Origin
Meaning and history of Kacelyn
The name Kacelyn is a modern English variation of the ancient Greek name Kassandra. The name Kassandra is derived from the Greek words "kekasmai," meaning "to shine," and "aner," meaning "man." The name can be interpreted as "shining upon men" or "the one who enthralls men."
In Greek mythology, Kassandra was a Trojan princess who was blessed with the gift of prophecy by Apollo. However, when she refused Apollo's romantic advances, he cursed her so that no one would believe her prophecies. Kassandra's tragic story is recounted in various ancient Greek texts, including Homer's Iliad and Aeschylus' play Agamemnon.
The earliest recorded use of the name Kassandra dates back to ancient Greece, where it was a relatively popular name among the nobility and upper classes. Over time, the name spread to other parts of Europe and underwent various spellings and modifications, including Cassandra, Casandra, and eventually, the modern English variation, Kacelyn.
Throughout history, there have been several notable individuals named Kassandra or its variants. One of the earliest was Kassandra of Macedon, a Macedonian princess who lived in the 4th century BC and was the daughter of King Philip II of Macedon and Thessalian princess Nicesipolis.
In the 16th century, Italian Renaissance painter Sofonisba Anguissola, born in 1532, was known for her portraits and self-portraits. She was one of the first women to gain recognition as a professional painter in the Renaissance period.
Cassandra Austen, born in 1773, was the sister of the famous English novelist Jane Austen. She was known for her close relationship with her sister and for preserving many of Jane Austen's letters and manuscripts.
In the 19th century, Kassandra Federovna Romanova, born in 1775, was a Russian Grand Duchess and the daughter of Tsar Paul I of Russia. She was known for her philanthropic work and her patronage of the arts.
More recently, Cassandra Wilson, born in 1955, is an American jazz singer, songwriter, and producer who has won several Grammy Awards and is recognized for her unique blend of jazz, blues, and folk music.

FAQ
Kacelyn: questions and answers
How many people in the U.S. are named Kacelyn?
Name Census puts the figure at roughly 212 living Americans. We arrive at this by taking every SSA birth registration for Kacelyn 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 1,616,766 US residents.
Is Kacelyn a common name?
We classify Kacelyn as "Very Rare". It ranks above 75% of all first names in the SSA dataset by living bearers. Across the full history of the data, 214 babies have been registered with this name.
When was Kacelyn most popular?
The single biggest year for Kacelyn was 2014, when 16 babies received the name. The fact that the average living Kacelyn is about 10 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 Kacelyn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kacelyn a female name?
Yes, 100.0% of people registered as Kacelyn 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 Kacelyn still being used today?
Yes. The SSA still recorded Kacelyn 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 Kacelyn 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.
