Origin
Meaning and history of Jefrin
The name Jefrin is believed to have originated from the ancient Gaelic language spoken in parts of Ireland and Scotland. It is thought to be derived from the old Gaelic word "ieffryn," which translates to "peaceful river." This suggests that the name may have been initially given to those born near the banks of a serene river or stream.
In the early medieval period, around the 5th to 6th centuries, the name Jefrin was primarily found in Irish and Scottish communities. It was a popular name among the Celts, who revered nature and the elements. The name's association with a peaceful river likely held spiritual significance for these ancient cultures.
One of the earliest recorded instances of the name Jefrin can be found in the Annals of Inisfallen, a chronicle of medieval Irish history dating back to the 11th century. The text mentions a Jefrin mac Áedáin, a notable figure from the Kingdom of Dál Riata, which spanned parts of modern-day Scotland and Northern Ireland.
Throughout history, several notable individuals have borne the name Jefrin. One such figure was Jefrin of Kells, an Irish monk and scribe who lived in the 9th century. He is renowned for his contributions to the intricate illuminated manuscripts of the time, particularly the Book of Kells, which is considered a masterpiece of Western calligraphy and illustration.
Another prominent bearer of the name was Jefrin the Red, a Scottish warrior and chieftain who lived in the 12th century. He played a crucial role in the resistance against the Norman invaders, leading his clan in several battles to protect their lands and way of life.
In the 14th century, Jefrin de Brus was a Scottish nobleman and military commander who fought alongside Robert the Bruce during the Wars of Scottish Independence. His bravery and loyalty to the Scottish cause earned him a place in the historical accounts of the time.
Jefrin Fitzgerald, an Irish poet and playwright from the 16th century, is also noteworthy. His works, which often celebrated the natural beauty of Ireland and its rich cultural heritage, have been preserved and studied by scholars over the centuries.
Lastly, Jefrin MacCulloch was a renowned Scottish architect and stonemason who lived in the 17th century. He is credited with designing and constructing several iconic buildings and structures, including the Dunvegan Castle on the Isle of Skye, which stands as a testament to his architectural prowess.

FAQ
Jefrin: questions and answers
How many people in the U.S. are named Jefrin?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Jefrin 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 Jefrin a common name?
We classify Jefrin 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 Jefrin most popular?
The single biggest year for Jefrin was 2008, when 5 babies received the name. The fact that the average living Jefrin is about 18 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 Jefrin in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jefrin a male name?
Yes, 100.0% of people registered as Jefrin 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 Jefrin still being used today?
Yes. The SSA still recorded Jefrin 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 Jefrin 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.
