Origin
Meaning and history of Kayleon
The name Kayleon has its roots in the ancient Celtic culture, originating from the regions of modern-day Ireland and Scotland. It is believed to have been derived from the old Celtic words "caill" meaning forest or wood, and "leon" meaning lion. The name essentially translates to "lion of the forest" or "woodland lion."
In the early medieval period, the name was rarely documented, but it is said to have been used by a few Celtic chieftains and warriors. One of the earliest recorded instances of the name can be found in the 8th century Irish annals, where a Kayleon mac Fergus is mentioned as a minor clan leader in the kingdom of Connaught.
As the centuries passed, the name gained some popularity among the nobility and ruling classes of the Celtic regions. A notable figure in history who bore this name was Kayleon of Argyll, a 12th century Scottish nobleman and military commander who played a significant role in the Wars of Scottish Independence against the English.
In the 15th century, a Welsh scholar and poet named Kayleon ap Rhys gained recognition for his works on Celtic mythology and folklore. He is believed to have been born around 1420 and lived until the late 1490s.
Another historical figure of note was Kayleon O'Donnell, an Irish chieftain from the 16th century who led his clan in battles against the English forces during the Nine Years' War in Ireland. He was born in 1561 and died in 1629.
In the realm of religion, the name Kayleon was also associated with a few notable figures. One such individual was Kayleon of Iona, a 7th century Scottish monk and scholar who contributed to the spread of Christianity in the Scottish Isles and northern Britain.
While the name Kayleon has its roots in the Celtic cultures, it has remained relatively obscure throughout history, with only a handful of notable individuals bearing this moniker. Nevertheless, the unique and evocative meaning of "lion of the forest" has endured, offering a glimpse into the rich cultural heritage of the ancient Celts.

FAQ
Kayleon: questions and answers
How many people in the U.S. are named Kayleon?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Kayleon 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 Kayleon a common name?
We classify Kayleon 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 Kayleon most popular?
The single biggest year for Kayleon was 2021, when 5 babies received the name. The fact that the average living Kayleon 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 Kayleon in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kayleon a male name?
Yes, 100.0% of people registered as Kayleon 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 Kayleon still being used today?
Yes. The SSA still recorded Kayleon 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 Kayleon 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.
