Origin
The surname DIODONET has its origins in France, first emerging during the early Middle Ages around the 9th century. It is believed to have derived from the Occitan or Provençal dialect word "diodune," which referred to a small, fortified town or settlement. This suggests that the name may have initially been a locative or toponymic surname, indicating an individual's place of origin or residence.
One of the earliest recorded instances of the DIODONET surname can be found in the Cartulaire de Marseille, a collection of medieval charters and documents from the city of Marseille, dating back to the 11th century. The name appears as "Diodunetus" in these records, reflecting its Occitan roots and the linguistic evolution of the name over time.
During the High Middle Ages, the DIODONET surname was prevalent in the southern regions of France, particularly in the areas around Marseille and Provence. It was not uncommon for surnames to undergo variations in spelling and pronunciation as they spread to different regions and were influenced by local dialects.
In the 13th century, a notable figure bearing the DIODONET surname was Guilhem Diodonet, a troubadour and poet from the town of Beaucaire in Languedoc. His works, which primarily focused on courtly love and chivalric themes, have been preserved and studied by scholars of medieval literature.
Another historical reference to the DIODONET surname can be found in the Livre des Connaissances, a medieval French encyclopedia compiled in the late 13th century. This work mentions a certain "Pierre Diodonet," who was a renowned physician and scholar in the city of Montpellier during that period.
Moving into the Renaissance era, a prominent individual with the DIODONET surname was Jean Diodonet (1506-1572), a French Protestant theologian and reformer. He played a significant role in the spread of Calvinism in the Dauphiné region and authored several influential theological works.
In the 18th century, Louis Diodonet (1725-1798) was a notable French architect and urban planner. He was responsible for designing and overseeing the construction of several notable buildings and urban projects in Paris and other cities during his lifetime.
While the DIODONET surname has its roots in France, it has also been found in other parts of Europe over the centuries, potentially due to migration and intermarriage. However, the name's strong historical ties to southern France and its Occitan linguistic origins remain a defining characteristic of its etymology and evolution.
Demographics
Among Census respondents with the surname Diodonet, the largest self-reported group is Hispanic at 92.2%. The next largest groups are Black (4.4%) and White (2.9%).
The bar chart below shows how Diodonet 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 Diodonet 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.
