This article looks at how common McLaughlin 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 McLaughlin 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 McLaughlin As A Surname In Ireland?
The Irish government doesn’t publish detailed surname statistics for recent years. The best that they give us is the ten most common surnames of babies born in the previous year. McLaughlin
So, I had to look elsewhere for population estimates. Thankfully, an Irish genealogist researched the prevalence of Irish surnames through national phone directories published in the 1990s. Seán Murphy’s estimates aren’t as robust as a census but give a good broad estimate.
McLaughlin was ranked 19 in the top one hundred names in this decade with a total of 21,600 entries.
This graphic shows how it ranks compared to the 1st, 33rd, 66th, and 100th entries in the survey:
McLaughlin In The Early 1900s
The only complete Irish censuses that are available to the general public are those from the years 1901 and 1911. They offer two detailed snapshots of the population.
Some records exist from earlier censuses, but most of the documents are lost to history. So, we’ll focus on the turn of the century.
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 7,800 residents named McLaughlin on the island in 1911.
Ten years earlier, McLaughlin had about 7,300 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 17,500 people named McLaughlin 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 McLaughlin 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 McLaughlin As A Last Name In The U.S.?
Based on the 2010 U.S. census, the name McLaughlin ranks about 437 among Irish names in America with 74,816 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.
McLaughlin 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: 11,950
- 1880: 20,200
- 1900: 29,850
- 1920: 36,650
- 1940: 43,600
McLaughlin 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 2,931 soldiers named McLaughlin who enlisted between 1938 and 1946.
There were 31 who were born in Ireland.
McLaughlin Surname: Meaning And Origin
McLaughlin comes from the Gaelic surname Mac Lochlainn. The “Mac” in Irish names literally means “son of”, so the name means “son of Lochlann”.
The personal name Lochlann derives from the word for Viking or Norseman. So, the full name means “son of the Norseman”.
Early bearers of the name were once the most powerful family in Ulster. Their stronghold in medieval times was in what is now County Donegal.
Famous Or Historic People Named McLaughlin
Here are some notable people with the family name:
- Bernard McLaughlin (1921 – 1961): Bernard and his brothers, Punchy and Little George, led the notorious McLaughlin Brothers gang in Charlestown and the wider New England region. After starting a gang war (known as the Boston Irish Gang War) with the Winter Hill Gang, Buddy was shot dead.
- Alford McLaughlin (1928 – 1977): a Marine Corps master sergeant who received the Medal of Honor for bravery for his actions during the Battle of Bunker Hill.
The Ireland 1990s estimates are from Seán J. Murphy’s research paper.
The population estimates of 1890 are based on the “Special Report on Surnames in Ireland“, published in 1909.
The population figures for the 2010 U.S. Census come from a file provided by the U.S. Census Bureau.
Some of the population numbers are based on my own research and calculations using online archives. I’ve rounded those numbers to the nearest 50 to account for transcription errors and other technical issues with online databases of this type.

I plotted the emigration figures from 1845 to 1854 based on calculations from the archives of the New York Passenger Lists (1820-1957).
