Origin
Meaning and history of Caylib
The given name Caylib has its origins in the ancient Celtic culture of the British Isles, dating back to the early medieval period around the 5th to 9th centuries AD. It is believed to have derived from the Old Welsh or Brythonic Celtic words "cai" meaning "enclosure" or "battlefield" and "lib" meaning "prince" or "leader". Thus, the name Caylib may have originally referred to a prince or leader who was associated with a fortified enclosure or a battlefield.
One of the earliest recorded mentions of the name Caylib can be found in the ancient Welsh chronicles known as the "Annales Cambriae", which document events and individuals from the 5th to 10th centuries in Wales and the surrounding regions. The name appears in these chronicles, albeit with slightly different spellings such as "Caileb" or "Cailiub".
In the 7th century, a notable figure named Caylib ap Gwyddno is mentioned in the Welsh Triads, a collection of traditional stories and historical accounts. Caylib ap Gwyddno was a prince and warrior who is said to have fought against the invading Saxons in the region of Gwynedd, present-day northwest Wales.
Another historical figure bearing the name Caylib was Caylib ap Rhodri, a 9th-century Welsh prince who ruled over the kingdom of Gwynedd. He is mentioned in the "Annales Cambriae" and other medieval Welsh sources as a significant ruler during a tumultuous period of conflict between the Welsh kingdoms and the expanding Anglo-Saxon kingdoms.
In the 11th century, a monk and scholar named Caylib of Monmouth lived in the Welsh town of Monmouth. He is known for his writings on Welsh history and folklore, including the work "Historia Regum Britanniae" (History of the Kings of Britain), which contains accounts of legendary figures like King Arthur.
Another notable figure named Caylib was Caylib MacAlpin, a 9th-century Scottish king who is credited with uniting the Picts and Scots into the Kingdom of Alba, the precursor to the modern nation of Scotland. He ruled from 843 to 858 AD and is recognized as the founder of the Scottish monarchy.
While the name Caylib has its roots in the Celtic cultures of the British Isles, it has been adopted and used in various forms across different regions and time periods throughout history. However, the specific origins and meanings associated with the name remain closely tied to its ancient Celtic heritage and the historical figures who bore this name in the early medieval era.

FAQ
Caylib: questions and answers
How many people in the U.S. are named Caylib?
Name Census puts the figure at roughly 7 living Americans. We arrive at this by taking every SSA birth registration for Caylib 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 48,964,905 US residents.
Is Caylib a common name?
We classify Caylib as "Very Rare". It ranks above 23.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 7 babies have been registered with this name.
When was Caylib most popular?
The single biggest year for Caylib was 2009, when 7 babies received the name. The fact that the average living Caylib is about 17 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 Caylib in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Caylib a male name?
Yes, 100.0% of people registered as Caylib 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 Caylib still being used today?
Yes. The SSA still recorded Caylib 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 Caylib 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.
