Origin
The surname COY has its origins in the Old French word "coi" or "quoi", meaning quiet, still, or peaceful. It is believed to have been initially used as a nickname for someone with a calm or reserved demeanor. The name's earliest known roots can be traced back to the northern regions of France, particularly in the areas of Normandy and Picardy, during the 12th and 13th centuries.
One of the earliest recorded instances of the surname COY can be found in the Domesday Book of 1086, where a landowner named Radulfus le Coy was listed as holding a manor in the county of Hertfordshire, England. This suggests that the name had already been established in France and subsequently adopted in England by the time of the Norman Conquest in 1066.
The surname COY has undergone various spelling variations throughout history, including Coye, Coy, Coie, and Coyse. These variations can often be attributed to regional dialects and the inconsistencies in historical record-keeping. Additionally, the name has been associated with several place names, such as the village of Cuy in the Pas-de-Calais region of northern France, which may have influenced the surname's evolution.
Notable individuals bearing the surname COY include:
1. Geoffrey Coy (c. 1450 - 1512), an English lawyer and member of the Parliament during the reign of Henry VII.
2. Robert Coy (1594 - 1672), an English Puritan clergyman and writer who served as the rector of Boxwell in Gloucestershire.
3. Jean-Baptiste Coy (1756 - 1827), a French artist and engraver known for his portraits and historical paintings.
4. Eliza Ann Coy (1829 - 1905), an American educator and activist who founded the Coy Boarding School for Girls in Ypsilanti, Michigan.
5. John Thomas Coy (1856 - 1937), a British engineer and inventor, best known for his contributions to the development of the modern bicycle.
Throughout its long history, the surname COY has been widely dispersed across various regions, reflecting the migration patterns and cultural influences that have shaped its legacy.
Demographics
Among Census respondents with the surname Coy, the largest self-reported group is White at 79.4%. The next largest groups are Hispanic (10.8%) and Black (4.9%).
The bar chart below shows how Coy 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 Coy 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 Coy (2000, 2010, 2020).
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.
