RootsTech Day 3 – Jewish DNA, Schmoozing and the Flapper Party

Day 3 at RootsTech was characterized by meeting lots of people, talking to several vendors and a party. Plus, I finally got to attend a session. Yes, really!

Ok, confession, I offered to help the presenter in order to garner a seat in the room. It was well worth a small amount of effort on my part to be able to see Bennett Greenspan, CEO and founder of Family Tree DNA present on The DNA of the Jewish People.

For those who don’t know, Bennett and his partner Max Blankfeld are the founding fathers of the direct to consumer genetic industry with the birth of Family Tree DNA 18 years ago.

I love Bennett’s DNA tie!

Even though Family Tree DNA hosts the annual conference for project administrators, Bennett has never presented at his own conference. I’ve heard him present once before, and he’s one of two speakers whose sessions I’d attend if they were talking about making mud pies. (Judy Russell is the other one.)

Bennett certainly didn’t let the audience down.

He began by telling folks how, just before his bar mitzva, his grandmother passed away. At the cemetery, his mother took his hand and walked him around, introducing him to the graves and family members buried there. Bennett didn’t realize how many relatives they had in Kansas.

Later that day, as family members arrived at the house to console the family, Bennett walked from person to person interviewing them about their memories of the “old country.” Bennett said, in their thick old-world accents, they told him about various family members, providing a link back in time.

Bennett then drew his first pedigree chart. I’m just amazed that he still HAS this chart. Thankfully, someone saved it. Little did he know how prophetic this would be or what staying power it would have. Nor could he have ever dreamt that his genealogy addiction was destined to someday change the world for all genealogists.

Indeed, Bennett was hooked at a very young age.

After Bennett sold his photographic supply company about 20 years ago, he became “too helpful” at home, offering to reorganize his wife’s pantry, and let’s just say that he got sent to his room. However, it just happens that in the room were his boxes of genealogy and well…history was about to be written.

In 1996 and 1997, Bennett had read two academic studies written about Y DNA in men. The first study was about the Jewish Cohen lineage, and the second was about the Jefferson males and Sally Hemmings.

Bennett’s Jewish family was torn apart by WWII and those who survived were scattered to the winds. This history makes genealogy particularly difficult for Jewish people, both the record destruction in Europe and the fact that the family remnants are so widely scattered and often lost to each other.

In Bennett’s case, he found a Nitz family in Argentina that claimed to be from the same village as his maternal grandmother’s Nitz family, and he wanted to verify that it was the same family by Y DNA testing – just like the Cohen study and the Jefferson/Hemmings case.

Bennett called Dr. Michael Hammer at the University of Arizona who was one of the authors on the Cohen paper, and whose lab had processed the samples. Dr. Hammer told Bennett that they only did academic processing, not for consumers. Bennett asked Dr. Hammer where he could turn to write a check and get an answer, but Dr. Hammer informed Bennett that such a company or location didn’t exist. Little did Dr. Hammer know that Bennett was an entrepreneur whose wife had banished him to timeout, in essence because he “retired” too young and was bored and underfoot.

Here’s what happened next!

I love to hear Bennett tell this story.

As a result, Family Tree DNA was born.

Bennett’s question about his Nitz line was indeed answered by a perfect Y DNA match. Indeed, it was the same family line!

Bennett then proceeded to search for Greenspan males, but that answer didn’t arrive for more than another decade. Bennett tested a lot of Greenspans, but it wasn’t until he met a Mr. Green at a conference that he found a match.

Jewish men fall into specific haplogroups or clusters, sometimes referred to as clans, on the Y DNA phylotree. The same is true for mtDNA, but that wasn’t the topic of his presentation.

Therefore, by testing a male, you can tell by his haplogroup and his matches whether or not he is Jewish.

The Ashkenazi and Sephardic Jews are very similar in their haplogroup breakdown and distribution, as are the rest of the non-Jewish residents of the Middle East.

They do, after all, originally descend from the same ancestors.

You can see the difference in the haplogroup spread between the people with Middle Eastern heritage, above, and the Ukraine, below.

These slides refute the theory that the Russian Khazars converted to Judaism en masse and subsequently migrated to eastern Europe. If this were the case, the DNA of the Ashkenazi Jews would be split much more closely along Ukrainian lines than Middle Eastern lines, and you can see for yourself which pie chart the Ashkenazi population more closely resembles.

The real message here is that thanks to DNA testing, we know that the sons of the Levant are far more alike than different – and that the Ashkenazi Jews are indeed from the Middle East and not from Russia.

Bennett’s family is from Eastern Europe, so the last thing he expected to discover was that his family was actually a displaced Sephardic line – but alas, through DNA matching and following the path of the DNA, that’s exactly what Bennett discovered.

As Bennett said, it rocked his world. No oral history reflected the 1492 expulsion of his family from Spain. This information gave him a new lens into the fate of his family when the Jews were displaced from Spain, penniless, their property confiscated, and leaving hurriedly to avoid death.

Bennett may never know their names, but he knows where they traveled on their long, perilous journey of over 2000 years from the Levant to Spain, then to Eastern Europe and finally into Argentina and the States.

I’ve summarized Bennett’s presentation significantly, but Bennett’s family history, revealed by Y DNA is a powerful story of family reunification.

Meet and Greet

In the Starbucks in the hotel, my 7th cousin, Laurel, found me and we talked about our common genealogy in Wilkes County, NC – the Sarah Rash (1748-1829) and Robert Shepherd (1739-1817) lines. If these are your lines too, please give a shout out.

I discovered that Laurel is going to be returning to Wilkes County for additional research, and she discovered that I know the location of the now-bulldozed-into-the-creek cemetery. Yes, we’re going to exchange information.

We’ve actually chatted a few times over the past few days and I’ve enjoyed it immensely.

On to the conference.

By day 3, I’ve finally developed a sense, at least somewhat, of the lay of the land. RootsTech is massive and the convention center is laid out anything but intuitively.

I walked by the theater in Lisa Louise Cooke’s genealogy Gems booth and caught a sentence where the presenter was explaining about cluster research, also known as FAN – friends and neighbors. In essence, people traveled in packs and you’ll tend to find them together. I wanted to agree vehemently, but did so silently and was very glad to see others listening attentively.

On down the aisle, I spotted an ad for DNA charts. As irritating as I find the ethnicity estimates, I must admit, these are really attractive.

However, I then spied the wall chart.

How fun is this? A gift maybe? How about adding the haplogroup for each person on the chart? So many possibilities. I can see a wall…

Speaking of walls, Living DNA created a “photo booth” in their booth, and David Nicholson, one of the Living DNA Founders and I hammed it up a bit. It’s always nice to meet the people who own and run the various companies. David and I have spoken and skyped previously, but never managed to be in the same place at the same time until now.

Most of the DNA vendors had long lines throughout the conference. That’s the good news, because no matter where you’ve tested, you’ll be getting new matches soon.

I stood in line to purchase a Living DNA kit for a friend, so I eaves-dropped anonymously.

Living DNA indicates that they provide a “3 in one” test, meaning autosomal ethnicity estimates (no matching yet, but anticipated this year), a mitochondrial haplogroup for your direct matrilineal line, and if you are a male, a Y DNA haplogroup for your paternal line.

For the sake of clarity, men receive 3, but women receive a “2 in one” since they have no Y chromosome.

I’m still hoping to be able to connect and have a few minutes to sit down and discuss Living DNA development for 2018.  Hopefully maybe tomorrow.

By now everyone should know that I find the full Y and mitochondrial DNA test, which provides you with actual test results and matching for those lines, extremely beneficial. I want to be very clear that knowing your Y and mtDNA haplogroup is very interesting and can be useful, but it’s not the same thing as receiving the actual results which can provide you with a significant history, along with matching.

Y and mitochondrial DNA is not an alternative to autosomal DNA testing, but these types of DNA tests supplement and enhance each other.

Of the major vendors, Family Tree DNA is the only vendor who offers that level of testing and has a data base for Y and mitochondrial DNA matching.

I’m so grateful that Family Tree DNA continues to offer these tests, although the autosomal market clearly outstrips the Y and mtDNA market. At trade shows, I think offering multiple types of tests is actually a detriment to Family Tree DNA, because they have to take time to educate their customers as to the different types of DNA that can be tested, ask about their goals, and then advise as to the appropriate test for the customer’s specific situation.

Above, in the Family Tree DNA booth, Bennett Greenspan is explaining the various types of tests to a potential customer.

Ran into Tom MacEntee again. It’s too bad he blends into the background and is so shy. Wait till you see what he’s wearing at the party later in the evening. OK, OK, I’ll shown you now.

Tom looks stunning in his tiara, doesn’t he!

Now, in the gratitude department – meet Dave Robison.

Dave introduced himself to me by saying something like, “You don’t know me, but you were such an inspiration to me when I was just getting started.” I was kind of taken aback, but then he continued by saying that he was somewhat doubtful of where he was “going,” so to speak, and that he had e-mailed me and I had answered him. From that, he decided that if I could do this, so could he, and lo and behold, he has, in spades.

Dave is now a professional genealogist who also donates a great deal of his time to several genealogical organizations. Please check out Dave’s story here.

Part of Dave’s trip to Salt Lake was to visit the Family History Library to perform some client work. On Saturday, I escaped to the library as well. (Don’t worry, you’re going along.) As luck would have it, we both found ourselves having lunch at the closest restaurant. Of course, we broke bread (or ate salad actually) together and had a lovely, lovely meal. I can’t wait to see Dave again.

Dave’s introduction moved me greatly. So often, we really never know the extent of the difference a kind word at the right time and place may make to someone.

I’m very grateful for Dave telling me, because it’s all too easy to be grouchy and tired when answering the 235th e-mail of the day.

I’m so pleased to have a new friend too.

Wandering on down the aisle, my eye was drawn to a ring that looked like it might be a helix. Could it be?

I do sometimes think I’m married to DNA.

Whoever thought you’d see the day when helix jewelry was available in a bead booth?

With earrings to match.

If you’re interested, I’m sure The Bead Farm would gladly ship.

Anyone watch Relative Race? BYU TV describes this show as, “With their own DNA as a roadmap, and $25,000 on the line, four couples must race coast-to-coast and discover a different relative every day.”

The season premier is March 4th!

Do they actually drive these brightly colored cars in the series? Obviously, I’ve never watched. Clue me in, someone…

Next, I had an amazing surprise.

Last summer, when Jim and I were in Europe chasing my ancestors across the continent, we met a lovely couple on the same journey. We enjoyed several meals together, parting ways and promising to keep in touch, with the best of intentions. However, life just got in the way, until today.

I looked up, and there stood my friend, Lisa Hunt. Of course, entirely out of context, I recognized her but for a moment, was somewhat confused. It’s a very long way from the Rhine River to Salt Lake City.

As it turns out, Lisa was at the conference hoping to meet up with a new cousin and stumbled across me! No, I’m not the cousin.

If you have a tree at Family Search, and you register for the conference, the app will search your tree and the trees of other attendees and tell you how many cousins you have at RootsTech, who they are and how you are related – with the idea that you can find each other. What fun!

And yes, Lisa did find her cousin!

One of the booths I noticed was the Society of Mayflower Descendants.

As luck would have it, Jim Brewster who presented at RootsTech (and works for Family Tree DNA) is my cousin through the William Brewster line. For those who don’t know, William Brewster is one of the Mayflower passengers. Ironically, I applied last week to join this society, right after I documented my line in order to join the Mayflower DNA Project at Family Tree DNA. Do you have any Mayflower ancestors?

I came to RootsTech with a list of vendors that I absolutely wanted to see and meet. Pierre Cloutier who wrote Charting Companion was one of those people. I’ve used this product for years to produce great charts and reports. It works with almost any genealogy software!

Here, Pierre’s explaining the McGuire Method to a visitor. I wasn’t quite sure how he could have implemented this methodology, so he kindly explained it to me. Charting companion now includes special mtDNA lineages displayed on charts, X chromosome inheritance as well as the new McGuire methodology.

If you’re trying to figure out where a DNA tester places in a group of other testers, the McGuire Method will be helpful, and Pierre has automated this methodology. Thank you, Pierre!

Flapper Party

Apparently, the MyHeritage After-Party has become a RootsTech tradition, even though this is only the third year.

I found more photos online of the party than of any other single conference related event last year, and maybe more than all vendors and sessions combined.

Who says genealogists are boring people?

Yes, indeed, the party this year was themed. Fortunately, you didn’t have to dress the part to attend, but many did. I also discovered, albeit too late, that Salt Lake City has a costume rental where you can rent and return. I’ll file that one away for future use! I wonder what they have in “DNA.”

The best part of this party was networking with others. I’ll introduce you to a few people you may know from their blogs and online presence.

Leah LePerle Larkin, who blogs as The DNA Geek, and I are cousins several times over through our Acadian lines. One day, when we have a breather, maybe we’ll actually figure out exactly how many times we’re related. Acadian lines are like that.

We’ve known each other online for years now, and finally had a chance to sit down at a table and actually talk. No, not at the party, earlier.

From left to right, front row, Angie Bush, genetic genealogist with ProGenealogists, Leah LaPerle Larkin, me. Rear, left to right, Rob Warthen and Richard Weiss with DNAadoption and DNAGedcom and Jony Perle of DNAPainter fame, peeking over the top.

Upon arrival, supplies were provided at a craft table to create hats and headbands. When you’re late, you get to celebrate your Native heritage by sticking some feathers in your hair. That was fine with me. However, my headband was too tight, so I dispensed with the headband and instead, liberated an orange feather centerpiece to use as a “parasol.” Hey, be creative and go big or stay home.

To be clear, Richard had not sprouted an orange bird on this head – that’s my parasol in my hand positioned on his shoulder.

Richard is a far more talented dancer than I am, but I had loads of fun anyway! This is one place where, thankfully, you don’t have to be good to have fun.

Jessica Taylor with Legacy Tree Genealogists, at left, with unknown people at right and a special friend. I’m sure there’s a story, I just don’t happen to know what it is!

Line dancing, disco lights and costumes.

A huge thank you to our host, Gilad Japhet, CEO and founder of MyHeritage.

Tomorrow, you’re going with me to visit the Family History Library! Never been there?  Neither have I!

Who Tests the X Chromosome?

Recently, someone asked which of the major DNA testing companies test the X chromosome and which ones use the X in matching. How does this difference influence the quality of our matches?

Vendor X in Download File Uses X in Matching X Included in Total cM Count
23andMe Yes Yes Yes
Family Tree DNA Yes Yes (if have a match on another chromosome) No
Ancestry Yes *No No
MyHeritage Yes No No
GedMatch N/A Separately No

*If Ancestry did utilize the X in matching, it wouldn’t benefit customers because Ancestry does not show segment information by chromosome.  In other words, no chromosome browser.

Family Tree DNA includes any size X match IF and only if the two people already match on a different chromosome.

GedMatch, of course, isn’t a vendor who does DNA testing, so they don’t provide download files.  They are solely on the receiving end.

X CentiMorgan Counts

Due to variations in the way vendors calculate matches and total cM counts, your mileage may vary a bit.

In other words, the 23andMe cM total, if an X match is involved, may be slightly more than a match between the same two people at Family Tree DNA, where the X match cM is not included in the cM total.

Conversely, you won’t show an X match with someone at Family Tree DNA if there isn’t also another segment on a different chromosome that matches.

In general, due to the thin spread of SNPs on the X chromosome, you will need, on average, a cM match that is twice as large as on other chromosomes to be considered of equal weight.

In other words, a 10 cM match on the X chromosome would only be genealogically equivalent to approximately a 5 cM match on any other chromosome.

X matches really can’t be evaluated by the same rules as other chromosomes due both to their SNP paucity and their inheritance path, which is why most vendors don’t include those segments in the total cM count.

X Matches

While including the X chromosome cM count is problematic, X matching can be a huge benefit because of the unique inheritance path of the X chromosome.

In the article, X Marks the Spot, we discussed the inheritance path of the X chromosome for both males and females. Females inherit an X chromosome from both father and mother, which recombines just like chromosomes 1-22.  However, men only inherit an X from their mother, because they inherit a Y from their father instead of the X.  Therefore, males will only inherit an X from their mother, and females will only inherit their father’s mother’s X chromosome.

Charting Companion software works with your genealogy software of choice to produce a lovely fan chart where the contributors of my X chromosome are charted in color, above. You can read more about Charting Companion here.

The great news is that if you and a match share a significant portion of the X chromosome, meaning more than 15 cM which reduces the likelihood of an identical by chance match, the common ancestor (on that segment) has to come from an ancestor in your direct X path.

I’m always excited to see with whom I share an X.  That piece of information alone helps me focus my ancestor detective efforts on a specific portion of my tree.

Some X segments can remain intact for generations and may be very old.  So don’t be surprised if the common ancestor of the X segment and another matching segment may not be the same ancestor.

Sorting by X

I wasn’t able to find a way to sort by X chromosome matches at 23andMe, but you can sort by the X at both Family Tree DNA and GedMatch.

At GedMatch, X matching shows on the one-to-many match page.  You can sort by either Total X cM or Largest X cM by using the up and down arrows, at right, below, in the X DNA columns.

After you identify an X match, be sure to run the X one-to-one match option to verify.

My GedMatch matches cause me to wonder if 23andMe is using a different reporting threshold for the X chromosome, because one of my matches at GedMatch is a close family member with no X match at 23andMe, but a total of 32 X cM and with a longest segment of 14 X cM at GedMatch.

That same individual matches me with the largest X segment of 14 cM at Family Tree DNA as well.

Family Tree DNA X Match Phasing

At Family Tree DNA, on your Family Finder matches page, just click on the X-Match header (at right, below) to bring all of your X matches to the top of your list.

If you have linked any kits of relatives to your tree, you will see numbers of phased kits on the maternal and paternal tabs with the red and blue male and female icons. In the example above, I have 3313 matches total, with 744 being paternal, 586 being maternal.

Next, click on the maternal or paternal tab to see only the people with X matches who match you on the  your maternal and paternal lines. Matches are automatically sorted into maternal and paternal “buckets” for you. Remember to check the size of the X match before deciding about relevance.

Who is your largest X match that you don’t already know?  Maybe you can find your common ancestor today.

Have fun!!!

Using X and Mitochondrial DNA Charts by Charting Companion

Charting Companion by Progeny Genealogy interfaces with many genealogy software programs to produce lovely charts and graphs not available within the genealogy software applications themselves. I first installed Charting Companion when I used PAF and was very glad to see that it interfaces with RootsMagic too, the software I switched to when PAF was no longer supported. RIP PAF🙁

Over the past couple years, Charting Companion has implemented DNA focused reports. I covered their first report, the X Ancestor Chart when it was first introduced, but they have since added mtDNA charts, and most recently X Descendant Charts. I love these reports and how useful they are to the genealogist.

It’s important to understand that both your mitochondrial DNA and the X chromosome have special inheritance paths and therefore, special uses for genetic genealogy research. I wrote about the X chromosome here and here.

The article 4 Kinds of DNA for Genetic Genealogy is a brief description of the various kinds of DNA testing available to genetic genealogists, and who can test for which kind.

X Chromosome Inheritance Path

In males, the X chromosome is only inherited from the mother, because the father gives the male a Y chromosome, which is what makes the male, male. In females, the father contributes his X chromosome to his daughter, as does her mother. However, the father only received an X from his mother – so you can see that the inheritance pattern for the X chromosome is not the same as other chromosomes where all children receive 50% of their inherited DNA from each parent.

Because of this unusual inheritance pattern, you can easily tell whether an autosomal match that shares an X chromosome could descend from the ancestor you think they might. If you’re a male and you think an X match comes through your father or one of his ancestors – think again, because it can’t.

Here’s my hand-drawn chart of the ancestors that portions of my X chromosome could have descended from.

X Chart0001

Now that I have charting companion, I no longer have to hand draw this chart. Charting Companion does it quickly and easily for me. And it’s much, MUCH neater!

x fan

The X chromosome is tested as part of an autosomal DNA test, but not all vendors report X matches. Ancestry does not provide information about the chromosomes where you match anyone, so at Ancestry, there is no way to know if you match someone on the X chromosome. Family Tree DNA’s Family Finder test does test for and report X chromosome matching and so does GedMatch if you upload your raw data files from any vendor.

Mitochondrial DNA Inheritance Path

Mitochondrial DNA is not passed to the children from males. Females pass their mitochondrial DNA to both genders of their children, but only females pass it on.

This pedigree chart below shows the Y and mitochondrial DNA inheritance path for a brother and sister. Both siblings received their mother’s mtDNA, which reaches back in time directly up the matrilineal line ONLY.

Y and mito

The great news is that since the mitochondrial DNA is never admixed with the father’s DNA, it’s a direct pipeline that informs us about the matrilineal line for hundreds and thousands of years back in time.

The bad news is that in order to find out about the mitochondrial DNA of another ancestor in your tree – meaning all of your ancestors that don’t have red circles in the chart above, you must find someone descended from a female through all females to the current generation, which can be a male. Testing for mitochondrial DNA is available through Family Tree DNA.

Let’s say you want to find out about the mitochondrial DNA of your father’s mother to fill in one of the haplogroups in your DNA pedigree chart. You would need to locate an individual to test who carries your father’s mother’s mitochondrial DNA. Your father can test, if he’s living and willing. If your father is deceased, and he had no siblings, and his mother is deceased with no siblings, you’re going to have to go on back up that tree until you find someone with living descendants who descend through only females to the current generation, which can include males.

Charting companion makes finding those descendants easy.

Getting Started

You can purchase Charting Companion at this link. And for those of you wondering, no, I don’t have any financial interest in Charting Companion or Progeny Genelaogy, nor is this a paid article, nor do I receive any commission or kickback or anything like that if you purchase this product, nor am I related to or know the owner. I don’t accept or write any articles for pay from anyone or any company, ever, and never have. I did, however, receive a free update to the Charting Companion software I had already purchased, but you will too if you have already purchased version 6.

After installing Charting Companion, which is painless (I had to install the latest upgrade for this article), Charting Companion opens the file you indicate, which is typically your production file for your genealogy software. You’ll select the person you want to be reflected as the source or center of your charts or reports in the yellow Name field, shown below. In my case, I selected Barbara Dreschel to be the person around whom the reports will center.

In case you’re wondering, “Babbit” was her nickname and J1c2f is her mitochondrial DNA haplogroup.  The only effective way I’ve discovered to maintain haplogroup information is as a middle name, so that’s what you’re seeing.

chart-drechsel

Next, you’ll select the type of report that you want to create.

You’ll want to click on the “Charts and Reports” tab and for the X chromosome charts, you’ll want to select either the Ancestor Charts, or the Descendant Charts.

chart companion

Net, you’ll select the X version, which is located under “color” because the proper people are colorized in pink and blue.

Ancestor chart options

Ancestor X Charts

Ancestor charts generally start with you and work their way back in time.   My X version shows which ancestors I inherited my X chromosome from. This can be very helpful when evaluating matches. In some cases, you cannot have a match to a particular person on the X chromosome from the particular line in question.

Ancestor charts come in two flavors, one is a traditional ancestor chart, the fan version shown earlier in this article, and the second version is a pedigree chart.

x pedigree 1

x pedigree 2

These charts make it easy to see who you could have received your X chromosome from – so X matches must be from the pink and blue colored ancestors and cannot be from ancestors whose boxes are not colored.

For example, if I match a descendant of John Y. Estes, located at the top of the pedigree chart, above, on the X chromosome, I know the common ancestor that I received the X DNA from is NOT John Y. Estes, because I couldn’t have inherited any X DNA from him. That’s easy to discern, because there is no coloration in John Y.’s box. So an X match to a descendant of John Y. Estes is not FROM John Y. Estes. It’s either a false match or the matching X chromosome is from another common ancestor. Of course, that doesn’t mean we both aren’t descended from John Y. Estes – it only means that our X match is not from John Y.  I wrote about false matches here.

When I receive an X match to someone and we’re trying to find a common ancestor, I suggest that my match print this same chart for themselves and that will help them determine which ancestors or ancestral lines we might potentially have in common.

Descendant X Charts

Recently Charting Companion announced a new tool, Descendant X Charts. On these charts, the ancestor is the focus and the descendants who inherited their X chromosome are colored either pink or blue. Part of the Descendant X Chart for Barbara Drechsel is shown below. You can click on any graphic to enlarge.

chart-descendant-drechsel

Descendant Charts look a little different than Ancestor Charts. Don’t be confused by the white box between Elnora Kirsch and her daughters. That’s just her husband, Curtis Benjamin Lore. While he contributes an X chromosome (with daughters) or doesn’t (with sons,) it’s not HIS X chromosome we’re tracking in this chart, it’s the X chromosome of Barbara Drechsel. Curtis would be shown either on his own ancestor chart, or you can create a Descendant X Chart for Curtis.

You might notice in this diagram that this family is particularly prone to not having children. Trying to find ANY DNA participants has been very challenging. However, when I do find them (fingers crossed) I’ll know immediately if they (and I) could possibly carry the X chromosome of Barbara Drechsel by looking at these charts. I’m someplace to the left on this chart, but off the edge of the graphic above.

My favorite Charting Companion charts are still the fan charts though, shown below, because they are compact and succinct and you can see everything on one chart on one page.

chart-descendant-fan

Mitochondrial DNA Charts

To find descendants who carry the mitochondrial DNA of any female, select the person whose mtDNA-carrying descendants you want to find. Then click on the Charts and Reports tab and select the Descendant Chart. You’ll then see various options at the top, where you’ll want to click on the Contents tab.

chart-mtdna-menu

Select Mitochondrial DNA. Note that you can also select the Y chromosome DNA, but that’s much more evident if you’re looking for a male, because the surname stays the same, so DNA testing candidates are generally rather obvious.

On the mtDNA Descendants Chart above, the people in pink and blue carry the mtDNA of Barbara Drechsel. The blue people, males, won’t pass it on to their offspring, but the pink people, females, will if they have offspring. You can see that many females in this family did not have children, so there are several dead ends for Barbara’s mtDNA, including one more daughter who is off of the right hand side of the page. On your computer, you can scroll and the printed reports allow you to overlap.

The Mitochondrial DNA Chart is a great tool to find out who carries the mitochondrial DNA of any ancestor.

Summary

I love tools that help people understand their DNA and how it’s useful to their genealogy. The X charts make seeing the X inheritance path so much easier than trying to explain in verbiage (or drawing by hand) – and provides an easy visual to quickly identify whether a particular ancestor could potentially be responsible for an X DNA match.

For mitochondrial DNA, the charting tool makes the task of finding appropriate descendants to test much easier. It can also work in reverse. If you want to know if a particular person is a candidate for testing for a specific ancestor’s mtDNA, it’s easy to see immediately if their box is colored pink or blue.

I especially love tools that are ubiquitous and run with almost any software package and that don’t require special plugins. Furthermore, I’m particularly enamored with vendors who listen to and take suggestions to heart from their customer base. No, this suggestion wasn’t mine, but the X Descendant Chart was implemented within a week of when it was suggested by a customer. Two weeks later, it was in production – and now all Charting Companion customers benefit. A big thank you to Pierre Clouthier at Progeny Genealogy.
