Origin
Meaning and origin of Hardcastle
The surname Hardcastle is of English origin, deriving from the Old English words "heard" meaning "hardy" or "brave" and "castel" meaning "castle" or "fortified place." It is believed to have originated in the 12th or 13th century as a descriptive name referring to either a person who lived in a fortified castle or someone who had a reputation for being bold or courageous.
One of the earliest recorded instances of the name Hardcastle appears in the Pipe Rolls of Yorkshire in 1379, where it is spelled "Herdcastell." This provides evidence that the name was present in England during the late Middle Ages. Additionally, the Domesday Book of 1086 mentions several places with similar names, such as "Herdcasfel" and "Herdcasfelda," which could be related to the origins of the surname.
The variant spelling "Hardcastell" is found in records from the 16th century, including in the Subsidy Rolls of Yorkshire in 1545. This spelling likely reflects the pronunciation of the name at that time.
Notable individuals who have borne the surname Hardcastle include Sir Robert Hardcastle (1564-1631), an English politician and Member of Parliament for Hertford in the early 17th century. Another prominent figure was William Hardcastle (1793-1854), a British architect and civil engineer who designed several notable buildings in London.
In the realm of literature, one of the most famous bearers of the name was Mrs. Hardcastle, a character in Oliver Goldsmith's 1773 play "She Stoops to Conquer." This fictional character, known for her humorous misunderstandings, has become a cultural icon and helped to popularize the surname.
Other notable individuals with the surname Hardcastle include Edward Hardcastle (1828-1892), a British industrialist and founder of the Hardcastle Thread Company, and William Hardcastle (1839-1918), a Welsh architect who designed several churches and public buildings in Wales.
While the surname Hardcastle is not as common as some other English surnames, it has a rich history dating back to the Middle Ages and has been borne by individuals from various walks of life, including politicians, architects, and literary figures.

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 Hardcastle 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 Hardcastle (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.
