Origin
Meaning and history of Trejaun
The name Trejaun has its roots in the ancient Celtic language of Brittonic, which was spoken in parts of what is now modern-day France and Great Britain. It is derived from the Proto-Celtic word "trēgā," meaning "homestead" or "settlement," and the suffix "-un," which was commonly used in personal names to denote a sense of belonging or association.
One of the earliest known references to the name Trejaun can be found in the 8th century manuscript "De Situ Britanniae," written by the Welsh monk Nennius. This text mentions a Brittonic chieftain named Trejaun who led his tribe in battles against the encroaching Anglo-Saxon invaders.
During the Middle Ages, the name gained popularity among the Welsh and Cornish nobility. In the 12th century, a Cornish knight named Trejaun de Tintagel was recorded as having fought alongside King Richard I during the Third Crusade. His bravery and valor were celebrated in several contemporary chronicles and ballads.
In the 15th century, a Welsh poet and bard named Trejaun ap Gwilym gained recognition for his intricate and emotionally charged love poems. His work was widely celebrated and helped to preserve the Welsh literary tradition during a time of English cultural dominance.
Fast forward to the 17th century, and we find Trejaun O'Flaherty, an Irish chieftain who played a significant role in the Confederate Wars of the 1640s. He was known for his fierce resistance against the Cromwellian forces and his unwavering defense of Catholic landowners in Ireland.
Another notable bearer of the name was Trejaun Montague, a French explorer and naturalist who accompanied the famous expedition of Lewis and Clark across the American West in the early 19th century. His detailed journals and illustrations of the flora and fauna encountered on the journey were invaluable contributions to the understanding of the region's natural history.

FAQ
Trejaun: questions and answers
How many people in the U.S. are named Trejaun?
Name Census puts the figure at roughly 12 living Americans. We arrive at this by taking every SSA birth registration for Trejaun 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 28,562,862 US residents.
Is Trejaun a common name?
We classify Trejaun as "Very Rare". It ranks above 32.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 12 babies have been registered with this name.
When was Trejaun most popular?
The single biggest year for Trejaun was 1999, when 7 babies received the name. The fact that the average living Trejaun is about 24 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 Trejaun in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Trejaun a male name?
Yes, 100.0% of people registered as Trejaun 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 Trejaun still being used today?
Yes. The SSA still recorded Trejaun 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 Trejaun 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.
