Hansen

Hansen is not a family name in origin. It is a sentence about one man: Hans's son. Hans is the everyday short form of Johannes, the name English turns into John, and for most of the history of Norway and Denmark the -sen on the end was not inherited by anybody. It was a live description, attached to a particular boy because of a particular father, and it expired with him. In Norse custom the ending -son, later written -søn and then -sen in Danish, Norwegian and German, was fixed to the genitive of the father's given name to mean son of; a daughter took -datter in Danish and Norwegian, -dotter in Swedish and Norwegian, -dóttir in Icelandic and Faroese. Swedish kept the father's genitive -s in front of the suffix, which is why Sweden has the doubled Johansson and Andersson where Denmark and Norway have the single Johansen and Andersen. That one letter is still the quickest way to tell a Norwegian or Danish name from its Swedish cousin at a glance.

The consequence is the part that surprises modern readers. Under the old system a family did not share a surname. If Hans had a son called Peder, the boy was Peder Hansen. If Peder had a son called Anders, that boy was Anders Pedersen, not a Hansen at all, and Anders's daughter was Andersdatter. The name moved down the generations like a wave, never the same twice, and it carried no information about kin beyond a single step. The Dane Thomas Hansen Kingo is a clean specimen of the machine at work: he was the son of Hans Thomsen Kingo, so his own patronymic was Hansen while his father's was Thomsen, and the two men would have looked to a clerk like members of two different families. The Norwegian Peder Claussøn Friis works the same way, son of Nicolas Thorolfsen Friis, Claus being the everyday short form of Nicolas.

So when a Hansen is told the name means nothing much (just son of Hans, and there are hundreds of thousands of them), the honest answer is that it is not a blank. It is a fossil: the last frame of a naming system that ran in Scandinavia for centuries, stopped by a dated act of law you can point at.

The patronymic alone was never quite enough, because in a parish with two Peder Hansens it settled nothing. So a third name was often added, a byname taken from a place or from something about the man himself, and it is that third element rather than the -sen that behaves like a modern surname. Both the men above carry one (Kingo in the Danish case, Friis in the Norwegian), set after the patronymic in the order given name, patronymic, byname. Over generations such a byname could harden into an inherited family name while the patronymic in the middle went on changing, which is why Early Modern Scandinavian records are full of men with three names of which only the last is stable.

This explains what did not happen to Hansen. A family that took a farm or a locality as its third name ended up with a name pointing at a place on the map. A family that never took one, or let it lapse, reached the 19th century with nothing but the patronymic to freeze, and the patronymic is what got frozen. Names like Hansen are common today partly because they belonged to the households with no other candidate: the ordinary population of two kingdoms that had never needed a hereditary name, because everyone in the parish already knew whose son you were.

The freeze did not arrive everywhere at once, and it did not arrive for everyone at once. It came to the top of society first, by decree. In 1526 King Frederik I of Denmark-Norway ordered that noble families take up fixed surnames, and a good many of them simply reached into their own heraldry for one. The Rosenkrantz family, rose wreath, took their name from the wreath of roses that formed the torse of their arms. The Gyldenstierne family, golden star, took theirs from the seven-pointed gold star on their shield. From that year a Danish or Norwegian nobleman had a name that belonged to his house and passed to his children unchanged.

Everyone else went on as before, and there is a single scene that shows the two systems standing in the same room. The homage of 1591 at Akershus Fortress records who counted as Norwegian nobility at the end of the 16th century: some Danes, bearing the fixed heraldic names Gyldenstierne, Lange, Juel and Huitfeldt; some Norwegians, such as the Benkestoks; a couple of foreigners, the Scottish Mowat and the French Norman de la Navité; and approximately thirty Norwegians who had no such name at all, only patronyms ending in -sen. Half the room had surnames in the modern sense and half the room had their fathers' names. If you carry Hansen, your ancestors were in the second half.

The gap was enormous by European standards. By 1400 most English families, and those of Lowland Scotland, had already adopted hereditary surnames; the Danish and Norwegian commons would wait another four hundred and fifty years. Even inside the nobility the old habit died slowly. King John ennobled Eggert Eggertsson, Lawspeaker of Viken, in 1488; his son was Hans Eggertsson, a city administrator of Bergen recorded in 1522; that man's son was Eggert Hansson, Lawspeaker of Iceland, active between 1517 and 1563. Three generations, three different last names, in a family the crown itself had raised, with a Hansson standing in the middle of it.

Then the state intervened, and it can be dated. The Danish government outlawed the old practice in 1856: from that point a Dane's last name was to be inherited rather than made fresh each generation, and whatever patronymic a family happened to be carrying in that decade became the name of everyone descended from it. Norway followed later. The Norwegian parliament passed a family name act in 1923, and the reasoning recorded for it is unromantic and entirely practical: a rising population, and the need to end the confusion of a new set of last names in every generation. Across the turn of the 20th century the patronymic was converted, country by country, into a family name inherited unchanged by sons and daughters alike, so that -sen ceased to mean son of anybody and simply meant this household.

The rest of the Nordic world moved on its own timetable. In Sweden, children keeping the father's patronymic as a fixed surname appears in the 18th century but only becomes usual in the late 19th; Swedish patronymics were abolished in 1966, partially restored in 1982 for anyone willing to apply and pay a fee, and since 1 July 2017 Swedish parents may give a child a patronymic at birth again. Finland made family names compulsory by law in 1920. The same wave had broken elsewhere in Europe on other dates: Napoleonic annexation gave the Netherlands a register of births, deaths and marriages in 1811 and forced the Dutch to adopt distinct surnames, and the Welsh ap system was ground down after the Act of Union of 1536, turning ap Hywel into Powell and ap Rhys into Price.

Norway's timing carries an extra edge. The 1814 Constitution forbade the creation of any new nobility, and the Nobility Law of 1821 began winding up the noble estate altogether, the last legally noble Norwegians dying in the early 20th century. Norwegian farmers had always been comparatively free (the country never had a large or strong aristocracy), and from the middle of the 18th century, peaking in the 19th, great numbers of them bought the farms they worked. So the 1923 act handed permanent hereditary surnames to a nation that had just finished abolishing its hereditary lords. What a noble house received by royal order in 1526, a farming family finally received by act of parliament four centuries later.

Freezing a patronymic system produces a very particular result: the surname stock of a whole nation collapses to the number of given names that happened to be fashionable among one generation of fathers. Hans, being the everyday Johannes, was one of the commonest of them all, and the arithmetic shows. As of 2008 Hansen was the third most common surname in Denmark, borne by 4.3 per cent of the entire population. As of 2016 it was the single most common surname in Norway, and that is before counting the variant spellings such as Hanssen, which are themselves common. In the Faroe Islands it ranks second. In the north German states of Schleswig-Holstein and Hamburg it ranks third and fifth respectively. In Sweden the parallel form, built on the same father with the Swedish genitive, is Hansson.

The Danish state itself conceded that the pool was too small. Having outlawed the old practice in 1856, it had to ease the regulations again in 1904 precisely to deal with the limited number of patronymics in circulation: too many people, too few names, and a registry choking on them. Iceland's parliament debated the identical arithmetic from the other direction: one of the arguments made for adopting family names there was that a mid-19th-century Iceland in which one in six males was called Jón made it very hard to tell people apart at all.

So Hansen is common for a reason that is itself a piece of history. It is not common because it was vague, or because clerks were careless. It is common because two kingdoms ran a naming system that never intended surnames to exist, then converted an entire population to hereditary names in a single legislative stroke, at a moment when a very large number of fathers were called Hans.

The clearest way to see what Hansen used to do is to look at the one Nordic country that never made the change. Iceland never formalised a system of family names, and its naming law still requires the old practice, with a handful of exceptions. A man named Jón Einarsson has a son, Ólafur; the boy is not Ólafur Einarsson like his father but Ólafur Jónsson, Jón's son. Jón's daughter Sigríður is Sigríður Jónsdóttir. An Icelandic household therefore contains several different last names as a matter of course, and nobody finds this odd.

Everything downstream follows. Icelandic telephone directories are alphabetised by first name and list professions to tell people apart. Icelanders address one another by given name: the former prime minister Jóhanna Sigurðardóttir was never Ms Sigurðardóttir, and Björk, whose full name is Björk Guðmundsdóttir, is simply Björk to every Icelander. Where two men shared a given name and a father's name alike, the traditional fix was to reach back a generation and add the grandfather's (Jón Þórsson Bjarnasonar against Jón Þórsson Hallssonar), a device that appears all over the sagas. Where the mother's name is used instead the grammar is the same: the footballer Heiðar Helguson is Helga's son, the novelist Guðrún Eva Mínervudóttir is Minerva's daughter, and the medieval poet Eilífr Goðrúnarson carried a matronymic a thousand years ago. Elsewhere in Scandinavia a matronymic was exceptional, used when a child was born out of wedlock or the mother was far the better known parent, as with Sweyn Estridsson.

Iceland had the same argument Denmark and Norway settled by law, and settled it the other way. Icelanders who studied abroad began bringing back inherited family names in the second half of the 19th century: 108 such names existed in 1855, and 297 by 1910. The Althing legalised their adoption in 1913, then banned new ones in 1925, on the grounds that they were not authentically Icelandic, that -son endings made a family name indistinguishable from a patronymic, and that anyone could help themselves to the name of a well-known family. Since 2019, Icelanders registered as non-binary may use the suffix -bur, child of, in place of -son or -dóttir. The system is old and still being amended, which is exactly what Hansen would be doing had 1856 and 1923 gone differently.

Hansen travelled. Its frequency outside Denmark, Norway and Schleswig-Holstein is the work of Danish emigration, and many of the families who left did so before the naming laws had finished their work at home. That produced a quiet irony: the emigrants froze their names first. A Nordic family arriving in a country that expected a fixed hereditary surname simply kept the patronymic of the first ancestor to make the crossing, permanently, for everyone below him, as the Icelandic community in Manitoba would later do, and as the Danish and Norwegian parliaments got round to legislating decades afterwards. If your line left early, the man whose name you carry may be the exact ancestor who boarded the ship.

The other thing that happened on arrival was spelling. Nordic immigrants to English-speaking countries frequently anglicised Hansen to Hanson to fit English orthographic rules, so a line that reads Hanson on an American headstone and Hansen in a Danish parish register has not changed families, only clerks. The North American bearers cluster where Scandinavian settlement went: Bertha Lee Hansen and Charles Robert Hansen in Minnesota, Dave Hansen and Connor Hansen in Wisconsin, Clifford Hansen in Wyoming, James V. Hansen in Utah, George V. Hansen in Idaho. Canada has Colin Hansen in British Columbia, the astronaut Jeremy Hansen, and the paraplegic athlete and humanitarian Rick Hansen; Ian Hansen was a Falkland Islands politician. The name went where the ships went.

For a name with no coat of arms behind it, Hansen has done conspicuously well in the sciences. The Norwegian physician Gerhard Armauer Hansen, 1841 to 1912, discovered the cause of leprosy, which is why the disease carries his name to this day. The Dane Emil Christian Hansen, 1842 to 1910, was a fermentation physiologist. Peter Andreas Hansen, 1795 to 1874, was a Danish astronomer and Julie Vinter Hansen, 1890 to 1960, another; Hans Jacob Hansen, 1855 to 1936, was a Danish zoologist; Per Brinch Hansen, 1938 to 2007, a Danish computer scientist. The climatologist James E. Hansen and the economists Alvin Harvey Hansen and Lars Peter Hansen carry the name in the same tradition on the American side of the Atlantic.

In public life, H. C. Hansen was Prime Minister of Denmark from 1955 to 1960; Even Hansen, 1790 to 1840, was a Norwegian civil servant and politician of the constitution's first generation; Urban Hansen and Eva Kjer Hansen came later in Danish politics. Helmer Hanssen, 1870 to 1956, was a Norwegian polar explorer, and Percy Hansen, 1890 to 1951, a Danish recipient of the Victoria Cross. Theophil Freiherr von Hansen, 1813 to 1891, was a Danish-Austrian architect; Georg Emil Hansen, 1833 to 1891, a Danish photographer; Mogens Herman Hansen, 1940 to 2024, a Danish classical philologist.

The name is loud in sport as well: the Danish handballer Mikkel Hansen, the Danish footballer John Hansen, the Scottish footballer Alan Hansen, the New Zealand rugby coach Steve Hansen, the Danish chess grandmaster Curt Hansen, the Australian cyclist Adam Hansen, the Faroese footballer Abraham Løkin Hansen. None of them are kin to one another in any traceable way, and that is the point. A Hansen is not the member of a clan with a chief and a seat. A Hansen is the inheritor of a system, one that made a fresh name for every man born into it, until the Danish government stopped it in 1856 and the Norwegian parliament stopped it in 1923, leaving several million people holding the last name it ever gave them.
