Free MyHeritage LIVE 2018 Webinars Are Online

MyHeritage LIVE 2018 webinars

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

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

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

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

I do have a recommendation for you though.

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

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

Happy Holidays to You

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

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

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

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

Upload Your DNA

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

Click here to upload your DNA for free.

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

Test Your DNA

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

End of Free DNA Uploads to MyHeritage November 30th

5 day countdown

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

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

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

Here’s the exact quote from their blog:

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

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

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

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

Need help? No problem!

Step-By-Step Upload Instructions

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

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

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

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

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

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

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

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

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

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

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

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

That’s where the confusion starts.

Enter Elizabeth Johnson

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

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

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

Seems logical, right?

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

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

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

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

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

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

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

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

The problem is that it was wrong.

DNA Upsets the Apple Cart

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

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

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

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

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

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

The proof doesn’t get any better than this.

Except…

One Final Hitch

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

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

Let’s look at the various possible relationships.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

What Other Tools are Available?

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

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

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

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

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

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

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

Conclusion

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

Crumley birth timeline

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

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

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

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

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

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

Whole Genome Sequencing – Is It Ready for Prime Time?

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

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

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

I have no affiliation with either company.

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

The four questions you need to ask yourself are:

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

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

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

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

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

Let’s start with some basics.

What Is Whole Genome Sequencing?

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

Exome Sequencing – A Subset of Whole Genome

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

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

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

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

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

Autosomal Testing for Genealogy

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

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

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

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

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

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

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

Whole Genome Sequencing Questions

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

Genomics Education Programme [CC BY 2.0 (https://creativecommons.org/licenses/by/2.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Utilization

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

A Specific Medical Question

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

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

Take a look at both sample reports, here.

Health and Wellness in General

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

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

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

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

Medical Testing

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

Genealogical Comparisons

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

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

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

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

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

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

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

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

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

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

Summary

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

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

The Question – Will I Order?

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

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

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

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

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

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

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

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

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

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

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

Jacob Lentz’s Signatures: Cursive and Genetic – 52 Ancestors #216

What is a signature anyway?

A signature is defined as a mark or something that personally identifies an individual. A form of undeniable self-identification.

Of course, that’s exactly why I seek my ancestors’ signatures, both their handwriting and their genetic signature.

Jacob Lentz was born in Germany in 1783 and died in 1870 in Ohio.

Most documents of that timeframe contained only facsimiles of actual signatures. Original deeds indicate that the document was signed, but when recorded in deed books at the courthouse, the clerk only transcribed the signature. The person recorded the physical deed that they had in their hand, and then took it home with them. Therefore, the deed book doesn’t hold the original signature – the original deed does. I was crestfallen years ago when I discovered that fact. ☹

Hence, the actual physical signature of an ancestor is rare indeed.

Recently, I’ve been lucky enough to find not one, but two actual signatures of Jacob Lentz – plus part of his genetic signature as well.

Jacob’s Handwritten Signatures

When Jacob Lenz, later Lentz in the US, petitioned to leave Germany in 1817, he signed the petition document.

The original document is in the “Weinstadt City Archive”, which kindly gave permission for the reproduction and was graciously retrieved by my distant cousin, Niclas Witt. Thank you very much to both!

Here’s Jacob’s actual signature.

The story of Jacob’s life and immigration, and what a story it is, is recorded here, here, here and here.

Jacob’s life has a missing decade or so, after he completed his indentured servitude about 1820 or 1821 in Pennsylvania and before he arrived in Montgomery County, Ohio about 1830. In Ohio, he purchased land and began creating records. That’s where I found him initially.

Jacob’s youngest child, Mary Lentz, was born in May or June of 1829, before leaving Pennsylvania. She married in Montgomery County, Ohio on December 19, 1848 to Henry Overlease. That marriage document contains the signature of her father, Jacob Lentz.

This signature is slightly different than the German one from 31 years earlier, but it’s still clearly our Jacob, as the document states that the parents have signed. It looks like he’s also incorporated the “t” into the name now as well.

Jacob Lentz’s Genetic Signatures

As I was celebrating the discovery of not one, but two versions of Jacob’s written signature, I realized that I carry part of Jacob’s genetic signature too, as do others of his descendants. I just never thought of it quite like that before.

His genetic signature is every bit as personal, and even better because it’s in me, not lost to time.

There are three types of DNA that can provide genetic signatures of our ancestors; mitochondrial, Y DNA and autosomal.

Mitochondrial DNA

Mitochondrial DNA is passed from mothers to all genders of their children, but only their daughters pass it on. Therefore, it’s primarily unchanged, generation to generation.

Being a male, Jacob couldn’t pass his mitochondrial DNA on to his descendants, so we have to discover Jacob’s mitochondrial DNA by testing someone else who descends from his mother’s direct matrilineal line through all females but can be a male in the current generation.

Unfortunately, we haven’t been able to discover Jacob’s mitochondrial DNA that he inherited from his matrilineal line, meaning his mother’s mother’s mother’s line.

However, we only identified his parents a few months ago. Most of Jacob’s family didn’t immigrate, so perhaps eventually the right person will test who descends from his mother, or her matrilineal line, through all women to the current generation.

Jacob’s matrilineal line is as follows, beginning with his mother:

  • Jacob’s mother – Maria Margaretha Gribler born May 4, 1749 and died July 5, 1823 in Beutelsbach, married Jakob Lenz November 3, 1772.
  • Her mother, Katharina Nopp born April 23, 1707 and died November 27, 1764 in Beutelsbach, married Johann Georg Gribler on October 26, 1745.
  • Agnes Back/Beck born November 26, 1673 in Aichelberg, Germany, died February 10, 1752 in Beutelsbach and married Johann Georg Nopp from Beutelsbach.
  • Margaretha, surname unknown, from Magstadt who married Dionysus Beck who lived in Aichelberg, Germany.

If you descend from any of these women, or their female siblings through all females to the current generation, I have a DNA testing scholarship for mitochondrial DNA at Family Tree DNA for you! I’ll throw an autosomal Family Finder test in too!

If you’d like a read a quick article about how mitochondrial, Y DNA and autosomal DNA work and are inherited, click here.

Y-DNA

On the other hand, Jacob did contribute his Y DNA to his sons. Lentz male descendants, presuming no adoptions, carry Jacob’s Y DNA signature as their own.

We are very fortunate to have Jacob Lentz’s Y DNA signature, thanks to two male Lentz cousins. I wrote about how unique the Lentz Y DNA is, and that we’ve determined that our Lentz line descends from the Yamnaya culture in Russia some 3500 years ago. How did we do that? We match one of the ancient burials. Jacob’s haplogroup is R-BY39280 which is a shorthand way of telling us about his clan.

On the Big Y Tree, at Family Tree DNA, we can see that on our BY39280 branch, we have people whose distant ancestors were found in two locations, France and Germany. On the next upstream branch, KMS67, the parent of BY39280, we find people with that haplogroup in Switzerland and Greece.

Our ancestors are amazingly interesting.

Autosomal DNA

Jacob shares his Y and mitochondrial DNA, probably exactly, with other relatives, since both Y and mitochondrial DNA is passed intact from generation to generation, except for an occasional mutation.

However, Jacob’s autosomal DNA was the result of a precise combination of half of his mother’s and half of his father’s autosomal DNA. No one on this earth had the exact combination of DNA as Jacob. Therefore, Jacob’s autosomal DNA identifies him uniquely.

Unfortunately, Jacob isn’t alive to test, and no, I’m not digging him up – so we are left to piece together Jacob’s genetic signature from the pieces distributed among his descendants.

I realized that by utilizing DNAPainter, which allows me to track my own segments by ancestor, I have reconstructed a small portion of Jacob’s autosomal DNA.

Now, there’s a hitch, of course.

Given that there are no testers that descend from the ancestors of either Jacob or his wife, Fredericka Ruhle, at least not that I know of, I can’t sort out which of these segments are actually Jacob’s and which are Fredericka’s.

In the chart above, the tester and my mother match each other on the same segments, but without testers who descend from the parents of Jacob and Fredericka, through other children and also match on that same segment, we can’t tell which of those common segments came from Jacob and which from Fredericka. If my mother and the tester matched a tester from Jacob’s siblings, then we would know that their common segment descended through Jacob’s line, for example.

Painting Jacob’s Genetic Signature

The segments in pink below show DNA that I inherited from either Jacob or Fredericka. I match 8 other cousins who descend from Jacob Lentz and Fredericka Ruhle on some portion of my DNA – and in many cases, three or more descendants of Jacob/Fredericka match on the same exact segment, meaning they are triangulated.

As you can see, I inherited a significant portion of my maternal chromosome 3 from Jacob or Fredericka, as did my cousins. I also inherited portions of chromosomes 7, 9, 18 and 22 from Jacob or Fredericka as well. While I was initially surprised to see such a big piece of chromosome three descending from Jacob/Fredericka, Jacob Lentz and Fredericka Ruhle aren’t really that distantly removed – being my great-great-great-grandparents, or 5 generations back in time.

Based on the DNAPainter calculations, these segments represent about 2.4% of my DNA segments on my maternal side. The expected amount, if the DNA actually was passed in exactly half (which seldom happens,) would be approximately 3.125% for each Jacob and Fredericka, or 6.25% combined. That means I probably carry more of Jacob/Fredericka’s DNA that can eventually be identified by new cousin matches!

Of course, my cousins may well share segments of Jacob’s DNA with each other that I don’t, so those segments won’t be shown on my DNAPainter graph.

However, if we were to create a DNAPainter chart for Jacob/Fredericka themseves, and their descendants were to map their shared segments to that chart, we could eventually recreate a significant amount of Jacob’s genetic signature through the combined efforts of his descendants – like reassembling a big puzzle where we all possess different pieces of the puzzle.

Portions of Jacob’s genetic signature are in each of his descendants, at least for several generations! Reassembling Jacob would be he ultimate scavenger hunt.

What fun!

MyHeritage LIVE Conference Day 2 – The Science Behind DNA Matching    

The MyHeritage LIVE Oslo conference is but a fond memory now, and I would count it as a resounding success.

Perhaps one of the reasons I enjoyed it so much is the scientific aspect and because the content is very focused on a topic I enjoy without being the size and complexity of Rootstech. The smaller, more intimate venue also provides access to the “right” people as well as the ability to meet other attendees and not be overwhelmed by the sheer size.

Here are some stats:

  • 401 registered guests
  • 28 countries represented including distant places like Australia and South America
  • More than 20 speakers plus the hands-on workshops where specialist teams worked with students
  • 38 sessions and workshops, plus the party
  • 60,000 livestream participants, in spite of the time differences around the world

I was blown away by the number of livestream attendees.

I don’t know what criteria Gilad Japhet will be using to determine “success” but I can’t imagine this conference being judged as anything but.

Let’s take a look at the second day. I spent part of the time talking to people and drifting in and out of the rear of several sessions for a few minutes. I meant to visit some of the workshops, but there was just too much good, distracting content elsewhere.

I began Sunday in Mike Mansfield’s presentation about SuperSearch. Yes, I really did attend a few sessions not about DNA, but my favorite was the session on Improved DNA Matching.

Improved DNA Matching

I’m sure it won’t surprise any of my readers that my favorite presentations were about the actual science of genetic genealogy.

Consumers don’t really need to understand the science behind autosomal results to reap the benefits, but the underlying science is part of what I love – and it’s important for me to understand the underpinnings to be able to unravel the fine points of what the resulting matches are and are not revealing. Misinterpretation of DNA results leading to faulty conclusions is a real issue in genetic genealogy today. Consequently, I feel that anyone working with other people’s results and providing advice really needs to understand how the science and technology together works.

Dr. Daphna Weissglas-Volkov, a population geneticist by training, although she clearly functions far beyond that scope today, gave a very interesting presentation about how MyHeritage handles (their greatly improved) DNA Matching. I’m hitting the high points here, but I would strongly encourage you to watch the video of this session when they are made available online.

In addition to Dr. Weissglas-Volkov’s slides, I’ve added some additional explanations and examples in various places. You can easily tell that the slides are hers and the graphics that aren’t MyHeritage slides are mine.

Dr. Weissglas-Volkov began the session by introducing the MyHeritage science team and then explaining terminology to set the stage.

A match is when two people match each other on a fairly long piece of DNA. Of course, “fairly long” is defined differently by each vendor.

Your genetic map (of your chromosomes) is comprised of the DNA you inherit from different ancestors by the process of recombination when DNA is transferred from the parents to the child. A centiMorgan is the relatively likelihood that a recombination will occur in a single generation. On average, 36 recombinations occur in each generation, meaning that the DNA is divided on any chromosome. However, women, for reasons unknown have about 1.5 times as many recombinations as men.

You can’t see that when looking at an example of a person compared to their parents, of course, because each individual is a full match to each parent, but you can see this visually when comparing a grandchild to their maternal grandmother and their paternal grandmother on a chromosome browser.

The above illustration is the same female grandchild compared to her maternal grandmother, at left, and her paternal grandmother at right. Therefore the number of crossovers at left is through a female child (her mother), and the number at right is through a male child (her father.)

# of Crossovers
Through female child – left 57
Through male child – right 22

There are more segments at left, through the mother, and the segments are generally shorter, because they have been divided into more pieces.

At right, fewer and larger segments through the father.

Keep in mind that because you have a strand of DNA from each parent, with exactly the same “street addresses,” that what is produced by DNA sequencing are two columns of data – but your Mom’s and Dad’s DNA is intermixed.

The information in the two columns can’t be identified as Mom’s or Dad’s DNA or strand at this point.

That interspersed raw data is called a genotype. A haplotype is when Mom’s and Dad’s DNA can be reassembled into “sides” so you can attribute the two letters at each address to either Mom or Dad.

Here’s a quick example.

The goal, of course, is to figure out how to reassemble your DNA into Mom’s side and Dad’s side so that we know that someone matching you is actually matching on all As (Mom) or all Gs (Dad,) in this example, and not a false match that zigzags back and forth between Mom and Dad.

The best way to accomplish that goal of course is trio phasing, when the child and both parents are available, so by comparing the child’s DNA with the parents you can assign the two strands of the child’s DNA.

Unfortunately, few people have both or even one parent available in order to actual divide their DNA into “sides,” so the next best avenue is statistical phasing. I’ve called this academic phasing in the past, as compared to parental phasing which MyHeritage refers to as trio phasing.

There’s a huge amount of confusion about phasing, with few people understanding there are two distinct types.

Statistical phasing is a type of machine learning where a large number of reference populations are studied. Since we know that DNA travels together in blocks when inherited, statistical phasing learns which DNA travels with which buddy DNA – and creates probabilities. Your DNA is then compared to these models and your DNA is reshuffled in order to assemble your DNA into two groups – one representing your Mom’s DNA and one representing your Dad’s DNA, according to statistical probability.

Looking at your genotype, if we know that As group together at those 6 addresses in my example 95% of the time, then we know that the most likely scenario to create a haplotype is that all of the As came from one parent and all of the Gs from the other parent – although without additional information, there is no way to yet assign the maternal and paternal identifier. At this point, we only know parent 1 and parent 2.

In order to train the computers (machine learning) to properly statistically phase testers’ results, MyHeritage uses known relationships of people to teach the machines. In other words, their reference panels of proven haplotypes grows all of the time as parent/child trios test.

Dr. Weissglas-Volkev then moved on to imputation.

When sequencing DNA, not every location reads accurately, so the missing values can be imputed, or “put back” using imputation.

Initially imputation was a hot mess. Not just for MyHeritage, but for all vendors, imputation having been forced upon them (and therefore us) by Illumina’s change to the GSA chip.

However, machine learning means that imputation models improve constantly, and matching using imputation is greatly improved at MyHeritage today.

Imputation can do more than just fill in blanks left by sequencing read errors.

The benefit of imputation to the genetic genealogy community is that vendors using disparate chips has forced vendors that want to allow uploads to utilize imputation to create a global template that incorporates all of the locations from each vendor, then impute the values they don’t actually test for themselves to complete the full template for each person.

In the example below, you can see that no vendor tests all available locations, but when imputation extends the sequences of all testers to the full 1-500 locations, the results can easily be compared to every other tester because every tester now has values in locations 1-500, regardless of which vendor/chip was utilized in their actual testing.

Therefore, using imputation, MyHeritage is able to match between quite disparate chips, such as the traditional Illumina chips (OmniExpress), the custom Ancestry chip and the new GSA chip utilized by 23andMe and LivingDNA.

So, how are matches determined?

Matching

First your DNA and that of another person are scanned for nearly identical seed sequences.

A minimum segment length of 6cM must be identified for further match processing to occur. Anything below 6cM is discarded at this point.

The match is then further evaluated to see if the seed match is of a high enough quality that it should be perfected and should count as a match. Other segments continue to be evaluated as well. If the total matching segment(s) is 8 total cM or greater, it’s considered a valid match. MyHeritage has taken the position that they would rather give you a few accidental false matches than to miss good matches. I appreciate that position.

Window cleaning is how they refer to the process of removing pileup regions known to occur in the human genome. This is NOT the same as Ancestry’s routine that removes areas they determine to be “too matchy” for you individually.

The difference is that in humans, for example, there is a segment of chromosome 6 where, for some reason, almost all humans match. Matching across that segment is not informative for genetic genealogy, so that region along with several others similar in nature are removed. At Ancestry, those genome-wide pileup segments are removed, along with other regions where Ancestry decides that you personally have too many matches. The problem is that for me, these “too matchy” segments are many of my Acadian matches. Acadians are endogamous, so lots of them match each other because as a small intermarried population, they share a great deal of the same DNA. However, to me, because I have one great-grandfather that’s Acadian, that “too matchy” information IS valuable although I understand that it wouldn’t be for someone that is 100% Acadian or Jewish.

In situations such as Ashkenazi Jewish matching, which is highly endogamous, MyHeritage uses a higher matching threshold. Otherwise every Ashkenazi person would match every other Ashkenazi person because they all descend from a small founder population, and for genealogy, that’s not useful.

The last step in processing matches is to establish the confidence level that the match is accurately predicted at the correct level – meaning the relationship range based on the amount of matching DNA and other criteria.

For example, does this match cluster with other proven matches of the same known relationship level?

From several confidence ascertainment steps, a confidence score is assigned to the predicted relationship.

Of course, you as a customer see none of this background processing, just the fact that you do match, the size of the match and the confidence score. That’s what genealogists need!

Matching Versus Triangulation Thresholds

Confusion exists about matching thresholds versus triangulation thresholds.

While any single segment must be over 6 cM in length for the matching process to begin, the actual match threshold at MyHeritage is a total of 8 cM.

I took a look at my lowest match at MyHeritage.

I have two segments, one 6.1 cM segment, and one 6 cM segment that match. It would appear that if I only had one 6 cM segment, it would not show as a match because I didn’t have the minimum 8 cM total.

Triangulation Threshold

However, after you pass that matching criteria and move on to triangulation with a matching individual, you have the option of selecting the triangulation threshold, which is not the same thing as the match threshold. The match threshold does not change, but you can change the triangulation threshold from 2 cM to 8 cM and selections in-between.

In the example below, I’m comparing myself against two known relatives.

You won’t be shown any matches below the 6 cM individual segment threshold, BUT you can view triangulated segments of different sizes. This is because matching segments often don’t line up exactly and the triangulated overlap between several individuals may be very small, but may still be useful information.

Flying your mouse over the location in the bubble, which is the triangulated segment, tells you the size of the triangulated portion. If you selected the 2 cM triangulation, you would see smaller triangulated portions of matches.

Closing Session

The conference was closed by Aaron Godfrey, a super-nice MyHeritage employee from the UK. The closing session is worth watching on the recorded livestream when it becomes available, in part because there are feel good moments.

However, the piece of information I was looking for was whether there will be a MyHeritage LIVE conference in 2019, and if so, where.

I asked Gilad afterwards and he said that they will be evaluating the feedback from attendees and others when making that decision.

So, if you attended or joined the livestream sessions and found value, please let MyHeritage know so that they can factor your feedback onto their decision. If there are topics you’d like to see as sessions, I’m sure they’d love to hear about that too. Me, I’m always voting for more DNA😊

I hope to hear about MyHeritage LIVE 2019, and I’m voting for any of the following locations:

  • Australia
  • New Zealand
  • Israel
  • Germany
  • Switzerland

What do you think?

MyHeritage LIVE 2018 Day 1 Photos, Details and Party

The MyHeritage parties are legendary. That in and of itself is a bit ironic, because Gilad Japhet, the founder and CEO is a rather reserved man. The words Gilad and party just don’t seem to fit together, but he certainly knows how to host an awesome party.

Know what? Genealogists will take time away from records to party, dress up and dance too. We aren’t serious all the time!

The article I wrote yesterday about the DNA announcements was quite hurried.

Now, it’s 4:30 AM, I’m terribly jet lagged so unexplainably awake, and since I can’t sleep, I’m writing this article to catch you up on Day 1 of the conference. Of course, this means that by about noon, I’ll be dying for a nap. You’ll have to watch my live panel discussion at 3:30 PM Oslo time today to see if you can tell I’m running on about 4 hours of sleep. (Don’t forget in the US some places changed to Daylight Savings time overnight.) Here’s the link to my article with the livestream link and the time zone calculator.

Day One in More Detail

MHLive Gilad opening crowd

Here’s Gilad just before he opened the conference. Everyone was excited. Don’t you love his shoes?

Before I go any further, I want to thank Gilad for the conference invitation and access to him and the team to be able to take these awesome photos and for the information provided.

Now, if you haven’t already done so, please go and read the day 1 announcement article, here.

I’d like to clarify a couple points and expand on that article.

I had dinner last night with Ran Snir, DNA Product Manager, along with fellow colleague Diahan Southard, and we discussed the new upcoming DNA related features. I’d like to clarify some terminology surrounding anticipated features.

Painting – The term “painting” was used yesterday, and in the context of what MyHeritage is doing, it does NOT mean the same thing as DNAPainter painting. I’ve written several articles about how I use DNAPainter, but the introductory article is here.

DNAPainter paints your own chromosomes only, identifying the segments of your ancestors. This is not what MyHeritage meant by painting. MyHeritage is referring to reconstructing your ancestors’ DNA.

Reconstructing Ancestral DNA – When MyHeritage referred to painting yesterday, they meant that several descendants’ DNA segments that they carry identically by descent (IBD) will be combined and “stitched together” to “create” a partial genome of that ancestor. No, they didn’t say exactly how this would be done, and no, they did not discuss how it would be managed. In other words, who controls the profile of the ancestor – and mitigates disputes about what segments should be, and should not be attributed to that ancestor.

For me, this raised several questions, but we’ll have to wait until the new feature is released to see how MyHeritage will deal with the inherent issues of:

  • Your most distant autosomal ancestor is actually a couple because you can’t yet divide the DNA into husband and wife.
  • The trees of the descendants need to be complete and accurate.
  • People descending from the same child of the ancestor will also carry the DNA of the wives in each generation, so they need to be compared to people descended from other children of the ancestor to ascertain that the DNA is of the ancestor – not of wives in downstream generations.
  • People tend to marry cousins, siblings, etc., especially when living in the same area. DNA from another line may be unknowingly introduced into two different children’s lines, appearing that the resulting segment comes from the ancestor (or ancestral couple) when in fact, it doesn’t.

These are challenges, not barriers, so let’s continue with Gilad’s presentation.

Extracting DNA from Old Envelopes and Stamps

In the next slides, Gilad discusses extracting DNA from old stamps and envelope seals – the goal being that the resulting file can be uploaded to MyHeritage so that your deceased relative’s DNA can be resurrected through the DNA held in the envelope stamp and seal – which they hopefully licked. This is something we’ve dreamed of (and attempted) since the beginning of DNA testing for genealogy. Apparently Gilad dreamed of it too, because several of his own items are being processed right now.

Gilad provided some examples of other types of stamps and seals that might contain the saliva of our ancestors. Think outside of the box, or in this case, outside of the envelope. No, hair and other items were not discussed. There was a sidebar discussion but at this point, only envelopes and stamps are being utilized.

Theory of Family Relativity

The last session of the day was presented by Maya Lerner, the VP of Product where she discussed, among other things, their new Theory of Family Relativity.

I apologize for the quality of some of these photos. I opted not to bring by larger camera to reduce travel weight, using my cell phone instead. I regret that choice.

The Theory of Family Relativity, currently under development will combine the DNA estimates of where a person is likely to fit into a tree with actual records from the MH database to show the most likely placement of a DNA match.

Today, when we have a match, based on the amount of shared DNA, MyHeritage estimates and illustrates the relationship position that this person holds in our tree, but does not show us on our actual tree itself where this person might fit. That’s up for us as genealogists to figure out.

As I understand the new feature, the relationship distance, shown above, will be combined with records such as phased DNA, census, birth, death, logical criteria (women don’t bear children at age 7 or 70) and other records which would exclude some relationships in our actual tree, while providing evidence for others.

New Features

Aside from the DNA announcements, MyHeritage is also introducing a lot of new non-DNA related features.

City Directories – For example, they are digitizing and indexing city directories. The great thing is that they aren’t just indexing names, but also addresses. As a genealogist, Gilad has personally discovered the usefulness of being able to search for an address in immigration records to view everyone, even with misspelled names, who claimed they were joining family at that specific address. It’s another clue.

European Newspapers – in multiple languages. Digitizing and indexing.

Other New Content – Czeck census, German registration records, Brazil records,

There are so many awesome new features coming, what should you be doing to prepare now?

What You Should Be Doing NOW

  • If you’ve tested elsewhere, upload your DNA raw data file to MyHeritage. The upload is FREE and so are all of the features, but ONLY until Dec. 1st. After that, there will be a fee associated with some advanced features. So upload your file and those of your family members (with permission of course) now. I wrote instructions about how to upload to MyHeritage here, to and from Family Tree DNA here, and from Ancestry here.
  • If you haven’t tested elsewhere, purchase a kit, or two. The more of your relatives such as parents, siblings (if your parents are gone,) aunts, uncles, cousins that you can test, the more information that can be learned about your genealogy and connections to others. Give DNA kits for the holidays. Take them to family reunions. Thanksgiving is coming. Kits are on sale right now for an amazing $49 each. Click here to purchase.
  • Be thinking about envelopes and stamps that your deceased family members have licked. Who else in your family, that you might be seeing over the holidays might have these types of items? The technology for extracting DNA from these prized genetic heirlooms may finally be ripe. We’re waiting for early samples submitted to see how successful this technology will be.

Party Time!!!

Ok, I know you’ve been patiently waiting for the party pictures.

MyHeritage is sponsoring the EuroVision Song Contest, so we were the lucky beneficiaries.

Two entertainments groups were featured. The first was a Norwegian folk group. The music was awesome, haunting and ethereal. Like nothing I’ve heard before. They actually make some of these sounds with their cheeks.

The second group was a contemporary band and they were amazing too. Did you know that genealogists love to dance? Must be in the genes!

For those of you wondering, yes, I really do have a halo, but it slips from time to time😊 Here’s living proof!

Thanks Gilad, for a great party to celebrate the MyHeritage wonderful new features😊

How exciting to be on the leading edge.

My Heritage Live 2018 – DNA Announcements

This is a quick and dirty update about DNA products and services at the MyHeritage LIVE conference, although increasingly, the line between DNA and rest of genealogy is entirely disappearing.

I spent most of day 1 in the DNA track, as you might imagine.

I’m trying to fit this article in between sessions and dinner so I apologize in advance for the brevity. I’m trying to provide you with the important information in a timely manner, so details and more photos will have to wait for another time.

Gilad Japhet, Founder and CEO of MyHeritage opened the conference and his keynote session was not only interesting, from a family history perspective, but also full of information about the future products and features.

The next sessions that I attended relative to DNA were:

  • MyHeritage DNA 101 by Ran Snir, the DNA Product Manager
  • MyHeritage DNA: Advanced Features, also by Ran
  • What’s Next: The MyHeritage Genealogy and DNA Roadmap by Maya Lerner, VP Product

The announcements from the above sessions combined were:

  • The MyHeritage DNA data base is now just under 2 million participants.
  • Shared Ancestral Places: Live now. An interactive map of the location and significant life events (birth, death, etc.) of you and your matches. This would be particularly useful if you don’t know how you match, no common surname, but you discover that you both have ancestors in the same location, or close proximity. The locations are geocoded to avoid issues such as spelling and inconsistent data entry.

This map illustrates the shared ancestral locations of other people who match me and my match.

By clicking on the pin above, I can see the location of Oley, PA and without looking further, I can tell you which family line this is.

This feature is not yet on the mobile app, but it will be updated soon.

  • Ancestor Reconstruction: Future feature. If multiple descendants of a particular ancestor test, MyHeritage will create a “kit” for your ancestor and combine the segments from the multiple descendants identified as originating with that ancestor. I have lots of questions about this feature, such as how other ancestors DNA would be eliminated, such as the wives of ancestors for starters. I’ll see if I can obtain clarification. Gilad referred to this as “painting,” but I’m not sure that this feature is painting in the way we think of DNAPainting – so I would not jump the conclusion that it is. What Gilad actually said was that MyHeritage was creating a tool to provide the reconstructed DNA of ancestors.
  • Envelopes and Stamps: Soon. MyHeritage is partnering with a third party (unnamed) firm to extract DNA from envelopes and stamps. The results will used to create a kit for that ancestor at MyHeritage. Cost was not discussed. Multiple extracted samples can be combined to create one more robust kit.
  • This technique will also be used to add the DNA of famous people to their database. Gilad did state in the examples of the people he discussed that they did not have any direct relatives, so he is cognizant of this ethical “brave new world.”
  • X chromosomal information will be added soon.
  • Maternal/paternal side match indicators will be added soon. Beta product shown.
  • Mass segment triangulation: Future. Gilad was asked about mass triangulation, and he stated that they were working on “something even better,” and someone else later added that they were going to do mass triangulations on specific segments.
  • Theory of Family Relativity. Future but under development. When you receive a new match, you will be able, based on the DNA segments PLUS all available and relevant records to view different theories of how this person might fit into your tree. Multiple theories may be shown to the user. Each theory will be presented to the user with a confidence level ranking.
  • Ethnicity update is coming next year. It will be more refined and include more areas. MyHeritage in their Tribal Quest program has been visiting people in remote or isolated locations, helping them to preserve their family stories and sampling their DNA as well. This helps MyHeritage to build reference models against which to compare their customer’s DNA for ethnicity predictions.

Oslo – Getting Acquainted

I hope you don’t mind, but you’re coming along with me again on a jaunt.

This time, of course, we’re going to Oslo for MyHeritage LIVE. #MHLIVE2018

The most convenient, meaning the fewest number of connections involved flying overnight and attempting to sleep sitting up in an airline seat. I left Wednesday afternoon and arrived in Oslo Thursday afternoon.

Landing at dawn at in Amsterdam.

That means the day you arrive, you’re terribly jet lagged AND in my case, you’ve walked from one end of the EXTREMELY large Schiphol Airport in Amsterdam to the other. This airport is the only airport I’ve ever seen where distances to gates are given in the number of minutes it takes to walk.

However, Schiphol is fun with lots of interesting shops selling everything from diamonds to chocolate.

The pragmatic Dutch people get right down to brass tacks!

My Scandinavian Connection

Norway has a very frustrating and special connection to me. My mitochondrial DNA full sequence matches are almost all to people from Norway and Sweden. Clearly, our common ancestor before the time of records that can be traced came from there.

My most distant matrilineal ancestor is found in German church records around 1700. Her ancestors were clearly not German, at least not on her mother’s side, and I have to wonder about the 30 Year’s War and if her ancestor wasn’t one of the women who accompanied the Swedish soldiers who marched through almost all of Germany. A map of the locations where Swedes were known to have traveled during that time is shown here. My ancestor was earliest found in the mustard colored region of this map about half way between Bamberg and the  Czech border, labeled Bohemia on the older map.

Somehow, my ancestor found herself in Germany and had children there. The telltale sign is in the J1c2f mitochondrial DNA that I myself carry – a distant vestige of my Scandinavian roots.

I’ve returned to the land of my ancestors – distant and unknown maybe – but my ancestors nonetheless. Illustrated succinctly by my matches throughout Norway and Sweden.

I’ve discovered that I love Scandinavia – and I must admit, for someone who doesn’t much care for the cold – that’s saying something!

Oslo

The airport is located about 54 km from the city itself. Train, bus and taxi service is available (word to the wise, use OsloTaxi if using a taxi) to the city itself.

The conference is being held at the Radisson Blu Hotel.

Notice the greenery on the roof.

I tried to stay awake my first day in Oslo, with a moderate amount of success. I did need lunch, so I now have a favorite new pub.

The atmosphere is wonderful and they have Ginger Joe’s Ginger Beer. I can’t manage to find Joe’s in the States, so if you see any, let me know where I might obtain said Ginger Beer. By the way, Ginger Beer (generically) comes in both the alcoholic and non-alcoholic variety, although Joe’s does have about as much alcohol as near-beer. It’s so pop-like that they often serve it over ice here.

That’s lentil soup and bar bread. Yum!

I love old-world pubs because there is nothing cookie-cutter about them and they all have their own unique personality.

Fantastic atmosphere. I’ll be back before my week here is over.

Friday

The long Scandinavian winter has begun, with dusk beginning about 2:30 and the sun setting about 4 in the afternoon.

Yesterday was relatively clear, but today is rainy and the rest of the week promises to be so as well.

Not to say that it rains a lot here and the residents are used to it, but even the baby buggies have raincoats here.

In case you didn’t know, the troll is the symbol of Norway. They are everyplace, both today and in legend.

At breakfast, I was reminded that the Norwegians have an acute sense of humor.

I googled and discovered that there is a quilt shop in Oslo. I had half a day today, so I decided to find the shop and get to know the city a bit.

Arriving by cab, I discovered the Kathrine Quilte Stue was closed. Thankfully, the cab driver translated the sign, and I heaved a sigh of relief to discover that it was only closed from 11:30-12:30. The time I arrived? 11:32

I walked a block in either direction when I spied a lovely bakery.

It seemed pretty busy, which is always a good sign. I decided to have something healthy for lunch. That is, right up until I went inside.

Here’s my compromise. Avocado toast and a cinnamon bun😊 What do you think?

I have to tell you, this was the best sesame cracker I’ve every tasted. Very savory and crunchy. This is why Scandinavian people generally aren’t heavy. Their health food is so doggone good.

Just ignore that cinnamon roll. Not there. Didn’t happen.

Ok, well, it did, BUT it was sweet but not overly sweet and no icing.

Perfect lunch.

However, it got even better when I discovered the lovely antiquarian book shop next door.

You may not know that I love maps, especially old maps, especially old maps of where my ancestors lived.

This lovely shop purveys maps from around the world. In the owner’s words, “The internet changed everything.”

I would like to have stayed longer, but the quilt shop was calling to me.

For some reason, Scandinavia, with their long cold winters, isn’t terribly interested in either quilts or quilting – with a few exceptions. Kathrine’s shop is cram packed full of quilts, fabric, patterns and more.

Treasures are buried just about everyplace. Of course I found some fabric for a souvenir. How could I not find fabric here?

The rose fabric makes me think of mother, whose ancestor’s were from here someplace of course. Bicycles are such a European thing. Many people ride for basic transportation, especially in the Netherlands.

I was reminded that even though many buildings have been renovated, at least the street-facing exterior, the underlying structure is still old, giving an old-world charm to the portions of buildings not normally seen by customers. This bathroom window is the only ventilation in a bathroom that is about 2 feet by 3 feet – if that large. Literally your knees were touching the door.

I decided I wanted to see the city and the walk back was only a couple of miles. With Google maps, what could possibly go wrong?

Let’s just say I did have a lovely walk through the city, just a bit longer than I anticipated.

Let me share some of the beautiful architecture with you.

Small shops interspersed with apartments.

Very little graffiti here.

Lots of cobblestones.

Plenty of parks and public areas. People walking dogs and children walking alone. Oslo is very safe.

Obviously, business vehicles, but they look like quilt patterns to me. These look like so much fun to drive!

It’s late fall here too.

Norway is one of the wealthiest countries on earth. The standard of living is high and their residents are very happy. Homelessness is almost nonexistent.

This style of stone walls with thick seams is very popular.

I’m not sure what these trees are, but I saw several.

Lots of gardens. This rose bush was not quite ready to surrender to fall just yet.

I love this picture, especially with the lost glove on top of the lower fence by the wall. You might surmise that Oslo is a city by the sea built on hills.

If you walk enough in a strange city, you might just run into a palace. I had no idea that the park I was walking through was actually the palace grounds.

Yes, the palace is guarded.

The palace sits on top of a hill.

Standing here, looking left, the Radisson is the large building just behind the trees.

Who knew?

Not sure what this building is, but there are a lot of embassies and ambassadors’ residences nearby.

Walking around the block behind the hotel, I found a combination antique shop/second hand store. What fun!

Treasure has to do with what you are looking for. Love this old sewing machine. I can image the original owner sewing in the long winter days. Maybe she (or he) made quilts.

I enjoy browsing because places like this always tell me something about the history and culture of the people.

Norwegians love to read.

By this time, the sun was already setting and conference registration had begun.

I met several people this evening at the reception, including many blog followers, and am looking forward to tomorrow’s sessions.

Remember to join by livestream or later, after MyHeritage has had the opportunity to edit and upload the sessions. As soon as it’s announced, I’ll let you know where you can find them. The recorded sessions will be free.

Here’s the link to my article with livestream link and the timezone converter.

Ethnicity – Far More than Percentages!

Since ethnicity results have been in the news recently, I thought this might be a good time to talk about how to squeeze more out of your ethnicity results than just percentages.

You do know there’s more, right? You can tell a lot more about where your ethnicity came from by who you match, and how. Vendors provide that information too, but you need to know where to look. Plus, I have some tips about how to use this information effectively.

Genealogists are always trying to squeeze every last drop of information out of every DNA test, so I’d like to illustrate how I use ethnicity in combination with shared matches at Ancestry, Family Tree DNA, MyHeritage and 23andMe. Each vendor has a few unique features and tools as well, plus people in their databases that other vendors don’t have.

Come along and see what you might discover!

Ancestry

Ancestry recently introduced a new ethnicity comparison feature so let’s start there. Ancestry’s new tool:

  • Compares the ethnicity of you and a match side by side.
  • Shows Shared Migrations
  • Shows you common matches with that person.

At Ancestry, I have a V1 (older) and a V2 (newer) test, so I’m comparing my own V1 to my own V2 test for purposes of illustration.

To start, click on DNA Matches. You’ll see a new blue compare button, beneath the green View Match button, at right.

Clink on any image to enlarge

Click on the blue Compare button. You’ll see a side by side display, shown below.

My V1, at left, compared to my V2 test, at right. My V2 test results do not have a photo uploaded, so you just see my initials. It’s interesting to note that even though these are both me, just tested on different chips, that my ethnicity doesn’t match exactly, although it’s mighty close.

Next, you’ll see the shared migrations between the two people being compared. This helps determine where your common ancestor might be found.

Last, you’ll see the shared matches between you and the other person. This means that those people match both you and the person you’re comparing against, suggesting a potential common ancestor.

On your matches page, you can also sort your matches by your regions.

Where Did Your Ethnicity Come From?

Ethnicity comparisons can be helpful, especially if you’re a person who carries DNA from different continents. I do not suggest trying to compare intra-continental estimates in the same way. It’s simply too difficult for vendors to separate DNA from locations that all border each other where countries are the size of states in the US, such as the Netherlands, Germany, France and Switzerland for example.

As I’ve said before, ethnicity results are only estimates, but they are relatively accurate at the continental level, plus Jewish, as illustrated below.

To be specific, these regions are the easiest for vendors to tell apart from the other regions:

  • European
  • African
  • Native American (North American, South American, Central American and Siberian in conjunction with the Americas)
  • Asian
  • Jewish

For example, if you are 30% African, 35% Native American and 35% European, you could use this information to form a hypothesis about how you match a particular individual or group of individuals.

If the person you match is 50% Asian and 50% African, it’s most likely that the region you match them on is the common African side.

Of course, the next step would be to look at the shared matches to see if those matches include your known relatives with African heritage. This is one reason I always encourage testing of relatives. Who you and your known relative both match tells you a lot about where the common ancestor of a matching group of individuals is found in your tree. For example, if someone matches you and a first cousin, then the common ancestor of the three people is on the side of your tree that you share with the first cousin.

Not exactly sure, or dealing with smaller amounts of continental ethnicity? There’s another way to work with ethnicity.

Ethnicity Match Chart

Make an Ethnicity Match Chart that includes the ethnicity of each person in the match group, as follows.

In this example, the only category in which all people fall is African, so that’s where I’d look in my tree first for a family connection.

Keep in mind that you match person 1, and people 2-4 match both you and person 1.

That does NOT mean that:

  • Person 2, 3 or 4 match each other.
  • Any of those people share the same ancestor with each other. Yes, you can match due to different ancestors that might not have anything to do with each other.
  • These people match on any of the same segments. You can’t view segments at Ancestry. You’ll have to transfer your results to Family Tree DNA, MyHeritage or GedMatch to do that.

Next, look at the trees for each person in the common match group and see if you can discern any common genealogy or even common geography. The best hints of course, at Ancestry, are those green leaf Shared Ancestor Hints. If you find a common ancestor or line, you’re well on your way to identifying how those people are related to you and potentially your match as well.

You could also use this methodology as an adaptation of or in tandem with the Leeds Method that I wrote about here.

Comparing Segments – Yes, You’ll Need To

Ancestry doesn’t offer a chromosome browser, but Family Tree DNA, MyHeritage, 23andMe and GedMatch all do, allowing you to view segments and triangulate. I always suggest uploading Ancestry results to GedMatch, Family Tree DNA and MyHeritage. 23andMe does not accept uploads.

You’ll find instructions for downloading from Ancestry here, uploading to Family Tree DNA here, and to MyHeritage here.

Other Vendors

Each vendor offers their own version of ethnicity comparison. All vendors offer in common with (ICW) and shared match tools too, so you can create your Ethnicity Match Chart for a specific group of people from any vendor’s results – although I don’t mix vendor results on one chart. Plus, every vendor has people in their matching database that no other vendor has, so fish in every pond.

Family Tree DNA

Family Tree DNA offers shared ethnicity information on the myOrigins map. To view, click on MyOrigins, then on View MyOrigins Map.

Testers who opt in can view their ethnicity as compared to their matches’ ethnicity. You can also sort by ethnicity as well as use the pin function at bottom right to drop Y and mtDNA most distant ancestor pins on the map.

Please note that this is NOT where your match lives, but is the location of their most distant matrilineal (mtDNA) or patrilineal (surname) known individual.

If you’re looking for Native American matches, for example, you might look for someone with some percentage of Native American autosomal DNA and/or Native American Y or mitochondrial haplogroups. Click on any pin to view that person and their ethnicity that matches yours. You can also search for a specific individual to see how your ethnicity lines up.

On your match list, look for common surnames with those matches, see who you match in common and check your matches’ trees.

Linking your DNA matches to their location in your tree enables you to participate in Phased Family Matching, meaning you can then select people that are assigned to your maternal or paternal sides to view in the chromosome browser.

When viewing all maternal (red icon) or all paternal (blue icon) matches together on the chromosome browser, the segments are automatically mathematically triangulated. All you need to do is identify the common ancestor!

I love Phased Family Matches. Family Tree DNA is the only vendor to offer this feature and to incorporate Y and mitochondrial DNA.

MyHeritage

MyHeritage provides multiple avenues for comparison, allowing users to select matches by their ethnicity, country or to simply compare their ethnicity to each other. To view matches by ethnicity, click on the Filter button, but note that not all ethnicity locations are included. You can also combine options, such as looking for anyone from the Netherlands with Nigerian DNA.

To view your matches ethnicity as compared to yours, click on the match and scroll down.

Look for people you match in common as well as the triangulation icon, shown at right, below. Another feature, SmartMatches (a filter option) sort for people who have common ancestors with you in trees.

I love triangulation and DNA SmartMatches and MyHeritage is the only vendor to offer this combination of tools!

23andMe

At 23andMe, you can see your ethnicity beside that of your match by clicking on DNA Relatives, on the Ancestry tab, then click on the person you wish to compare to. In my case, I’ve also taken the V3 and V4 test at 23andMe, so I’m comparing to myself.

At 23andMe, you can view which portions of your segments are attributed to which ethnicity. Under the Ancestry tab, click Ancestry Composition and scroll down to view your Ancestry Composition Chromosome Painting.

You can see my Native American segments on chromosomes 1 and 2.

Click on Scientific Details, then scroll to the bottom to download your ethnicity raw data that includes the segment detail for the location of those specific segments.

Utilizing these chromosome and segment locations with any other vendor who supports a chromosome browser, and determining which side that ethnicity descends through allows you to identify matches who should also carry segments of that same ethnicity at that same location.

Here’s my Native segment on chromosome 2 from the download file. Remember, you have two copies of every chromosome – and in my case, only one of those copies on Chromosome 2 is Native. I know it’s from my mother, so anyone matching me on my maternal side at this location on chromosome 2 should also have a Native segment, and our common ancestor is the source of our common Native American heritage.

23andMe is the only vendor to identify ethnicity segments.

23andMe does show matches in common and common matching segments on the chromosome browser, but they don’t support trees.

Your Turn!

If you carry ethnicity from multiple continents (plus Jewish), what hints can you derive from using your ethnicity as a match tool?
