Origin
Meaning and origin of Haddox
The surname HADDOX is believed to have originated in England, likely in the county of Cheshire or the surrounding areas. It is thought to be a locational name, derived from a place name that no longer exists or has been lost to history.
One theory suggests that HADDOX may have its roots in the Old English words "hæd" meaning "heath" or "heathland" and "hock" meaning "a hook-shaped piece of land." This could indicate that the name originated from a place near a hook-shaped area of heathland or moorland.
Another possibility is that HADDOX is a variant spelling of the surname HADDOCK, which is believed to have originated from the Old English personal name "Hæddi" or "Hæddic," combined with the word "ock" meaning "hill" or "ridge."
While there are no definitive historical records of the surname HADDOX itself, some of the earliest recorded instances of similar surnames can be found in the Domesday Book of 1086. This influential document includes entries for individuals with surnames such as Hadoc and Haddoc, which may be related to the later HADDOX.
One of the earliest known individuals with the surname HADDOX was William Haddox, who was recorded in the parish records of Prestbury, Cheshire, in 1591. Another early example is Thomas Haddox, whose son John was baptized in the village of Malpas, Cheshire, in 1612.
In the 17th century, the HADDOX surname appeared in various records across Cheshire and neighboring areas, including references to John Haddox of Middlewich (born around 1630) and Richard Haddox of Nantwich (born around 1650).
One notable individual with the HADDOX surname was Sir Richard Haddox (1629-1719), a prominent lawyer and judge who served as Chief Justice of the Common Pleas in England from 1687 to 1689.
Another historical figure was John Haddox (1743-1821), a British naval officer who served during the Napoleonic Wars and was awarded the prestigious Naval Gold Medal for his bravery during the Battle of Copenhagen in 1801.
In the 19th century, the HADDOX surname spread beyond its traditional English roots, with individuals bearing the name appearing in records in other parts of the United Kingdom and even in North America.

The bar chart below shows how Haddox 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 Haddox 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 Haddox (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.
