Origin
The surname QUIRK is of English origin, derived from the Old English word "cwirc" or "cwirce," meaning a sharp turn or twist. It is believed to have originated as a descriptive nickname for someone with a peculiar or eccentric habit or characteristic.
QUIRK first appeared in historical records in the late 13th century. One of the earliest recorded instances is found in the Hundred Rolls of Gloucestershire, dating back to 1273, where a person named William Quirk was mentioned.
In the 14th century, the surname was often spelled as "Qwyrke" or "Qwyrkke," reflecting the evolution of the English language and spelling conventions at the time.
The QUIRK surname has been associated with several notable figures throughout history. In the 16th century, John Quirk (c. 1560-1634) was a prominent English clergyman and author who wrote several theological works.
During the English Civil War, Edward Quirk (c. 1620-1688) was a Puritan preacher and supporter of the Parliamentary cause. He was known for his fiery sermons and political activism.
In the 18th century, John Quirk (1701-1765) was an English engraver and artist who produced numerous engravings and illustrations for books and publications.
In the 19th century, Sir John Quirk (1828-1904) was a British naval officer and explorer. He participated in several Arctic expeditions and was knighted for his contributions to navigation and exploration.
Another notable figure was Mary Ann Quirk (1830-1912), an Irish-American educator and activist. She founded several schools and organizations dedicated to promoting education and women's rights in the United States.
Over time, the QUIRK surname has also been associated with various place names in England, such as Quirk's Farm in Dorset and Quirk's Hill in Lancashire, reflecting the geographical spread of families bearing this name.
Demographics
Among Census respondents with the surname Quirk, the largest self-reported group is White at 92.1%. The next largest groups are Hispanic (3.3%) and Two or More Races (2.8%).
The bar chart below shows how Quirk 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 Quirk 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 Quirk (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.
