Origin
The surname DEYO originated in France and is an occupational name derived from the Old French word "dieu" meaning "God". It was initially given to clergymen or those who worked in religious services.
The earliest recorded example of the DEYO name dates back to the 12th century in the region of Normandy, France. It was spelled in various ways such as Dieu, Dyo, Dyo, and Dieyo before evolving into the modern spelling of DEYO.
In the 13th century, a record of a Jean Dieu was found in the town of Rouen, Normandy. This suggests that the name had already spread across the region during that time.
The name DEYO made its way to England during the Norman Conquest of 1066. One of the earliest recorded instances in England was in the Domesday Book of 1086, which listed a landowner named Radulfus Dieu in Lincolnshire.
Notable people with the surname DEYO throughout history include:
1. Pierre Deyo (1620-1687), a French Huguenot who immigrated to New Netherland (present-day New York) in the 17th century and became one of the founders of the village of New Paltz.
2. Moses Deyo (1755-1825), an American military officer who served in the Continental Army during the American Revolutionary War.
3. John Deyo (1771-1846), a United States Representative from New York who served in the House of Representatives from 1821 to 1823.
4. Jean-Baptiste Deyo (1793-1860), a French painter known for his landscapes and depictions of rural life in Normandy.
5. Albert Deyo (1887-1962), an American baseball player who played in the Major Leagues for the Boston Braves and the Philadelphia Phillies in the early 20th century.
The DEYO surname has also been associated with several place names, particularly in France and the United States. For example, the village of Deyo in the Normandy region of France is believed to have derived its name from the DEYO family who once lived there.
Demographics
Among Census respondents with the surname Deyo, the largest self-reported group is White at 87.5%. The next largest groups are Two or More Races (4.4%) and Black (3.7%).
The bar chart below shows how Deyo 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 Deyo 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.
