Swedish Name Changes and Patronymics in Your Family Tree

Do you have patronymics in your family tree? This is likely the case if you see constant changes of surnames between generations. In this blog, you will find information about what patronymics are, their use over time, and an effective strategy to overcome them in your genealogy research.

What is Patronymics?

Patronymic surnames were the norm for centuries in Sweden. If you have Swedish ancestry it is therefore highly likely that you have patronymics in your family tree. In this blog, we look into the evolution of patronymics over time. Unlike fixed family surnames, people were identified by their father’s first name followed by the suffix “-son” for sons or “-dotter” for daughters. For example, if Lars Eriksson and Maja Jönsdotter had a son named Erik, the son’s name would be Erik Larsson. If he had a daughter named Karna, her name would be Karna Larsdotter. 

 

If Karna then married Pär Andersson, they would keep their respective surnames while their children’s last names would be Pärsson or Pärsdotter. As a result, the people a single nuclear family could have at least three or four different surnames. There could be even more variations of surnames if additional fathers, mothers or perhaps foster children were added to the family over time. 

Patronymics: A Practice From Medieval Times

The patronymic tradition made surnames change with each generation. This was a practice that dated back to at least the medieval times and the reign of King Gustav Vasa (also known as Gustav Eriksson Vasa) in the 1500s. The system applied across all social classes. Fixed surnames were very uncommon. If you encounter a fixed name in your family tree from those days, it might indicate origins outside Sweden. 

 

Surnames in Sweden at that time could also be a title reflecting the person’s profession, such as Olof Bagare (Baker), or Johan Skräddare (Tailor). By the 1500s-1600s, many priests had also had taken fixed names, of which many ended in “-ander” and “-us”, such as Wallander and Bergius. In addition, soldiers were given last names when they joined the military to tell them a part from each other. Their names could be adjectives that reflected their character such as Fast (Firm), Frisk (Healthy), and Rask (Brisk).

Evolution of First Names

During the reign of Gustav Vasa’s grandson, Gustav II Adolf, in the 1600s, first name practices in cities began to change. Noble families started giving their children more than one first name. They were inspired by the name of the King Gustav II Adolf and the burghers soon followed suit. 

 

Eventually, the practice of giving children multiple first names spread to the countryside. That was where the vast majority of the Swedish population lived as farmers. Around the same time, the nobility also began adopting fixed surnames. The practice of adopting fixed surnames, as well as multiple first names, can prove beneficial for your family research.

Devolution of Patronymics

By the late 1800s, more people were adopting fixed surnames. This may be good for you research. However, it can also add to the challenges of overcoming patronymics in your family tree. You then have to determine that it is the very person you are researching that changed names. There were no regulations on how to change a name at that time. All a person of legal age had to do was to tell the parish priest that they, and/or a family member of theirs, wanted to change their name. You will often find a note of that in a church record or other. 

 

Although it was easy to take a fixed name, the patronymic system persisted well into the 1900s. It wasn’t until 1966 that a law officially ended the use of patronymics in Sweden. However, already in 1901, a regulation encouraged Swedes to adopt fixed surnames. As a result many took their father’s patronymic name as their fixed family surname or chose an entirely new one. These new surnames were often inspired by the places they lived, such as Westman (man from the west), or by nature, such as Lindgren (linden branch).

What To Do With Patronymics in Your Family Tree?

The patronymic naming system in Sweden can pose challenges for genealogy research. However, it also offers a unique advantage: a surname often reveals the father’s first name, providing valuable clues. The key to navigating patronymics successfully is correctly identifying the first individual in your family tree. Once you establish this person’s identity, tracing earlier generations becomes much more manageable.

Sweden has a long tradition of maintaining detailed population records, which greatly supports genealogical work. Still, no matter how good the records are, starting with the wrong individual can lead your research in the completely wrong direction. A reliable strategy for identifying this crucial first person is to focus on their birth details—when and where they were born—rather than relying solely on their name. This approach helps overcome the complications of patronymic naming.

Where to Start When Tracing Swedish Ancestry

Tracing Swedish ancestors can feel overwhelming. A common piece of advice is that you need three basic pieces of information to get started: a relative’s name, date of birth, and their birth or residence parish in Sweden. That advice can discourage some people from even trying. What if you do not have all of that information? In this blog, I explain why these facts are important for in-depth genealogical research – but also why you do not necessarily need to know all of them to begin.

The Three Basic Pieces of Information

Name

Knowing a first and last name is a good starting point. However, many Swedes changed their names after emigrating. Some did so to make the name easier to pronounce. Others changed their names to better fit into their new country. For example, “Anders Åkerman” might have been changed to “Andrew Ackerman” or “Andy Oakerman.” “Maria Eriksson” could be spelled “Mary Ericson” or “Marie Erickson.”

 

 

In the late 1800s, many Swedes began adopting fixed surnames in Sweden. In 1901, a regulation was introduced requiring people to have a permanent surname. After that, changing one’s name required official permission. Before 1901, it was usually enough to simply go to the priest and state that you wanted to change your surname – and you could pretty much choose any name, as long as it was not one from the nobility. These name changes can make it more challenging to trace your Swedish ancestry, especially when searching for relatives who emigrated or changed their names for other reasons.

 

Birth Date

A date of birth is often crucial for distinguishing between people with the same name. Sweden used patronymic surnames for centuries. This tradition resulted in many people sharing identical last names – such as Karlsdotter or Nilsson – without being related. For example, there could even be several “Per Nilsson” or “Annika Karlsdotter” born in the same parish during the same decade. An exact date of birth helps identify the correct person in historical records. Fortunately, Swedish church books recorded dates of birth carefully, making them an invaluable source for genealogical research.

 

Parish

Swedish genealogy relies heavily on church records, much like census registers do in Canada and the United States. Each parish kept detailed annual records containing information about parish members’ names, births, marriages, deaths, and more. In addition, church books often include details about where a person came from and where they moved. This makes it possible to track individuals from one parish to another over time. Knowing an ancestor’s birth or home parish is therefore important, because church records were kept locally. Without information about your ancestor’s parish, it can be difficult to find the right person.

Other Sources Than Can Help You Get Started

Du behöver inte ha alla tre uppgifter (namn, födelsedatum, församling) från början. Det finns många sätt att hitta dem under släktforskningens gång. Här är några exempel från mitt eget arbete:

  • Familjehistorier: En person jag gjorde släktforskning åt sa: “Det här låter kanske konstigt, men min farfar sa att vi kom från masklandet i Sverige.” Det visade sig syfta på Värmland – en ledtråd som, i kombination med andra, ledde rätt.

  • Fotoalbum: Gamla foton med namn, datum eller fotografens ort kan ge viktiga pusselbitar. Jag har identifierat många individer och familjer i svenskamerikanska fotoalbum genom att analysera just dessa detaljer.

  • Släktträd: I ett annat släktforskningsprojekt visade sig ett befintligt släktträd vara korrekt fram till en farfarsfar som emigrerat. Därefter innehöll trädet fel personer. Med hjälp av två namn på syskon till huvudpersonen vi sökte kunde jag identifiera rätt familj i Sverige. 

The lesson is that every detail counts—a name, a postcard, a sibling’s birthdate, or an emigration year can be the key to a breakthrough. And if traditional genealogy using historical records doesn’t provide enough information, DNA testing can also offer additional insights.

DNA as a Complement or Starting Point

DNA tests can be an excellent complement to traditional genealogy and, in some cases, a good starting point. 

DNA as a Complement to Genealogy Research

Historical records in Swedish genealogical archives are generally well-preserved. However, there are cases where information is missing or was recorded incorrectly. In some instances, fires, people discarding “outdated” archives, or water damage have resulted in documents being lost or difficult to read. DNA can help confirm family connections when documentation is incomplete, unclear, inaccurate, or missing. Through DNA matches with people who share a common ancestor with you, it is often possible to verify relationships that would otherwise be difficult to prove. DNA is especially useful when tracing Swedish ancestors who emigrated without leaving much documentation behind.

DNA as a Starting Point to Genealogy Research

The greatest value of DNA tests lies in the ability to connect your family tree with others through the DNA matches that are presented. The test can provide information about which individuals you and your matches are likely descended from in common. However, for this to be possible, the shared ancestor must not be too far back in time. The further back in generations, the less likely it is that you have inherited enough comparable DNA to compare with relatives living today who have taken the test.

 

By analyzing DNA matches, you may also be able to find relatives who have progressed further than you in their genealogical research. By studying their family trees and contacting them, you may gain valuable information that can help you move forward -such as names, dates of birth, or parish affiliations. Many DNA testing companies also offer ethnicity estimates that may indicate Scandinavian or Swedish ancestry. However, these estimates should be interpreted with caution, as they can be misleading, especially when the percentages are low.
