Origin
The surname FONDER is believed to have originated in France during the 12th century. It is derived from the Old French word "fonder," which means "to establish" or "to found." The name was likely given to someone who established a new settlement or played a significant role in the founding of a town or village.
One of the earliest recorded instances of the name FONDER can be found in a medieval French manuscript from the year 1247, which mentions a person named Jean Fonder. This document suggests that the name was already in use during the 13th century.
In the 14th century, the FONDER surname appeared in several historical records, including the "Livre des Métiers" (Book of Trades) in Paris, where it was associated with various occupations related to construction and building.
During the 16th century, the FONDER family was well-established in the province of Normandy, France. One notable figure from this period was Pierre Fonder (1522-1591), a prominent merchant and landowner who played a crucial role in the local economy.
As the FONDER family spread across Europe, the spelling of the name evolved slightly. In England, it was sometimes written as "Founder," while in Germany, it appeared as "Funder" or "Fonder."
One of the most famous individuals with the surname FONDER was Marie-Anne Fonder (1729-1808), a French novelist and playwright who gained recognition for her works during the Enlightenment period.
In the 19th century, the FONDER name was carried to the Americas by French and German immigrants. One notable American with this surname was William Fonder (1835-1912), a businessman and philanthropist who established several charitable foundations in New York City.
Another prominent figure with the FONDER surname was Jacques Fonder (1872-1948), a French architect who designed several iconic buildings in Paris, including the Palais de Chaillot and the Théâtre des Champs-Élysées.
The FONDER surname has a rich history spanning centuries and continents, with its origins firmly rooted in the French language and culture. While the name may have evolved in spelling and pronunciation over time, its connection to the concept of founding or establishing remains a constant thread throughout its remarkable journey.
Demographics
Among Census respondents with the surname Fonder, the largest self-reported group is White at 72.7%. The next largest groups are Black (15.5%) and Hispanic (5.1%).
The bar chart below shows how Fonder 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 Fonder 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 Fonder (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.
