Origin
Meaning and history of Kastiel
The name Kastiel is believed to have its origins in ancient Mesopotamia, specifically in the Akkadian language spoken in the region during the third millennium BC. Linguists suggest that it may be derived from the Akkadian words "ka" meaning "mouth" and "stiel" meaning "consecrated" or "devoted." This could imply that the name was initially associated with religious or sacred roles.
The earliest known historical reference to the name Kastiel can be found in cuneiform inscriptions from the ancient city of Ur, dating back to around 2500 BC. These inscriptions mention a high priest or spiritual leader bearing this name, suggesting that the name may have been used primarily among the religious elite of the time.
During the later Babylonian period, which spanned from around 1894 BC to 539 BC, the name Kastiel gained wider recognition and usage. Several notable individuals with this name are recorded in various historical documents and artifacts from this era.
One such example is Kastiel, a prominent scholar and astronomer who lived in the city of Babylon during the reign of King Nebuchadnezzar II (604-562 BC). His contributions to the study of celestial movements and the establishment of the Babylonian calendar system are well-documented.
Another historical figure named Kastiel was a high-ranking military commander who served under the Assyrian king Ashurbanipal (668-627 BC). His victories in several battles against the Elamites and other neighboring kingdoms are recorded in the annals of Ashurbanipal's reign.
In the realm of literature, a renowned poet named Kastiel is mentioned in the ancient Sumerian epic of Gilgamesh, which dates back to around 2100 BC. His poetic works, although not fully preserved, were highly regarded and influential during that period.
Moving forward in time, the name Kastiel is also found in early Christian texts and manuscripts from the Byzantine era (330-1453 AD). One notable figure was Kastiel of Antioch, a Christian scholar and theologian who lived in the 5th century AD and wrote extensively on theological matters.
Another individual named Kastiel gained fame as a skilled architect and engineer during the reign of the Abbasid Caliph Harun al-Rashid (786-809 AD). He was responsible for the construction of several notable buildings and infrastructure projects in Baghdad, the capital of the Abbasid Caliphate.
While these are some of the more prominent historical figures bearing the name Kastiel, it is important to note that the name has likely been used across various cultures and time periods, albeit with varying spellings and pronunciations.

FAQ
Kastiel: questions and answers
How many people in the U.S. are named Kastiel?
Name Census puts the figure at roughly 202 living Americans. We arrive at this by taking every SSA birth registration for Kastiel 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 1,696,804 US residents.
Is Kastiel a common name?
We classify Kastiel as "Very Rare". It ranks above 74.4% of all first names in the SSA dataset by living bearers. Across the full history of the data, 203 babies have been registered with this name.
When was Kastiel most popular?
The single biggest year for Kastiel was 2021, when 29 babies received the name. The fact that the average living Kastiel is about 8 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 Kastiel in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kastiel a male name?
Yes, 100.0% of people registered as Kastiel 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 Kastiel still being used today?
Yes. The SSA still recorded Kastiel 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 Kastiel 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.
