Origin
Meaning and history of Kassian
The name Kassian originated from the Greek name Kassianos, which derived from the Latin name Cassianus. The name Cassianus itself was a Roman family name that may have originated from the ancient city of Cassinum or Casinum, located in Campania, Italy. The name is also believed to have roots in the Latin word "cassis," meaning "helmet."
Kassian was a relatively common name in the Byzantine Empire and the Eastern Orthodox Church, particularly among monks and religious figures. One of the earliest recorded individuals with the name was Kassian, also known as John Cassian (c. 360-435 AD), a renowned monk, theologian, and one of the founders of Western monasticism. He was born in Scythia Minor (modern-day Romania) and played a significant role in introducing Eastern monastic traditions to the West.
Another notable historical figure was Kassian Bek (c. 1420-1480), a Russian icon painter and one of the most prominent masters of the Muscovite school of iconography. His works were highly influential and helped shape the artistic traditions of the Russian Orthodox Church.
In the 16th century, Kassian Kozhukhov (c. 1520-1600) was a skilled Russian jeweler and goldsmith who worked for the royal court of Ivan the Terrible. His intricate creations, including precious metalwork and jewelry, are now considered masterpieces of Russian decorative art.
Moving to the 18th century, Kassian Mikhailovich Golovin (1700-1775) was a Russian diplomat and statesman who served as the Russian ambassador to the Ottoman Empire and later as the Governor of Moscow. He played a crucial role in shaping Russia's foreign policy during the reign of Empress Elizabeth Petrovna.
In the realm of literature, Kassian Kiselev (1834-1889) was a Russian writer and playwright who gained recognition for his satirical works and comedies that portrayed contemporary Russian society.
While the name Kassian has its roots in ancient Greek and Latin, it has been used across various cultures and regions, particularly in Eastern Europe and the Slavic regions, where it has maintained a strong presence throughout history.

FAQ
Kassian: questions and answers
How many people in the U.S. are named Kassian?
Name Census puts the figure at roughly 221 living Americans. We arrive at this by taking every SSA birth registration for Kassian 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 1,550,925 US residents.
Is Kassian a common name?
We classify Kassian as "Very Rare". It ranks above 75.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 222 babies have been registered with this name.
When was Kassian most popular?
The single biggest year for Kassian was 2023, when 49 babies received the name. The fact that the average living Kassian is about 5 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 Kassian in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kassian a male name?
Yes, 100.0% of people registered as Kassian 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 Kassian still being used today?
Yes. The SSA still recorded Kassian 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 Kassian 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.
