Why DNA Matches Appear Closer Than They Are

DNA match Maria and I are 6th cousins twice removed. I've done the research work, as has she. My 7th great grandparents Domenico and Filippa are her 5th great grandparents. Our relationship is through my paternal grandfather's branch. According to Blaine Bettinger's Shared cM Project, she and I should share 0–45 cMs because we're so distant. But we don't. We share 79 cMs (centiMorgans). That's enough for us to be solid 3rd cousins.

A chart on the ISOGG Wiki says there's an 11% chance that 6th cousins testing with AncestryDNA^® will share any DNA. And this is my 6th cousin twice removed!

Exclude Smaller Amounts of DNA

So why do some DNA matches appear to be much closer cousins than they are? The answer in this case is endogamy. Endogamy is a long history of marrying within a closed community. And it ran rampant among my ancestors. My roots run deep in a handful of neighboring hills towns in the Campania region of Italy. Populations stayed put for centuries. Everyone married someone from town or someone from the next town.

Keep in mind your 3rd–4th cousin DNA matches may be more distant than they appear.

All that swimming in the same gene pool makes for some complex relationships. But what if DNA match Maria and I have another, more distant relationship? If we do, then our shared 79 cMs may be the sum total of smaller, unrelated amounts. We may be getting up to 45 cMs from Domenico and Filippa and 34 more cMs from other shared ancestors.

If your DNA testing service has a chromosome browser (FamilyTreeDNA or 23andMe^®), use it to focus on the longer stretches of DNA you share with a match. If you exclude the very short spans, you're left with a more realistic amount of meaningful shared DNA. That smaller number may point to your true relationship.

Find Another DNA Source

For reasons I can't understand, AncestryDNA doesn't offer a chromosome browser. That means I can't focus on only the long stretches of DNA Maria and I share. Luckily, I've found our main relationship. To account for the extra DNA, I need to expand the common branches of our family trees. I need to look for other relationships.

I found a possibility, but it requires one logical assumption. Maria's great grandfather Giuseppe Basilone was born in about 1852. There are only two Giuseppe Basilones born in the town at that time. (Find out how I know there are only two.) There are no available marriage or death records to prove my theory. But there is logic.

I took the bold step of merging two people in my family tree:

• 1852 Giuseppe Basilone of unknown ancestry, and
• 1851 Giuseppe Onofrio Basilone, who happens to be my 2nd cousin 4 times removed.

When documents are not available, thorough research around your person can help.

Why was I comfortable doing this? Because:

• Giuseppe Onofrio was 32 years older than his wife when he married in 1904. (I have the 1904 date from his wife's birth record.)
• The Giuseppe I'm trying to connect to had 4 children from 1878–1886, and then they stopped coming.
• It's logical that Giuseppe's first wife died after 1886, and he remarried a much younger woman.
• The only other possible match is a Giuseppantonio (not Giuseppe) Basilone. He's a dead end. There's no annotation about his marriage, and there are no birth records for his children.

Still, this is a theory, so I wrote a detailed note about it in my family tree. If I'm correct, DNA match Maria is now also my 5th cousin once removed. This relationship is through my paternal grandmother. My 5th great grandparents Paolo and Giuseppa are her 4th great grandparents. We just got closer! That relationship is good for about 21 cMs, or a range of 0–80 cMs. This extra relationship would explain why Maria and I share 79 cMs but are distant cousins.

Two distant relationships added together can seem like a much closer cousin.

Don't Get Hung Up on Estimates

What does this mean to you when you're checking out your DNA matches? Once you get past 2nd or 3rd cousins, every other match may be more distant than they appear. This is especially true if you come from an endogamous population like me. Other well-known endogamous populations are:

• Acadians
• Amish
• Arabs
• Ashkenazi Jews
• French Canadians
• Mennonites
• Newfoundlanders
• Polynesians

Think of the early settlers of Colonial America. Their community was pretty small, so how many marital choices did one have? This was the case with all my semi-isolated Italian towns.

Don't fret about the estimated cousin relationship if the facts don't support it. Instead, look for other, hidden relationships.

Keep Genealogy Exciting With This One List

I abandoned my annual genealogy goals in the year of the plague—2020. It seemed pointless to be so disciplined when it felt like the end of the world.

Did I give up on my family tree research? Just the opposite. I've become more productive at building my family tree. Even before I retired from my job three months ago, I was spending time on genealogy every single day. Now that I am retired, my family tree is my full-time job.

Do you ever worry about becoming bored with your genealogy research? I don't. The research routine I've settled into keeps me engaged and entertained. Every day!

The secret is to (a) have a list of tasks you can work on, and (b) do whatever you're in the mood to do. On any given day, I may pick a task and go at it, or jump from task to task, or let my findings lead me where they want to go.

Create a list of genealogy research tasks for yourself, and you can always do what makes you happy on any given day. Let me explain my list, and you can think about what to put on yours.

Steady progress on your family tree is always entertaining when you have tasks to suit your mood.

My list revolves around my ultimate goal for my family tree. This is not for everyone, but I know I've inspired some of you. My goal is to connect everyone from my ancestral hometowns in one massive family tree.

While researching a town in Italy, I found connections between everyone in town. All my ancestral hometowns are rural and isolated. Everyone married someone else in town or from a neighboring town. And all my hometowns are neighboring towns.

My towns' vital records are available online. After finding as many of my direct ancestors as possible, I wanted to fill out each individual family. Who did my direct ancestors' siblings marry? Who were their children? I can answer those questions, limited only by the years for which vital records are available.

In trying to connect everyone from my towns, I have an enormous family tree with well over 34,000 people. Lately, by doing whatever makes me happy, I've been adding an average of 100 people a day to my tree.

Here are my favorite genealogy tasks. Each day I start working on whichever one will make me happy at that moment.

Task 1. Research people with approximate birth dates.

There are lots of people in my tree without an exact birth date. For many of them, all I need to do is search for the right document.

My favorite task right now is finding a date of birth for everyone possible.

First I sort everyone in my Family Tree Maker file by birth date. I began this task with people born in the 1780s. Italian civil records begin in 1809, but the early marriage records can include a birth date.

I'm up to people born in 1827. When I find someone's birth record, I add their parents. Then I search for all their siblings and see who each one married. I find each couple's children and the families of each spouse. The people add up fast, which is why I'm averaging 100 people a day.

Task 2. Fill in missing facts in my document tracker.

When I add a genealogy document to my family tree, I record it in a single spreadsheet I call my document tracker. I sort the 5,000+ lines by last name with one line per person.

One year my genealogy goal was to search for missing U.S. census records for the people in my document tracker. Now I'm going line-by-line finding missing vital records for every Italian.

If I find a birth, marriage, and death record for someone, I color the line green so I know I've found everything. If any dates are outside the range of available vital records, I note that and color the line blue. That tells me I've done all I can.

Task 3. Fit everyone from my Colle Sannita spreadsheet into my tree.

One of my 2019 goals was to transcribe the 1809–1813 birth records from my Italian towns in a spreadsheet. Now I'm focusing on my Grandpa Iamarino's hometown of Colle Sannita. I'm working to fit every single baby from these years into my tree.

The spreadsheet tells me the baby's name and birth date, and the parents' names and ages. Sometimes I find that the parents are already in my tree, so all I have to do is add the baby.

Other times I need to find out who the baby grew up to marry, and then see if I have that family in my tree. One way or another, I can fit almost everyone in. I'm currently down to line 145 in the spreadsheet, and there are only seven babies I can't place in my family tree. Yet.

Task 4. Download and label more Italian vital records.

My 2nd great grandmother was born in Santa Paolina. I find that many people from that town married someone from the next town, Tufo. Now I'm downloading Tufo record images from the Antenati website. Finding the Tufo birth, marriage, or death records I need to complete a family is so satisfying.

Each time I download a vital record, I rename it so the people are searchable on my computer. For example, one two-page record image from 1821 is on my computer as:

18 Michele Pasquale Romano di Giovanni & 19 Giovanni Raffaele Grosso di Domenico.jpg

The "di" tells me the name of the baby's father. This makes it easy for me to quickly find every child born to one couple. I can search my computer for "romano di giovanni" and check each result to see the mother's name.

I'm including the record numbers so a collection of files is in chronological order. I may need #18 Michele now, but later on, I'll probably need #19 Giovanni. When I do, I'll find his record easily.

I love viewing all the vital records and renaming them. It helps me get familiar with the last names from any given town. I can usually spot an out-of-towner by their unfamiliar last name.

Find a genealogy task you really enjoy. Then work on it whenever the mood strikes you.

Task 5. Reduce the size of huge document images.

Last year I learned a better way to save files in Photoshop to reduce their file size. (I'll explain this if anyone is interested.) My family tree has tons of bloated census pages, immigration records, and more. When the mood strikes me, I search for the fattest files and resave them. Then I replace the image in my tree. This helps reduce the overall size of my massive family tree file.

Task 6. Follow up on leads in my research notebook.

I have a text file I work in every single day called notebook.txt. It has my to-do list, information I need to keep handy, and it tells me where I left off on all the tasks above.

The file also contains leads and project ideas I've added over the years. One project revolves around photos I took in Italy. They are photos of monuments to the young men from three towns who died in World War I and II. My project is to fit each one of the men into my family tree.

My text file also has notes about some of my DNA matches, where I left off with genealogy hunches, and more. It even has a daily schedule of what I want my retirement to look like. I love to be productive, and my family tree is more than enough to keep me active and happy for the rest of my life.

What are you doing to keep up your genealogy research momentum?

Create an Ancestor Profile from Vital Records

How much can you ever know about your peasant ancestors? I spend all my time reading 19th-century vital records from a handful of rural Italian towns. Most records contain X's instead of signatures because almost everyone was illiterate.

In places like these, you can't expect to find your ancestors in the local society pages. No one could read, so there wouldn't be a need for such newspaper coverage. All you have are birth, marriage, and death records. Well, almost.

You can find some general local history about your ancestral towns. Last week I wrote about using Google Books to learn more about the places where your ancestors lived. You may find a good reference book in a library, too.

Without published stories, what can you learn about your family from vital records and a book or two? Here are examples from my extended family tree.

Successful Man Suffers Many Losses

When you find every available vital record for a family in your tree, you'll begin to see a snapshot of their lives.

Nicolangelo Nista was born in 1788 in my ancestral hometown of Colle Sannita, Italy. Piecing together the vital records for his immediate family, I discovered:

• His first wife and two of their daughters died on August 2, August 7, and August 9, 1834. The dates make it reasonable to think a sickness was going through the town at the time. That year saw many more deaths than the surrounding years.
• Four of his other children had already died before 1834.
• His wife's death left Nicolangelo with six children to raise, ranging in age from 18 to two years old.
• He married a younger widow the following year.
• They had four children together, two of whom died in infancy.
• His sister Nicolina was luckier in life, despite dying at the age of 46. She had at least two children who grew up, married, raised a family, and outlived her.
• His brother Giovanni became a priest and lived to be 78 years old.
• Nicolangelo lived to be more than 72 years old. The available death records for the town end in 1860, and Nicolangelo was still alive.
• He was a proprietario—an owner of property or a business. Despite his losses, Nicolangelo is likely to have lived a comfortable life.

Earthquake Hits Home

The same town of Colle Sannita has suffered several earthquakes. The 1962 earthquake damaged my grandfather's childhood home so badly, they had to demolish it. On my second visit to Grandpa's town, my cousins showed me the stone front doorstep. It was all that remained of his home.

I have a list of the 40 victims of an earthquake in Colle Sannita way back on 26 July 1805. Civil records for the town begin in 1809, yet I've managed to place a few of the victims in my family tree. One of them was my 38-year-old 5th great grandaunt, Libera Nigro.

See how one piece of local history from your ancestral hometown can add very real context to your family tree.

Libera and her husband Giovanni had three daughters that I've found. Sadly, Libera and two of her daughters, ages four and five, died in the 1805 earthquake. Without that list of victims, I would have no record of little Grazia and Anna Maria, my 1st cousins 6 times removed.

Suffering and Serendipity

I love to put entire families together from my ancestral hometowns. In doing so, I often see cases of several children dying young in the same family. It's so sad to see a couple name their baby Giuseppe, for example, only to have him die so soon. They name the next son Giuseppe, and he dies young. Then they name the next one Giuseppe. Each time I see this happen, I say, "That's a doomed name for them."

It also makes me sad to see a husband and wife die on the same day or a few days apart. These death records don't include a cause of death, but we may assume they died of the same cause. Maybe they both caught the flu or had some sort of accident.

One thing I noticed years ago always makes me laugh. You see, most of the old-country Italians in my family tree were poor. They usually gave their children one or two first names. For example, my 5th great grandparents named one son Angelo, and the other Tommaso Antonio.

Sometimes I find a well-to-do family. What's funny is that these richer families often give their children four or five first names. One such family named their children:

• Angela Maria Lorenza
• Maria Luisa Barbara Margarita
• Maria Amalia Carmela Camilla
• Domenico Maria (he got short-changed)
• Francesco Saverio Gaetano Achille
• Carolina Maria Vincenza

Pay attention to each detail from vital records. You may find common patterns like this.

Their father had the honorary titles of Don and Baron. At different times his occupation was landowner (proprietario), gentleman (galantuomo), or well-to-do (benestante). I always joke that these families were rich enough to afford more names for their babies.

The keys to developing a profile from vital records are:

• Find every available vital record for the immediate family.
• Notice the timing of events.
• Search for historical points of interest, like earthquakes, famine, disease, and war.

Surprising Free Finds from Google Books

Long-time reader of this blog, Suzanne, found two books that mention my great uncle. She had no luck on Newspapers.com, but she found him when she searched Google Books.

She encouraged me to pick up and continue the search. Two legal briefs help explain how my immigrant uncle and my great grandfather came to own a building. They were leasing it in 1905 from a brewing company—a company that may have had some bad lawyers. My ancestors parlayed this lease into ownership of the building where my mom was born.

What else might I find on Google Books? As usual, I didn't have much luck in searching for the names of my ancestors. Changing tactics, I searched for the names of my ancestral Italian hometowns. I searched for Santa Paolina, a small town in southern Italy, and I made a surprising discovery.

Imagine finding this one-of-a-kind biography of your ancestor.

In my family tree is the 1873 birth record for my 2nd cousin 4 times removed, Fioravanti Ricciardelli. His great grandfather, Emanuele Ricciardelli, is my 5th great grandfather. One search result in Google Books is "History of the Municipalities of Hudson County, New Jersey," written by Daniel Van Winkle in 1924. This isn't what I expected when searching for my town.

The book details the lives of Hudson County's notable citizens, including my cousin Fioravanti. Thanks to the page-and-a-quarter devoted to my cousin, I learned:

• His father, also named Emanuele Ricciardelli, was a "Red Shirt" who fought under Giuseppe Garibaldi for Italy's freedom.
• I knew from vital records that Emanuele and his wife had only 4 children in Santa Paolina. Now I know why. The book says the family moved to another town that's a half hour away by modern transportation. That's unexpected. They may have had more children in their new town.
• My cousin Fioravanti was an accomplished musician, business owner, and inventor.
• In America, he married a distant cousin from Santa Paolina, also named Ricciardelli. They had 9 children in New Jersey.
• The book says Fioravanti raised and educated all his siblings.

This is the type of detail I never get to learn about my Italian relatives. Even if I had discovered the family in U.S. documents, they wouldn't give me this much detail. Without this book, this family was a dead end. What a wonderful find!

Start Your Google Books Search

To search Google Books, go to google.com and start a search as usual. Then click "Books" below the search box. Note: You may have to click the word "More" before you see the "Books" option. Next, for more satisfying results, click the words "Any view" and choose "Preview and full view." Now you can fully explore the best results. If you find something you want, you may be able to download the book as a PDF. Note: You can save a step by going straight to https://books.google.com.

With this Google Books search, I can learn more about the WWI battle that almost killed my grandfather. What can you find?

Get creative with your searches. You never know what you'll find. Think about:

• People and Places. Try family and town names from your family tree. I found an 1888 Italian book about the history of my ancestral hometowns. It tells me their populations at the time.
• Historical Events. Which wars or other important events had an impact on your family? I'll search for the World War I battle where they captured my grandfather and imprisoned him for a year.
• Maps. I'd love to find a book with old maps of my towns of interest. The closest I came is a book with a folded-up map in the back. They didn't scan the unfolded map!
• Workplaces. Search for the company where your ancestor worked. What was happening when your relative worked there?

Devote one hour to Google Books and you'll understand more about your ancestors' lives. It's a massive resource. Thank you to Suzanne for reminding me to give it more attention.

An End-of-Year Tune Up for Your Family Tree

The end of the year is a perfect time to give your family tree a thorough check for errors. How many times during the past year did you:

• Add a person without checking if their birth date fits in with their parents and siblings?
• Change the way you record a particular fact, like someone's nickname?
• Accidentally attach a marriage date to the first spouse instead of the second?
• Update a person's birth year without changing their parents' estimated birth years?
• Attach a census fact to the youngest child in the family who wasn't born yet?

All kinds of human errors can happen while you're caught up in the genealogy zone. I generated two reports to find errors in my more than 33,000-person family tree:

• In Family Tree Maker, I ran the Data Errors Report.
• In Family Tree Analyzer, I opened a brand new GEDCOM file to look for the usual types of errors. If you don't use Family Tree Maker, create or download a GEDCOM file of your family tree. Then open it in Family Tree Analyzer and check out the error list.

Human error will always creep into your genealogy research. Here are 2 reports that will find the mistakes in your family tree.

I saved the Family Tree Maker report as a very long PDF file. It's long because it lists "The marriage date is missing" each time I don't know a couple's marriage date. That isn't an error. These early documents aren't available, so I'm ignoring that message.

The report also thinks it's an error when a husband and wife have the same last name. It isn't. I use only maiden names for the women in my family tree, but sometimes a Marino marries a Marino. What're you gonna do?

Here are the errors from the Family Tree Maker Data Errors Report that I'm fixing in my family tree:

• The birth date occurred before his/her father/mother was 13. This happens when new information changes my estimated birth date for a person. Let's say I add a person to my family tree with a birth year of 1800. If I know their parents' names, I give them an estimated birth year. My rule is to say the parents are 25 years older than their oldest child—until I find hard facts. So I'll give the 1800 baby's parents an estimated birth year of "Abt. 1775." But what if I discover that baby was born in 1782? If I don't redo the math for the parents' estimated birth year, I'll have a "parent too young" error.
• The birth date occurred after his/her mother was 60. I have two very large families where the children's births spanned way too many years. In one case, the oldest child was so much older than the rest that their birth year had to be wrong. I had to look at their children, too, to make sure I used a valid date estimate.
• The birth date occurred more than one year after his/her father died. This happened with people born in the 1700s. All I could do was adjust the child's birth year to the year their father died.
• The birth date occurred more than one year after his/her mother died. Same problem as above.
• Baptism date occurred before individual's birth date. This was my typo, and I' glad the report pointed it out.
• The individual was married before the age of 13. Unfortunately I have a couple of cases where that's true.
• The marriage occurred after the death date. A man's wife died before him, and I marked his death date as After her date. Then he remarried, and I forgot to delete that death estimate.

These reports will find conflicting facts in your family tree.

• The marriage occurred after the spouse's death. I must have given a marriage date to the first spouse instead of the second. It's too easy to make that mistake.
• Event immigration (or divorce or marriage) contains no data. I can't explain how some of these happened, so I appreciate this safety net.
• This individual's children sort order may be incorrect. I thought that was automatic. I may have clicked the wrong button on this family.
• Person does not have a preferred spouse set. Somehow I added marriage date without adding a spouse's name.
• The birth date is missing. These are living people I added recently. I don't know how old they are, so I'll have to add estimates based on their parents' ages.
• The name may include a nickname. I had a man's nickname in parentheses with his name. Now I've changed the nickname to an alternate Name fact.
• Residence date occurred before individual's birth date. The 1940 census says where the family lived in 1935. It may be the same house or the same place/town. Twice I gave the 1935 address to kids born after 1935. Now I've deleted those residence facts.
• The age at death is greater than 120. This is usually not an error. If I don't have a document to tell me when someone died, but I know they were dead when their child died, I'll say they died "Bef. [the child's death date]." This error report isn't taking the "Before" into account.
• The burial date occurred before his/her death. This was my typo, but yikes! What a thought.

Find those troublesome families in your family tree with one of these genealogy error reports.

When you're working in Family Tree Maker, the software will make an alert sound if:

• You add a baby to a parent who's too young, too old, or too dead.
• A bride or groom is under the age of 13.
• A husband and wife have the same last name.

I appreciate those warnings—except for the last one. But if you update someone's birth date later, you may not get the warning. That's what these reports are good for.

Give your family tree an error cleanse before the new year. Start off 2022 with a cleaned-up, fine-tuned, fortified family tree.
