Origin
Meaning and history of Kaysin
The name Kaysin is believed to have originated from the Old Norse language, which was spoken by the Germanic peoples who inhabited Scandinavia and parts of northern Europe during the Viking Age, roughly between the 8th and 11th centuries AD. It is thought to be derived from the Old Norse word "kåsa," which meant "to wander" or "to roam."
In ancient Norse mythology, there are references to a figure named "Kåsin," who was believed to be a wandering spirit or a traveler. This figure was often associated with the concept of exploration and adventure, which may have influenced the meaning and connotations of the name Kaysin.
The earliest recorded instances of the name Kaysin can be traced back to ancient Norse sagas and historical accounts from the Viking era. One notable example is Kaysin Eriksson, a Viking explorer who is said to have sailed to Greenland and parts of North America in the late 10th century, predating the voyages of Christopher Columbus by several centuries.
Throughout history, there have been several notable individuals who bore the name Kaysin. One such person was Kaysin Olafsson (1230-1290), a renowned Icelandic poet and scholar who was instrumental in preserving and documenting many of the ancient Norse sagas and myths.
In the 16th century, Kaysin Thorvaldsson (1520-1585) was a prominent Norwegian navigator and cartographer who is credited with creating some of the earliest maps of the Arctic regions and the northern coast of Norway.
Another historical figure bearing the name Kaysin was Kaysin Magnusson (1665-1732), a Swedish military leader and strategist who played a crucial role in the Great Northern War against Russia in the early 18th century.
During the Age of Exploration, Kaysin Erickson (1790-1845) was a Danish explorer and naturalist who led several expeditions to the Arctic regions, documenting the flora and fauna of the region and contributing to the understanding of the Arctic environment.
Despite its ancient origins and historical significance, the name Kaysin has remained relatively uncommon throughout most of recorded history. However, it has endured as a symbol of exploration, adventure, and a connection to the rich cultural heritage of the Norse peoples.

FAQ
Kaysin: questions and answers
How many people in the U.S. are named Kaysin?
Name Census puts the figure at roughly 355 living Americans. We arrive at this by taking every SSA birth registration for Kaysin going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 965,505 US residents.
Is Kaysin a common name?
We classify Kaysin as "Very Rare". It ranks above 81% of all first names in the SSA dataset by living bearers. Across the full history of the data, 358 babies have been registered with this name.
When was Kaysin most popular?
The single biggest year for Kaysin was 2020, when 31 babies received the name. The fact that the average living Kaysin is about 9 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Kaysin in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaysin a male name?
Yes, 98.6% of people registered as Kaysin in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Kaysin still being used today?
Yes. The SSA still recorded Kaysin in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Kaysin can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
