The Larson surname means “son of Lars”, and Lars is the Scandinavian form of Laurence. It is chiefly Swedish, Norwegian after that, and the spelling most Americans carry today was simplified on this side of the Atlantic.
What Does the Surname Larson Mean?
Larson means “son of Lars”. Lars is the Scandinavian short form of Laurentius, the Latin name that gives English its Laurence and Lawrence, so a Larson is literally the son of a man called Laurence.
Laurentius itself is older and less certain. The standard reading is “man of Laurentum”, after the ancient town in Latium south of Rome. A second tradition connects it to Latin laurus, the laurel, the wreath worn by victors, and that association was already attached to the name in the Middle Ages. Scholars generally treat the Laurentum derivation as the likelier of the two and the laurel as a later gloss, but neither can be proved, and honest sources give both.
What is certain is the second half. The -son ending is not decoration. It is a statement about one specific man in one specific generation.
Where the Larson Name Comes From
The Larson name comes from Sweden above all, and from Norway and Denmark after that. It is a patronymic, built from a father’s given name rather than a farm, a trade or a nickname, so unlike most European surnames it has no home parish and no founding family.
Saint Lawrence and the making of Lars
The name arrived in the north with the Church. Lawrence was a deacon of Rome martyred in 258, and he became one of the most widely venerated saints in medieval Scandinavia, known in Swedish as Sankt Lars.
The scale of that devotion is easy to see in stone. Lund Cathedral, consecrated to Saint Lawrence and made the seat of an archbishop in 1104, was for a time the mother church of the whole of Scandinavia. Parish churches were dedicated to him at Söderköping, at Falkenberg and in dozens of towns besides.
Boys were named for the saint accordingly. By the early modern centuries Lars was among the most common male names in Sweden and Norway, which meant that in every parish there were sons of a Lars waiting to be identified.
A name that changed every generation
For most of Scandinavian history these were not family names at all. A man called Lars Nilsson had a son who was Per Larsson, whose own son was Anders Persson, and the surname turned over with every birth. Daughters took -dotter or -datter instead.
The system was only frozen into hereditary surnames by law and custom in the nineteenth and early twentieth centuries. That story, and the acts that ended it, are told in full on our page for the Olson surname.
Larsson, Larsen, Laursen: one name, three countries
The ending tells you the country. Sweden used -sson, giving Larsson. Denmark and Norway used -sen, giving Larsen. Jutland preferred the local form Laurs, which produced Laursen, along with Lauridsen and Lauritsen from the fuller Laurits.
All three remain heavyweight names at home. Larsson is the sixth most common surname in Sweden, carried by roughly 135,000 people. Larsen is the fourth most common in Norway, with about 36,000 bearers, and the seventh most common in Denmark, held by around 2.4 per cent of the population. The same national split runs through the whole family of Nordic patronymics, as our page on the Hansen surname sets out.
Spelling Variants and Related Names
The main variants are Larsson (Swedish), Larsen (Danish and Norwegian), Larson (American), Larssen, Laursen, Lauridsen, Lauritsen and Lauritzen. All descend from Laurentius by way of a local short form of the given name.
Larson is the American simplification. Double consonants were routinely reduced in the United States, and the second s in Larsson served no purpose to an English-speaking clerk, so it went. A great many Norwegian families with Larsen made the same journey in a different direction, shifting the Danish-Norwegian -sen to the more American-looking -son and landing in the same place.
The given name behind them all has its own crowd of forms: Lars, Lasse and Lars-Erik in Sweden, Laurits and Lauge in Denmark, Lárus in Iceland and Lauri in Finland. Cognate surnames elsewhere include Lorenz and Lorenzen in Germany, Laurens in the Netherlands, Lorenzo in Italy and Spain, and Lawrence and Lawson in England.
Do not overlook the female forms. Larsdotter and Larsdatter were as common as their brothers’ names in Swedish and Norwegian parish books, and it is worth searching for them, because in America the distinction was almost always dropped and daughters simply became Larsons too.
The Larsons in America
Larsons came to the United States in the great Scandinavian emigration between the 1840s and the 1920s, most of them Swedes, and they went overwhelmingly to the Upper Midwest. Around 1.3 million Swedes and some 800,000 Norwegians left in that period, the latter representing one of the highest emigration rates in Europe, second only to Ireland’s.
The 2010 US Census makes the anglicisation visible. There are 122,587 Larsons in America and only 1,238 Larssons: ninety-nine to one. Larsen, by contrast, survived largely intact, with 55,960 bearers against 1,798 Laursens. The Swedish spelling was abandoned almost completely, while the Danish and Norwegian one was largely kept, and the difference is one of the clearest surname fingerprints of how the two migrations behaved.
Illinois took the first great wave. Chicago’s Swedish colony was the largest outside Stockholm, and the machine shops and furniture factories drew thousands north-west to the mills and foundries that made Rockford a Swedish city in everything but name. Minnesota followed, absorbing more than a quarter of a million Swedes between 1850 and 1930, and Minneapolis grew a Scandinavian quarter around the boarding houses and halls of Snoose Boulevard.
Norwegian Larsons and Larsens concentrated in Wisconsin and Iowa, farming the coulee country in villages like Mount Horeb. Swedes pushed on to the plains, taking homesteads on the Nebraska prairie at Stromsburg and across the eastern Dakotas from the 1870s.
Two later currents carried the name further. One ran east to the wire mills and machine shops of New England, where Worcester built one of the largest Swedish communities on the Atlantic coast. The other ran west, to the fruit ranches of the San Joaquin Valley at Kingsburg and to the timber and fishing towns of Puget Sound, where Norwegians founded Poulsbo on water that reminded them of home.

Frequently Asked Questions
What does the surname Larson mean?
Larson means “son of Lars”. Lars is the Scandinavian form of Laurentius, the Latin name behind English Laurence, usually explained as “man of Laurentum” and sometimes linked to laurus, the laurel.
Is Larson Swedish or Norwegian?
Most often Swedish. Larson is the American spelling of Swedish Larsson, and Sweden sent by far the largest number of bearers. Norwegian families are well represented too, usually arriving as Larsen and changing the ending in America.
Where does the Larson family come from?
There is no single Larson family. Because the name is patronymic, thousands of unrelated households across Sweden, Norway and Denmark took it independently, each simply naming a father called Lars. Two Larsons sharing a surname need share no ancestor at all.
How common is the surname Larson?

Is there a Larson family crest or coat of arms?
No. In every European heraldic tradition, arms are granted to an individual and pass to that person’s direct descendants, never to everyone who happens to share a surname. For a patronymic like Larson, borne independently by thousands of unconnected families, the idea is doubly meaningless. Any site selling you a “Larson family crest” is selling a decoration, not a lineage.
What is the difference between Larson, Larsson and Larsen?
The endings mark the country. Larsson is Swedish, Larsen is Danish and Norwegian, and Larson is the American form of either, most often of Larsson. Laursen and Lauritsen are Danish variants built on the local forms Laurs and Laurits.
If your family carries the Larson name, its route from Scandinavia to America is traceable. Atlas of Home can follow it from the parish register that first recorded a son of Lars to wherever your family landed, and to wherever you are now.
