This article looks at how common Healy is as a last name in Ireland and the United States from the 19th century to the present day.
You’ll learn the meaning and origins of the Healy surname while exploring some notable and famous people that held it.
I use census records, emigration lists, and military archives to uncover fascinating patterns. If you’re studying your genealogy, check out my sources at the end of the post so you can do your own research.
How Common Is Healy As A Surname In Ireland?
Ireland does not disclose current statistics on surnames in much detail. The most that we get is the top ten last names in birth registrations for the previous year. Healy
Thankfully, an Irish genealogist named Seán Murphy studied the names in national phone books published in the 1990s. His estimates aren’t as accurate as a census, but they are still a good way to get an estimate of numbers.
Healy was ranked 61 in the top one hundred names in this decade with a total of 12,600 entries.
This graphic shows how it ranks compared to the 1st, 33rd, 66th, and 100th entries in the survey:

Healy In The Early 1900s
The only full censuses that are publically available in Ireland are from 1911 and 1901. Prior decades were either destroyed through government action (to reclaim storage space) or by a catastrophic fire during the Irish Civil War.
So, let’s focus on the early 1900s.
I used online archives to calculate the total numbers by surname. I consider these estimates due to some percentage of transcription errors. So, I’ve rounded the numbers to the nearest fifty.
There were 10,500 residents named Healy on the island in 1911.
Ten years earlier, Healy had about 10,450 residents in the 1901 census.
Population Estimates In The 1890s
A study of Irish surnames was conducted in 1890 by the head of the Civil Registrations Office. It was published as a “Special Report on Surnames In Ireland.”
The survey estimated that there were about 13,000 people named Healy in the country.
Emigration To America After The Irish Famine
The Irish have historically emigrated to Britain, the United States, Canada, and Australia. They were motivated by multiple factors, including social unrest, economic desperation, and hunger.
The largest wave of emigration to the United States occurred during the 19th century. The peak was in response to the Great Irish Famine, which took place between 1845 and 1852. A plant disease devastated the main food and income crop for much of the population.
I reviewed the Healy name in the shipping passenger lists arriving in New York during this period. The departures were from both Ireland and England.
This picture shows how the numbers rose and fell in the years after the famine:

How Common Is Healy As A Last Name In The U.S.?
Based on the 2010 U.S. census, the name Healy ranks about 1,796 among Irish names in America with 21,751 bearers.
Although the 2010 census has exact numbers and rankings, the rank I assign here is my estimate. If you’re curious about how I got there, here’s a brief explanation…
Estimating Rank In The United States
Historically, some Irish families with Gaelic surnames took English-sounding names as translations under the influence of colonization.
As these names also have English origins, they will have been brought to the United States by both British and Irish immigrants. Because the census doesn’t ask about specific European origin (e.g. England vs Ireland), it’s impossible to identify the proportion with Irish heritage.
I reviewed the census to identify which names are predominantly Irish in origin. In order to estimate the relative rankings of “Irish” names, I’ve mostly excluded surnames that have varying origins.
Healy In Historic Times
It is fascinating to examine how the prevalence of a surname shifts over the course of time in a country as young as the United States. As well as immigration, this reflects other demographic shifts across the nation. Factors include higher child mortality rates and longer life expectancy.
The historic census records have been transcribed and digitized. I used online archives to run counts of surname populations.
But the totals can’t be exactly accurate due to transcription errors. So, I’ve rounded the numbers to the nearest 50 in the graph below.
This picture shows the numbers every twenty years from 1860 to 1940:

These are the numbers in the graph:
- 1860: 2,350
- 1880: 5,100
- 1900: 9,000
- 1920: 12,100
- 1940: 14,500
Healy In World War II
During World War Two, approximately 8.3 million men and women joined the ranks of the United States Army. Many were of Irish descent. Some had even been born in Ireland and emigrated.
There were registration records for 827 soldiers named Healy who enlisted between 1938 and 1946.
There were 47 who were born in Ireland.
Healy Surname: Meaning And Origin
Healy comes from the Gaelic surname Ó hÉilidhe.
There are several theories concerning the early meaning. The scholar Patrick Woulfe wrote that it largely derives from the word ealadhach, which means scientific and clever. So, the full name means “descendant of the ingenious one”.
One Ó hÉilidhe family was prominent in Sligo and had their stronghold in a parish that became known as Ballyhealy. There was a separate strong Healy family in Munster.
