Genealogist Lynn Serafinn discusses 15 common ways we make mistakes in genealogy, and offers tips on how to separate fact from fiction in your family history.
It’s easy to get hooked on the act of discovery when researching our family histories. We love finding new people and adding them to our tree, and can often feel disappointed if our tree hasn’t grown after a hard day of research. But sometimes, our desire for growth can make us careless. Lack of rigour in our research can bring many errors into our precious family trees – from incorrect dates to the wrong people. This is especially the case when we are just starting out and less experienced, both in the subject matter (our ancestors) and the process of research itself.
Even when we are experienced, genealogy can be an informational nightmare. It’s bad enough trying to make sense of foreign, inaccurate or missing primary sources, but we must also contend with imperfect personal memories and simple human error. Then – with our trees and the trees of millions of others being freely available online – one mistake can become multiplied thousands of times over.
That’s why I wanted to write an article about how we family historians can get it very WRONG, if we’re not as meticulous as possible in our work. While some of this article will cover things specific to Trentini genealogy, most of the concepts I will share are applicable to ANY family history research, regardless of origin.
15 Ways We Make Mistakes in Genealogy
Mistakes are inevitable in genealogy, but they DO need to be addressed. The first step in dealing with them is to know where and how they most commonly happen. Here are some of the most common ways mistakes enter our family trees:
1. Relying solely upon people’s memories or family hearsay.
When we first start doing our family history, we typically begin with what we (and other family members) already know. The problem is, what we THINK we know may not actually be true, especially if we are talking about the past. Some examples:
- One of my father’s sisters wrote a very sweet love story about her parents’ early marital life (many years before she was born). In the story, she said they lived in Merano. The problem is, this is pure fiction. My grandparents never lived anywhere near Merano. My aunt made it up (probably because she had been born in the US, and had never actually visited Trentino). This colourful myth is still in circulation within the family, and it’s really difficult to get people to ‘unbelieve’ something after they’ve believed it so long.
- One of my clients gave me a death date for her great-granduncle. But the more I researched him, I could find no evidence to back up this date. When I asked where she had gotten this date, she told me someone in her family had given it to her, but she had no documentation for it. So, assuming this date was incorrect, I started my search from scratch. Eventually, I found the correct record – a good 20 years earlier than the date her relative had told her! To this day, we have no idea how the fictitious date was even conjured.
2. Copying or merging information from someone else’s tree.
Websites like Ancestry and MyHeritage are very enthusiastic about giving you ‘hints’ for your ancestors. Often these hints come from information in other members’ trees. The problem is, unless you know the person who made the tree, and have complete faith in their competence as a researcher, it’s a REALLY (really, really!) bad idea to copy that information onto your tree – especially if they have not cited any sources or provided any images of original documents. Furthermore, even if the information they have is 100% correct for THEIR ancestor, it doesn’t necessarily mean the ‘hint’ you’ve received is for YOUR ancestor. Merging people into your tree via these online hints is one of the fastest ways to compromise the quality of your work and turn your tree into a complete fiction. If you believe you’ve found the right person, manually copy the information into your tree, with accurate notes about who you got the information from, so you can verify it later.
Research is always a case of taking information from one source and writing it down in another place. For example, if you find a birth date, you have to enter it into your tree. It’s easy for a slip of the finger to result in a misspelled name or incorrect date, so careful proofreading before uploading your information is always the best policy. Reviewing your work regularly (an idea we’ll come back to in the next article) is another good habit to develop, as you’re bound to find typos lurking in places you may not have checked.
4. Lack of familiarity with the language.
If you’re unfamiliar with the language in which a record is written, it’s easy to get it wrong when you are trying to translate it. In Trentino, virtually all official documents before the mid-19th century (whether church or secular) are written in Latin. Later, they start to shift into Italian. Fortunately, you don’t have to be a Latin scholar or be fluent in Italian to make sense of most of the relevant details, but you do need at least some understanding of the language.
5. Lack of familiarity with the date conventions.
I’m not sure about the rest of Italy, but Trentino priests (especially in the 17th and 18th centuries) had a quirky method of writing dates that can confuse those who are unfamiliar. Have a look at these two baptismal records from 1669 and 1670, respectively, and try to make out the MONTHS in which they occurred:
CLICK IMAGE to see it larger.
CLICK IMAGE to see it larger.
In Figure 1, you’ll see the priest wrote ‘Xbre’ for the name of the month. If you remember Roman numerals, ‘X’ represents the number 10. So, you MIGHT assume ‘Xbre’ means October, the 10th month, yes? Well, you’d be wrong. ‘Xbre’ stands for DECEMBER, the 12th month. Why? Because the Italian word for ‘10’ is dieci. Although dieci MEANS ‘10’, it SOUNDS like the Italian word for December – dicembre. So, when you see ‘Xbre’ it is shorthand for December.
Figure 2 gives a similar example. The month is written ‘7bre’. This time the priest did not use a Roman numeral, but the regular (Arabic) number ‘7’. Again, you might thing this refers to the 7th month, i.e. July, but it doesn’t. In Italian, ‘7’ is pronounced sette, so ‘7bre’ is shorthand for the month of SEPTEMBER.
The last four months of the year are frequently abbreviated in this way (October is ‘8bre’ and November is ‘9bre’). The reason might have something to do with the fact that these months were originally the seventh, eighth, ninth and tenth months of the year; but given the fact that the current calendar was introduced much before the 17th century, I think it’s just the way the priests heard the words in their heads. But, if you’re looking at the words as numbers rather than hearing them as sounds, you could easily record the wrong month for your ancestor’s birthday.
6. Lack of familiarity with toponymy/geography.
Knowing the names of local parishes and villages (frazioni), as well as the names of contingent and more distance places in the region, is also an essential skill if we are to avoid mistakes in our family trees. I once saw a tree in which every child in the family was born in a different village, some of which were hundreds of miles from each other. While we in the 21st century may be accustomed to moving around frequently, this was less common in the past. This error happened because the man who made the tree was unfamiliar with Trentino and had no idea where places were on the map. Using an online database, he entered all the names he believed matched his search, but it was almost entirely incorrect. Good genealogists don’t just look up names and dates; they also take the time to learn about the places they are researching.
7. Lack of familiarity with the local surnames (and how they evolved over time).
When we start our research, we tend to look for information solely about our own family. This can cause us to develop ‘tunnel-vision’: we might find a record with something that somewhat resembles our family’s surname and assume it is our surname because we don’t know of any other surname like it. Here are some examples from my own research into a branch of my family with the surname ‘Gusmerotti’:
- The name ‘Gusmerotti’ was originally derived from the first name ‘Gosmero’ (the suffix ‘-otti’ meaning ‘big’). Thus, some very early records that say ‘Gosmero’ or ‘Gosmeri’ are typically predecessors of those who later called themselves Gusmerotti. When I first started my research, I failed to notice many of my early Gusmerotti ancestors’ records because the surname didn’t have the ‘-otti’ ending.
- Several years ago, when I knew little about surnames in my father’s parish, I found a record written in very small, tight handwriting, in which the surname started with a ‘G’, had ‘u’, ‘m’ and ‘t’ in the middle, and ended in a vowel (but I wasn’t sure if it was an ‘i’ or an ‘a’). At the time, the only name I knew that fit these parameters was Gusmerotti, and I thusly assumed it to be so. Later, I realised it actually said ‘Giumenta’ (which means ‘mare’), a surname that became obsolete sometime in 17th century, having evolved into the name ‘Martinelli’, and then ‘Martini’. In fact, Martinelli is more than likely a soprannome that ‘stuck’ over time (we’ll look at soprannomi next).
8. Not recognising a soprannome when you see it.
I’ve mentioned the use of soprannomi in other articles on this site. Soprannomi (plural of soprannome), are specific to Italian genealogy, including Trentino, and unless you get a handle on them, you can sometimes fail to recognise an entire branch of your family. A soprannome is used as a kind of ‘bolt on’ to a surname, to distinguish one branch of the family from another. Here’s a sample of a few soprannomi from my father’s parish of Santa Croce del Bleggio during the 16th-18th centuries, and the surnames of the families to which I have seen them attached:
|Bellotti (var. of Bella)||Caresani|
|Ferrari, Fabriferrari, Frerotti||Briosi|
While soprannomi can tell us a lot about who is related to whom, they can also cause many inexperienced researchers to make mistakes. This is because:
- Rarely do soprannomi bear ANY resemblance to the surnames.
- Soprannomi change frequently, typically lasting only one to three generations before they morph into something else.
- A priest will often use a person’s soprannome INSTEAD of the surname, when he records an event.
- Sometimes a soprannome will permanently replace the surname, which can make it seem like a family has fallen off the face of the earth.
- Many soprannomi are also surnames – but of OTHER families!
All these idiosyncrasies can cause you to miss one of your ancestors, attach someone to the wrong family, or assume you are looking at completely unrelated families. Unfortunately, the ONLY way to master the changes of soprannomi is to study the images of the original records of your family’s parish METICULOUSLY. There simply is no other way.
9. Misreading the handwriting.
Trying to understand handwritten documents can be a challenge even for the experienced genealogist, but it is especially difficult when you are new to research. Aside from the unpredictable spelling of names and places, and the frequent use of short-hand, sometimes the handwriting in the document is just plain MESSY! The only way to minimise mistakes caused by misreading handwriting is continual practice with images of original documents.
10. Overlooking the details.
Parish records often contain a lot of subtle information, which can be easy to miss if you read too quickly or not carefully enough. You might fail to notice ONE word indicating the fact that someone’s father was deceased, or that someone was a widow/widower when they married. A single word might indicate someone was NOT originally from the place they later lived, or that a godfather at a baptism was the brother of the mother of the child. Sometimes that single word is the only piece of information that will save you from months of fruitless – or inaccurate – research. Squeeze every bit of evidence out of your documents, and record every minute detail that tells the story of your family.
11. Drawing conclusions based on only ONE source.
Major mistakes can creep into our tree if we base our assumptions on information we’ve gathered from only one source (i.e. a baptismal, marriage or death record) without cross-referencing it to anything else. This happened to me when I was just starting out. I stumbled upon the death record for one of my 2X great-grandfathers, Bernardino Luigi Onorati. The record listed his date of marriage to my 2X great-grandmother, Margarita Elisabetta Gusmerotti. I knew from the baptismal record of my great-grandfather (their son) that Margarita’s father’s name was Lorenzo. I looked on the Nati in Trentino website and quickly found a Margarita Elisabetta Gusmerotti, daughter of Lorenzo, born in 1818. Happy I had found the right woman, and knowing the date of their marriage, I proceeded to research my new Gusmerotti line, spending many weeks on microfilm at my local Family History Centre. A few years later, I was in Trento and I suddenly realised I had never actually looked for the original marriage record of my Onorati 2X great-grandparents. As I now had access to digital images and my research abilities were vastly improved, I found the marriage record within minutes, rather than weeks. But when I read the document, my jaw dropped and I got a horrible sinking feeling in my stomach. The name of Margarita’s MOTHER was not what I had on my tree. Evidently, there were TWO different Margarita Elisabetta Gusmerottis, daughters of two different Lorenzos, and two different mothers, born around the same times. I had spent weeks (if not months) researching the WRONG families.
After I stopped kicking myself for not having checked earlier, I went to work. I found my TRUE 2X great-grandmother – Margarita Elisabetta Rosa Gusmerotti, born four years earlier in 1814. Then, I got to work building her lineage – with the new Lorenzo and my newly-found 3X great-grandmother. Happily, however, as I have been researching the entire parish for the past several years, I was able to link her lines to many other people I already had on the tree, and I quickly traced many of her lines back to the early 1600s.
12. Searching solely for your ancestor, instead of your ancestor’s FAMILY.
Have you ever taken a good look at your family tree, and think something along these lines?
‘Maria got married at 45 and her last child was born when she was 65 years old…hmmm…that doesn’t seem quite right….’
If not, you’re either really GOOD at catching mistakes, or you haven’t been careful ENOUGH in your research. Mistakes like these commonly happen when we find a record we believe to be our ancestor’s, and then STOP looking for anything else. Often, after we dig a little deeper, we might discover that the record we found was actually that of an older sibling who died when he/she was very young, for example. But because we want to feel like we’ve accomplished something after a day of research, it’s often tempting to tick off items on our ‘to do’ lists and move on to something else.
Fastidious researchers don’t just look for their ancestors – they look for their ancestors’ families. I think of it as ‘building families’ – births, marriages and deaths of everyone in the nuclear family of my ancestor. This gives me a much more accurate picture of who everyone is, and the relationships between them. It also minimises the chances that I will connect someone to the wrong spouse at another generational level.
13. Not recognising when the PRIEST has made a mistake.
It’s natural to want to believe parish records are 100% accurate, but unfortunately that is NOT the case. Parish priests may be dedicated to their spiritual duties, but they are also human. And like any other human being, they are prone to errors. Perhaps they miswrote a name because they heard it incorrectly, or they came from outside the parish and were unfamiliar with the local families. Maybe they didn’t have time to write it down carefully. Or, perhaps they felt it was unnecessary to specify every detail, as they assumed anyone reading the document would know who they were talking about. An example of this can be seen in the image of the baptismal record I used in title of this article, where the priest wrote ‘Matteo of Bono, notary’, omitting the surname ‘Onorati’. To him, it was obvious he was talking about Matteo Onorati; but to someone in the 21st century, it may not be immediately apparent, unless you are intimately acquainted with the records for that era.
Or (and this might surprise you), perhaps they simply couldn’t be bothered. While most priests are fastidious record-keepers, I get the distinct impression that some of them really couldn’t stand the obligation of having to write everything down. That’s when they got messy, took short cuts, left out information – and made mistakes. The only way to evaluate documents you suspect contain errors is to complete the architecture for a family as thoroughly as possible (as discussed in the previous point). That way, you can recognise inconsistencies and anomalies more easily, and make sure one person’s error doesn’t steer you off course.
14. Depending too much on transcriptions.
While parish priests might make their share of errors, it’s nothing compared to errors made when documents are transcribed by someone completely unfamiliar with the culture of the person whose information they are recording. Some perfect examples are US census records, ship manifests and Ellis Island immigration documents. In these, you have TWO levels of possible transcription error:
- First, when the government official writes the information into the document
- Then, when the website transcribes/indexes the document
For example, the Ellis Island immigration documentation for my grandfather lists his village of origin as ‘Dunendo’. One of my cousins put ‘Dunendo’ on his tree, and wrote to me asking where it was because he couldn’t find it on the map. The problem is, ‘Dunendo’ doesn’t exist; the name of the village is Duvredo. The transcriber misread the handwriting, and the mistake then became ‘fact’.
Census records are also notorious for incorrectly spelled names and incorrect ages. If you are depending upon these kinds of ‘official’ documents for information, use them with a pinch of salt, and NEVER assume transcriptions are accurate.
15. Depending too much on ‘Nati in Trentino’ or other online databases.
In this digital era, we are used to ‘Googling’ everything. We want to do quick searches and find information right away. The problem is, to make things searchable, they must first be transcribed from other sources, and then filtered to respond to specific search parameters.
We’ve already looked at the problems transcriptions can bring with them. Fortunately, the database on the Nati in Trentino website (see my previous article ‘Searching Online for 19th & 20th Century Trentini Ancestors’ about this site) is very WELL transcribed, making it fairly reliable for 19th century searches. However, you still have the limitations of what it DOESN’T show because it’s not included in its search parameters. For example, you cannot see the names of grandparents or godparents. You cannot see if a priest has made a notation that the child died shortly after baptism. Many people use Nati in Trentino when they first get started researching their Trentini ancestors, but it is a mistake to rely upon it as your sole source of information, because it will likely create errors in your tree.
Errors are also likely to occur if you depend too much on the Family Search website. There, many Italian parish records have been transcribed by volunteers. These volunteers can only choose which parishes Family Search happens to be currently working on. Thus, it is highly likely the volunteers will be unfamiliar with the parishes whose records they are transcribing. There are many rules on how Family Search want the documents transcribed, which I found frustrating when I gave it a shot a few years ago. I stopped volunteering because I strongly felt these limitations create problems for the people using the database.
The main difference between a good genealogist and a mediocre one is not how many mistakes they make, but how rigorously they stay on top of them. A good genealogist develops a research routine and standards that help ensure mistakes get FIXED quickly, and that all information can be verified by some form of documentation. To do this, you need to cultivate two essential habits:
- CONTINUOUSLY REVIEW YOUR WORK. No matter how long you have been doing genealogy, it’s unwise to take anything for granted. Your earlier work may contain errors you never noticed, or never addressed. Over the years, you may have inadvertently compounded these by assuming one thing to be true that wasn’t. Look for gaps, inconsistencies and conflicting information. Check, check and triple check. Next year, check it all again.
- ALWAYS CITE YOUR SOURCES. Source citations are like genealogical ‘breadcrumbs’. They enable you to trace back to where you found information and verify whether your conclusions are true. They also give other people confidence that your information is correct. Lastly, they give clues that point you in the right direction to find records or other family members. Even if your only source is a specific titbit is family hearsay, a phone call or a personal letter, always cite who gave you the information, and how/when you received it.
In my next article, we’ll look specifically at citing sources – how to do it, why to do it, and how to use citations to back up HYPOTHESES you can formulate, even when the precise information may be missing.
