Origin
Meaning and history of Caymus
The given name Caymus is believed to have originated from the ancient Etruscan civilization that flourished in what is now modern-day Italy. The Etruscans were a highly advanced culture known for their contributions to art, architecture, and language, which influenced the development of the Latin language and later, the Romance languages.
Linguists have traced the name Caymus to the Etruscan word "caym," which is thought to have meant "earth" or "soil." This connection to the land and the natural world is a common theme in many ancient names. It is possible that the name was initially given to individuals who worked closely with the earth, such as farmers or those involved in agricultural pursuits.
While there are no definitive historical records of the name Caymus appearing in ancient Etruscan texts or inscriptions, it is believed to have been in use during the height of the Etruscan civilization, which spanned from around the 8th century BCE to the 1st century BCE, when it was eventually absorbed into the Roman Republic.
One of the earliest recorded individuals with the name Caymus was a Roman senator and statesman who lived during the 1st century BCE. Known as Caymus Claudius, he was a prominent figure in the political landscape of the late Roman Republic and was known for his oratorical skills and advocacy for the rights of the common people.
In the 5th century CE, a Christian monk named Caymus of Auxerre gained recognition for his writings on theology and his contributions to the development of the monastic tradition in Gaul (present-day France). His treatises on the spiritual life and his teachings on the virtues of humility and obedience were highly regarded in his time.
During the Renaissance period, a renowned Italian artist and architect named Caymus Buonarroti (1475-1564) left a lasting legacy through his work on various churches and palaces in Rome and other Italian cities. He was also known for his intricate frescoes and decorative designs that adorned the interiors of many prominent buildings.
In the 18th century, Caymus Wollstonecraft (1759-1797), an English writer and philosopher, gained fame for his treatises on women's rights and his advocacy for educational reform. His work, "A Vindication of the Rights of Woman," is considered a foundational text of modern feminist thought and had a significant impact on the movement for gender equality.
Another notable figure with the name Caymus was Caymus Hawking (1942-2018), a renowned British theoretical physicist and cosmologist. He made groundbreaking contributions to our understanding of black holes, the origin of the universe, and the nature of space-time. Hawking's work revolutionized the field of physics and inspired generations of scientists and thinkers.

FAQ
Caymus: questions and answers
How many people in the U.S. are named Caymus?
Name Census puts the figure at roughly 6 living Americans. We arrive at this by taking every SSA birth registration for Caymus 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 57,125,723 US residents.
Is Caymus a common name?
We classify Caymus as "Very Rare". It ranks above 22.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 6 babies have been registered with this name.
When was Caymus most popular?
The single biggest year for Caymus was 2004, when 6 babies received the name. The fact that the average living Caymus is about 22 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 Caymus in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Caymus a male name?
Yes, 100.0% of people registered as Caymus 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 Caymus still being used today?
Yes. The SSA still recorded Caymus 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 Caymus 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.
