Origin

Meaning and history of Kros

The name Kros is a relatively uncommon given name with roots that can be traced back to ancient Greece. It is believed to have originated from the Greek word "kros," which means "the edge of a blade" or "the cutting edge." This suggests that the name may have been associated with warriors, soldiers, or those skilled in combat.

In ancient Greek mythology, there is a reference to a minor deity named Kros, who was said to be the personification of the cutting edge of a blade. However, there is limited information available about this figure, and it is uncertain whether the name Kros gained popularity due to this mythological connection.

The earliest recorded instances of the name Kros can be found in ancient Greek inscriptions and historical records dating back to the 5th century BCE. One notable individual was Kros of Argos, a Greek philosopher and writer who lived around 450 BCE. He is known for his work on ethics and virtue, although very little of his writings have survived to the present day.

During the Byzantine Empire, which lasted from the 4th to the 15th century CE, the name Kros appeared occasionally among the nobility and upper classes. One prominent bearer of the name was Kros Palaiologos, a high-ranking military commander who served under Emperor Manuel II Palaiologos in the early 15th century.

In the realm of literature, there is a character named Kros in the epic poem "The Argonautica" by Apollonius of Rhodes, written in the 3rd century BCE. This Kros was a skilled archer who accompanied Jason and the Argonauts on their quest for the Golden Fleece.

Another notable figure was Kros of Syracuse, a Greek physician and philosopher who lived in the 3rd century BCE. He is credited with making significant contributions to the field of medicine, particularly in the areas of anatomy and physiology.

During the Renaissance period, the name Kros experienced a brief resurgence, although it remained relatively uncommon. One individual of note was Kros Venetian, an Italian artist and sculptor who was active in the 15th century. He is known for his intricate woodcarvings and religious sculptures that adorned several churches in Venice.

While the name Kros has never been widely popular, it has maintained a niche presence throughout history, primarily in regions with strong Greek cultural influences or connections to the Byzantine Empire. Its unique etymology and associations with ancient Greek mythology and literature have contributed to its enduring appeal among those seeking a name with a rich historical background.

FAQ

Kros: questions and answers

How many people in the U.S. are named Kros?

Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Kros 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 68,550,868 US residents.

Is Kros a common name?

We classify Kros as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.

When was Kros most popular?

The single biggest year for Kros was 2002, when 5 babies received the name. The fact that the average living Kros is about 24 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 Kros in that year. That makes it useful for spotting when the name rose, peaked, or faded.

Is Kros a male name?

Yes, 100.0% of people registered as Kros 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 Kros still being used today?

Yes. The SSA still recorded Kros 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 Kros 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.
