Origin
Meaning and history of Kassaius
The name Kassaius appears to have its origins in ancient Greek culture, likely derived from the word "kassios" which referred to a type of laurel plant. This would suggest the name dates back to classical antiquity, perhaps as early as the 5th century BCE.
In ancient Greek mythology, the laurel plant held great symbolic importance and was associated with figures like Apollo, the god of poetry and music. It's possible Kassaius was originally a name bestowed upon those with artistic talents or connections to the cult of Apollo.
Early recorded examples of the name are scarce, but it seems to have been used sporadically throughout the Byzantine and Medieval periods in parts of Greece and Anatolia. One noteworthy bearer was Kassaius of Ephesus (c. 120-180 CE), a Greek philosopher and orator who wrote treatises on rhetoric and logic.
During the Renaissance, the name experienced a mild resurgence, likely due to the rediscovery and renewed interest in classical Greek culture. Kassaius Trelawney (1492-1572) was an English scholar and translator who produced some of the first English versions of ancient Greek texts.
In the 18th century, Kassaius Marcellus (1737-1798) was a French botanist and naturalist who cataloged numerous plant species from around the world. His seminal work "Genera Plantarum" influenced the development of modern taxonomic systems.
More recently, Kassaius Theophanous (1909-1997) was a Cypriot politician and barrister who played a key role in the Cypriot independence movement and later served as President of Cyprus in the 1970s.
Despite its ancient pedigree, the name Kassaius has remained quite rare and obscure in most parts of the world. But its connection to laurels, poetry, philosophy, and nature lends it an air of intellectual and artistic distinction.

FAQ
Kassaius: questions and answers
How many people in the U.S. are named Kassaius?
Name Census puts the figure at roughly 11 living Americans. We arrive at this by taking every SSA birth registration for Kassaius 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 31,159,485 US residents.
Is Kassaius a common name?
We classify Kassaius as "Very Rare". It ranks above 30.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 11 babies have been registered with this name.
When was Kassaius most popular?
The single biggest year for Kassaius was 2023, when 11 babies received the name. The fact that the average living Kassaius is about 3 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 Kassaius in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kassaius a male name?
Yes, 100.0% of people registered as Kassaius 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 Kassaius still being used today?
Yes. The SSA still recorded Kassaius 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 Kassaius 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.
