Origin
Meaning and history of Breidyn
The given name Breidyn is believed to have its origins in the ancient Celtic language of Brittonic, which was spoken in parts of what is now Great Britain and France during the Iron Age and Roman periods. Linguists suggest that the name is derived from the Proto-Celtic root *brig-, meaning "high" or "exalted," combined with the diminutive suffix -yn, indicating affection or endearment.
This name may have been initially used by the Britons, an ancient Celtic people who inhabited the island of Great Britain before the Anglo-Saxon invasion. Its earliest recorded use is uncertain, but it likely predates written records due to the oral tradition of naming practices among the ancient Celts.
There are no known historical references to the name Breidyn in ancient texts or religious scriptures, as it was likely a personal name used among the common people rather than prominent figures. However, the name's Celtic roots and potential connection to concepts of height or exaltation may have held symbolic significance for those who bore it.
The first recorded instance of the name Breidyn is from the 6th century CE, when it appears in the form "Bridyn" in the Harleian Genealogies, a collection of Welsh genealogical records. This entry suggests that the name was in use among the ancient Britons or their descendants in Wales during the early medieval period.
Throughout history, several notable individuals have borne the name Breidyn:
1. Breidyn ap Rhys (c. 1150-1212), a Welsh prince and Lord of Senghenydd, who played a role in the struggles for power in the Welsh Marches during the late 12th century.
2. Breidyn Vaughan (c. 1390-1460), a Welsh landowner and member of the gentry class, who held estates in Radnorshire and served as a justice of the peace.
3. Breidyn Griffith (c. 1525-1590), a Welsh clergyman and scholar who served as the Dean of St. Asaph's Cathedral and was known for his translations of religious texts into Welsh.
4. Breidyn Jones (1675-1737), a Welsh poet and schoolteacher who composed works in both Welsh and English and was celebrated for his skillful use of the strict meter form known as the cywydd.
5. Breidyn Williams (1825-1901), a Welsh industrialist and entrepreneur who founded the Breidyn Tinplate Works in Wrexham, contributing to the growth of the Welsh tinplate industry in the 19th century.

FAQ
Breidyn: questions and answers
How many people in the U.S. are named Breidyn?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Breidyn going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables.

When was Breidyn most popular?
The single biggest year for Breidyn was 2008, when 5 babies received the name. The fact that the average living Breidyn 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 Breidyn in that year. That makes it useful for spotting when the name rose, peaked, or faded.

Is Breidyn still being used today?
Yes. The SSA still recorded Breidyn 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 Breidyn 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.
