Origin
The surname Sheerin has its origins in Ireland, with the earliest recorded examples dating back to the 16th century. It is derived from the Gaelic word "sìthean," which means "fairy mound" or "hill of the fairies." This suggests that the name was originally given to someone who lived near or was associated with a fairy mound or hill.
The name Sheerin can be traced back to County Cavan in Ulster, where it was particularly prevalent. It is believed to have originated in the Baronies of Cavan and Loughtee, where several townlands and placenames contain variations of the name, such as Sheerinagh and Sheerinclone.
In the Annals of Ulster, a historical chronicle of medieval Ireland, there are references to individuals with the surname Sheerin as early as the late 16th century. One notable entry from 1597 mentions a "Donell O'Sherin" who was involved in a conflict with the English forces in Ulster.
One of the earliest recorded individuals with the surname Sheerin was Patrick Sheerin, who was born in County Cavan around 1650. He was a prominent landowner and is mentioned in the Hearth Money Rolls of 1665, a tax record of the time.
Another notable figure was James Sheerin (1745-1817), a merchant and shipowner from Belfast who played a significant role in the city's economic growth during the late 18th and early 19th centuries.
In the 19th century, a branch of the Sheerin family settled in County Tyrone, where John Sheerin (1824-1901) became a prominent figure in the local community. He served as a magistrate and was actively involved in the development of the town of Dungannon.
The name Sheerin also appears in historical records related to the Irish diaspora. One example is Michael Sheerin (1855-1924), who emigrated from Ireland to the United States and became a successful businessman and politician in New York City.
Throughout its history, the surname Sheerin has been associated with various occupations, including landowners, merchants, politicians, and community leaders, reflecting the diverse backgrounds of those who bore the name.
Demographics
Among Census respondents with the surname Sheerin, the largest self-reported group is White at 92.8%. The next largest groups are Two or More Races (3.3%) and Hispanic (1.6%).
The bar chart below shows how Sheerin 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 Sheerin 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 Sheerin (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.
