Origin
Meaning and history of Blaidyn
The given name Blaidyn has its origins in the Welsh language and culture. It is derived from the Welsh word "blaidd," which means "wolf." The name first emerged during the early medieval period in Wales, likely as a reference to the wolf's strength and prowess as a fierce hunter and protector.
In ancient Welsh mythology, the wolf was a revered and symbolic creature, often associated with courage, loyalty, and the guardianship of the natural world. The name Blaidyn may have been bestowed upon individuals who embodied these qualities or were believed to possess a wolf-like spirit.
One of the earliest recorded instances of the name Blaidyn can be found in the Llyfr Aneirin, a 13th-century manuscript containing the poems of the 6th-century bard Aneirin. The name appears in a poem dedicated to the warrior Blaidyn ap Cynfelyn, who fought alongside Aneirin in the Battle of Catraeth (Catterick) against the Anglo-Saxons in the late 6th century.
Throughout the centuries, several notable figures have borne the name Blaidyn. One such individual was Blaidyn ap Dyfnwal (c. 1120-1190), a Welsh prince and Lord of Senghenydd who played a significant role in the struggles against the Norman conquest of Wales in the 12th century.
Another historical figure named Blaidyn was Blaidyn Ddu (c. 1250-1310), a Welsh warrior and landowner who fought alongside Llywelyn ap Gruffudd, the last sovereign prince of Wales, during the Welsh Wars of Independence against King Edward I of England.
In the 15th century, Blaidyn ap Rhys (c. 1420-1490) was a prominent Welsh bard and poet who composed works in praise of the House of Tudor and the Welsh gentry of his time.
Additionally, Blaidyn Fychan (c. 1550-1620) was a renowned Welsh harpist and composer who contributed to the preservation and promotion of traditional Welsh music and culture during the Renaissance period.
Lastly, Blaidyn Tew (c. 1670-1740) was a Welsh landowner and patron of the arts, known for his support of local poets and musicians in the region of Glamorgan during the 18th century.

FAQ
Blaidyn: questions and answers
How many people in the U.S. are named Blaidyn?
Name Census puts the figure at roughly 6 living Americans. We arrive at this by taking every SSA birth registration for Blaidyn 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 57,125,723 US residents.
Is Blaidyn a common name?
We classify Blaidyn as "Very Rare". It ranks above 22.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 6 babies have been registered with this name.
When was Blaidyn most popular?
The single biggest year for Blaidyn was 2013, when 6 babies received the name. The fact that the average living Blaidyn is about 13 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 Blaidyn in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Blaidyn a male name?
Yes, 100.0% of people registered as Blaidyn 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 Blaidyn still being used today?
Yes. The SSA still recorded Blaidyn 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 Blaidyn 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.
