Origin
The surname Conlin is of Irish origin, tracing its roots back to the 7th century. It is an Anglicized version of the Gaelic name O'Conallan or O'Conaleen, which means "descendant of the wolf." The name is believed to have originated in County Galway, where it was common among families in the region.
Historically, the name Conlin has been recorded in various forms, including Conallan, Conlan, and Connollan. One of the earliest documented instances of the name appears in the Annals of the Four Masters, a chronicle of medieval Irish history compiled in the 17th century. It mentions a figure named Conallan, who was a leader of the Uí Fiachrach Aidne clan in the 8th century.
In the 11th century, the Conlin name was associated with a notable family in County Mayo. Records from this time indicate that a prominent figure named Conallan O'Conallan held a significant position within the local community. Additionally, the name is found in the Pipe Rolls of Cloyne, a collection of administrative records from the 13th century, which mentions a person named Richard Conlyne.
One of the earliest recorded instances of the Conlin surname in its modern spelling can be traced back to the 16th century. In 1543, a document from the Chancery Rolls in Ireland mentions a person named John Conlyn. Another notable figure from this era was Robert Conlin, a landowner and merchant from County Antrim, who lived in the late 16th and early 17th centuries.
Throughout history, several individuals with the Conlin surname have gained recognition in various fields. One notable example is John Conlin (1803-1888), an Irish-born American Catholic priest who served as the first Bishop of Milwaukee. Another prominent figure was William Conlin (1866-1940), an American journalist and newspaper editor who worked for the Philadelphia Evening Bulletin.
In the realm of literature, Francis Conlin (1891-1969) was an Irish-born American author and academic who wrote extensively on Irish literature and culture. Additionally, John Conlin (1927-2012) was a renowned American composer and music educator, best known for his contributions to choral music.
The Conlin name has also been associated with notable figures in sports. For instance, Jesse Conlin (born 1986) is an American professional baseball player who has played for several Major League Baseball teams, including the Oakland Athletics and the Houston Astros.
Demographics
Among Census respondents with the surname Conlin, the largest self-reported group is White at 94.5%. The next largest groups are Hispanic (2.3%) and Two or More Races (2.1%).
The bar chart below shows how Conlin 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 Conlin surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
