Origin
The surname Lucy originates from England and dates back to the Middle Ages. It is derived from the Old French personal name "Luce," which was a feminine form of the Latin name "Lucius." The name Lucius itself is believed to come from the Latin word "lux," meaning "light."
Lucy is considered a locational surname, indicating that the earliest bearers of the name likely came from a place called Lucy or Lucey. There are several villages and towns in England with this name, such as Lucy in Northamptonshire and Lucey in Somerset.
One of the earliest recorded instances of the surname Lucy can be found in the Domesday Book of 1086, which mentions a landowner named "Lucia" in Hampshire.
In the 13th century, a prominent figure named William Lucy was recorded as a nobleman and landowner in Warwickshire. He was born around 1230 and played a significant role in the Second Barons' War against King Henry III.
Another notable bearer of the surname was Sir Thomas Lucy, who lived from 1532 to 1605. He was an English Member of Parliament and is believed to have been the inspiration for the character Sir Thomas Lucy in William Shakespeare's play "The Merry Wives of Windsor."
Sir Spencer Lyle Lucy, born in 1816, was a British naval officer and explorer. He served in the Royal Navy and is known for his exploration of the Arctic regions.
In the literary world, Austen Lucy was a renowned English novelist who lived from 1874 to 1932. She is best known for her novel "The Masqueraders," published in 1904.
Henry W. Lucy, born in 1845, was a British journalist and author. He is remembered for his works on parliamentary life and his coverage of the British House of Commons.
Throughout history, the surname Lucy has been found in various spellings, such as Lucey, Lucie, and Luce, reflecting regional variations and linguistic influences.
Demographics
Among Census respondents with the surname Lucy, the largest self-reported group is White at 75.1%. The next largest groups are Black (16.7%) and Two or More Races (3.7%).
The bar chart below shows how Lucy 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 Lucy 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.
