Origin
Meaning and history of Caysey
The given name Caysey is believed to have its origins in the English language, originating as a variant spelling of the more common name Casey. The name itself is derived from an Irish surname, which is an Anglicized form of the Gaelic name "O'Cathasaigh," meaning "descendant of Cathasach."
Cathasach was a personal name derived from the Old Irish word "cath," meaning "battle," and the suffix "-sach," indicating an attribute or descriptive quality. Therefore, the name Cathasach can be interpreted as "warlike" or "fighter." This suggests that the name Caysey may have initially been associated with individuals who possessed warrior-like qualities or came from families with a military background.
One of the earliest recorded instances of the name Caysey can be traced back to the early 17th century. In 1619, a man named Caysey Johnson was documented in the parish records of St. Nicholas, Ipswich, England. This provides evidence that the name, or at least its variant spellings, had already gained some popularity in England by that time.
Throughout history, several notable individuals have borne the name Caysey. One such figure was Caysey Jones (1709-1786), a Welsh Anglican priest and writer who served as the Rector of Llangynhafal in Denbighshire, Wales. Another individual of note was Caysey Thomas (1812-1879), an English cricketer who played first-class cricket for several teams, including the Gentlemen of England.
In the 19th century, Caysey Cartwright (1827-1901) was a prominent architect from England who designed several notable buildings, including the Corn Exchange in Devizes, Wiltshire. Another notable figure was Caysey Llewelyn (1846-1923), a Welsh politician and barrister who served as the Member of Parliament for North Pembrokeshire from 1892 to 1895.
A more recent example is Caysey Jones (1919-2004), an American artist and illustrator known for her work in children's literature. She illustrated several popular books, including the "Fairy Tale Parade" series and "The Little Rabbit Who Wanted Red Wings."
While these are just a few examples, they illustrate the historical presence and diversity of individuals who have carried the name Caysey throughout various parts of the world, particularly in regions with English and Welsh influences.

FAQ
Caysey: questions and answers
How many people in the U.S. are named Caysey?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Caysey 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 Caysey a common name?
We classify Caysey 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 Caysey most popular?
The single biggest year for Caysey was 2000, when 5 babies received the name. The fact that the average living Caysey is about 26 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 Caysey in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Caysey a male name?
Yes, 100.0% of people registered as Caysey 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 Caysey still being used today?
Yes. The SSA still recorded Caysey 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 Caysey 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.
