How to Build a Professional-Quality Family Tree

I began writing this blog to encourage other genealogy hobbyists to take their family trees to a new level. My first several articles focus on the basics of a reliable, valuable family tree:

1. Gather multiple pieces of evidence for each fact. People make mistakes. It could be the census taker or the person providing information for someone's death certificate. Because of human error, one piece of evidence does not make proof.
2. Cite your sources. It's critical to be able to retrace your research steps. If you cite your source for a fact as the 1930 U.S. Federal Census, give the location right down to the sheet number, and provide a link to where you found it online, it's reproducible. If it's reproducible, it's more reliable.
3. Analyze your facts for discrepancies. My family tree has many people with the exact same name. I found a situation where I gave the same birth date to two different men with the same name. I needed more investigation to fix the error.
4. Ensure you're recording facts for the right person or people. For example, are you sure the census form you're looking at is for the specific family you think it is?
5. Research historical events as they pertain to your ancestor. One of my ancestor's hometown changed its name after World War II. If I hadn't discovered that, I wouldn't have been able to visit the town years ago. And I wouldn't be able to find the town's vital records today.

It all boils down to this: You've got to do the legwork. Do not trust information that falls into your lap. Use someone else's tree, for example, as a series of leads for you to investigate.

How Professional Genealogists Work

Professional genealogists follow a standard of proof to deliver accurate research to their customers. Maybe you've seen references to the Genealogical Proof Standard.

Let's look at how the five elements of this standard can improve your family tree research.

1. Conduct a reasonably exhaustive research. This goes back to my first point above of gathering multiple pieces of evidence. It also involves conducting searches that may not yield any results. For example, let's say you expected to find a family at a particular address in the 1930 census, but they're not there. To be thorough, you may need to go through every page in that census. If you still haven't found them, you may need to check out the surrounding enumeration districts.
2. Maintain complete, accurate citations to the source or sources of each piece of information. This was my second point above. You want to make your steps retraceable and show the quality of the sources. For example, the 1930 U.S. Census seems more reliable than "my cousin's father". Citing your sources can also show how many sources you've used. Several excellent sources make a fact very reliable.
3. Test your information. This relates to my third point above about analyzing your family tree for discrepancies. If you find an error, you may need to test the validity of one of your sources.
4. Resolution of conflicts among evidence items. This would be the logical conclusion to your analysis of discrepancies. When you resolve a discrepancy, make a note about the steps you took, and why you made your decision.
5. A soundly reasoned, coherently written conclusion. When you resolve a discrepancy or find something in your tree that you don't have a lot of confidence in, make notes. I like to flag questionable facts in my family tree by adding a bookmark (a feature in Family Tree Maker) and a note. This alerts me to facts with a lower level of confidence so I can treat them with the proper amount of faith.

You may not have the funds to hire a professional genealogist. You may prefer to do the work yourself because the hunt is what makes it so enjoyable.

But if you can adopt these practices, you can have a professional-quality family tree.

Here's Why Genealogists Love Immigrants

ID photo from a Petition for Naturalization

Last year my cousins' father passed away and I found his obituary. The man we called Doc is someone I've known since I was a little girl. But I didn't know anything about his family.

Genealogists know how to pull tons of facts from a well-written obituary. I documented Doc's family names and relationships in my family tree software.

Using these new pieces of information, I searched for his father Mario's arrival in the United States from Italy.

Mario's naturalization documents are among the richest I've found. Let's go through them to see how much you can learn about an immigrant ancestor through their naturalization papers.

Certificate of Arrival

When an immigrant wanted to become a citizen in the early 1900s, they provided information about their arrival into the U.S.:

Certificate of Arrival

• date of arrival
• port of entry
• name of ship

That's a boon to your family tree research right there. In Mario's case, the documents include a Certificate of Arrival that verifies these facts.

This certificate gives you, the family tree researcher, exactly the information you need to find Mario's ship manifest. There you can gather information that may include his father or mother's name and his town of origin.

Declaration of Intention

This form has so many vital facts packed into a small area. In Mario's case, we learn his:

• address
• occupation and age
• physical description
• town of birth
• birth date
• wife's name and date and place of birth
• wedding date
• children's names and birth dates

Mario's arrival information, confirmed on the Certificate of Arrival, is repeated here. Plus we see his signature and photograph.

Petition for Naturalization

Enough data to make a genealogist weep.

After filing a Declaration of Intention and going through the process, the immigrant completes another form. Mario's Petition for Naturalization repeats and supports the facts on his Declaration of Intention.

So if you are able to find one, but not both of these detailed forms for your ancestor, you've still found a genealogical treasure.

If your ancestor had a spouse and children at the time of their declaration and petition, you now have an official source of their vital information.

Mario's paperwork provided me with Doc's real name and birth date, as well as those of his brothers, whom I didn't know. With these facts I can fan out my search for census forms, Social Security Death Indexes, and other records of this family.

Perhaps most excitingly, I can search for documents from Mario's hometown in Italy and try to extend his family history there.

Naturalization records are available through the U.S. Naturalization and Records Administration (searchable online), Ancestry.com and FamilySearch.org.

The sheer density of critical vital information makes genealogists absolutely adore our immigrant ancestors.

Step-by-Step Discovery of My 5th Great Grandparents

It wasn't long ago that I discovered the maiden name of one of my great great grandmothers. (See This Expanded Resource Provided an Elusive Maiden Name.) It was a big deal when I learned her name was Maria Luigia. But it was amazing to learn her last name: Girardi.

My great great grandmother's birth record.

It was even more exciting to me as a Yankees fan! (For non-fans, the Yankees' manager was Joe Girardi for many years.)

Last night, while the Yankees were winning their game, I was at my computer. I was going through birth records from the online Italian archives. (See How to Use the Online Italian Genealogy Archives.) I was focusing on Maria Luigia Girardi's hometown of Pescolamazza—now called Pesco Sannita, Italy.

Her 1840 birth record gave me the names and ages of her parents: Gioacchino Girardi and Maria Teresa deNigris. I set Maria Teresa deNigris aside for the moment and worked to fill out this family more thoroughly.

First I looked for more siblings for Maria Luigia. I found Emidio born in 1843, Nicola Maria born in 1847, and Francesco Saverio born in 1851. Based on their parents' ages, there should be more children, both older and younger than Maria Luigia. But before finishing that search, I got excited to find her father Gioacchino's birth record.

My great great great grandfather's birth record.

There he was, my 3rd great grandfather, born in 1814. His parents, my 4th great grandparents, were Nicola Girardi and Maria Pennuccia. He was their first-born child, but I found several younger siblings by going year-by-year through the birth records for their town.

Sibling Giuseppe was born in 1815, Francesco Saverio was born in 1817, but apparently he died because another Francesco Saverio was born in 1822. Maria Rosa was born in 1825 and Pietrantonio in 1829.

Once I was confident I'd found their first-born child, I went in search of the marriage of my 4th great grandparents. The documents for marriages in 1813 in Pescolamazza are incomplete, consisting only of each couple's two declarations of their intention to marry.

Bingo! My fifth great grandparents—two sets!

But that was enough.

I found Nicola Girardi and Maria Pennuccia's declarations in February 1813. Each of these two documents contained the man and woman's parents' names.

There they were. Two sets of my 5th great grandparents from a branch I would never have discovered if I hadn't learned that previously unknown name of Girardi: Giuseppe Girardi and Serafina Orlando, and Carlo Pennuccia and Angela Verro.

During tonight's Yankees game, because I can't just sit on the couch all evening, I will search for more children born to these two couples. Their children will be my 4th great uncles and aunts. Having their names, and finding their children, will allow me to piece together a lot of the Girardi and Pennuccia documents from the town.

Finding the siblings is the only way to know how or if other people in this tiny town are related to me.

My experience in documenting the entire town of my grandfather taught me a lesson. (See Why I Recorded More Than 30,000 Documents.) If people have the same last name, and it's a very small town, and it's an era when relocating was not common, they're most probably related.

So go after those siblings. If you're searching records from the 1800s, remember that a woman might give birth nearly every year, and well into her forties. While many of the children will not live to adulthood, I personally treasure each one. And I'm so thankful to find them.

Back to the search!

Why I Recorded More Than 30,000 Documents

In 2007 I started ordering Italian vital records on microfilm from FamilySearch.org. The films were from the hometown of one of my grandfathers.

My first goal was to find birth records for my great grandparents to find out their parents' names. But so many people in the town had similar names it was comical. I wasn't sure I was looking at the right family.

There was only one solution. Record every single fact and plug them into my family tree software.

I did this for five years. Once or twice a week I spent a handful of hours with a computer open on my lap beneath the microfilm viewer. I developed my own shorthand: b, d, wed, bap, and Italian words like di and fu. I became incredibly fast at typing names like Mariantonia, Angelamaria, Francesco Saverio, Giuseppe, Giovanni.

More than 90% of the town is related to me!

Oh, did I mention I'm Italian?

This work was invaluable. I shared it online with anyone who may have ancestors from my grandfather's town of Basélice. I documented about 16,000 people, and about 15,000 of them are relatives by blood or marriage. Yeah.

Today Italian descendants are gleefully finding their ancestor's documents on FamilySearch.org or the Antenati website. Maybe you've been lucky and found your grandfather's birth record. Maybe you found your great grandparents' marriage record. But are you overlooking entire generations?

This year I used a simple app to download every document available from my ancestral hometowns. Now the organized images are on my computer (and a backup drive) awaiting my analysis.

I'm focusing on my mother's mother's branch first. Despite having grown up with cousins from this branch, I have the least information about them. I cannot get beyond my third great grandparents.

My first visit to Pastene, Sant'Angelo a Cupolo, Italy.

So here's the dilemma. The hometown of the families in this branch is Sant'Angelo a Cupolo, and specifically the smaller frazione within that town called Pastene. Only a limited amount of documents is available to me from the town. And one set of my great great grandparents was born in another town whose documents are not online.

The solution is going to be extensive, possibly exhaustive documentation of each birth, marriage and death record.

I've begun by finding every child born to my great great grandparents. I'm also documenting the children of my great great grandfather's brother.

The holy grail is that one magical document. The one that includes a baby's grandfather's name. The one that has a baby's maternal uncle as a witness. The one that names the father of a baby's grandmother who is reporting the birth.

I've got to look at each marriage record, too. There may be a marriage between a man and woman whose names I don't recognize. But maybe one is the grandchild of my ancestor. And maybe my ancestor's death record will be included.

Hopefully you enjoy the hunt as much as I do. Perusal of all available documents is the bare minimum.

Complete documentation…priceless.

Finding the Story Behind an Intriguing Family Photo

UPDATE: Publishing this story drew the attention of several of my relatives. We're now feeling a bit confident that my Uncle Army was in the Army Air Corps. His nickname had nothing to do with this. "Ame", which sounded like "aah may", is what my grandmother called him. It was short for Amelio (aah MAY lee oh). We kids thought it sounded like army.

My "Uncle Army", the photographer.

My earliest memory of my grandmother's brother—who we kids called Uncle Army—is posing for his camera. It was a large format camera that used glass plate negatives. It had a drape under which the photographer hid himself and his lens from the light.

I sat on a long upholstered bench in my great grandmother's home with my two siblings and my three first cousins. He took our portrait.

Uncle Army was a professional photographer in the Bronx. He took our communion photos, our confirmation photos, and our wedding photos.

He was a portrait photographer par excellence. Everyone acknowledged him as a true artist.

Serafina & Amelio Sarracino

So I was surprised to learn that Uncle Army, born Amelio Sarracino, enlisted in the army in 1943 at the age of 38. He was a married man with a gorgeous young wife, but he may have had a bit of wanderlust.

Due to his age, Uncle Army (that nickname is so ironic now) didn't fight for the military. He took photographs during his two-year stint.

None of my living relatives knows where Uncle Army was deployed or what he saw and photographed.

I found a book about the Signal Corps called "Getting the Message Through—A Branch History of the U.S. Army Signal Corps," by Rebecca Robbins Raines.

After the attack on Pearl Harbor, the Chief Signal Officer felt he needed "a variety of specialized companies to meet the needs of radio intelligence, operations, photographic duties, repair, depot storage, construction, and so forth."

I hope someday to find evidence of my uncle's World War II photography. Meanwhile, Uncle Army will always be the standard by which all other photographers are judged.

This story didn't give you any concrete family tree tips, but maybe you'll feel inspired. My inspiration was a genealogist's tweet about the stories our family photos can tell us.

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.)
