Researching and Visiting Ireland

With my recent articles about Ireland, I’ve had lots of questions about visiting Ireland and researching Irish ancestors. Let’s talk about both!

Ireland is a wonderful place to visit. The people are genuinely friendly and outgoing, perhaps moreso than anyplace else in the world.

You can read about my adventures and share some of Ireland in the following articles:

Who Are The Irish?

The Irish are an ancient people with roots in the Neolithic hunter gatherer tribes who constructed the megalithic monuments more than 5000 years ago, followed by the Celts, Vikings, Normans and English. Today’s Irish are an amazing people with a wonderful sense of humor and unparalleled flexibility in the face of adversity. In other words, they are experts at making lemonade out of lemons. I suspect that’s what has at times made the unbearable, bearable, and ultimately insured their survival.

Let me give you an example.

I sat down on a tour bus for a short ride of about 10 minutes between two destinations.

A man traveling with a retiree’s club tour sat next to me, as all of the other seats were occupied.

Before sitting down, the man who I’d estimate to be on the far side of 4 score years, asked if he could sit beside me. I replied, “By all means, sit right down.”

He did and asked me if I was from the US. Laughing, I asked, “What was your first clue?” I obviously have a very distinct US accent.

We both laughed.

Then he looked at me, kind of sized me up, and asked, absolutely deadpan, “Will ye marry me?”

I could tell that this was just something he did and he was enjoying the shock value.

I told him that the ride was about 10 minutes and we could negotiate. He cheerfully said “OK!”

We started chatting about the location we had just visited and nothing in particular. In other words, the proposal was an ice-breaker and no serious negotiations were ensuing. (I was wearing a wedding band.)

Then, I asked him what women normally say when he proposes like that.

He looked at me and said, I his lovely Irish brogue, “Well, obviously no one has said yes yet or I wouldn’t still be askin’.”

I wish I could write in Irish brogue, which is what would be needed to truly convey this exchange.

I laughed till I cried. We parted friends. He has probably already forgotten about me, especially if someone has since taken him up on his proposal, but I’ll never quire forget him! After all, how many women get proposed to between Knowth and New Grange?

If you’re thinking he was the exception, he wasn’t – although granted, no one else proposed. However, many Irish extended themselves in the 10 days I visited and were exceptionally friendly and helpful at a level that many Americans would consider a borderline invasion of personal space.

For example, this is Edna, a lady that said hello in a pub during hurricane Ophelia and a few minutes later, we were best buddies.

This is simply consummate Ireland. In her words, “We do this all the time.”

Oh, and by the way, that’s a baby sized Guinness in my hand, just to see if I liked it.  I did, and thank you Edna! What a fun time we had in the middle of a hurricane.

Why Ireland?

Ireland has experienced significantly more migration and emigration than many other locations due to both religious conflicts and famine. When visiting the UCD Library, the curators of the Irish Folklore Project stated that there are far more Irish descendants scattered outside of Ireland than inside. In other words, the diaspora is larger than the homeland. I believe the diaspora is estimated to be about 70 million people with Irish roots, versus about 7 million current population by combining Ireland and Northern Ireland.

In my case, the Scots-Irish migrated to the US in early days, between 1717 and 1770, populating areas of Pennsylvania, Virginia, Tennessee and North Carolina. The Appalachian Mountains probably felt much like home.

The Scots-Irish were only Irish for a little more than a hundred years. Before that, they were Scottish and were only transplanted to Ireland in the early 1600s, beginning about 1606 when the Protestant Scots were settled in what is now Northern Ireland, near Ulster.

Most families stayed for 4, maybe 5 generations before leaving again for better opportunities, beginning about 1717 and included an Irish famine that occurred between 1740-1741.

We know in Ireland that the Scots-Irish lived in what is now Northern Ireland, in the Ulster Plantations.

A second wave of emigration occurred during a second Irish famine that occurred between 1845-1852.

Finding Family

And now, for the bad news – many Irish genealogy records were destroyed in the bombing and subsequent fire in Dublin that destroyed almost all of the records held in the Irish Public Record Office in 1922, making research before that time challenging at best.

Therefore, DNA testing is likely to help Irish families and descendants more than most. DNA has the power to help piece together the past and overcome those missing records. The Irish, at least those interested in genealogy, aren’t nearly as reticent to test as continental Europeans. But then again, continental Europeans generally haven’t lost their records at quite the same level as the Irish.

If you’re one of those people who are lucky enough to discover the location of your family homeland in Ireland – or home road or farm, you may want to visit. Even if you can’t find the exact location, Ireland isn’t a large country, and you may be able to get close.

Other researchers visit to perform the actual research in various archival facilities.

Regardless, I have a few tips and hints for you about what to expect, what to do, what not to do, and more.

Driving

JUST DON’T!!! The Irish drive on the “wrong side” of the road and the rules are different. You’ll get yourself or someone else killed. Seriously, don’t…really! Need convincing? Look at this intersection. Any idea what you’re supposed to do?

Parking is extra and in many places, you simply can’t, so you’re MUCH BETTER to take a taxi or a bus in larger cities.

Hire a driver. I hired Brian O’Reilly and I can’t say enough good things about him – not only as a driver but as a tour guide.

I would hire Brian again in a heartbeat and I now count him among my friends. Brian works with a cooperative of several other private drivers and guides, so if Brian isn’t available himself, he will help you arrange transportation and guide service for your needs. He can also respond on relatively short notice. Brian O’Reilly’s e-mail is Brian.oreilly101@yahoo.ie. Tell him Roberta sent you and that I said “hello.”

Brian and I had a really great time and I learned so much about the Irish culture I would never have learned on a canned tour.

Hire a taxi, not a chauffeur, when hiring a driver. Why? Because taxis can use bus lanes while chauffeurs cannot. And yes, that makes a huge difference in terms of when you arrive, often by a factor of two in Dublin.

Taxis, in general, take forever to arrive to pick you up. Plan for extra time. They are often a half hour late due to traffic.

Public busses, especially in the morning and evening peak hours are often full, meaning you may not be able to board and will have to wait for the next bus. If you take public transportation, have exact change ready.

Bus schedules are merely suggestions. Be prepared to wait for up to half an hour, standing, in whatever weather is occurring.

Locations

Ireland is not handicapped accessible like we are used to in the US. Many if not most restrooms are either upstairs or downstairs in restaurants and few have elevators, called lifts. Many public buildings don’t have public restrooms and will send you across the street or down the block for a restroom.

Tipping

People that Americans would typically tip, such as servers in restaurants, are paid differently and they don’t expect a tip. Some people round up to the nearest Euro. Tipping is neither necessary or expected.

As an American, it’s very difficult for me not to tip.

Money

Ireland uses the Euro, but Northern Ireland uses the English sterling pound. And no, they don’t take each other’s money.

Not everyplace accepts credit cards. Some taxis do, but be prepared to pay an uplift of about 4% for the privilege. And the card reader doesn’t always work. Have cash available.

Almost no businesses accept American Express.

Notify your credit card companies that you will be traveling, and when. I have also put free alerts on my cards so that I know when they are being used.

Restaurants and Food

Most restaurants won’t split bills between people. That’s your problem.

Some restaurants add a fee for large parties. Large is defined by the restaurant and they may not tell you in advance.

Service EVERYPLACE is slow. Some excruciatingly slow. Plan on dinner taking literally all evening. It’s normal and part of the Irish experience.

Pub food is better than just about anyplace else.

Water served with meals is available if you ask, but doesn’t arrive automatically. It may or may not have ice.

Furthermore, ice is a precious commodity. In the hotel, only one ice machine was available for 6 floors and no ice bucket, just plastic cups stacked beside the ice dispenser.

Many restaurants, including pubs, don’t have mixed drinks, such as margaritas. They have well drinks, such as scotch and water, wine and beer. Want Kahlua? Nope, but everyone has Baileys Irish Cream – after all – it’s Ireland.

Guinness is the national beer. Drink Guinness, or at least try it. The locals say that you can ask for a couple drops of currant to sweeten the beer, but I liked it without. It tastes a bit roasty. When in Rome…or Ireland.

Carry-out is referred to as take-away. Not everyplace offers take-away.

In some parts of Europe, like the Netherlands, sharing food is frowned upon, but I didn’t notice anything like that in Ireland. Either that or they were too nice to tell me.

Bathrooms

Europeans do not use washcloths or facecloths. I purchased a pack at the dollar store at home and left them behind as I traveled. What else are you going to do with a wet washcloth?

There are often two flush buttons on the toilet. Generally, the small one is for little flushes and the larger one is when bigger flushing is needed. Yes, I had to ask Brian because it seemed that neither worked reliably.

And then sometimes, you find something like this.

If in doubt, just push buttons until you find one that achieves the desired effect.

Those funny things on the walls are towel warmers.

We could learn from the Irish!

Your appliances may turn on with a switch at the baseboard near the plug. Why? I have no idea, but plugs often don’t work if you don’t turn them on.

Rain

Rain is a fact of life in Ireland. It’s how the Emerald Isle stays Emerald. Be prepared. It may rain and be sunny 10 minutes later, or vice versa. Every. Single. Day.

Often, umbrellas are useless due to the wind. Mine turned inside out, making me look like some sort of confused ninja parachutist.

Geography

Ireland is an island and the lower 4/5th is the country of Ireland, also known as the Republic of Ireland.

Northern Ireland, created in 1921, although historically part of Ireland, is a different country today, ruled under the British monarchy and is part of the United Kingdom. There are no longer any border checkpoints between the two, but with Brexit, that might change. If you’re planning to travel between the two, be prepared in terms of currency and a passport.

Language

In Ireland, the official language is English, but many speak Gaelic. Because the English historically tried to exterminate the Gaelic language, when Ireland regained control of its own government, they included a clause in the constitution that everything in Ireland is offered in two languages – up to and including road and other signage.

However, their English is spoken with a very heavy Irish brogue which is both beautiful and frustrating. Like someone said, two people separated by a common language.

Pharmaceuticals

Medications like Dramamine and cold medicine, things we typically purchase over the counter are behind the counter at pharmacies in Europe, including Ireland. Pharmacies are typically not open past 5 PM and many not before sometime between 10 and noon.

Don’t assume you can pick up any medications at the convenience store, because you likely can’t. Not to mention, convenience stores are few and far between, so not convenient as we think of them. My hotel, even though expensive, did not have a shop – only two vending machines. Take what you might need, plus extra.

Hotels

Plugs in hotels are often not located conveniently to a nightstand, so either take a European conformant (based on the country you are visiting) extension cord or plan otherwise.

My hotel in Ireland did provide shampoo, but no conditioner and no washcloths. Take your own supplies, just in case.

Hotels rooms also do not generally include microwaves or refrigerators.

Expect to pay for parking at hotels.

Many hotels offer “Afternoon tea” or “High tea” which is an afternoon event that includes tea, biscuits (cookies) and small finger sandwiches. It’s an upper class social event, people often “dress,” and sit and talk. My hotel did not offer tea, the one across the street did, for 45 Euro. Another Dublin hotel at the upscale end charged 95 Euro. I think this is a case of if you need to ask how much, don’t go. I didn’t but I was told that I should have high tea at least once in my life.  Guess I’ll have to go back!

Here’s a link to more info about tea time.

No clock or alarm in the hotel room. My cell phone was probably more reliable anyway and I had to get up to turn the alarm off, since there were no plugs bedside.

Hotels and Climate Control

Most hotels and B&Bs don’t have air conditioning. Neither do other buildings including public buildings, so you’ll need to grin and bear it. It’s seldom beastly hot, but it can be very close and humid.

My hotel room had a lovely set of French doors and a balcony, permanently sealed shut. I also had two windows, only one of which would crank out about 2 inches. That’s not much to obtain any type of air movement within the room.

Heat in hotels, especially in older buildings is generally by radiator, not by thermostat, if heated at all. You will need to turn a knob on the radiator when entering the room to turn the heat on – and if you get too hot, there is no way to cool off. So be careful.

I stayed at the Clayton Ballsbridge, which I do NOT recommend for various reasons including consistently very poor service combined with an attitude that I was being unreasonable to expect decent service, like you know, clean cups, replenished tea, etc., daily, in my room that cost over $190 per night. Not to mention it took two and a half hours to get a bowl of stew in the restaurant.

Perhaps this is the down side to tipping being included in the price of the meal – little motivation for good service.

People staying in B&Bs were generally happier than people who stayed in hotels.

Electronics

You will need items that will plug in to 230 volt, 50 Hz power which have a different plug than in the US.

This is not necessarily just a converter issue, but a voltage compatibility issue. Check the voltage on your device.  In my case, a heating pad did not work using a converter, so I had to purchase one that would. Then I needed an extension cord, which I didn’t have. Plan accordingly.

You will need multiple converters so that you can charge your phone, etc. Here’s a page that discusses converters and sockets.

Plugs are often not placed conveniently.

Phones

OMG, the bane of my existence. Phones hate me, truly, and always have.

I can call Ireland from the US, but I cannot seem to call anyone in Ireland on my US cell phone while in Ireland, and I tried every combination I could think of and that anyone suggested. I suspect, but don’t know, that it had to do with a US phone being in Ireland, so it was confused by which type of country access code it needed. I could, however, message one person, thankfully. I never could manage to communicate with another.

Here’s my suggestion. Find someone in Ireland, maybe at the hotel front desk, that you can practice with. Once you figure out what you need to do on your phone to call them, it should work when dialing others in country too.

Beware of cell phone roaming and data charges. Understand how to turn off roaming by putting your phone in airplane mode. Before traveling, call or visit your phone carrier and understand what you can and cannot do with what kind of data without being charged. It’s extremely easy to run up a cell bill over $1000 and never realize what is happening. Case in point, your phone is always roaming to update Facebook and similar apps.

Mind you, I couldn’t make a bloody call, but the phone found ways to connect so that I’d be charged!

Tours

Unless you arrange for a private tour, which I did with Brian, tours generally leave from the downtown area at the beginning of the day, which means you’re going to encounter heavy rush hour traffic getting to the tour site. Allow adequate time, more than you think you’ll ever need, because the tour will leave without you otherwise.

Private tours cost more, especially for one person, but by the time you have 3 or 4 people or so, depending on the tour, the cumulative cost won’t be more and you’ll be much MUCH happier. Plus, a private tour can cater to your desires – like a coffee break, bathroom stop, a quilt shop along the way, or anything else of interest.

Seasons and Stores

Some businesses are seasonal – including restaurants. If you are not visiting in the high tourist season of June-August, I would strongly suggest calling ahead if you are planning on visiting a particular location.

Small businesses may or may not be open on a whim. Seriously. Always call.

Genealogy and Research Assistance

I asked these fine folks, shown here on a day trip in front of Carrickfergus Castle in Belfast, about their recommendations for Irish genealogical research:

  • Michelle Leonard, professional genealogist at Genes & Genealogy, out of Glasgow, Scotland (red hair, above)
  • Martin McDowell, professional genealogist (martin.mcdowell3@talktalk.net) as well as Development and Education Director with The North of Ireland Family History Society (right, above)
  • Dr. Maurice Gleeson, coordinator of Genetic Genealogy Ireland (left, above)

These people work with Irish records, as well as genetic genealogy every day, and they know what they are doing.

Martin recommends https://www.irishgenealogy.ie/en/ where both church and civil records can be found free of charge. He suggests that of the best pay sites for Irish records is http://www.rootsireland.ie/, though its accuracy depends on the quality of the transcription.

The North of Ireland Family History Society where Martin serves as the Education & Development Officer provides a website detailing their holdings: http://www.nifhs.org/, including a full PDF of everything in the library: http://www.nifhs.org/library-list/

Maurice mentions that the PRONI and GRONI sites are specifically Northern Ireland:

Michelle points out that irishgenealogy.ie has all of the Northern Ireland BMDs prior to January 1, 1922. She points out that if you’re searching for a marriage that took place in 1906, search for it on irishgenealogy.ie where you will get the image for free as opposed to on GRONI where it will cost you £2.50 for the same image.  On the other hand if you’re searching for a marriage that took place prior to 1882 in Northern Ireland you will find it on irishgenealogy.ie but there will be no image so it’s best to go to GRONI and pay the £2.50.

My personal experience is more limited, being only a consumer of Irish research, not a professional researcher. Having said that, I DON’T recommend the Ulster Historical Foundation. I completed their form and requested an initial assessment for 35 pounds sterling on July 4th, and I’m still waiting to hear back, today, many months later, after my trip to Ireland is complete. They could at least have told me they were too busy to accommodate my needs.

The web site says they are extremely busy and to expect a delay of 4-6 weeks, but never contacting the person requesting the research is unacceptable.  It’s a good thing I was able to find a private researcher (Martin McDowell) who was willing to take an “emergency” case at a late date. Unfortunately, my situation because “an emergency” because I waited for the Ulster Historical Foundation, expecting they would be able to assist my research. Thank you Martin McDowell for being my hero and Maurice Gleeson for helping me find Martin!

I do recommend the Irish Folklore Center as well as John Grenham’s blog and website.  To find where surnames are clustered in Ireland, a surname map which combines information from 1848 through the 1911 census is available here.

For genetic genealogy, I strongly suggest the videos produced at Genetic Genealogy Ireland which now form a library on the GGI YouTube channel, all for free. Also, the ISOGG Ireland page provides an extensive list of Ireland specific resources.

By the way, a big thank you to all of the volunteers, including the speakers, who work together to produce Genetic Genealogy Ireland. GGI is an all-volunteer effort, and without these people, and Maurice Gleeson coordinating the entire event, it wouldn’t happen!

You might want to attend the Belfast Genetic Genealogy Ireland Conference on February 17-18 sponsored by Family Tree DNA. You can read more here including the great lineup of 13 free sessions and speakers focused on genetic genealogy!

Safety

As big cities go, I felt safe in Dublin and Belfast, or as safe as I feel in any large city, although I was never in the Belfast city center. I felt a lot better having Brian with me, directing me and explaining what I should and should not do and where I shouldn’t go, and why.

Time

I intended to visit six locations:

  • Dublin
  • The Cliffs of Moher
  • Giant’s Causeway
  • Wicklow Mountains
  • Boyne Valley – Knowth, New Grange and Tara
  • Belfast

Partly due to the hurricane, and partly due to fatigue, I scrapped the Cliffs and Giant’s Causeway trips.

Those two trips are long, meaning 12 hour days and that doesn’t include dinner. They are difficult in the rain and when it stays dark later in the morning and gets dark early in the evening. Those trips, in addition to the 8 hour days for the other trips, were just too much, on back to back days.

If I had planned for an additional 3 or 4 days in Ireland, it would have given me the opportunity to rest between tours or see a few additional sights in Dublin on the down days.

Even with that consideration, the late fall is not the best time of year for visits to either the Giant’s Causeway or the Cliffs of Moher from Dublin.

Ireland is Wonderful

Go.

Enjoy.

Eat pub food.

Drink Guinness.

Connect with your roots!

If you need to test your DNA before you go, I recommend Family Tree DNA for Y (patrilineal for men) and mitochondrial (matrilineal for both genders) DNA testing, as well as Family Finder autosomal for cousin matching across all of your genealogy. If you would like to know more about these various types of tests, please read 4 Kinds of DNA for Genetic Genealogy.

In my case, I could not personally test for the Y DNA of my McDowell ancestor – so I found a McDowell male from my line to take that test. Were it not for his results that included a match to a man who knew exactly where the McDowell’s lived in Ireland, I would never have known where my McDowell line originated and been able to visit and traverse the road where they lived. So think in terms of testing appropriate relatives to unlock secrets about your ancestors!

2018 Resolution – Unveiling Hidden Evidence

I spent New Year’s Eve, doing what I’ve done for years on New Year’s Eve – celebrating by researching. In fact, it was at the stroke of midnight in 2005 that I ordered kit number 50,000 from Family Tree DNA.  Yes, I’m just that geeky and yes, I had to purchase several kits in a row to get number 50,000.

That kit went on to help immensely, as I used it to test an elderly cousin of my great-grandmother’s generation who took both the Y DNA test, and then, eventually, autosomal.

This year I made a wonderful discovery to mark the new year.  But first, let’s see how I did with last year’s resolution.

Last Year’s Resolution

Last year, I made 1 resolution. Just one – to complete another year’s worth of 52 Ancestor stories.

Now, that didn’t mean I had to do 52 in total.  It meant I had to be committed to this project throughout the year.  You know, unlike cleaning out that closet…or losing weight…or exercising more. Commitments that are abandoned almost as soon as they are made.

So, how did I do?

I published 37 stories.  I shudder to think how many words or even pages that was.  I’m ashamed to say that I plucked much of the “low hanging fruit” early on, so these were tough ancestors for an entire variety of reasons.

That’s not one article each week, but at least I’m making steady progress. And I must say that I couldn’t do it without a raft of helpers – all of whom I’m exceedingly grateful to.  Friends, professionals, cousins, DNA testers, blog subscribers and commenters – an unbelievable array of very kind souls who are willing to give of their time and share their results. Thank you each and every one!

Now, I’m thrilled to tell you that Amy Johnson Crow has revitalized the 52 Ancestor’s project.  It’s free and you can sign up here.  There’s no obligation, but Amy provides suggestions and a “gathering place” of sorts. Think of her as your genealogy cheerleader or coach. It’s so much easier with friends and teammates! I miss reading other people’s stories, but I won’t have to miss that much longer!

Randy Seaver (of Genea-Musings) and I will have company once again.  He’s the only other person that I’m aware of that has continued the 52 Ancestors project – and he has put me way to shame.  I do believe he published number 286 this week.  I keep hoping that some of his ancestors and some of mine are the same so I can piggyback on Randy’s research! I need an index! Randy, are you listening?

You might wonder why I enjoy this self-imposed deadline ancestor-writing so much.

It’s really quite simple.  It’s an incredible way to organize and sort through all of your accumulated research “stuff.”  I cherish the end product – documenting my ancestors lives with dates, compassion and history.  BUT, I absolutely hate parts of the research process – and the deadline (of sorts) gets me through those knotholes.

I absolutely love the DNA, and I really, REALLY like the feeling of breaking through brick walls.  It’s like I’m vindicating my ancestors and saving them from the eternal cutting room floor. DNA is an incredible tool to do just that and there are very few ancestors that I can’t learn something from their DNA, one way or another – Y, mtDNA,  autosomal and sometimes, all three.  And yes, DNA is in every one of my articles, one way or another. I want everyone to learn how to utilize DNA in the stories of their ancestor’s lives.  In many cases the DNA of theirs that we (and our cousins) carry is the only tangible thing left of them. We are wakling historical museums of our ancestral lines!

How Did You Do?

Not to bring up an awkward subject, but if you recall, I asked you if you had any genealogy resolutions for 2017?  How did you do?

Congratulations if you succeeded or made progress.

It’s OK if you didn’t quite make it. Don’t sweat last year.  It’s over and 2018 is a brand spanking new year.

New Year Equals New Opportunities

2018 is stacking up to be a wonderful year. There are already new matches arriving daily due to the Black Friday sales and that’s only going to get better in the next month or two.  Of course, that’s something wonderful to look forward to in the dead of winter.  We’ll just call this my own personal form of hibernating. Could I really get away with not leaving my house for an entire month? Hmmm….

I want to give you three ideas for having some quick wins that will help you feel really great about your genealogy this year.

Idea 1 – Finding Hidden Mitochondrial DNA

This happened to me just last night and distracted me so badly that I actually was late to wish everyone a Happy New Year.  Yes, seriously.  One of my friends told me this is the best excuse ever!

I was working on making a combined tree for the descendants of an ancestor who have tested and I suddenly noticed that one of the female autosomal matches descended from the female of the ancestral couple through all females – which means my match carries my ancestor’s mitochondrial DNA!

Woohooooooo – it’s a wonderful day.

Better yet, my match tested at Family Tree DNA AND had already taken the mitochondrial DNA test.

Within about 60 seconds of noticing her pattern of descent, I had the haplogroup of our common ancestor. That’s the BEST New Year’s gift EVER.  I couldn’t sleep last night.

So, know what I did instead of sleeping? I bet you can guess!

Yes indeed, I started searching through my matches at Family Tree DNA for other people descended from female ancestors whose mtDNA I don’t have!

So, my first challenge to you is to do the same.

Utilizing Family Finder, enter the surname you’re searching for into the search box in the upper right hand corner of your matches page.

That search will produce individuals who have that surname included in their list of ancestral surnames or who carry that surname themselves.

Your tree feeds the ancestral surname list with all of the surnames in your tree.  I understand this will be changing in the future to reflect only your direct line ancestral surnames.

Some people include locations with their surnames – so you may recognize your line that way. Click on your match’s surname list (at far right) to show their entire list of surnames in a popup box. Some lists are very long.  I selected the example below because it’s short.

Your common surnames are bolded and float to the top.  The name you are searching for will be blue, so it’s easy to see, especially in long lists of surnames. 

About half of my matches at Family Tree DNA have trees.  Click on the pedigree icon and then search for your surname of interest in your match’s tree.

Hey, there’s our common ancestral couple – William George Estes and Ollie Bolton!!!

Idea 2 – Finding Hidden Y DNA

Now that I’ve shown you how to find hidden mitochondrial DNA, finding hidden Y DNA is easy.  Right?

You know what to do.

I this case, you’ll be looking for a male candidate who carries the surname of the line you are seeking, which is very easy to spot on the match list.

Now, word of warning.

As bizarre as this sounds, not all men who carry that surname and match autosomally are from the same genetic surname line.

As I was working with building a community tree for my matches last night, I was excited to see that one of my cousins (whose kit I manage) matches a man with the Herrell surname.

I quickly clicked on the match’s tree to see which Herrell male the match descends from, only to discover that he didn’t descend from my Herrell line.

Whoa – you’re saying – hold on, because maybe my line is misidentified.  And I’d agree with you – except in this case, I have the Y DNA signature of both lines – because at one time I thought they were one and the same. You can view the Herrell Y DNA project here.  My family line is Harrold Line 7.

Sure enough, through the Family Finder match, I checked my Harrell match’s profile and his haplogroup is NOT the same as my Herrell haplogroup (I-P37.)

I could have easily been led astray by the same surname. I really don’t need to know any more about his Y DNA at this point, because the completely different haplogroup is enough to rule out a common paternal line.

Don’t let yourself get so excited that you forget to be a skeptical genealogist😊

My second challenge to you is to hunt for hidden Y DNA.

You can  increase your chances of finding your particular lineage by visiting the relevant Y DNA projects for your surname.

Click on Projects, then “Join a project,” then search for the DNA project that you’re interested in viewing and click on that link.

Within the project, look for oldest ancestors that are your ancestors, or potentially from a common location.  It’s someplace to start.

Idea 3 – Pick A Puzzle Piece

Sometimes we get overwhelmed with the magnitude and size of the genealogy puzzle we’d like to solve. Then, we don’t solve anything.

This is exactly WHY I like the 52 Ancestor stories.  They make me focus on JUST ONE ancestor at a time.

So, for 2018, pick one genealogy puzzle you’d really like to solve. One person or one thing.  Not an entire line.

Write down your goal.

“I’d like to figure out whether John Doe was the son of William Doe or his son, Alexander Doe.”

Now admittedly, this is a tough one, because right off the bat, Y DNA isn’t going to help you unless you’re incredibly lucky and there is a mutation between Alexander Doe and his father, William.  If indeed that was the case, and you can prove it by the DNA of two of Alexander’s sons who carry the mutation, compared to the DNA of one of William’s other sons who does not, then you may be cooking with gas, presuming you can find a male Doe descended from John to test as well.

This is the type of thought process you’ll need to step through when considering all of the various options for how to prove, or disprove, a particular theory.

Make a list of the different kinds of evidence, both paper trail and genetic, that you could use to shed light on the problem. Your answer may not come from one piece of evidence alone, but a combination of several.

Evidence Available/Source Result
William’s will No, burned courthouse Verified
Alexander’s will No, burned courthouse Verified
Deeds with William as conveyor No, burned courthouse Verified
Family Bible Nope, no Bible
Deeds with Alexander as conveyor, naming John Possible, some deed books escaped fire Check through county, Family search does not list
Deeds with John as conveyor Yes, check to see if they indicate the source of John’s land John is listed in index, need to obtain original deeds from county
Y DNA of John’s line Yes, has been tested Matches DNA of William’s line as proven through William’s two brothers
Y DNA of Alexander Not tested (to the best of my knowledge), find descendant to see if they will test Search vendor DNA testing sites for male with this surname to see if they have/will Y DNA test
Closeness (in total cM and longest segment) of individuals autosomal matching through any of William’s descendants Mine both Ancestry and FTDNA for surname and ancestor matches This step may produce compelling or suggestive evidence, and it may not.  Make a McGuire chart of results.
Does John match any relatives of the wife of Alexander Doe? Search FTDNA and Ancestry for matches.  Triangulate to determine if match is valid and through that line. This is one of the best approaches to solve this type of problem when paper records aren’t available. Fingers crossed that Alexander and his wife and not related.

You can add pieces of evidence to your list as you think of them.

Making a list gives you something to work towards.

Your Turn!

Select one thing that you’d like to accomplish and either set about to do it, like mining for mitochondrial or Y DNA evidence, or put together a plan to gather evidence, both traditional and genetic.

In the comments, share what it is you’ll be searching for or working on.  You just never know if another subscriber may hold the answer you seek.

I can’t wait to hear what you’ll be doing this year!

Have a wonderful and productive New Year searching for those hidden ancestors!

2017 – The Year of DNA

Every year for the past 17 years has been the year of DNA for me, but for many millions, 2017 has been the year of DNA. DNA testing has become a phenomenon in its own right.

It was in 2013 that Spencer Wells predicted that 2014 would be the “year of infection.” Spencer was right and in 2014 DNA joined the ranks of household words. I saw DNA in ads that year, for the first time, not related to DNA testing or health as in, “It’s in our DNA.”

In 2014, it seemed like most people had heard of DNA, even if they weren’t all testing yet. John Q. Public was becoming comfortable with DNA.

In 2017 – DNA Is Mainstream  

If you’re a genealogist, you certainly know about DNA testing, and you’re behind the times if you haven’t tested.  DNA testing is now an expected tool for genealogists, and part of a comprehensive proof statement that meets the genealogical proof standard which includes “a reasonably exhaustive search.”  If you haven’t applied DNA, you haven’t done a reasonably exhaustive search.

A paper trail is no longer sufficient alone.

When I used to speak to genealogy groups about DNA testing, back in the dark ages, in the early 2000s, and I asked how many had tested, a few would raise their hands – on a good day.

In October, when I asked that same question in Ireland, more than half the room raised their hand – and I hope the other half went right out and purchased DNA test kits!

Consequently, because the rabid genealogical market is now pretty much saturated, the DNA testing companies needed to find a way to attract new customers, and they have.

2017 – The Year of Ethnicity

I’m not positive that the methodology some of the major companies utilized to attract new consumers is ideal, but nonetheless, advertising has attracted many new people to genetic genealogy through ethnicity testing.

If you’re a seasoned genetic genealogist, I know for sure that you’re groaning now, because the questions that are asked by disappointed testers AFTER the results come back and aren’t what people expected find their way to the forums that genetic genealogists peruse daily.

I wish those testers would have searched out those forums, or read my comparative article about ethnicity tests and which one is “best” before they tested.

More ethnicity results are available from vendors and third parties alike – just about every place you look it seems.  It appears that lots of folks think ethnicity testing is a shortcut to instant genealogy. Spit, mail, wait and voila – but there is no shortcut.  Since most people don’t realize that until after they test, ethnicity testing is becoming ever more popular with more vendors emerging.

In the spring, LivingDNA began delivering ethnicity results and a few months later, MyHeritage as well.  Ethnicity is hot and companies are seizing a revenue opportunity.

Now, the good news is that perhaps some of these new ethnicity testers can be converted into genealogists.  We just have to view ethnicity testing as tempting bait, or hopefully, a gateway drug…

2017 – The Year of Explosive Growth

DNA testing has become that snowball rolling downhill that morphed into an avalanche.  More people are seeing commercials, more people are testing, and people are talking to friends and co-workers at the water cooler who decide to test. I passed a table of diners in Germany in July to overhear, in English, discussion about ethnicity-focused DNA testing.

If you haven’t heard of DTC, direct to consumer, DNA testing, you’re living under a rock or maybe in a third world country without either internet or TV.

Most of the genetic genealogy companies are fairly closed-lipped about their data base size of DNA testers, but Ancestry isn’t.  They have gone from about 2 million near the end of 2016 to 5 million in August 2017 to at least 7 million now.  They haven’t said for sure, but extrapolating from what they have said, I feel safe with 7 million as a LOW estimate and possibly as many as 10 million following the holiday sales.

Advertising obviously pays off.

MyHeritage recently announced that their data base has reached 1 million, with only about 20% of those being transfers.

Based on the industry rumble, I suspect that the other DNA testing companies have had banner years as well.

The good news is that all of these new testers means that anyone who has tested at any of the major vendors is going to get lots of matches soon. Santa, it seems, has heard about DNA testing too and test kits fit into stockings!

That’s even better news for all of us who are in multiple data bases – and even more reason to test at all of the 4 major companies who provide DNA matching for their customers: Family Tree DNA, Ancestry, MyHeritage and 23andMe.

2017 – The Year of Vendor and Industry Churn

So much happened in 2017, it’s difficult to keep up.

  • MyHeritage entered the DNA testing arena and began matching in September of 2016. Frankly, they had a mess, but they have been working in 2017 to improve the situation.  Let’s just say they still have some work to do, but at least they acknowledge that and are making progress.
  • MyHeritage has a rather extensive user base in Europe. Because of their European draw, their records collections and the ability to transfer results into their data base, they have become the 4th vendor in a field that used to be 3.
  • In March 2017, Family Tree DNA announced that they were accepting transfers of both the Ancestry V2 test, in place since May of 2016, along with the 23andMe V4 test, available since November 2013, for free. MyHeritage has since been added to that list. The Family Tree DNA announcement provided testers with another avenue for matching and advanced tools.
  • Illumina obsoleted their OmniExpress chip, forcing vendors to Illumina’s new GSA chip which also forces vendors to use imputation. I swear, imputation is a swear word. Illumina gets the lump of coal award for 2017.
  • I wrote about imputation here, but in a nutshell, the vendors are now being forced to test only about 20% of the DNA locations available on the previous Illumina chip, and impute or infer using statistics the values in the rest of the DNA locations that they previously could test.
  • Early imputation implementers include LivingDNA (ethnicity only), MyHeritage (to equalize the locations of various vendor’s different chips), DNA.Land (whose matching is far from ideal) and 23andMe, who seems, for the most part, to have done a reasonable job. Of course, the only way to tell for sure at 23andMe is to test again on the V5 chip and compare to V3 and V4 chip matches. Given that I’ve already paid 3 times to test myself at 23andMe (V2, 3 and 4), I’m not keen on paying a 4th time for the V5 version.
  • 23andMe moved to the V5 Illumina GSA chip in August which is not compatible with any earlier chip versions.
  • Needless to say, the Illumina chip change has forced vendors away from focusing on new products in order to develop imputation code in order to remain backwards compatible with their own products from an earlier chip set.
  • GedMatch introduced their sandbox area, Genesis, where people can upload files that are not compatible with the traditional vendor files.  This includes the GSA chip results (23andMe V5,) exome tests and others.  The purpose of the sandbox is so that GedMatch can figure out how to work with these files that aren’t compatible with the typical autosomal test files.  The process has been interesting and enlightening, but people either don’t understand or forget that it’s a sandbox, an experiment, for all involved – including GedMatch.  Welcome to living on the genetic frontier!

  • I assembled a chart of who loves who – meaning which vendors accept transfers from which other vendors.

  • I suspect but don’t know that Ancestry is doing some form of imputation between their V1 and V2 chips. About a month before their new chip implementation in May of 2016, Ancestry made a change in their matching routine that resulting in a significant shift in people’s matches.

Because of Ancestry’s use of the Timber algorithm to downweight some segments and strip out others altogether, it’s difficult to understand where matching issues may arise.  Furthermore, there is no way to know that there are matching issues unless you and another individual have transferred results to either Family Tree DNA or GedMatch, neither of which remove any matching segments.

  • Other developments of note include the fact that Family Tree DNA moved to mitochondrial DNA build V17 and updated their Y DNA to hg38 of the human reference genome – both huge undertakings requiring the reprocessing of customer data. Think of both of those updates as housekeeping. No one wants to do it, but it’s necessary.
  • 23andMe FINALLY finished transferring their customer base to the “New Experience,” but many of the older features we liked are now gone. However, customers can now opt in to open matching, which is a definite improvement. 23andMe, having been the first company to enter the genetic genealogy autosomal matching marketspace has really become lackluster.  They could have owned this space but chose not to focus on genealogy tools.  In my opinion, they are now relegated to fourth place out of a field of 4.
  • Ancestry has updated their Genetic Communities feature a couple of times this year. Genetic Communities is interesting and more helpful than ethnicity estimates, but neither are nearly as helpful as a chromosome browser would be.

  • I’m sure that the repeated requests, begging and community level tantrum throwing in an attempt to convince Ancestry to produce a chromosome browser is beyond beating a dead horse now. That dead horse is now skeletal, and no sign of a chromosome browser. Sigh:(
  • The good news is that anyone who wants a chromosome browser can transfer their results to Family Tree DNA or GedMatch (both for free) and utilize a chromosome browser and other tools at either or both of those locations. Family Tree DNA charges a one time $19 fee to access their advanced tools and GedMatch offers a monthly $10 subscription. Both are absolutely worth every dime. The bad news is, of course, that you have to convince your match or matches to transfer as well.
  • If you can convince your matches to transfer to (or test at) Family Tree DNA, their tools include phased Family Matching which utilizes a combination of user trees, the DNA of the tester combined with the DNA of family matches to indicate to the user which side, maternal or paternal (or both), a particular match stems from.

  • Sites to keep your eye on include Jonny Perl’s tools which include DNAPainter, as well as Goran Rundfeldt’s DNA Genealogy Experiment.  You may recall that in October Goran brought us the fantastic Triangulator tool to use with Family Tree DNA results.  A few community members expressed concern about triangulation relative to privacy, so the tool has been (I hope only temporarily) disabled as the involved parties work through the details. We need Goran’s triangulation tool! Goran has developed other world class tools as well, as you can see from his website, and I hope we see more of both Goran and Jonny in 2018.
  • In 2017, a number of new “free” sites that encourage you to upload your DNA have sprung up. My advice – remember, there really is no such thing as a free lunch.  Ask yourself why, what’s in it for them.  Review ALL OF THE documents and fine print relative to safety, privacy and what is going to be done with your DNA.  Think about what recourse you might or might not have. Why would you trust them?

My rule of thumb, if the company is outside of the US, I’m immediately slightly hesitant because they don’t fall under US laws. If they are outside of Europe or Canada, I’m even more hesitant.  If the company is associated with a country that is unfriendly to the US, I unequivocally refuse.  For example, riddle me this – what happens if a Chinese (or fill-in-the-blank country) company violates an agreement regarding your DNA and privacy?  What, exactly, are you going to do about it from wherever you live?

2017 – The Year of Marketplace Apps

Third party genetics apps are emerging and are beginning to make an impact.

GedMatch, as always, has continued to quietly add to their offerings for genetic genealogists, as had DNAGedcom.com. While these two aren’t exactly an “app”, per se, they are certainly primary players in the third party space. I use both and will be publishing an article early in 2018 about a very useful tool at DNAGedcom.

Another application that I don’t use due to the complex setup (which I’ve now tried twice and abandoned) is Genome Mate Pro which coordinates your autosomal results from multiple vendors.  Some people love this program.  I’ll try, again, in 2018 and see if I can make it all the way through the setup process.

The real news here are the new marketplace apps based on Exome testing.

Helix and their partners offer a number of apps that may be of interest for consumers.  Helix began offering a “test once, buy often” marketplace model where the consumer pays a nominal price for exome sequencing ($80), significantly under market pricing ($500), but then the consumer purchases DNA apps through the Helix store. The apps access the original DNA test to produce results. The consumer does NOT receive their downloadable raw data, only data through the apps, which is a departure from the expected norm. Then again, the consumer pays a drastically reduced price and downloadable exome results are available elsewhere for full price.

The Helix concept is that lots of apps will be developed, meaning that you, the consumer, will be interested and purchase often – allowing Helix to recoup their sequencing investment over time.

Looking at the Helix apps that are currently available, I’ve purchased all of the Insitome products released to date (Neanderthal, Regional Ancestry and Metabolism), because I have faith in Spencer Wells and truthfully, I was curious and they are reasonably priced.

Aside from the Insitome apps, I think that the personalized clothes are cute, if extremely overpriced. But what the heck, they’re fun and raise awareness of DNA testing – a good thing! After all, who am I to talk, I’ve made DNA quilts and have DNA clothing too.

Having said that, I’m extremely skeptical about some of the other apps, like “Wine Explorer.”  Seriously???

But then again, if you named an app “I Have More Money Than Brains,” it probably wouldn’t sell well.

Other apps, like Ancestry’s WeRelate (available for smartphones) is entertaining, but is also unfortunately EXTREMELY misleading.  WeRelate conflates multiple trees, generally incorrectly, to suggest to you and another person on your Facebook friends list are related, or that you are related to famous people.  Judy Russell reviews that app here in the article, “No, actually, we’re not related.” No.  Just no!

I feel strongly that companies that utilize our genetic data for anything have a moral responsibility for accuracy, and the WeRelate app clearly does NOT make the grade, and Ancestry knows that.  I really don’t believe that entertaining customers with half-truths (or less) is more important than accuracy – but then again, here I go just being an old-fashioned fuddy dud expecting ethics.

And then, there’s the snake oil.  You knew it was going to happen because there is always someone who can be convinced to purchase just about anything. Think midnight infomercials. The problem is that many consumers really don’t know how to tell snake oil from the rest in the emerging DNA field.

You can now purchase DNA testing for almost anything.  Dating, diet, exercise, your taste in wine and of course, vitamins and supplements. If you can think of an opportunity, someone will dream up a test.

How many of these are legitimate or valid?  Your guess is as good as mine, but I’m exceedingly suspicious of a great many, especially those where I can find no legitimate scientific studies to back what appear to be rather outrageous claims.

My main concern is that the entire DTC testing industry will be tarred by the brush of a few unethical opportunists.

2017 – The Year of Focus on Privacy and Security

With increased consumer exposure comes increased notoriety. People are taking notice of DNA testing and it seems that everyone has an opinion, informed or not.  There’s an old saying in marketing; “Talk about me good, talk about me bad, just talk about me.”

With all of the ads have come a commensurate amount of teeth gnashing and “the-sky-is-falling” type reporting.  Unfortunately, many politicians don’t understand this industry and open mouth only to insert foot – except that most people don’t realize what they’ve done.  I doubt that the politicians even understand that they are tasting toe-jam, because they haven’t taken the time to research and understand the industry. Sound bites and science don’t mix well.

The bad news is that next, the click-bait-focused press picks up on the stories and the next time you see anyone at lunch, they’re asking you if what they heard is true.  Or, let’s hope that they ask you instead of just accepting what they heard as gospel. Hopefully if we’ve learned anything in this past year, it’s to verify, verify, verify.

I’ve been an advocate for a very long time of increased transparency from the testing companies as to what is actually done with our DNA, and under what circumstances.  In other words, I want to know where my DNA is and what it’s being used for.  Period.

Family Tree DNA answered that question succinctly and unquestionably in December.

Bennett Greenspan: “We could probably make a lot of money by selling the DNA data that we’ve been collecting over the years, but we feel that the only person that should have your DNA information is you.  We don’t believe that it should be sold, traded or bartered.”

You can’t get more definitive than that.

DTC testing for genetic genealogy must be a self-regulating field, because the last thing we need is for the government to get involved, attempting to regulate something they don’t understand.  I truly believe government interference by the name of regulation would spell the end of genetic genealogy as we know it today.  DNA testing for genetic genealogy without sharing results is entirely pointless.

I’ve written about this topic in the past, but an update is warranted and I’ll be doing that sometime after the first of the year.  Mostly, I just need to be able to stay awake while slogging through the required reading (at some vendor sites) of page after page AFTER PAGE of legalese😊

Consumers really shouldn’t have to do that, and if they do, a short, concise summary should be presented to them BEFORE they purchase so that they can make a truly informed decision.

Stay tuned on this one.

2017 – The Year of Education

The fantastic news is that with all of the new people testing, a huge, HUGE need for education exists.  Even if 75% of the people who test don’t do anything with their results after that first peek, that still leaves a few million who are new to this field, want to engage and need some level of education.

In that vein, seminars are available through several groups and institutes, in person and online.  Almost all of the leadership in this industry is involved in some educational capacity.

In addition to agendas focused on genetic genealogy and utilizing DNA personally, almost every genealogy conference now includes a significant number of sessions on DNA methods and tools. I remember the days when we were lucky to be allowed one session on the agenda, and then generally not without begging!

When considering both DNA testing and education, one needs to think about the goal.  All customer goals are not the same, and neither are the approaches necessary to answer their questions in a relevant way.

New testers to the field fall into three primary groups today, and their educational needs are really quite different, because their goals, tools and approaches needed to reach those goals are different too.

Adoptees and genealogists employ two vastly different approaches utilizing a common tool, DNA, but for almost opposite purposes.  Adoptees wish to utilize tests and trees to come forward in time to identify either currently living or recently living people while genealogists are interested in reaching backward in time to confirm or identify long dead ancestors. Those are really very different goals.

I’ve illustrated this in the graphic above.  The tester in question uses their blue first cousin match to identify their unknown parent through the blue match’s known lineage, moving forward in time to identify the tester’s parent.  In this case, the grandparent is known to the blue match, but not to the yellow tester. Identifying the grandparent through the blue match is the needed lynchpin clue to identify the unknown parent.

The yellow tester who already knows their maternal parent utilizes their peach second cousin match to verify or maybe identify their maternal great-grandmother who is already known to the peach match, moving backwards in time. Two different goals, same DNA test.

The three types of testers are:

  • Curious ethnicity testers who may not even realize that at least some of the vendors offer matching and other tools and services.
  • Genealogists who use close relatives to prove which sides of trees matches come from, and to triangulate matching segments to specific ancestors. In other words, working from the present back in time. The peach match and line above.
  • Adoptees and parent searches where testers hope to find a parent or siblings, but failing that, close relatives whose trees overlap with each other – pointing to a descendant as a candidate for a parent. These people work forward in time and aren’t interested in triangulation or proving ancestors and really don’t care about any of those types of tools, at least not until they identify their parent.  This is the blue match above.

What these various groups of testers want and need, and therefore their priorities are different in terms of their recommendations and comments in online forums and their input to vendors. Therefore, you find Facebook groups dedicated to Adoptees, for example, but you also find adoptees in more general genetic genealogy groups where genealogists are sometimes surprised when people focused on parent searches downplay or dismiss tools such as Y DNA, mitochondrial DNA and chromosome browsers that form the bedrock foundation of what genealogists need and require.

Fortunately, there’s room for everyone in this emerging field.

The great news is that educational opportunities are abundant now. I’m listing a few of the educational opportunities for all three groups of testers, in addition to my blog of course.😊

Remember that this blog is fully searchable by keyword or phrase in the little search box in the upper right hand corner.  I see so many questions online that I’ve already answered!

Please feel free to share links of my blog postings with anyone who might benefit!

2018 – What’s Ahead? 

About midyear 2018, this blog will reach 1000 published articles. This is article number 939.  That’s amazing even to me!  When I created this blog in July of 2012, I wasn’t sure I’d have enough to write about.  That certainly has changed.

Beginning shortly, the tsunami of kits that were purchased during the holidays will begin producing matches, be it through DNA upgrades at Family Tree DNA, Big Y tests which were hot at year end, or new purchases through any of the vendors.  I can hardly wait, and I have my list of brick walls that need to fall.

Family Tree DNA will be providing additional STR markers extracted from the Big Y test. These won’t replace any of the 111 markers offered separately today, because the extraction through NGS testing is not as reliable as direct STR testing for those markers, but the Big Y will offer genealogists a few hundred more STRs to utilize. Yes, I said a few hundred. The exact number has not yet been finalized.

Family Tree DNA says they will also be introducing new “qualify of life improvements” along with new privacy and consent settings.  Let’s hope this means new features and tools will be released too.

MyHeritage says that they are introducing new “Discoveries” pages and a chromosome browser in January.  They have also indicated that they are working on their matching issues.  The chromosome browser is particularly good news, but matching must work accurately or the chromosome browser will show erroneous information.  Let’s hope January brings all three features.

LivingDNA indicates that they will be introducing matching in 2018.

2018 – What Can You Do?

What can you do in 2018 to improve your odds of solving genealogy questions?

  • Test relatives
  • Transfer your results to as many data bases as possible (among the ones discussed above, after reading the terms and conditions, of course)
  • If you have transferred a version of your DNA that does not produce full results, such as the Ancestry V2 or 23andMe V4 test to Family Tree DNA, consider testing on the vendor’s own chip in order to obtain all matches, not just the closest matches available from an incompatible test transfer.
  • Test Y and mitochondrial DNA at Family Tree DNA.
  • Find ways to share the stories of your ancestors.  Stories are cousin bait.  My 52 Ancestors series is living proof.  People find the stories and often have additional facts, information or even photos. Some contacts qualify for DNA testing for Y or mtDNA lines. The GREAT NEWS is that Amy Johnson Crow is resuming the #52Ancestors project for 2018, providing hints and tips each week! Who knows what you might discover by sharing?! Here’s how to start a blog if you need some assistance.  It’s easy – really!
  • Focus on the brick walls that you want to crumble and then put together both a test and analysis plan. That plan could include such things as:

o   Find out if a male representing a Y line in your tree has tested, and if not, search through autosomal results to see if a male from that paternal surname line has tested and would be amenable to an upgrade.

o   Mitochondrial DNA test people who descend through all females from various female ancestors in order to determine their origins. Y and mtDNA tests are an important part of a complete genealogy story – meaning the reasonably exhaustive search!

o   Autosomal DNA test family members from various lines with the hope that matches will match you and them both.

o   Test family members in order to confirm a particular ancestor – preferably people who descend from another child of that ancestor.

o   Making sure your own DNA is in all 4 of the major vendors’ data bases, plus GedMatch. Look at it this way, everyone who is at GedMatch or at a third party (non-testing) site had to have tested at one of the major 4 vendors – so if you are in all of the vendor’s data bases, plus GedMatch, you’re covered.

Have a wonderful New Year and let’s make 2018 the year of newly discovered ancestors and solved mysteries!

Concepts – DNA Recombination and Crossovers

What is a crossover anyway, and why do I, as a genetic genealogist, care?

A crossover on a chromosome is where the chromosome is cut and the DNA from two different ancestors is spliced together during meiosis as the DNA of the offspring is created when half of the DNA of the two parents combines.

Identifying crossover locations, and who the DNA that we received came from is the first step in identifying the ancestor further back in our tree that contributed that segment of DNA to us.

Crossovers are easier to see than conceptualize.

Viewing Crossovers

The crossover is the location on each chromosome where the orange and black DNA butt up against each other – like a splice or seam.

In this example, utilizing the Family Tree DNA chromosome browser, the DNA of a grandchild is compared to the DNA of a grandparent. The grandchild received exactly 50 percent of her father’s DNA, but only the average of 25% of the DNA of each of her 4 grandparents. Comparing this child’s DNA to one grandmother shows that she inherited about half of this grandmother’s DNA – the other half belonging to the spousal grandfather.

  • The orange segments above show the locations where the grandchild matches the grandmother.
  • The black sections (with the exception of the very tips of the chromosomes) show locations where the grandchild does not match the grandmother, so by definition, the grandchild must match the grandfather in those black locations (except chromosome tips).
  • The crossover location is the dividing line between the orange and black. Please note that the ends of chromosomes are notoriously difficult and inconsistent, so I tend to ignore what appear to be crossovers at the tips of chromosomes unless I can prove one way or the other. Of the 22 chromosomes, 16 have at least one black tip. In some cases, like chromosome 16, you can’t tell since the entire chromosome is black.
  • Ignore the grey areas – those regions are untested because they are SNP poor.

We know that the grandchild has her grandmother’s entire X chromosome, because the parent is a male who only inherited an X chromosome from his mother, so that’s all he had to give his daughter. The tips of the X chromosome are black, showing that the area is not matching the mother, so that region is unstable and not reported.

It’s also interesting to note that in 6 cases, other than the X chromosome, the entire chromosome is passed intact from grandparent to grandchild; chromosomes 4, 11, 16, 20, 21 and 22.

Twenty-six crossovers occurred between mother and son, at 5cM.  This was determined by comparing the DNA of mother to son in order to ascertain the actual beginning and end of the chromosome matching region, which tells me whether the black tips are or are not crossovers by comparing the grandchild’s DNA to the grandmother.

For more about this, you might want to read Concepts – Segment Survival – Three and Four Generation Phasing.

Before going on, let’s look at what a match between a parent and child looks like, and why.

Parent/Child Match

If you’re wondering why I showed a match between a grandchild and a grandparent, above, instead of showing a match between a child and a parent, the chromosome browser below provides the answer.

It’s a solid orange mass for each chromosome indicating that the child matches the parent at every location.

How can this be if the child only inherits half of the parent’s DNA?

Remember – the parent has two chromosomes that mix to give the child one chromosome.  When comparing the child to the parent, the child’s single chromosome inherited from the parent matches one of the parent’s two chromosomes at every address location – so it shows as a complete match to the parent even though the child is only matching one of the parent’s two of chromosome locations.  This isn’t a bug and it’s just how chromosome browsers work. In other words, the “other ” chromosome that your parents carry is the one you don’t match.

The diagram below shows the mother’s two copies of chromosome 1 she inherited from her father and mother and which section she gave to her child.

You can see that the mother’s father’s chromosome is blue in this illustration, and the mother’s mother’s chromosome is pink.  The crossover points in the child are between part B and C, and between part C and D.  You can clearly see that the child, when compared to the mother, does in fact match the mother in all locations, or parts, 3 blue and 1 pink, even though the source of the matching DNA is from two different parents.

This example shows the child compared to both parents, so you can see that the child does in fact match both parents on every single location.

This is exactly why two different matches may match us on the same location, but may not match each other because they are from different sides of our family – one from Mom’s side and one from Dad’s.

You can read more about this in the article, One Chromosome, Two Sides, No Zipper – ICW and the Matrix.

The only way to tell which “sides” or pieces of the parent’s DNA that the child inherited is to compare to other people who descend from the same line as one of the parents.  In essence, you can compare the child to the grandparents to identify the locations that the child received from each of the 4 grandparents – and by genetic subtraction, which segments were NOT inherited from each grandparent as well, if one grandparent happens to be missing.

In our Parental Chromosome pink and blue diagram illustration above, the child did NOT inherit the pink parts A, B and D, and did not inherit the blue part C – but did inherit something from the parent at every single location. They also didn’t inherit an equal amount of their grandparents pink and blue DNA. If they inherited the pink part, then they didn’t inherit the blue part, and vice versa for that particular location.

The parent to child chromosome browser view also shows us that the very tip ends of the chromosomes are not included in the matching reports – because we know that the child MUST match the parent on one of their two chromosomes, end to end. The download or chart view provides us with the exact locations.

This brings us to the question of whether crossovers occur equally between males and female children.  We already know that the X chromosome has a distinctive inheritance pattern – meaning that males only inherit an X from their mothers.  A father and son will NEVER match on the X chromosome.  You can read more about X chromosome inheritance patterns in the article, X Marks the Spot.

Crossovers Differ Between Males and Females

In the paper Genetic Analysis of Variation in Human Meiotic Recombination by Chowdhury, et al, we learn that males and females experience a different average number of crossovers.

The authors say the following:

The number of recombination events per meiosis varies extensively among individuals. This recombination phenotype differs between female and male, and also among individuals of each gender.

Notably, we found different sequence variants associated with female and male recombination phenotypes, suggesting that they are regulated by different genes.

Meiotic recombination is essential for the formation of human gametes and is a key process that generates genetic diversity. Given its importance, we would expect the number and location of exchanges to be tightly regulated. However, studies show significant gender and inter-individual variation in genome-wide recombination rates. The genetic basis for this variation is poorly understood.

The Chowdhury paper provides the following graphs. These graphs show the average number of recombinations, or crossovers, per meiosis for each of two different studies, the AGRE and the FHS study, discussed in the paper.

The bottom line of this paper, for genetic genealogists, is that males average about 27 crossovers per child and females average about 42, with the AGRE study families reporting 41.1 and the FHS study families reporting 42.8.

I have been collaborating with statistician, Philip Gammon, and he points out the following:

Male, 22 chromosomes plus the average of 27 crossovers = an average of 49 segments of his parent’s DNA that he will pass on to his children. Roughly half will be from each of his parents. Not exactly half. If there are an odd number of crossovers on a chromosome it will contain an even number of segments and half will be from each parent. But if there are an even number of crossovers (0, 2, 4, 6 etc.) there will be an odd number of segments on the chromosome, one more from one parent than the other.

The average size of segments will be approximately:

  • Males, 22 + 27 = 49 segments at an average size of 3400 / 49 = 69 cM
  • Females, 22 + 42 = 64 segments at an average size of 3400 / 64 = 53 cM

This means that cumulatively, over time, in a line of entirely females, versus a line of entirely males, you’re going to see bigger chunks of DNA preserved (and lost) in males versus females, because the DNA divides fewer times. Bigger chunks of DNA mean better matching more generations back in time. When males do have a match, it would be likely to be on a larger segment.

The article, First Cousin Match Simulations speaks to this as well.

Practically Speaking

What does this mean, practically speaking, to genetic genealogists?

Few lines actually descend from all males or all females. Most of our connections to distant ancestors are through mixtures of male and female ancestors, so this variation in crossover rates really doesn’t affect us much – at least not on the average.

It’s difficult to discern why we match some cousins and we don’t match others. In some cases, rather than random recombination being a factor, the actual crossover rate may be at play. However, since we only know who we do match, and not who tested and we don’t match, it’s difficult to even speculate as to how recombination affected or affects our matches. And truthfully, for the application of genetic genealogy, we really don’t care – we (generally) only care who we do match – unless we don’t match anyone (or a second cousin or closer) in a particular line, especially a relatively close line – and that’s a horse of an entirely different color.

To me, the burning question to be answered, which still has not been unraveled, is why a difference in recombination rates exists between males and females. What processes are in play here that we don’t understand? What else might this not-yet-understood phenomenon affect?

Until we figure those things out, I note whether or not my match occurred through primarily men or women, and simply add that information into the other data that I use to determine match quality and possible distance.  In other words, information that informs me as to how close and reasonable a match is likely to be includes the following information:

  • Total amount of shared DNA
  • Largest segment size
  • Number of matching segments
  • Number of SNPs in matching segment
  • Shared matches
  • X chromosome
  • mtDNA or Y DNA match
  • Trees – presence, absence, accuracy, depth and completeness
  • Primarily male or female individuals in path to common ancestor
  • Who else they match, particularly known close relatives
  • Does triangulation occur

It would be very interesting to see how the instances of matches to a certain specific cousin level – say 3rd cousins (for example), fare differently in terms of the average amount of shared DNA, the largest segment size and the number of segments in people descended from entirely female and entirely male lines. Blaine Bettinger, are you listening? This would be a wonderful study for the Shared cM Project which measures actual data.

Isn’t the science of genetics absolutely fascinating???!!!

Imputation Matching Comparison

In a future article, I’ll be writing about the process of uploading files to DNA.Land and the user experience, but in this article, I want to discuss only one topic, and that’s the results of imputation as it affects matching for genetic genealogy. DNA.Land is one of three companies known positively to be using imputation (DNA.Land, MyHeritage and LivingDNA), and one of two that allows transfers and does matching for genealogy

This is the second in a series of three articles about imputation.

Imputation, discussed in the article, Concepts – Imputation, is the process whereby your DNA that is tested is then “expanded” by inferring results you don’t have, meaning locations that haven’t been tested, by using information from results you do have. Vendors have no choice in this matter, as Illumina, the chip maker of the DNA chip widely utilized in the genetic genealogy marketspace has obsoleted the prior chip and moved to a new chip with only about 20% overlap in the locations previously tested. Imputation is the methodology utilized to attempt to bridge the gap between the two chips for genetic genealogy matching and ethnicity predications.

Imputation is built upon two premises:

1 – that DNA locations are inherited together

2 – that people from common populations share a significant amount of the same DNA

An example of imputation that DNA.Land provides is the following sentence.

I saw a blue ca_ on your head.

There are several letters that are more likely that others to be found in the blank and some words would be more likely to be found in this sentence than others.

A less intuitive sentence might be:

I saw a blue ca_ yesterday.

DNA.Land doesn’t perform DNA testing, but instead takes a file that you upload from a testing vendor that has around 700,000 locations and imputes another 38.3 million variants, or locations, based on what other people carry in neighboring locations. These numbers are found in the SNPedia instructions for uploading DNA.Land information to their system for usage with Promethease.

I originally wrote about Promethease here, and I’ll be publishing an updated article shortly.

In this article, I want to see how imputation affects matching between people for genetic genealogy purposes.

Genetic Genealogy Matching

In order to be able to do an apples to apples comparison, I uploaded my Family Tree DNA autosomal file to DNA.Land.

DNA.Land then processed my file, imputed additional values, then showed me my matches to other people who have also uploaded and had additional locations imputed.

DNA.Land has just over 60,000 uploads in their data base today. Of those, I match 11 at a high confidence level and one at a speculative level.

My best match, meaning my closest match, Karen, just happened to have used her GedMatch kit number for her middle name. Smart lady!

Karen’s GedMatch number provided me with the opportunity to compare our actual match information at DNA.Land, then also at GedMatch, then compare the two different match results in order to see how much of our matching was “real” from portions of our tested kits that actually match, and what portion of our DNA matches as a result of the DNA.Land imputation.

At DNA.Land, your match information is presented with the following information:

  • Relationship degree – meaning estimated relationship
  • # shared segments – although many of these are extremely small
  • Total shared cM
  • Total recent shared length in cM
  • Longest recent shared segment in cM
  • Relationship likelihood graph
  • Shared segments plotted on chromosome display
  • Shared segments in a table

Please note that you can click on any graphic to enlarge.

DNA.Land provides what they believe to be an accurate estimate of recent and anciently shared SNA segments.

The match table is a dropdown underneath the chromosome graphic at far right:

For this experiment, I copied the information from the match table and dropped it into a spreadsheet.

DNALand Match Locations

My match information is shown at DNA.Land with Karen as follows:

Matching segments are identified by DNA.Land as either recent or ancient, which I find to be over-simplified at best and misleading or inaccurate at worst. I guess it depends on how you perceive recent and ancient. I think they are trying to convey the concept that larger segments tend to me more recent, and smaller segments tend to be older, but ancient in the genetics field often refers to DNA extracted from exhumed burials from thousands of years ago.  Furthermore, smaller segments can be descended from the same ancestor as larger segments.

GedMatch Match

Since Karen so kindly provided her GedMatch kit number, I signed in to GedMatch and did a one-to-one match with this same kit.

Since all of the segments are 3 cM and over at DNA.Land, I utilized a GedMatch threshold of 3 cM and dropped the SNP count to 100, since a SNP count of 300 gave me few matches. For this comparison, I wanted to see all my matches to Karen, no matter how few SNPs are involved, in an attempt to obtain results similar to DNA.Land. I normally would not drop either of these thresholds this low. My typical minimum is 5cM and 500 SNPs, and even if I drop to 3cM, I still maintain the 500 SNP threshold.

Let’s see how the data from GedMatch and DNA.Land compares.

In my spreadsheet, below, I pasted the segment match information from DNA.Land in the first 5 columns with a red header. Note that DNA.Land does not provide the number of shared SNPs.

At right, I pasted the match information from GedMatch, with a green header. We know that GedMatch has a history of accurately comparing segments, and we can do a cross platform comparison. I originally uploaded my FTDNA file to DNA.Land and Karen uploaded an Ancestry file. Those are the two files I compared at GedMatch, because the same actual matching locations are being compared at both vendors, DNA.Land (in addition to imputed regions) and GedMatch.

I then copied the matching segments from GedMatch (3cM, 100 SNPs threshold) and placed them in the middle columns in the same row where they matched corresponding DNA.Land segments. If any portion of the two vendors segments overlapped, I copied them as a match, although two are small and partial and one is almost negligible. As you can see, there are only 10 segments with any overlap at all in the center section. Please note that I am NOT suggesting these are valid or real matches.  At this point, it’s only a math/match exercise, not an analysis.

The match comparison column (yellow header) is where I commented on the match itself. In some cases, the lack of the number of SNPs at DNA.Land was detrimental to understanding which vendor was a higher match. Therefore, when possible, I marked the higher vendor in the Match Comparison column with the color of their corresponding header.

Analysis

Frankly, I was shocked at the lack of matching between GedMatch and DNA.Land. Trying to understand the discrepancy, I decided to look at the matches between Karen, who has been very helpful, and me at other vendors.

I then looked at our matches at Ancestry, 23andMe, MyHeritage and at Family Tree DNA.

The best comparison would be at Family Tree DNA where Karen loaded her Ancestry file.  Therefore, I’m comparing apples to apples, meaning equivalent to the comparison at GedMatch and DNA.Land (before imputation).

It’s impossible to tell much without a chromosome browser at Ancestry, especially after Timber processing which reduces matching DNA.

DNA.Land categorized my match to Karen as “high certainty.” My match with Karen appears to be a valid match based on the longest segment(s) of approximately 30cM on chromosome 8.

  • Of the 4 segments that DNA.Land identifies as “recent” matches, 2 are not reflected at all in the GedMatch or Family Tree DNA matching, suggesting that these regions were imputed entirely, and incorrectly.
  • Of the 4 segments that DNA.Land identifies as “recent” matches, the 2 on chromosome 8 are actually one segment that imputation apparently divided. According to DNA.LAND, imputation can increase the number of matching segments. I don’t think it should break existing segments, meaning segments actually tested, into multiple pieces. In any event, the two vendors do agree on this match, even though DNA.Land breaks the matching segment into two pieces where GedMatch and Family Tree DNA do not. I’m presuming (I hate that word) that this is the one segment that Ancestry calls as a match as well, because it’s the longest, but Ancestry’s Timber algorithm downgrades the match portion of that segment by removing 11cM (according to DNA.Land) from 29cM to 18cM or removes 13cM (according to both GedMatch and Family Tree DNA) from 31cM to 18cM. Both GedMatch and Family Tree DNA agree and appear to be accurate at 31cM.
  • Of the total 39 matching segments of any size, utilizing the 3cM threshold and 100 SNPs, which I set artificially very low, GedMatch only found 10 matching segments with any portion of the segment in common, meaning that at least 29 were entirely erroneous matches.
  • Resetting the GedMatch match threshold to 3 cM and 300 SNPS, a more reasonable SNP threshold for 3cM, GedMatch only reports 3 matching segments, one of which is chromosome 8 (undivided) which means at this threshold, 36 of the 39 matching DNA.Land segments are entirely erroneous. Setting the threshold to a more reasonable 5cM or 7cM and 500 SNPs would result in only the one match on chromosome 8.

  • If 29 of 39 segments (at 3cM 100 SNPs) are erroneously reported, that equates to 74.36% erroneous matches due to imputation alone, with out considering identical by chance (IBC) matches.
  • If 35 of 39 segments (at 3cM 300 SNPs) are erroneously reported, that equates to 89.74% percent erroneous matches, again without considering those that might be IBC.

Predicted vs Actual

One additional piece of information that I gathered during this process is the predicted relationship.

Vendor Total cM Total Segments Longest Segment Predicted Relationship
DNA.Land 162 to 3 cM 39 to 3 cM 17.3 & 12, split 3C
GedMatch 123 to 3 cM 27 to 3 cM 31.5 5.1 gen distant
Family Tree DNA 40 to 1 cM 12 to 1 cM 32 3-5C
MyHeritage No match No match No match No match
Ancestry 18.1 1 18.1 5-8C
23andMe 26 1 26 3-6C

Karen utilized her Ancestry file and I used my Family Tree DNA file for all of the above matching except at 23andMe and Ancestry where we are both tested on the vendors’ platform. Neither 23andMe nor Ancestry accept uploads. I included the 23andMe and Ancestry comparisons as additional reference points.

The lack of a match at MyHeritage, another company that implements imputation, is quite interesting. Karen and I, even with a significantly sized segment are not shown as a match at MyHeritage.

If imputation actually breaks some matching segments apart, like the chromosome 8 segment at DNA.Land, it’s possible that the resulting smaller individual segments simply didn’t exceed the MyHeritage matching threshold. It would appear that the MyHeritage matching threshold is probably 9cM, given that my smallest segment match of all my matches at MyHeritage is 9cM. Therefore, a 31 or 32 cM segment would have to be broken into 4 roughly equally sized pieces (32/4=8) for the match to Karen not to be detected because all segment pieces are under 9cM. MyHeritage has experienced unreliable matching since their rollout in mid 2016, so their issue may or may not be imputation related.

The Common Ancestor

At Family Tree DNA, Karen does not match my mother, so I can tell positively that she is related through my father’s line. She and I triangulate on our common segment with three other individuals who descend from Abraham Estes 1647-1720 .

Utilizing the chromosome browser, we do indeed match on chromosome 8 on a long segment, which is also our only match over 5cM at Family Tree DNA.

Based on our trees as well as the trees of our three triangulated Estes matches, Karen and I are most probably either 8th cousins, or 8th cousins once removed, assuming that is our only common line. I am 8th cousins with the other three triangulated matches on chromosome 8. Karen’s line has yet to be proven.

Imputation Matching Summary

I like the way that DNA.Land presents some of their features, but as for matching accuracy, you can view the match quality in various ways:

  1. DNA.Land did find the large match on chromosome 8. Of course, in terms of matching, that’s pretty difficult to miss at roughly 30cM, although MyHeritage managed. Imputation did split the large match into two, somehow, even though Karen and I match on that same segment as one segment at other vendors comparing the same files.
  2. Of the 39 DNA.Land total matches, other than the chromosome 8 match, two other matches are partial matches, according to GedMatch. Both are under 7cM.
  3. Of DNA.Land’s total 39 matches, 35 are entirely wrong, in addition to the two that are split, including two inaccurate imputed matches at over 5cM.
  4. At DNA.Land, I’m not so concerned about discerning between “real” and “false” small segment matches, as compared to both FTDNA and GedMatch, as I am about incorrectly imputed segments and matches. Whether small matches in general are false positives or legitimate can be debated, each smaller segment match based on its own merits. Truthfully, with larger segments to deal with, I tend to ignore smaller segments anyway, at least initially. However, imputation adds another layer of uncertainty on top of actual matching, especially, it appears, with smaller matches. Imputing entire segments of incorrect DNA concerns me.
  5. Having said that, I find it very concerning that MyHeritage who also utilizes imputation missed a significant match of over 30cM. I don’t know of a match of this size that has ever been proven to be a false match (through parental phasing), and in this case, we know which ancestor this segment descends from through independent verification utilizing multiple other matches. MyHeritage should have found that match, regardless of imputation, because that match is from portions of the two files that were both tested, not imputed.

Summary

To date, I’m not impressed with imputation matching relative to genetic genealogy at either DNA.Land or MyHeritage.

In one case, that of DNA.Land, imputation shows matches for segments that are not shown as matches at either Family Tree DNA or GedMatch who are comparing the same two testers’ files, but without imputation. Since DNA.Land did find the larger segment, and many of their smaller segments are simply wrong, I would suggest that perhaps they should only show larger segments. Of course, anyone who finds DNA.Land is probably an experienced genetic genealogist and probably already has files at both GedMatch and Family Tree DNA, so hopefully savvy enough to realize there are issues with DNA.Land’s matching.

In the second imputation case, that of MyHeritage, the match with Karen is missed entirely, although that may not be a function of imputation. It’s hard to determine.  MyHeritage is also comparing the same two files uploaded by Karen and I to the other vendors who found that match, both vendors who do and don’t utilize imputation.

Regardless of imputing additional locations, MyHeritage should have found the matching segment on chromosome 8 because that region does NOT need to be imputed. Their failure to do so may be a function of their matching routine and not of imputation itself. At this point, it’s impossible to discern the cause. We only know, based on matching at other vendors, that the non-match at MyHeritage is inaccurate.

Here’s what DNA.Land has to say about the imputed VCF file, which holds all of your imputed values, when you download the file. They pull no punches about imputation.

“Noisey and probabilistic.” Yes, I’d say they are right, and problematic as well, at least for genetic genealogists.

Extrapolating this even further, I find it more than a little frightening that my imputed data at DNA.Land will be utilized for medical research.

Quoting now from Promethease, a medical reference site that allows the consumer to upload their raw data files, providing consumers with a list of SNPs having either positive or negative research in academic literature:

DNA.land will take a person’s data as produced by such companies and impute additional variants based on population frequency statistics. To put this in concrete terms, a person uploading a typical 23andMe file of ~700,000 variants to DNA.land will get back an (imputed) file of ~39 million variants, all predicted to be present in the person. Promethease reports from such imputed files typically contain about 50% more information (i.e. 50% more genotypes) than the corresponding reports from raw (non-imputed) data.

Translated, this means that your imputed data provides twice as much “genetic information” as your actual tested data. The question remains, of course, how much of this imputed data is accurate.

That will be the topic of the third imputation article. Stay tuned.

Family Tree DNA Sale, MyHeritage Transfers and Hurricane Fundraiser

As many of you know, the owners of Family Tree DNA, a Houston company, have committed a percentage of their sales during the month of September for donation to hurricane Harvey disaster relief efforts. A daily running total is displayed at the top of their page.

I think they will top $20,000 today!

I know that with two more hurricanes (Irma an Maria) and two earthquakes in Mexico, Harvey, which ravaged Texas less than 3 weeks ago seems like old news. It’s not to the families whose lives have been upended and who have lost everything, not only due to the winds of the hurricane along the coast, but unprecedented flooding in Houston for the following week. Those families are still cleaning mud out of their homes, ripping off their sheetrock, and so much more. Thousands are displaced and have lost everything.

The best part about the Family Tree DNA fundraiser is that you can contribute to the relief effort without any additional cost to you. In fact, there’s a lot of benefit to everyone – you benefit when you order a test or upgrade, other people whose genealogy may depend on your testing benefit, and the families trying to recover from Harvey benefit as well. You never know, maybe the person you desperately need to knock down a brick wall will test or transfer now!

Everyone wins! But you only have another week, so don’t wait.

Family Tree DNA just sweetened the deal in three ways too.

Deal Sweeteners

MyHeritage Transfer

Family Tree DNA has just added MyHeritage as a transfer partner, meaning if you tested at MyHeritage, you can transfer your results to Family Tree DNA and see matches for free.

The autosomal DNA transfer option for MyHeritage as well as other vendors can be found, here, in the upper left hand corner of the main Family Tree DNA page, under DNA Tests.

Family Tree DNA accepts transfers from:

  • Ancestry
  • 23andMe V3 and V4
  • MyHeritage

Family Finder Just $69

The Family Finder autosomal test is on sale now for $69, a $20 savings. If you haven’t tested yet, or have transferred the 23andMe V4 or Ancestry V2 tests which only provide your closest matches, and not the more distant ones (due to chip incompatibility), now is a great time to order a Family Finder test. I don’t know how long the sale price lasts, so if you’re interested, buy now.

Unlock All Transfer Features Just $10

In addition, Family Tree DNA has dropped the price of unlocking the full suite of autosomal tools available after the free transfer of your results. You receive your matches for free, but by adding the $10 unlock, on sale reduced from the regular $19 until the end of September, you add three features:

  • Chromosome Browser
  • myOrigins (ethnicity)
  • ancientOrigins.

You will need a coupon code, so you can use mine. These codes are NOT limited to one use only, so please feel free to upgrade as many tests as you wish.

USE CODE: ATUL0917

Here’s what the unlock gives you access to, in addition to your free matches.

Transferring and Unlocking is Easy…

  • Click here to upgrade, unlock (ATUL0917) or transfer your results from another vendor.
  • Then sign on to your own account to transfer, unlock or upgrade if you already have an account at Family Tree DNA.

Glossary – DNA – Deoxyribonucleic Acid

What is DNA and why do I care?

Good questions. Let’s take a look at the answer in general, then why we use DNA for genealogy.

The Recipe for You

DNA, deoxyribonucleic acid, is the book of life for all organisms. In essence, it’s the recipe for you – and what makes you unique.

DNA is formed of strands that twist to form the familiar double helix pattern.

The two strands are joined together by one of 4 different nucleotides, one extending from each side to connect in the middle. The nucleotides are:

  • Cytosine – C
  • Guanine – G
  • Thymine – T
  • Adenine – A

The nucleotide names don’t really matter for genetic genealogy, but what does matter is that the sequence of these nucleotides when chained together is what encodes information on long structures called chromosomes. Each person carries 22 chromosomes, plus the 23rd chromosome pair which is gender specific.

Using DNA for Genetic Genealogy

There are four different kinds of DNA that genealogists use in different ways for obtaining ancestors’ information relevant to genetic genealogy. Thankfully, we have 4 different kinds of DNA available to us because of unique inheritance patterns for each kind of DNA – meaning we inherited different kinds of DNA from different ancestral paths. If one kind of DNA doesn’t work in a particular situation, chances are good that another type will.

Genetic genealogy makes use of 4 different types of DNA.

  • Y DNA – passed from males to male children, only (your father’s paternal line)
  • Mitochondrial DNA – passed from females to both genders of children, but only females pass it on (your mother’s matrilineal line)

Y and mitochondrial DNA inheritance paths are shown on a pedigree chart in the graphic below, with the blue boxes representing Y DNA and the red circles representing mitochondrial DNA inheritance.

In addition to Y and mitochondrial DNA, genetic genealogists also use two kinds of DNA that reflect inheritance from additional ancestral lines, in addition to the red and blue lines shown above – meaning the ancestral lines with no color.

  • Autosomal DNA – the 22 chromosomes that recombine during reproduction.
  • X Chromosome – always contributed by the mother, but only contributed by the father to female children – this is the 23rd chromosome pair which recombines with a unique inheritance pattern.  You can read more about that in the article, X Marks the Spot.

Receiving What Kind of DNA from Whom

While the Y and mitochondrial DNA have unique and very prescribed inheritance patterns as shown by the red arrows pointing to the blue Y chromosome below at far left, and the red mitochondrial circles at far right, the 22 autosomal chromosomes are contributed equally by each parent. In other words, for each chromosome, a child inherits half of each parent’s DNA. How the selection of which DNA is contributed to each child is unknown.

A child’s gender is determined by the parent’s contributions to the 23rd chromosome, not shown above. The following chart explains gender determination by the X and Y combinations of the 23rd chromosome.

Received from Mother Received from Father
Male child X Y
Female child X X

The Y chromosome is what makes males male.

No Y chromosome?  You’re a female.

However, this X chromosome inheritance pattern provides us with the ability to look at X matches for males and know immediately that they had to have come from his mother’s lineage – because males don’t inherit an X chromosome from their father.

Autosomal DNA and Genetic Genealogy

The 22 non-gender chromosomes recombine in each generation, with half of each chromosome being contributed by each parent, as shown in the illustrations above.

You can see that in the first generation, the child received one blue and one yellow, or one pink and one green, chromosome. In giving each child exactly half of their DNA, each parent contributes some amount of ancestral DNA from generations upstream, as you can see in the mother/father and son/daughter generations.

For example, each child receives, on average, 25% of each of their grandparent’s DNA – although they can receive somewhat more or less than 25%, depending on the random nature of recombination.

Therefore, genetic genealogy testing companies compare tester’s autosomal DNA with other testers and look for common segments contributed by common ancestors, resulting in autosomal matching.

When relatively large segments match between three or more relatives who are not immediate family, we can attribute that DNA to a common ancestor. Of course, the challenge, and the thrill, is to determine which common ancestor contributed that common DNA to our triangulated match group. It’s a great way to verify our research and to break down brick walls.

Let’s face it, you received ALL of your DNA from SOME combination of ancestors, and if you carry large enough pieces from any specific ancestor, we can, hopefully, identify the source of that DNA segment by looking at the genealogy of those we match on that segment.

It’s a great puzzle to unravel, and best of all, it’s the puzzle of you.

More Info

The great news is that you can utilize your Y DNA, mitochondrial DNA and autosomal DNA differently, to provide you with different kinds of information about different ancestors and genealogy lines.
