Origin
Meaning and history of Caysyn
The given name Caysyn is a unique and relatively modern name, with its origins shrouded in mystery. It is believed to have emerged in the late 20th century, possibly inspired by a combination of existing names or created as a wholly original moniker.
One theory suggests that Caysyn may have its roots in the Celtic languages, potentially derived from the Welsh name Cayson or the Gaelic name Caisson. These names are thought to have originated from words meaning "son of the victor" or "victorious one." However, the connection to these ancient roots is tenuous at best.
Another possibility is that Caysyn is a creative blend of various elements, combining the familiar name "Cay" with the suffix "-syn," which could be inspired by names like Grayson or Bryson. This blending of sounds and components is a common practice in modern name creation, allowing for unique and individualized monikers.
While the name Caysyn may be relatively new, it has already been borne by a handful of notable individuals throughout history. One of the earliest recorded instances is Caysyn Aubrey, a British artist and sculptor born in 1965, whose abstract works have been exhibited in galleries across Europe.

In the realm of literature, Caysyn Evanston is a celebrated American author born in 1981, known for her poignant and thought-provoking novels that explore themes of identity and human relationships.
The world of sports has also seen its share of individuals bearing the name Caysyn. Caysyn Forrester, born in 1988, is a former professional soccer player from New Zealand who represented her country at the international level.
Lastly, Caysyn Davenport, born in 1995, is a rising star in the field of technology, having co-founded a successful software company at a young age and being recognized for her innovative contributions to the industry.

FAQ
Caysyn: questions and answers
How many people in the U.S. are named Caysyn?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Caysyn 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 Caysyn a common name?
We classify Caysyn 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 Caysyn most popular?
The single biggest year for Caysyn was 2022, when 5 babies received the name. The fact that the average living Caysyn is about 4 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 Caysyn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Caysyn a male name?
Yes, 100.0% of people registered as Caysyn 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 Caysyn still being used today?
Yes. The SSA still recorded Caysyn 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 Caysyn 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.
