How the Scientific Method Can Help You With Your Family Tree

Biology. Anthropology. Archaeology. They're all sciences, and lots of sciences end in -ology: "the study of". Genealogy is the study of lines of decent or development. Another science.

So it makes sense to use the well known Scientific Method in genealogy.

But how would that work? Well, the Scientific Method—principles and procedures for the systematic pursuit of knowledge—includes these steps:

1. Ask a Question. When were my great great grandparents married?

2. Construct a Hypothesis. Get very specific by looking at the genealogy facts you have. Do you know what year your great grandmother was born? Do you know when her parents were born? Were they old enough to have an earlier baby?

3. Test Your Hypothesis. When it comes to family trees, your research is your experiment. You can search available records for the answer to your question. I know my great grandmother was born in 1856. I know her parents' names and ages. My test is to search for other babies in 1855, 1854, 1853, etc., until the couple was too young to have children.

4. Analyze Your Data and Draw a Conclusion. Let's say you found more babies and then they stopped. You may conclude that your great great grandparents married at least nine months before the birth of their first child.

Let's see the Scientific Method in action on my family tree.

My first clues led to my question and hypothesis.

Ten years ago a friend in Italy went to the town hall in my ancestral hometown on my behalf. He requested a few birth, marriage and death records for me.

The town hall typed some of the important facts onto new forms. My friend sent copies of these forms to me.

I learned that my great grandmother, Marianna Iammucci, was born on January 1, 1856. Her parents names were not included.

A few years later I spent an extraordinary amount of time in a Family History Center poring over microfilmed vital records from this town. I went to the 1856 birth records and found Marianna Iammucci. I learned her parents were Antonio Iammucci born in 1814 and Annamaria Bozza born in 1815.

My question was, "How many brothers and sisters might she have had, and when was the first one born?"

Her parents were ages 41 and 40 in 1856. I hypothesized that there could be several more children born before my great grandmother. Since women in Italy at that time went well into their 40s bearing children, there might be some brothers or sisters after her, too.

Time to test my hypothesis. I checked the indexes of each year before 1856. While looking for babies born to Antonio Iammucci and Annamaria Bozza, I found:

• Luigi Maria born in November 1852
• Giovannangelo born in July 1849
• Leonardo Antonio born in December 1846
• Leonardo Antonio born in August 1845 (who died in February 1846)
• Mariangela born in March 1843

The babies seemed to stop there.

Analyzing these births, I concluded that Leonardo and Annamaria could have gotten married as late as June 1842.

Now we've come full circle! My conclusion about their June 1842 marriage became my next hypothesis. I went straight to the 1842 marriage index.

I found them. They were married on June 12, 1842. Success!

I've spent many a weekend jumping from person to person in my tree. It's unstructured fun. But it's the Scientific Method that gets me focused and produces excellent results.

Start thinking of your genealogy research as the science that it is. My hypothesis is you'll be very pleased you did. (And my conclusion is that sentence was horribly corny.)

Finding Your Ancestor's Lost Babies

When I began documenting my grandfather's Italian hometown—every single birth, marriage and death record between 1809 and 1860—one thing saddened me time and time again.

So many of the babies died within days, months, or a couple of years. I mourned for each one of them. It seemed even sadder that the next baby born was given the same name as the one who died.

Trying to be an optimistic genealogist, I focused on the upside. I was finding previously unknown children. Here's an example. I found that my great great grandparents Antonio and Colomba tried three times to name a child after Antonio's father: Raffaele.

My great uncle Raffaele was the third sibling named after his grandfather.

The first Raffaele died as a child, so none of my cousins were aware of him. Last night I found another baby! This time it was a girl they named Raffaella. She died, too, leaving that name to the great uncle we know: Raffaele Saviano.

When you're researching a family in the 1800s, expect to find a child born almost every year beginning a year after a marriage.

If an ancestor's family has several years between births, keep looking. There's a strong chance that other babies were born who didn't grow up.

My great great grandfather Nicoladomenico Leone married twice and fathered 12 children. About half of them survived to adulthood. See When I'm Sixty-Four I'll Still Have Only Two Children.

I don't know about you, but I want to know about and appreciate all the lost babies.

How I Gained 2 More Generations in 1 Day

Maria Rosa Caruso,
my great grandmother

Three months ago I wrote about how I used the "U.S. Social Security Applications and Claims Index" to learn the maiden name of my great grandmother's mother: Girardi.

Two months ago I wrote about how I'm downloading every vital record for my ancestral towns from an Italian genealogical archives web site.

Last night all that information came together to take me back two more generations on a branch of my family tree that hadn't grown in years.

Here's what happened.

I discovered many years ago that my great grandmother, Maria Rosa Caruso, was born in Pescolamazza, Italy. That was a problem at the outset because there is no such town! With a little research, I learned that Pescolamazza was renamed long ago to Pesco Sannita.

Pesco Sannita, in the province of Benevento, is a beautiful, well-manicured hill town that's very close to each of my other ancestral towns. (My heritage is highly concentrated!) I visited the town and its cemetery in 2005.

Over the last two days I downloaded every birth, marriage and death record for Pescolamazza from 1809 to 1942 (with a very big gap from 1861 to 1930). Once I had everything downloaded into sub-folders by year and type of document, I began searching for Maria Rosa Caruso's birth record and learned she had a twin brother Luca.

Maria Rosa's birth record.

This record confirmed her mother's full name of Maria Luigia Girardi. So I searched for Maria Luigia's 1840 birth record and found it. Et voila! I had her parents' names: Gioacchino Girardi and Maria Teresa deNigris.

I also found her husband's 1842 birth record—that's my great great grandfather Francesco Saverio Caruso—and learned his parents' names: Giuseppe Caruso and Luigia Pennucci.

The 1814 birth records are not available for Gioacchino Girardi and Maria Teresa deNigris, so I went searching for their marriage documents. Bingo!

The set of 1840 marriage documents told me that Gioacchino's middle name was Napoleone (was that 1814 patriotism or fear I wonder) and his parents were Nicola Girardi and Maria Pennucci. Maria Teresa's parents were Pasquale deNigris and Maria Emanuele Inglese.

Key facts from an Italian marriage record.

This generation of my 4x great grandparents was born between 1784 and 1793. I happily gained three new surnames (or cognomi in italiano): deNigris, Pennucci and Inglese.

I've expanded the families a bit more by finding two siblings for Maria Luigia Girardi and two for Francesco Saverio Caruso.

I will eventually squeeze every last drop of family out of these vital records as I did for my maternal grandfather's Italian hometown a few years ago.

Making Sense of Your DNA Results

I bought my DNA test from ancestry.com about five years ago, fairly soon after they made it available, and my pie chart was a bit of a shock. I've traced my ancestors back to the late 1600s, and they always lived in southern Italy. So the 44% Middle Eastern just seemed crazy.

My original pie chart and ethnicity
estimate from ancestry.com.

As time went on and more and more people submitted their DNA, the database became more robust and greater refinements were made. So now my chart is 75% Italian/Greek, and just a bit of other things. The 44% Middle Eastern is now 7%. That's a dramatic difference. So, if you get a DNA test, keep checking back for more information.

My current pie chart from ancestry.com.

But if my ancestors were in southern Italy in the 1600s, how do I have any Middle Eastern or European Jewish DNA? Your DNA can have its origins from a thousand or more years ago, and if you think about it, the southern Italians, Europeans, and many other populations did not originate in those places thousands of years ago.

They had to come from somewhere. And what did we learn in grade school social studies? That Mesopotamia was the cradle of civilization. That everything began where the Tigris meets the Euphrates. That's modern day Iraq.

If you look at my ethnicity map and see that Italian peninsula, it doesn't seem the least bit far-fetched to think that at some point people migrated from the Middle East to the Mediterranean Sea and up into Europe. And even a little research bears this out.

In the history of things, this area isn't too spread out.

Results from Family Tree DNA

It's important to understand that your DNA can be different than your sibling's DNA because of the somewhat random way in which it's passed down. You have 16 great grandparents, but you will not inherit an equal amount of DNA markers from each of them. That explains why I've got more Italian DNA than my own mother.

I received a great tip at a genealogy seminar that I'll pass along to you.

If you had your DNA tested somewhere, you should be able to download the data. You can upload that data to Family Tree DNA and have another way to connect with people who may be your distant relatives. Naturally they gave me different, and less specific percentages! Now I'm looking Turkish again, but hey. The Italians had to come from somewhere originally.

Collect the Whole Set!

It's been my experience that anyone who becomes involved in genealogy becomes obsessed with genealogy. We each have our areas of focus. Some people spend years trying to go back another generation in one troublesome branch of their tree. Others concentrate on the males only, climbing the tree one generation at a time. Me? I want everything. Everything!

When I started my tree, all I knew about my mother's father's family were his siblings' names (Eve and Noah to his Adam!) and that his mother might have been named Mariangela (she wasn't). But I wanted to know more. First I wrote to the webmaster for his town's website and he was kind enough to send me my grandfather's parents' names, birth dates and marriage date, as well as the birth dates of his siblings. Then I began ordering microfilm through the Family History Center of the vital records from his hometown in Italy.

Armed with my great grandparents' names and birth dates, I was able to locate their birth records and learn their parents' names. During that search I found other names that may have been siblings to my great grandparents.

That's when I knew I had to document all the records (1809–1860) for the entire town to see exactly how they all fit together. In the end, this long process yielded about 12,000 people for my family tree.

Twelve thousand people.

The whole time I worked on that project, which was about five years, all I kept thinking about was how much I wanted to do the same for my other grandfather's town—the town my maiden name comes from. But work got in the way, and I no longer had the freedom to go view microfilm at my local Family History Center during their limited hours. I kept hoping that my other grandfather's town's records would be digitized and made available on familysearch.org, but it didn't happen.

Then I discovered an Italian website that has the vital records for all of my ancestral hometowns! So now it begins again. I am meticulously downloading every single birth, marriage and death document from the town of Colle Sannita, ranging from 1809–1942 with a few gaps. That's a lot of documents.

As I download them, I make note of two key last names: that of my grandfather (Iamarino) and his mother (Pilla). Once I have them all I will begin:

• transcribing the basic facts into a spreadsheet,
• entering confirmed relatives into my Family Tree Maker file,
• piecing together every relative in the town.

Today my tree has more than 19,000 people. (I told you I'm obsessed.) After this project, I should hit 30,000. That's a great start, don't you think?

Case Study on "O Brother, Where Art Thou?"

Here's a lesson that supports my earlier post, "O Brother, Where Art Thou?" I have one branch of my family where the information was pretty scant. In fact, I never knew my great grandmother's maiden name was Caruso until the eve of my first trip to Italy—the trip that sparked my interest in genealogy. Later I heard from a distant cousin named Michael who was very interested in the Caruso family tree and shared a great deal of first-hand information with me.

As with any information I receive without documentation, I set about proving all of the facts Michael had shared with me, and in doing so, I learned quite a bit more facts.

My great grandmother, Maria Rosa Caruso, had at least four older brothers, all of whom came to upstate New York in the very early 1900s. Giuseppe came here first because each of this brothers' ship manifests says they were joining their brother Giuseppe at 827-829 Canal Street, Elmira, New York.

Maria Rosa's ship manifest was the hardest to find, and even after finding it, I was not sure it was the right Maria Rosa Caruso for quite some time. The manifest has some facts that are correct for her (born in 1880 or 1881 in Pescolamazza, and coming to join her brother Giuseppe), but it also has facts that do not work.

The manifest says she was married as of July 1906, but that doesn't work because I have her November 1906 marriage certificate from Hornell, New York. It also says her final destination is Addison, New York. While that is not terribly far from Elmira, or even Cameron, New York, which is another place her brother Giuseppe lived, I have no facts putting any members of this Caruso family in Addison. There is an address beneath her brother Giuseppe's name, but it appears to say "236 Bore". I can't make anything out of that.

I kept returning to this 1906 ship manifest and finally noticed something very important. Where the manifest shows an "m" for married, in much lighter ink there is an "s" for single overwriting the "m". (See the far-right side of the image.) So it was an error.

That left me with the troubling town of Addison. But in a web search today I discovered that Addison was the end of a particular railroad line that connected with the New York Central Railroad. So there is a good possibility that Maria Rosa had her ticket from New York City to Addison and then had to get on the Erie Railroad to get to her brother. At that time, Giuseppe lived in Cameron, New York, on a street parallel to the railroad tracks where he worked. I can see a railroad line on Bing Maps that runs from Addison to Cameron. And on her marriage certificate, Maria Rosa lists her residence as Cameron.

Now I feel as if the 1906 ship manifest finally makes sense. And this illustrates how important it is to gather as many provable facts as possible about your ancestor and their entire family.

Case Study on "Where Did Grandpa Come From?"

How to Find that Hometown

Let me share with you a case study that supports my earlier post, "Where Did Grandpa Come From?".  It details the steps I followed to find the true hometown(s) of my great grandmother's family—the Saviano family.

For many years I heard my grandmother and her siblings mention two towns: Pastene and Avellino. She and her siblings had heard those town names from their parents and repeated them throughout their lives.

It turns out they were slightly off. The family was from Avellino and Pastene the same way I'm from Rockland County, New York. That doesn't tell you what town I lived in, does it?

Pastene, ending in an E, is difficult to find. Plus, there's more than one Pastena, ending in an A, that could throw you off the trail. But I also knew the family was from the Benevento province, which borders the Avellino province. (A province in Italy is similar to a county in America.) In that area, there is a comune (municipality) named Sant'Angelo a Cupolo that contains a frazione (hamlet) called Pastene.

To put it more simply, Pastene is a tiny section of the town of Sant'Angelo a Cupolo. For proof that the Saviano family was from this place, I found their 1898 ship manifest when the whole family came to the U.S. They listed their hometown as "S. Angelo Cupolo".

Once I found the town on a map, this was perfectly legible to me.

I had never heard of that town before I found this document. At a later date, I found the New York City marriage certificate for my great grandmother's sister Filomena, and it listed Pastene, Italy as her birthplace.

But why did my relatives also say the family was from Avellino? Avellino is both a city and a province a few miles away from Pastene. My answer came from the World War II draft registration card for my great grandmother's brother Semplicio. It very clearly (albeit misspelled) lists his place of birth as Tufo in the province of Avellino, Italy.

Aha! Once I found that, I went to the Family History Center near where I lived at the time. Miraculously, someone had ordered a roll of microfilm from Tufo, so it was sitting there in the drawer!

On the microfilm I found the 1877 birth record for Semplicio Saviano. The big surprise was the 1875 birth record for an older brother no one in my family had ever known about. He died as a child. In fact, he had the same first name as another brother who was born later in Pastene: Raffaele.

So, although I haven't a clue why, this Saviano family moved from Tufo, Avellino, Italy, to Pastene, Benevento, Italy. A few miles was very far in those days, and my great great grandfather was not moving for a job.

And if you're thinking I may be looking at the wrong family in Tufo, I'm not. The mother in this family had the uncommon name of Colomba Consolazio, and that is seen very clearly on the Tufo birth records.

All of this is another example of the importance of locating as many documents as possible for your entire family.

Fan Out Your Search for Better Results

There's Donata's missing brother John!

Do you trace your direct-line ancestors only? Or do you explore other branches and in-laws when working on your family tree?

I believe strongly in gathering as much information as possible and presenting a more complete timeline for each family in your tree.

Most of my ancestors simplified my genealogy research by coming to America in a relatively short time span, and living within a few city blocks of one another.

Recently I was tracing one ancestor's sister through the years in census forms. In one census I found her brother Giovanni living with her. Giovanni had been missing to me, and he wasn't showing up in a search for his name.

If I hadn't been tracking his sister, I might never have found Giovanni.

This is also a good way to find a widowed ancestor.

When following the records for one of your great aunts or great uncles, you may find your widowed great great grandmother living with them. That helps narrow down the stretch of years when your great great grandfather died.

I guess you could say I prefer my family tree wide like a maple, not tall and thin like a spruce. Spread out and see how your family tree flourishes.
