Origin
The surname Coughlin originates from Ireland and is derived from the Gaelic personal name Ó Cochlain, meaning "descendant of Cochlain." The name Cochlain is a diminutive form of the Irish word "coch," which means "hog" or "red." The name likely referred to a person with reddish hair or complexion.
The name Coughlin can be traced back to County Cavan in the northern part of Ireland, where it was particularly prevalent in the medieval period. The Coughlin family was part of the Ui Briuin Breifne, a powerful dynasty that ruled over parts of modern-day counties Cavan and Leitrim.
One of the earliest recorded references to the name Coughlin can be found in the Annals of Ulster, a chronicle of medieval Irish history. The annals mention a "Cochlin O'Breslin" in the year 1335, indicating the name's existence in the 14th century.
In the 16th century, during the Tudor conquest of Ireland, many Coughlin families were dispossessed of their lands and forced to relocate to other parts of the country. This led to the spread of the name across Ireland, particularly in counties like Armagh, Monaghan, and Louth.
Notable individuals with the surname Coughlin throughout history include:
1. Terence Coughlin (c. 1534-1589), an Irish Catholic priest who was martyred during the reign of Queen Elizabeth I for his religious beliefs.
2. Patrick Coughlin (1761-1849), an Irish-born soldier who fought in the American Revolutionary War and later settled in Pennsylvania.
3. Dennis Joseph Coughlin (1865-1936), an American Catholic prelate who served as the Bishop of Jaffna in Sri Lanka from 1924 to 1936.
4. James Coughlin (1887-1967), an American baseball player who played for the Philadelphia Athletics and the Detroit Tigers in the early 20th century.
5. Charles Coughlin (1891-1979), an American Catholic priest and controversial radio host known for his anti-Semitic and pro-fascist views during the Great Depression era.
While the Coughlin name has its roots in Ireland, it has since spread to various parts of the world, particularly through Irish immigration to countries like the United States, Canada, and Australia.
Demographics
Among Census respondents with the surname Coughlin, the largest self-reported group is White at 92.9%. The next largest groups are Hispanic (3.2%) and Two or More Races (2.5%).
The bar chart below shows how Coughlin bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Coughlin surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Coughlin (2000, 2010, 2020).
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
