Origin
The surname Clardy has its origins in England and dates back to the 12th century. It is believed to have derived from the Old French word "clard," meaning "clear" or "bright." The name may have been initially given as a nickname to someone with a bright complexion or a cheerful disposition.
The earliest recorded instance of the Clardy surname can be found in the Pipe Rolls of Staffordshire in 1199, where it appears as "Clardey." This suggests that the name was already established in the region by the late 12th century.
During the Middle Ages, the Clardy surname was primarily concentrated in the counties of Staffordshire, Derbyshire, and Warwickshire. It is possible that the name originated from a place name, although no definitive records of such a place have been found.
In the 14th century, a notable reference to the Clardy surname appears in the records of the Chancery Court of Westminster. A certain John Clardy was involved in a legal dispute over land ownership in the year 1372.
One of the earliest known bearers of the Clardy surname was William Clardy, who was born in Derbyshire in the late 15th century. He was a prominent landowner and served as a magistrate in the county.
Another individual of historical significance was Sir Thomas Clardy (1520-1591), a Member of Parliament for Staffordshire during the reign of Queen Elizabeth I. He was also a prominent lawyer and served as a judge on the Court of Common Pleas.
In the 17th century, the Clardy surname gained recognition through the work of Richard Clardy (1612-1670), a renowned scholar and clergyman. He was the author of several theological works and served as the Archdeacon of Winchester.
During the English Civil War, Colonel John Clardy (1620-1678) was a notable military leader who fought for the Parliamentarian forces. He played a significant role in several battles and was later knighted for his service.
In the 18th century, the Clardy surname gained further prominence with the exploits of Captain James Clardy (1745-1821), a British naval officer who served during the Napoleonic Wars. He was commended for his bravery and leadership in several naval engagements.
While the Clardy surname has its roots in England, it has since spread to other parts of the world, including North America and Australia, through immigration and migration patterns.
Demographics
Among Census respondents with the surname Clardy, the largest self-reported group is White at 67.1%. The next largest groups are Black (23.8%) and Two or More Races (4.7%).
The bar chart below shows how Clardy 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 Clardy surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
