Origin
Meaning and origin of Warman
The surname Warman is of English origin and dates back to the medieval period. It is believed to have derived from the Old English words "waer" meaning "wary" or "cautious" and "man" referring to a person. This suggests that the name may have initially been used to describe someone who was perceived as a particularly vigilant or careful individual.
One of the earliest known references to the name Warman can be found in the Domesday Book of 1086, where it is recorded as "Wareman" in the county of Hertfordshire. This historical record suggests that the name was already in use in England by the late 11th century.
During the 13th century, the name appears to have been particularly prevalent in the counties of Norfolk and Suffolk, with various spellings such as "Warmann" and "Wareman" being recorded in local documents and records.
One notable bearer of the name was Sir John Warman, a Member of Parliament for the borough of Ipswich in Suffolk during the 15th century. He was born around 1420 and served as an MP in the Parliaments of 1449 and 1472.
Another early example of the name is found in the form of William Warman, who was born in the village of Wivenhoe, Essex, in the late 15th century. He became a prominent merchant and served as a bailiff (a local official) in the nearby town of Colchester in 1520.
In the 16th century, the Warman surname appears to have spread more widely across England, with records showing bearers of the name in counties such as Gloucestershire, Wiltshire, and Yorkshire. One notable figure from this period was John Warman, a clergyman who was born in Gloucestershire in 1530 and later became the Rector of Weston-sub-Edge in the same county.
During the 17th century, the Warman name continued to be found in various parts of England, with some bearers of the name migrating to the American colonies. One such individual was Edward Warman, who was born in Oxfordshire in 1620 and later settled in the Massachusetts Bay Colony, where he became a respected landowner and farmer.
Throughout the centuries, the Warman surname has been associated with various places and regions across England, including the village of Warmansworth (now called Warminster) in Wiltshire, which may have derived its name from an early bearer of the Warman surname.
Demographics
Ancestry and ethnicity for Warman

The bar chart below shows how Warman 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 Warman 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 Warman (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
