Origin
Meaning and history of Fiadh
The name Fiadh originates from the Irish Gaelic language and has its roots in ancient Celtic culture. It is derived from the Old Irish word "fiad," which means "wild" or "deer." This connection to nature and the symbolism of the deer as a swift and graceful creature has imbued the name with a sense of freedom and beauty.
Fiadh was a name commonly used in medieval Ireland, particularly among the Irish nobility and aristocracy. It is believed to have been popular during the 8th to 12th centuries, a period when the Irish monasteries were renowned centers of learning and scholarship. Some of the earliest recorded instances of the name can be found in ancient Irish manuscripts and genealogical records from this time.
One of the most notable historical figures bearing the name Fiadh was Fiadh mac Máel Ruanaidh, a 9th-century King of Ailech in Ulster, Ireland. He ruled from 855 to 879 and was renowned for his military prowess and leadership in defending his kingdom against Viking raids.
Another prominent figure was Fiadh na Naomh, an Irish saint and abbess who lived in the 7th century. She founded the monastery of Kildare, which became an important center of learning and spirituality during her lifetime.
In the realm of Irish mythology, Fiadh appears as the name of a beautiful and elusive maiden who was the subject of numerous tales and legends. She was often depicted as a symbol of nature's beauty and the untamed wilderness.
During the Middle Ages, the name Fiadh was also borne by several Irish poets and bards, reflecting the cultural significance of the name in literary circles. One such poet was Fiadh mac Conchobair, who lived in the 12th century and was renowned for his poetic descriptions of nature and the natural world.
Throughout the centuries, the name Fiadh has maintained its distinctive Irish heritage and connection to the ancient Celtic culture. While it may not have been as widely used in more recent times, it has experienced a resurgence in popularity in recent decades as parents seek to revive traditional Irish names with rich historical and cultural significance.

FAQ
Fiadh: questions and answers
How many people in the U.S. are named Fiadh?
Name Census puts the figure at roughly 319 living Americans. We arrive at this by taking every SSA birth registration for Fiadh 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 1,074,465 US residents.
Is Fiadh a common name?
We classify Fiadh as "Very Rare". It ranks above 79.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 321 babies have been registered with this name.
When was Fiadh most popular?
The single biggest year for Fiadh was 2024, when 71 babies received the name. The fact that the average living Fiadh is about 4 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 Fiadh in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Fiadh a female name?
Yes, 100.0% of people registered as Fiadh 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 Fiadh still being used today?
Yes. The SSA still recorded Fiadh 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 Fiadh 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.
