Origin
Meaning and history of Mileigh
The name Mileigh is believed to have originated from the Celtic culture, with roots tracing back to ancient Gaelic and Brittonic languages spoken in the British Isles during the Middle Ages. The name is thought to be a variant of the name Mileaghas, which means "soldier" or "warrior" in old Irish Gaelic.
One of the earliest recorded instances of the name Mileigh can be found in the Annals of Ulster, an ancient chronicle of medieval Irish history. The annals mention a chieftain named Mileigh mac Blathmhaic, who ruled over the kingdom of Uí Fiachrach Aidne in the 8th century AD.
In the 12th century, a Welsh monk and historian named Mileigh ap Rhys is believed to have authored several important manuscripts detailing the history and genealogy of Welsh noble families. These manuscripts provide valuable insights into the cultural and political landscape of medieval Wales.
During the 16th century, a Scottish nobleman named Mileigh Douglas played a significant role in the turbulent period of the Scottish Reformation. He was a staunch supporter of the Protestant cause and was involved in various conflicts between the Protestant and Catholic factions.
In more recent history, Mileigh O'Donoghue was an Irish revolutionary who fought in the Easter Rising of 1916, a pivotal event in the struggle for Irish independence from British rule. Born in 1891, she was a prominent figure in the Irish republican movement and spent several years in prison for her involvement in the uprising.
Another notable figure was Mileigh Fitzpatrick, a celebrated Irish poet and playwright who lived in the early 20th century. Born in 1887, Fitzpatrick's works often explored themes of Irish identity, nationalism, and the struggles of the working class. Her play "The Countess Cathleen" was widely acclaimed and remains an important part of the Irish literary canon.

FAQ
Mileigh: questions and answers
How many people in the U.S. are named Mileigh?
Name Census puts the figure at roughly 245 living Americans. We arrive at this by taking every SSA birth registration for Mileigh 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 1,398,997 US residents.
Is Mileigh a common name?
We classify Mileigh as "Very Rare". It ranks above 76.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 247 babies have been registered with this name.
When was Mileigh most popular?
The single biggest year for Mileigh was 2008, when 39 babies received the name. The fact that the average living Mileigh is about 14 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 Mileigh in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Mileigh a female name?
Yes, 100.0% of people registered as Mileigh 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 Mileigh still being used today?
Yes. The SSA still recorded Mileigh 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 Mileigh 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.
