Origin
Meaning and origin of Eudy
The surname EUDY is believed to have originated in Germany during the medieval period. It is thought to be derived from the Old High German word "eodu," which means "rich" or "prosperous." This suggests that the name may have been given to someone who was wealthy or lived in a prosperous region.
The earliest recorded instances of the name EUDY can be found in various historical documents from the 13th and 14th centuries. One notable example is in the Codex Diplomaticus Brandenburgensis, a collection of medieval charters and deeds from the region of Brandenburg, where the name appears as "Eudius" in a document dated 1292.
In the 15th century, the name EUDY was also found in records from the town of Nuremberg, where a certain Hans Eudy was mentioned in a guild register from 1478. This suggests that the name had spread to other parts of Germany by that time.
During the 16th and 17th centuries, the surname EUDY began to appear in various parts of Europe, likely due to migration and the spread of the Protestant Reformation. One notable example is Johann Eudy, a German theologian and philosopher who lived from 1533 to 1598.
As the name EUDY spread across Europe, it also underwent some variations in spelling. In England, for instance, it was sometimes written as "Eudey" or "Eadey," while in France it was occasionally recorded as "Eudier" or "Eudière."
Throughout history, there have been several notable individuals who bore the surname EUDY. One of the earliest was Johann Eudy, a German scholar and writer who lived from 1590 to 1656. Another was Matthias Eudy, a German composer and organist who was born in 1660 and died in 1720.
In the 19th century, the name EUDY gained prominence in the United States, particularly in the southern states. One notable figure was John Eudy, a soldier in the Confederate Army during the American Civil War, who served under General Robert E. Lee.
Another significant individual with the surname EUDY was William Eudy, an American businessman and philanthropist who lived from 1848 to 1922. He made his fortune in the textile industry and was known for his charitable contributions to various educational institutions.
Demographics
Ancestry and ethnicity for Eudy
Among Census respondents with the surname Eudy, the largest self-reported group is White at 94.5%. The next largest groups are Two or More Races (2.6%) and Hispanic (1.7%).
The bar chart below shows how Eudy 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 Eudy surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Eudy (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.
