Origin
The surname Cornwell has its origins in England, tracing back to the 12th century. It is a locational surname derived from the Old English words "corn" meaning grain and "well" referring to a spring or stream, indicating that the name likely originated from a place where grain was grown near a water source.
One of the earliest recorded instances of the name appears in the Pipe Rolls of Berkshire in 1176, where it is listed as "Cornuuelle." This document suggests that the name was already established in the region during the 12th century.
The Domesday Book, compiled in 1086, does not directly mention the surname Cornwell, but it does list several places with names containing the element "corn," such as Cornwood in Devon and Cornhill in London, indicating the prevalence of these place names in England at the time.
In the 13th century, the surname appears in various records with variations in spelling, including "Cornewelle," "Cornuell," and "Cornualle." These variations reflect the evolution of the name over time and the regional differences in pronunciation and spelling.
One notable figure associated with the name Cornwell was Sir John Cornwell (c. 1470-1536), a prominent English landowner and Member of Parliament for Somerset during the reign of Henry VIII. He was known for his involvement in local affairs and his service to the Crown.
Another individual with the surname was Thomas Cornwell (1555-1625), an English clergyman and author who served as the Archdeacon of Taunton and wrote several religious works during the Elizabethan era.
In the 17th century, the name appears in the records of the Massachusetts Bay Colony, where families such as the Cornwells from Devonshire settled in the New World, bringing their surname with them.
During the 18th century, Edward Cornwell (1768-1831) was a notable English painter known for his landscapes and portraits. He exhibited his works at the Royal Academy and was highly regarded in his time.
In the 19th century, Frances Cornwell (1828-1894) was a British author and poet who wrote several novels and collections of poetry, contributing to the literary culture of the Victorian era.

Demographics
Among Census respondents with the surname Cornwell, the largest self-reported group is White at 87.3%. The next largest groups are Black (4.6%) and Two or More Races (3.9%).
The bar chart below shows how Cornwell 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 Cornwell 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 Cornwell (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.
