Origin
Meaning and history of Kyliann
The name Kyliann is a relatively modern variation of the more traditional name Kylian, which has its roots in the Celtic language. The name Kylian is derived from the Old Breton word "kilian," which means "slender" or "slight." This suggests that the name Kyliann may have originally been associated with someone of a slim or delicate build.
Although the name Kyliann is a more recent iteration, the name Kylian has a long history dating back to the Middle Ages. One of the earliest recorded instances of the name can be found in the Welsh Triads, a collection of traditional stories and legends from ancient Wales. In these texts, Kylian is mentioned as the name of a legendary figure, though details about his life and deeds are scarce.
In the 6th century, there was a notable figure named Kylian who played a significant role in the spread of Christianity in what is now modern-day Germany. Saint Kylian, along with his companions Colman and Totnan, traveled from Ireland to establish monasteries and preach the Christian faith in the region of Franconia. His efforts earned him recognition as a saint, and he is celebrated as the patron saint of Würzburg, where he was eventually martyred.
Throughout the Middle Ages and the Renaissance period, the name Kylian remained relatively uncommon, though it was occasionally bestowed upon individuals of noble or religious standing. One notable example is Kylian van Rensselaer, a Dutch merchant and landowner who was born in 1592 and is remembered for his role in the early colonization of New Netherland (present-day New York).
In more recent times, the name Kylian has gained greater popularity, particularly in its variant spellings like Kyliann. One of the most famous bearers of this name is Kylian Mbappé, the French professional footballer who was born in 1998 and has already achieved widespread acclaim for his impressive skills on the pitch.
Another notable Kylian is Kylian Hazard, a Belgian professional footballer born in 1995, who is the younger brother of the renowned player Eden Hazard. In the realm of music, Kylian Truilhé is a French singer and songwriter born in 1984, known for his distinctive pop-rock sound.
While the name Kyliann is a relatively modern variation, it carries with it a rich history and cultural significance rooted in the Celtic traditions of ancient Britain and France. Its enduring popularity over the centuries is a testament to the enduring appeal of this name and its various forms.

FAQ
Kyliann: questions and answers
How many people in the U.S. are named Kyliann?
Name Census puts the figure at roughly 15 living Americans. We arrive at this by taking every SSA birth registration for Kyliann 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 22,850,289 US residents.
Is Kyliann a common name?
We classify Kyliann as "Very Rare". It ranks above 35.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 15 babies have been registered with this name.
When was Kyliann most popular?
The single biggest year for Kyliann was 2009, when 5 babies received the name. The fact that the average living Kyliann is about 11 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 Kyliann in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kyliann a female name?
Yes, 66.7% of people registered as Kyliann in the SSA data are female. 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 Kyliann still being used today?
Yes. The SSA still recorded Kyliann 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 Kyliann 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.
