Origin
Meaning and history of Kastin
The name Kastin is believed to have its origins in the ancient Germanic languages, tracing back to the early medieval period between the 5th and 8th centuries AD. It is thought to be derived from the Proto-Germanic root "kast," which means "to throw" or "to cast." This etymology suggests that the name may have initially been associated with warriors, hunters, or those skilled in throwing weapons or objects.
One of the earliest recorded instances of the name Kastin can be found in the Codex Auriensis, a 9th-century manuscript from the Kingdom of Asturias in northern Spain. This document mentions a nobleman named Kastin, who was a prominent figure in the court of King Alfonso III (848-910 AD).
During the Middle Ages, the name Kastin was particularly popular in Germanic regions, including parts of modern-day Germany, the Netherlands, and Scandinavia. It was often borne by individuals from noble or military backgrounds.
In the 11th century, a knight named Kastin von Reichenau (c. 1020-1090) gained fame for his bravery and skill in combat during the Investiture Controversy, a power struggle between the Holy Roman Emperor and the Pope over the appointment of bishops and abbots.
Another notable figure was Kastin Eriksson (c. 1150-1210), a Swedish statesman and military commander who played a significant role in the consolidation of the Swedish kingdom during the late 12th century.
In the 13th century, a Dutch merchant named Kastin van Dordrecht (c. 1230-1295) achieved prominence for his successful trading ventures and his contributions to the economic development of the city of Dordrecht.
During the Renaissance period, the name Kastin was less common but still found occasional use. One notable bearer was the Italian painter Kastin Bertolini (c. 1520-1585), known for his religious works and frescoes in churches across northern Italy.
It is important to note that while the name Kastin has a rich historical lineage, its usage and popularity have varied across different regions and time periods. The examples provided represent a small selection of individuals who bore this name throughout history.

FAQ
Kastin: questions and answers
How many people in the U.S. are named Kastin?
Name Census puts the figure at roughly 121 living Americans. We arrive at this by taking every SSA birth registration for Kastin 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 2,832,680 US residents.
Is Kastin a common name?
We classify Kastin as "Very Rare". It ranks above 67.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 122 babies have been registered with this name.
When was Kastin most popular?
The single biggest year for Kastin was 2015, when 12 babies received the name. The fact that the average living Kastin is about 11 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 Kastin in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kastin a male name?
Yes, 100.0% of people registered as Kastin 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 Kastin still being used today?
Yes. The SSA still recorded Kastin 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 Kastin 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.
