) was not free.

However, that “should be free” mindset makes it difficult to shift to a “pay to play” mentality when people can go on social media and get what they want for free.

Professional services are not and should not be free.

Professionals should be able to earn a respectable living. The full-time Ancestry job, posted above, with those credentials, nets out to $21.63 per hour for a 40-hour week, with a graduate degree preferred. For comparison, google other jobs and professions.

If you doubt for one second whether professional services should or should not be free, especially ones that require a bachelor’s degree or master’s, just think about what your CPA would do if you asked them to do your taxes because they have the ability, for free. Same for a doctor, lawyer, or any other professional.

People are often shocked at the rates paid to employees versus the rates charged to prospective customers. This discussion has recently gotten spicy on social media, so I’m not going to comment other than to say that when I did take private clients, which I DO NOT ANYMORE, I found it much more beneficial to operate independently than to work for a company.

However, I also had a readily recognizable specialty and an avenue to reach potential clients.

I also already had a business structure set up, and a CPA, and perhaps more important than either of those – I had medical insurance already in place.

The need for benefits is what drives many people to work for companies, which I fully understand. It’s also a big factor in why there are more female genealogists than male genealogists. Married women in the US are eligible to be covered by their spouse’s insurance, assuming the spouse has insurance through their employer.

My very strong recommendation to you is to weigh all of the factors and NEVER to find yourself without medical insurance or coverage.

If you’re going to be “self-employed,” set up a company. If you’re going to set up a company, do it properly, understand the tax ramifications of the various types of corporations and engage a competent CPA to shepherd you through the process from day 1 through taxes. They are worth every penny.

Look at various jobs in the market, review at the associated pay, get a quote for genealogy services of the type you would be providing from the various companies – and decide if this profession is really for you.

I don’t mean to be a wet blanket, just a realist.

Training and Certification

Now for the good news and the bad news.

There is professional training for genealogy
There are certifications for genealogy
There is no “one place” for either
There is no certification for genetic genealogy
There’s a LOT of misunderstanding and misinformation about genetic genealogy
Genetic genealogy changes often

You need to view your education for genealogy/genetic genealogy in the same way you’d view obtaining a college degree – plus continuing education to maintain your education and skills at a current and functional level.

And yes, all of that costs money. If you decide to work for a company, be sure to ask if continuing ed is on their dime and time, or yours.

Genealogy Training

The Board for Certification of Genealogists, BCG, allows graduates to append CG, for Certified Genealogist after their name. BCG is focused on certification of skills and is not a training platform, although they do provide some webinars, etc. It’s not a college curriculum though. Certification is the “end game” for many. Candidates must submit a portfolio for evaluation, complete in a specific timeframe, and must reapply every five years to maintain their certification.

Not all genealogists are certified by BCG, and BCG only lists references of BCG members.

In the field of Genetic Genealogy, that can be problematic because many competent and well-known people are not BCG certified. BCG does not have a genetic genealogy certification.

Lack of BCG certification does not mean that someone is not qualified, and BCG certification certainly does NOT mean or imply that the individual is competent in genetic genealogy, which has more and more become a part of almost every genealogical puzzle. If not for initial discovery, for confirmation.

There are many avenues for genealogical training, including, but not limited to:

Brigham Young University Family History Degree
NGS Home Study Course
Salt Lake Institute of Genealogy (SLIG)
Genealogical Research Institute of Pittsburgh (GRIP)
Boston University Certificate program
Genealogical Institute on Federal Records (Gen-Fed)
Institute of Genealogy and Historical Research (IGHR)
University of Strathclyde
University of Dundee
Major Conferences, including RootsTech and NGS, among others
Specialty conferences such as the International Conference on Jewish Genealogy (IAJGS)
Online conferences and conference proceedings such as Rootstech who maintains a free library of their virtual and recorded conference sessions.
Legacy Family Tree Webinars
Videos produced by major genealogy companies such as MyHeritage, FamilyTreeDNA and Ancestry, often available through their website, Youtube or both
Blogs and learning/help centers of the major genealogy companies
- MyHeritage blog
- Ancestry blog

Genetic Genealogy Training

Genetic genealogy training is more challenging because there is no specific program, curriculum, or certification.

Many genetic genealogists obtained their experience as a part of genealogy over 15 or 20 years and have focused on the genetic aspect of genealogy. Several of us had a scientific background that meshed well with this field and is part of why we discovered that our passion is here.

Before I provide this resource list, I need to emphatically state that probably 95% of answers that I see provided on social media platforms in response to questions asked by people are either entirely incorrect, partially incorrect in a way that makes me want to say, “well, not exactly,” or are incomplete in a way that makes a significant difference.

I chose and choose to focus on creating educational tools and making explanations available for everyone, in one place, not one question at a time.

I began publishing my blog in 2012 as an educational tool and I’m dumbstruck by how many people just want a yes or no answer instead of learning. If one doesn’t take the time to learn, they have no idea if the answers they receive are valid, or if there’s more to the story that they are missing.

Social media can mislead you badly if you don’t have the ability to discern between accurate answers, partially accurate answers, and incorrect answers. Furthermore, opinions differ widely on some topics.

Unfortunately, because there is no genetic genealogy credentialling, there is also no “post-nominal letters,” such as CG for certified genealogist. Therefore, a novice has absolutely no idea how to discern between an expert and another overly helpful novice who is unintentionally providing incorrect or partial information.

Many of us who at one time reliably answered questions have simply gotten burned out at the same question being asked over and over, and no longer regularly engage. Burnout is real. Another issue is that askers often don’t provide enough, or accurate, information, so a significant amount of time is spent in clarifying the information around a question. Furthermore, your CPA, lawyer, and physician don’t answer questions online for free, and neither do most people who are busy earning a living in this field.

DNA educational opportunities, some of which are contained within larger conference agendas, include:

This blog, DNAexplain, of course, with more than 1600 articles
RootsTech has an entire DNA tract, including online sessions
East Coast Genetic Genealogy Conference (Oct 6-8, 2023)
I4GG is now focused on IGG specifically
Diahan Southard’s DNA Academy and blog
Jim Bartlett’s Segmentology blog
ISOGG – International Society of Genetic Genealogy pages and Facebook group. As with any volunteer endeavor, it’s difficult to find people to update and maintain things, so much of this information is not up to date.
DNA Adoption classes
DNAPainter, blog and Facebook group
Genetic Affairs and Facebook group
DNAGedcom.com and Facebook user group
Portions of some Institutes as noted in the genealogy section
Legacy Family Tree Webinars DNA category
Blogs, videos and help centers of the vendors: FamilyTreeDNA, MyHeritage, Ancestry, 23andMe.

There are other blogs, of course, some of which were launched by well-known genetic genealogists but are no longer maintained. Blogging is quite time-consuming.

I’ve covered all kinds of genetic genealogy topics in my blog articles. They are a good source of information, education and hands-on training. I attempt to publish two articles weekly, and there are over 1600 available for your enjoyment.

In addition to the initial learning period, you’ll need to make time to stay engaged and maintain your genealogy and genetic genealogy skills.

Apprenticeship

In addition to training, I think you’d need at least a year interning or working at a junior learning level, minimum. Think of it as your genealogy residency.

You could choose to work for a vendor in their help center.
You could choose to work for a genealogy company. I’ve mentioned the largest ones, but there are others as well.
You could choose to work on your own case studies and those of your friends and family, but if you do, be aware that you won’t have anyone reviewing your work. If you make a mistake or should have approached something differently, and you’re working alone, there’s no one to tell you.
You could work as a search angel for others. I have mixed emotions about this, in part due to the lack of review and oversight. But also, in part because “free search angels” perpetuate the idea that genealogy “should be” free.

If you want to work in IGG, after training, an internship under an established mentor is ABSOLUTELY ESSENTIAL for a minimum of 100 or so successful closures.

Genealogists and genetic genealogists have the ethical responsibility to NOT MAKE MISTAKES when working on other people’s family. You need to know what you know, what you don’t know, when to get help, from where and with whom.

Networking Opportunity

A Facebook group named “Genealogy Jobs” has been established to discuss opportunities and all of the topics surrounding this subject.

There’s a Genealogy Career Day event on April 22^nd where you can interact with professionals including authors, freelance genealogists, certified genealogists, business owners, and an investigative genetic genealogist. Take a look at the topics. If you’re considering whether or not you want to go pro, you’ll be interested. You can sign up here.

The sessions will be uploaded to their YouTube channel, here, after the event.

I hope you’ve found this article useful and helps you decide if this profession is for you. If so, create a plan and execute.

If you decide you do want to go pro, I wish you the best and welcome you to the fast-paced world of professional genealogy or its specialty, genetic genealogy.

X Chromosome Master Class

Posted on March 28, 2023 by Roberta Estes

The X chromosome can be especially useful to genetic genealogists because it has a unique inheritance path. Thanks to that characteristic, some of the work of identifying your common ancestor is done just by simply HAVING an X match.

Unfortunately, X-DNA and X matching is both underutilized and somewhat misunderstood – in part because not all vendors utilize the X chromosome for matching.

The X chromosome has the capability of reaching further back in time and breaking down brick walls that might fall no other way.

Hopefully, you will read this article, follow along with your own DNA results and make important discoveries.

Let’s get started!

Who Uses the X Chromosome?

The X chromosome is autosomal in nature, meaning it recombines under some circumstances, but you only inherit your X chromosome from certain ancestors.

It’s important to understand why, and how to utilize the X chromosome for matching. In this article, I’ve presented this information in a variety of ways, including case studies, because people learn differently.

Of the four major testing vendors, only two provide X-DNA match results.

FamilyTreeDNA – provides X chromosome results and advanced matching capabilities including filtered X matching
23andMe – provides X chromosome results, but not filtered X matching without downloading your results in spreadsheet format
Ancestry and MyHeritage do not provide X-DNA results but do include the X in your raw DNA file so you can upload to vendors who do provide X matching
GEDmatch – not a DNA testing vendor but a third-party matching database that provides X matching in addition to other tools

It’s worth noting at this point that X-DNA and mitochondrial DNA is not the same thing. I wrote about that, here. The source of this confusion is that the X chromosome and mitochondrial DNA are both associated in some way with descent from females – but they are very different and so is their inheritance path.

So, what is X-DNA and how does it work?

What is X-DNA?

Everyone inherits two copies of each of chromosomes 1-22, one copy of each chromosome from each of your parents.

That’s why DNA matching works and each match can be identified as “maternal” or “paternal,” depending on how your match is related to you. Each valid match (excluding identical by chance matches) will be related either maternally, or paternally, or sometimes, both.

Your 23^rd chromosome is your sex determination chromosome and is inherited differently. Chromosome 23 is comprised of X and Y DNA.

Everyone inherits one copy of chromosome 23 from each parent.

Males inherit a Y chromosome from their father, which is what makes males male. They do not inherit an X chromosome from their father.
Males always inherit an X chromosome from their mother.
Females inherit an X chromosome from both parents, which is what makes them female. Females have two X chromosomes, and no Y chromosome.

Chromosome 23	Father Contributes	Mother Contributes
Male Child	Y chromosome	X chromosome
Female Child	X chromosome	X chromosome

X-DNA and mitochondrial DNA are often confused, but they are not the same thing. In fact, they are completely different.

Mitochondrial DNA, in BOTH males and females is always inherited from only the mother and only descends from the direct matrilineal line, so only the mother’s mother’s mother’s direct line. X DNA can be inherited from a number of ancestors based on a specific inheritance path.

Everyone has both X-DNA AND mitochondrial DNA.

Because males don’t inherit an X chromosome from their father, X chromosome matching has a unique and specific pattern of descent which allows testers who match to immediately eliminate some potential common ancestors.

Males only inherit an X chromosome from their mother, which means they can only have legitimate X matches on their mother’s side of their tree.
Females, on the other hand, inherit an X chromosome from both their mother and father. Their father only has one X chromosome to contribute, so his daughter receives her paternal grandmother’s X chromosome intact.
Both males and females inherit their mother’s X chromosome just like any of the other 22 autosomes. I wrote about chromosomes, here.

However, the unique X chromosome inheritance path provides us with a fourth very useful type of DNA for genealogy, in addition to Y-DNA, mitochondrial and autosomal DNA.

For the vendors who provide X-matching, it’s included with your autosomal test and does not need to be purchased separately.

The Unique X Chromosome

The X chromosome, even though it is autosomal in nature, meaning it does recombine and divide in certain circumstances, is really its own distinct tool that is not equivalent to autosomal matching in the way we’re accustomed. We just need to learn about the message it’s delivering and how to interpret X matches.

FamilyTreeDNA is one of two vendors who utilizes X chromosome matching, along with 23andMe, which is another good reason to encourage your matches at other vendors to upload their DNA file to FamilyTreeDNA for free matching.

The four major vendors do include X-DNA results in their raw DNA download file, even if they don’t provide X-matching themselves. This means you can upload the results to either FamilyTreeDNA or GEDmatch where you can obtain X matches. I provided step-by-step download/upload instructions for each vendor here.

Let’s look how X matching is both different, and beneficial.

My X Chromosome Family Tree

We are going to build a simple case study. A case study truly is worth 1000 descriptions.

This fan chart of my family tree colorizes the X chromosome inheritance path. In this chart, males are colored blue and females pink, but the salient point is that I can inherit some portion of (or all of) a copy of my X chromosome from the colorized ancestors, and only those ancestors.

Because males don’t inherit an X chromosome from their father, they CANNOT inherit any portion of an X chromosome from their father’s ancestors.

Looking at my father’s half of the chart, at left, you see that I inherited an X chromosome from both of my parents, but my father only inherited an X chromosome from his mother, Ollie Bolton. His father’s portion of the tree is uncolored, so no X chromosome could have descended from his paternal ancestors to him. Therefore he could not pass any X chromosome segments to me from his paternal side – because he doesn’t have X DNA from his father.

Hence, I didn’t inherit an X chromosome from any of the people whose positions in the chart are uncolored, meaning I can only inherit an X chromosome from the pink or blue people.

Essentially any generational male to male, meaning father/son relationship is an X-DNA blocker.

I know positively that I inherited my paternal grandmother, Ollie Bolton’s entire X chromosome, because hers is the only X chromosome my father, in the fan chart above, had to give me. His entire paternal side of the fan chart is uncolored.

Men only ever inherit their X chromosome from their mother. The only exception to this is if a male has the rare genetic condition of Klinefelter Syndrome, also known as XXY. If you are an adult male, it’s likely that you’ll already know if you have Klinefelters, so that’s probably the last possibility you should consider if you appear to have paternal X matches, not the first.

Sometimes, men appear to have X matches on their father’s side, but (barring Klinefelter’s) this is impossible. Those matches must either be identical by chance, or somehow related in an unknown way on their mother’s side.

Everyone inherits an X chromosome from their mother that is some combination of the X from her father and mother. It’s possible to inherit all of your maternal grandmother or maternal grandfather’s X chromosome, meaning they did not recombine during meiosis.

Using DNA Painter as an X Tool

I use DNAPainter to track my matches and correlate segments with ancestors.

I paint my DNA segments for all my chromosomes at DNAPainter which provides me with a central tracking mechanism that is visual in nature and allows me to combine matches from multiple vendors who provide segment information. I provide step-by-step instructions for using DNAPainter, here.

This is my maternal X chromosome with my matches painted. I’ve omitted my matches’ names for privacy.

On the left side of the shaded grey column, those matches are from my maternal grandmother’s ancestors. On the right side, those matches are from my maternal grandfather’s ancestors.

The person in the grey column descends from unknown ancestors. In other words, I can tell that they descend from my maternal line, but I can’t (yet) determine through which of my two maternal grandparents.

There’s also an area to the right of the grey column where there are no matches painted, so I don’t know yet whether I inherited this portion of my X chromosome from my maternal grandmother or maternal grandfather.

The small darker pink columnar band is simply marking the centromere of the chromosome and does not concern us for this discussion.

In this summary view of my paternal X chromosome, above, it appears that I may well have inherited my entire X chromosome from my paternal great-grandmother. We know, based on our inheritance rules that I clearly received my paternal grandmother’s X chromosome, because that’s all my father had to give me.

However, by painting my matches based on their ancestors, and selecting the summary view, you can see that most of my paternal X chromosome can be accounted for, with the exception of rather small regions with the red arrows.

It’s not terribly unusual for either a male or female to inherit their entire maternal X chromosome from one grandparent, or in this case, great-grandparent.

Of course, a male doesn’t inherit an X chromosome from their father, but a female can inherit her paternal X chromosome from either or both paternal grandparents.

Does Size Matter?

Generally speaking, an X match needs to be larger than a match on the other chromosomes to be considered genealogically equivalent in the same timeframe as other autosomal matches. This is due to:

The unique inheritance pattern, meaning fewer recombination events occurred.
The fact that X-DNA is NOT inherited from several lines.
The X chromosome has lower SNP density, meaning it contains fewer SNPs, so there are fewer possible locations to match when compared to the other chromosomes.

I know this equivalency requirement sounds negative, but it’s actually not. It means 7 cM (centimorgans) of DNA on the X chromosome will reach back further in time, so you may carry the DNA of an ancestor on the X chromosome that you no longer carry on other chromosomes. It may also mean that older segments remain larger. It’s actually a golden opportunity.

It sounds much more positive to say that a 16 cM X match for a female, or a 13 cM X match for a male is about the same as a 7 cM match for any other autosomal match in the same generation.

Of course, if the 7 cM match gets divided in the following generation, it has slipped below the matching threshold. If a 16 or 13 cM X match gets divided, it’s still a match. Plus, in some generations, if passed from father to daughter, it’s not divided or recombined. So a 7 cM X match may well be descended from ancestors further back in time.

X Chromosome Differences are Important!

Working with our great-great grandparent’s generation, we have 16 direct ancestors as illustrated in the earlier fan chart.

Given that females inherit from 8 X-chromosome ancestors in total, they are going to inherit an average of 45.25 cM of X-DNA from each of those ancestors. Females have two X chromosomes for a total length of 362 cM of X-DNA from both parents.

A male only has one X chromosome, 181 cM in length, so he will receive an average of 36.2 cM from each of 5 ancestors, and it’s all from his mother’s side.

In this chart, I’ve shown the total number of cMs for all of the autosomes, meaning chromosomes 1-22 and, separately, the X for males and females.

The average total cM for chromosomes 1-22 individually is 304 cM. (Yes, each chromosome is a different length, but that doesn’t matter for averages.)
That 304 cM can be inherited from any of 16 ancestors (in your great-grandparent’s generation)
The total number of cM on the X chromosomes for both parents for females totals 362
The total cM of X-DNA for males is 181 cM
The calculated average cM inherited for the X chromosome in the same generation is significantly different, shown in the bottom row.

The actual average for males and females for any ancestor on any random non-X chromosome (in the gg-grandparent generation) is still 19 cM. Due to the inheritance pattern of the X chromosome, the female X-chromosome average inheritance is 45.25 cM and the male average is 36.2 cM, significantly higher than the average of 19 cM that genetic genealogists have come to expect at this relationship distance on the other chromosomes, combined.

How Do I Interpret an X Match?

It’s important to remember when looking at X matching that you’re only looking at the amount of DNA from one chromosome. When you’re looking at any other matching amount, you’re looking at a total match across all chromosomes, as reported by that vendor. Vendors report total matching DNA differently.

The total amount of matching autosomal DNA does not include the X chromosome cMs at FamilyTreeDNA. X-DNA matching cMs are reported separately.
The total amount of matching autosomal DNA does include the X chromosome cMs in the total cM match at 23andMe
X-DNA is not used for matching or included in the match amount at either MyHeritage or Ancestry, but is included in the raw DNA data download files for all four vendors.
The total match amount shows the total for 22 (or 23) chromosomes, NOT just the X chromosome(s). That’s not apples to apples.

Therefore, an X match of 45 cM for a female or 36 for a male is NOT (necessarily) equivalent to a 19 cM non-X match. That 19 cM is the total for 22 chromosomes, while the X match amount is just for one chromosome.

You might consider a 20 cM match on the regular autosomes significant, but a 20 cM X-only match *could* be only roughly equivalent to a 10ish cM match on chromosomes 1-22 in the same generation. That’s the dog-leg inheritance pattern at work.

This is why FamilyTreeDNA does not report an X-only match if there is no other autosomal match. A 19 cM X match is not equivalent to a 19cM match on chromosomes 1-22. Not to mention, calculating relationships based on cM ranges becomes more difficult when the X is included.

However, the flip side is that because of the inheritance pattern of the X chromosome, that 19 cM match, if valid and not IBC, may well reach significantly further back in time than a regular autosomal matches. This can be particularly important for people seeking either Native or enslaved African ancestors for whom traditional records are elusive if they exist at all.

Critical Take-Away Messages

Here are the critical take-away messages:

Because there are fewer ancestral lineages contributing to the tester’s X chromosome, the amount of X chromosomal DNA that a tester inherits from the ancestors who contribute to their X chromosome is increased substantially.
The DNA of the contributing ancestors is more likely to be inherited, because there are fewer other possible contributing ancestors, meaning fewer recombination events or DNA divisions/recombinations.
X-DNA is also more likely to be inherited because when passed from mother to son, it’s passed intact and not admixed with the DNA of the father.
X matches cannot be compared equally to either percentages or cM amounts on any of the other chromosomes, or autosomal DNA in total, because X matching only reports the amount on one single chromosome, while your total cM match amount reports the amount of DNA that matches from all chromosomes (which includes the X at 23andMe).
If you have X matches at 23andMe and/or FamilyTreeDNA, you can expect your total matching to be higher at 23andMe because they include the X matching cM in the total amount of shared DNA. FamilyTreeDNA provides the amount of X matching DNA separately, but not included in the total. MyHeritage and Ancestry do not include X matching DNA.

For clarity, at FamilyTreeDNA, you can see my shared DNA match with my mother. Of course, I match her on the total length of all my chromosomes, which is 3563 cM, the total Shared DNA for chromosomes 1-22. This includes all chromosomes except for the X chromosome which is reported separately at 181 cM. The longest contiguous block of shared DNA is 284 cM, the entire length of chromosome 1, the longest chromosome.

Because I’m a female, I match both parents on the full length of all 23 chromosomes, including 181 cM on both X chromosomes, respectively. Males will only match their mother on their X chromosome, meaning their total autosomal DNA match to their father, because the X is excluded, is 181 cM less than to their mother.

This difference in the amount of shared DNA with each parent, plus the differences in how DNA totals are reported by various vendors is also challenging for tools like DNAPainter’s Shared cM Tool which is based on the crowd sourced Shared cM Project that averages shared DNA numbers for known relationships at various vendors and translates those numbers into possible relationships for unknown matches.

Not all vendors report their total amount of shared DNA the same way. This is true for both X-DNA and half identical (HIR) versus fully identical (FIR) segments at 23andMe. This isn’t to say either approach is right or wrong, just to alert you to the differences.

Said Another Way

Let’s look at this another way.

If the average on any individual chromosome is 19 cMs for a relationship that’s 5 generations back in time. The average X-DNA for the same distance relationship is substantially more, which means that:

The X-DNA probably reaches further back in time than an equivalent relationship on any other autosome.
The X-DNA will have (probably) divided fewer times, and more DNA will descend from individual ancestors.
The inheritance path, meaning potential ancestors who contributed the X chromosomal DNA, is reduced significantly.

It’s challenging to draw equivalences when comparing X-DNA matching to the other chromosomes due to several variables that make interpretation difficult.

Based on the X-match size in comparison to the expected 19 cM single chromosome match at this genealogical distance, what is the comparable X-DNA segment size to the minimum 7 cM size generally accepted as valid on other chromosomes? What would be equal to a 7 cM segment on any other single random autosomal match, even though we know the inheritance probabilities are different and this isn’t apples to apples? Let’s pretend that it is.

This calculation presumes at the great-great-grandparent level that the 19 cM is in one single segment on a single chromosome. Now let’s divide 19 cM by 7 cM, which is 2.7, then divide the X amounts by the same number for the 7 cM equivalent of 16.75 cM for a female and 13.4 cM for a male.

When people say that you need a “larger X match to be equivalent to a regular autosomal match,” this is the phenomenon being referenced. Clearly a 7 cM X match is less relevant, meaning not equivalent, in the same generation as a 7 cM regular autosomal match.

Still, X matching compared to match amounts shown on the other chromosomes is never exact;u apples to apples because:

You’re comparing one X chromosome to the combined DNA amounts of many chromosomes.
The limited recombination path.
DNA from the other autosomes is less likely to be inherited from a specific ancestor.
The X chromosome has a lower SNP density than the other chromosomes, meaning fewer SNPs per cM.
The X-DNA may well reach further back in time because it has been divided less frequently.

Bottom Line

The X chromosome is different and holds clues that the other autosomes can’t provide.

Don’t dismiss X matches even if you can’t identify a common ancestor. Given the inheritance path, and the reduced number of divisions, your X-DNA may descend from an ancestor further back in time. I certainly would NOT dismiss X matches with smaller cMs than the 13 and 16 shown above, even though they are considered “equivalent” in the same generation.

X chromosome matching can’t really be equated to matching on the other chromosomes. They are two distinct tools, so they can’t be interpreted identically.

Different vendors treat the X chromosome differently, making comparison challenging.

23andMe includes not only the X chromosome in their cM total, but doubles the Fully Identical Regions (FIR) when people, such as full siblings, share the same DNA from both parents. I wrote about that here.
Ancestry does not include the X in their cM match calculations.
Neither does MyHeritage.
FamilyTreeDNA shows an X match only when it’s accompanied by a match on another chromosome.

The Shared cM Project provides an average of all of the data input by crowdsourcing from all vendors, by relationship, which means that the cM values for some relationships are elevated when compared to the same relationship or even same match were it to be reported from a different vendor.

The Best Part!

The X chromosome inheritance pattern means that you’re much more likely to carry some amount of a contributing ancestor’s X-DNA than on any other chromosome.

X-DNA may well be “older” because it’s not nearly as likely to be divided, given that there are fewer opportunities for recombination.
When you’re tracking your X-DNA back in your tree, whenever you hit a male, you get an automatic “bump” back a generation to his mother. It’s like the free bingo X-DNA square!
You can immediately eliminate many ancestors as your most recent common ancestor (MRCA) with an X-DNA match.
Because X-DNA reaches further back in time, sometimes you match people who descend from common ancestors further back in time as well.

If you match someone on multiple segments, if one of those matching segments is X-DNA, that segment is more likely to descend from a different ancestor than the segments on chromosomes 1-22. I’ve found many instances where an X match descends from a different ancestor than matching DNA segments on the autosomes. Always evaluate X matches carefully.

Sometimes X-DNA is exactly what you need to solve a mystery.

Ok, now let’s step through how to use X-DNA in a real-life example.

Using X DNA to Solve a Mystery

Let’s say that I have a 30 cM X match with a male.

I know immediately that our most recent common ancestor (MRCA) is on HIS mother’s side.
I know, based on my fan chart, which ancestral lines are eliminated in my tree. I’ve immediately narrowed the ancestors from 16 to 5 on his side and 16 to 8 on my side.
Two matching males is even easier, because you know immediately that the common ancestor must be on both of their mother’s sides, with only 5 candidate lines each at the great-great-grandparent generation.

Female to female matches are slightly more complex, but there are still several immediately eliminated lines each. That means you’ve already eliminated roughly half of the possible relationships by matching another female on their X chromosome.

In this match with a female second cousin, I was able to identify who she was via our common ancestor based on the X chromosome path. In this chart, I’m showing the relevant halves of her chart at left (paternal), and mine (maternal), side by side.

I added blockers on her chart and mine too.

As it turns out, we both inherited most of our X chromosome from our great-grandparents, marked above with the black stars.

Several lines are blocked, and my grandfather’s X chromosome is not a possibility because the common ancestor is my maternal grandmother’s parents. My grandfather is not one of her ancestors.

Having identified this match as my closest relative (other than my mother) to descend on my mother’s maternal side, I was able to map that portion of my X chromosome to my great-grandparents Nora Kirsch and Curtis Benjamin Lore.

My X Chromosome at DNA Painter

Here’s my maternal X chromosome at DNAPainter and how I utilized chromosome painting to push the identification of the ancestors whose X chromosome I inherited back an additional two generations.

Using that initial X chromosome match with my second cousin, shown by the arrow at bottom of the graphic, I mapped a large segment of my maternal X chromosome to my maternal great-grandparents.

By viewing the trees of subsequent X maternal matches, I was then able to push those common segments, shown painted directly above that match with the same color, back another two generations, to Joseph Hill, born in 1790, and Nabby Hall. I was able to do that based on the fact that other matches descend from Joseph and Nabby through different children, meaning we all triangulate on that common segment. I wrote about triangulation at DNAPainter, here.

I received no known X-DNA from my great-grandmother, Nora Kirsch, although a small portion of my X chromosome is still unassigned in yellow as “Uncertain.”

I received a small portion of my maternal X chromosome, in magenta, at left, from my maternal great-great-grandparents, John David Miller and Margaret Lentz.

The X chromosome is a powerful tool and can reach far back in time.

In some cases, the X, and other chromosomes can be inherited intact from one grandparent. I could have inherited my mother’s entire copy of her mother’s, or her father’s X chromosome based on random recombination, or not. As it turns out, I didn’t, and I know that because I’ve mapped my chromosomes to identify my ancestors based on common ancestors with my matches.

X-DNA Advanced Matches at FamilyTreeDNA

At FamilyTreeDNA, the Advanced Matches tab includes the ability to search for X matches, either within the entire database, or within specific projects. I find the project selection to be particularly useful.

For example, within the Claxton project, my father’s maternal grandmother’s line, I recognize my match, Joy, which provides me an important clue as to the possible common ancestor(s) of our shared segments.

Joy’s tree shows that her 4-times great-grandparents are my 3-times great-grandparents, meaning we are 4^th cousins once removed and share 17 cM of DNA on our X chromosome across two segments.

Don’t be deceived by the physical appearance of “size” on your chromosomes. The first segment that spans the centromere, or “waist” of the chromosome, above, is 10.29 cM, and the smaller segment at right is 7.02 cM. SNPs are not necessarily evenly distributed along chromosomes.

Remember, an X or other autosomal match doesn’t necessarily mean the entire match is contained in one segment so long as it’s large enough to be divided in two parts and survive the match threshold.

It’s worth noting that Joy and I actually share at least two different, unrelated ancestral lines, so I need to look at Joy’s blocked lines to see if one of those common ancestral lines is not a possibility for our X match. It’s important to evaluate all possible ancestors, plus the inheritance path to eliminate any lineage that involves a father to son inheritance on the X chromosome.

Last but not least, you may match on your X chromosome through a different ancestor than on other chromosomes. Every matching segment has its own individual history. It’s not safe to assume.

Now, take a look at your X chromosome matches at FamilyTreeDNA, 23andMe, and GedMatch. What will you discover?

Ancestry to Delete WorldConnect Trees and Shut Down RootsWeb Mailing Lists – Prepare NOW

Posted on February 19, 2023 by Roberta Estes

This is a dark day indeed.

Ancestry, who acquired RootsWeb, including the mailing lists and WorldConnect Trees back in the year 2000 is going to delete both.

The original purchase agreement reportedly included the provision to keep both free, but I never heard anything about a provision to keep them intact. A lot changes in 23 years in terms of technology, but other companies have updated infrastructure and maintained service for their customers. Ancestry can too.

The RootsWeb mailing lists will be gone April 6, and the WorldConnect trees on April 15^th.

Ancestry has removed many RootsWeb features over the years. Blogger Margaret O’Brien reviewed what was left in October 2020, here.

This isn’t the first time Ancestry has deleted an essential database. In 2014, they deleted their own Y and mitochondrial DNA database, followed by the Sorenson DNA database in 2015, despite petitions to reconsider and offers within and outside of the genealogy community to keep both alive.

Here we are again. Another crushing blow to the genealogy community in terms of irrecoverable record loss.

RootsWeb Mailing Lists

You’ll see this notice if you go to the main RootsWeb page.

What I don’t know is whether this means that the RootsWeb lists will be entirely deleted, or they will be kept intact in a similar format as Ancestry did when they purchased, then shut down the Genealogy.com trees, articles and forum in 2003.

I would think that if Ancestry had planned to keep anything in place, or maintain the RootsWeb list information in any way, they would have said so. The posting functionality has been gone for years, but we were still able to find information posted previously.

If you need something from the RootsWeb lists, assume that Ancestry is doing exactly what they said, and obtain it NOW!!!

WorldConnect Trees

The WorldConnect trees will be gone too. Back in April of 2019, Ancestry substantially changed the format of the trees, along with the web links. People could not find their way “back” to trees through links they had previously used.

Worse yet, tree contributors often included substantial notes, plus sources. In the “new” format, all notes were deleted, and sources, when included, were incomplete.

For users, this purge was gutting when so much information was included, and then, was entirely gone. Genealogists used to be able to contact tree-submitters, and even download some trees, but that functionality has been gone now for years.

Case in point, I’d love to find or make contact with Jim Weber who maintained an absolutely wonderful tree, above, complete with both text and sources for Medieval genealogical individuals.

If you know Jim Weber, PLEASE put us in touch.

Now, Jim’s tree will be gone and according to Ancestry, WorldConnect trees will be ported to Ancestry later in 2023. I can only HOPE that Ancestry replaces the text they stripped out in 2019 which removed a huge amount of Jim and other people’s work. However, that’s doubtful.

I wonder if these trees will be available for free or only to paying subscribers.

RootsWeb Message Boards and Hosted Webpages

The intertwined history of Ancestry and RootsWeb websites is complex and confusing. FamilySearch provides background information, here.

It’s unclear what will happen to the Message Boards and RootsWeb Hosted Websites.

For example, this unpublished manuscript of Indian Atrocities Along the Clinch, Powell and Holston Rivers of Southwest Virginia 1773-1794 by Emory L. Hamilton is invaluable and the Russell County, VA site is the ONLY place this is document available.

The Russell County site is a VAGENWEB site but it’s hosted by RootsWeb.

If you’re depending on any RootsWeb hosted site, I’d be making alternate plans.

Here’s the GenWeb index site with the following notice.

I can’t imagine that Ancestry is going to invest any resources in anything RootsWeb anymore, although I have not heard chatter from GenWeb site administrators.

Steps to Take NOW

The best plan of attack is to recover and save anything you can from RootsWeb lists, meaning locations or surnames of interest.

The index of RootsWeb Mailing Lists is here.

Make Your Voice Heard

It’s difficult to provide feedback to Ancestry, but try.

At the top of your Ancestry page is a Help button which includes a Support page which has a Chat Bot, but no phone numbers.

I could not find a support phone number on my page, but I found 1-800-615-6560 and 1-800-262-3787 as their corporate numbers.

The Ancestry CEO is Deb Liu.

Don’t Rely on the Wayback Machine

Don’t rely on the Wayback Machine at the Internet Archive for two reasons. The Wayback Machine is a wonderful archival resource, but the sites have to be crawled to be archived.

The WorldConnect trees were never crawled and those links are not there today. I tried that to find Jim Weber’s original tree entries with their wonderful notes – to no avail. Entering the current page links produces the same result. It’s easy to prevent the Wayback Machine from crawling sites and Ancestry has apparently done so.

For sites like the Russell County GenWeb site, the primary page itself was crawled, but the sections of the Indian Atrocities book were not. So if the site disappears, you’ll be able to see what you want, and used to be there, but can no longer get there. The Wayback Machine doesn’t always crawl buried links.

Time is of the Essence

Begging and pleading with Ancestry, including petitions from the genealogy community, have been of absolutely no use in the past. Let’s hope that perhaps this time is different and an organization like FamilySearch or the Library of Congress or even the Allen County Public Library will be selected to be an electronic repository for the RootsWeb list contents.

Don’t count on it, though, and do what you need to do for your genealogy, now.

Ancestry – It Doesn’t Have to Be This Way

It really doesn’t have to be this way. There is absolutely no benefit to anyone by deleting this information forever when there are other viable options with non-competitors.

Ancestry can position themselves as responsible stewards and write their corporate legacy in a positive way instead of creating a nightmare scenario.

I hope Ancestry preserves this priceless information contributed over three decades by thousands of researchers, many of whom are deceased now. That an entire generation of information that is irrecoverable. It’s literally erasing our family history and burning the digital genealogy library of Alexandria.

PLEASE. DON’T. DO. THAT

Ancestry, if you’re not going to preserve the lists in any format, at LEAST donate the information to FamilySearch to incorporate into the FamilySearch Library.

That’s the responsible stewardship approach, rather than having a huge digital bonfire, again.

I’m sure FamilySearch would gladly preserve these records and make their contents available to everyone, honoring the original intent and all of the contributors who trusted Ancestry.
