Origin
Meaning and history of Deylin
The given name Deylin has its roots in the ancient Celtic culture, originating from the Brittonic branch of the Celtic languages spoken in parts of present-day Britain and France during the Iron Age and Roman era. It is believed to be derived from the Proto-Celtic word "deilo," meaning "to divide" or "to share," possibly alluding to the concept of fair distribution or equitable treatment.
One of the earliest recorded instances of the name Deylin can be traced back to the 6th century CE, where it appears in the annals of the Kingdom of Powys, a Welsh successor state to the Roman province of Britannia Superior. The name was borne by a minor prince named Deylin ap Rhys, who ruled over a small territory in what is now central Wales.
In the 9th century, a Breton monk and scholar named Deylin de Vannes gained considerable renown for his translations of Latin religious texts into the Breton language, facilitating the spread of Christianity among the Celtic populations of Brittany. His work played a crucial role in preserving the Breton linguistic and cultural heritage during the Middle Ages.
During the High Middle Ages, the name Deylin surfaced in various historical records across the British Isles. Notably, Deylin of Arden, a minor nobleman from Warwickshire, England, was mentioned in the Domesday Book of 1086 as a landholder in the region.
In the late 12th century, a Welsh bard and poet named Deylin Llwyd gained recognition for his poetic works celebrating the exploits of the Princes of Gwynedd. His compositions were widely circulated and contributed to the preservation of Welsh literary traditions.
Fast-forwarding to the 16th century, Deylin Goch, a renowned Welsh longbowman, earned a place in history for his valiant service during the Tudor conquest of Ireland, where he was praised for his exceptional archery skills and bravery on the battlefield.
These are just a few examples of notable individuals who bore the name Deylin throughout history, demonstrating its enduring presence and cultural significance across various Celtic regions and time periods.

FAQ
Deylin: questions and answers
How many people in the U.S. are named Deylin?
Name Census puts the figure at roughly 143 living Americans. We arrive at this by taking every SSA birth registration for Deylin 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 2,396,883 US residents.
Is Deylin a common name?
We classify Deylin as "Very Rare". It ranks above 69.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 144 babies have been registered with this name.
When was Deylin most popular?
The single biggest year for Deylin was 2024, when 16 babies received the name. The fact that the average living Deylin 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 Deylin in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Deylin a female name?
Yes, 70.8% of people registered as Deylin 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 Deylin still being used today?
Yes. The SSA still recorded Deylin 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 Deylin 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.
