Origin
Meaning and origin of Desimone
The surname DESIMONE has its origins in Italy, with the earliest records dating back to the 12th century. It is believed to have derived from the Italian words "de" meaning "from" and "Simone," which is the Italian form of the name Simon. This suggests that the surname may have initially referred to someone who was either from a place called Simone or was the son of someone named Simone.
The name was particularly prevalent in the regions of Campania and Lazio, where it is thought to have first emerged. Over time, various spelling variations arose, such as De Simone, Di Simone, and Desimoni, likely due to regional dialects and localized pronunciation differences.
One of the earliest documented references to the name can be found in the "Codice Diplomatico Barese," a historical record of legal documents from the city of Bari, dating back to the 13th century. This record mentions a certain "Riccardo Desimone" in the year 1268.
Another notable early example is Giovanni Desimone, a prominent jurist and legal scholar from Genoa, who lived in the 14th century. His works on maritime law were highly influential and helped shape the legal framework of maritime trade in the Mediterranean region.
During the Renaissance period, the name gained further recognition with the rise of several notable figures. Pietro Desimone, a Neapolitan architect and sculptor born in 1456, was responsible for the design and construction of several churches and palaces in Naples and its surrounding areas.
In the 16th century, Girolamo Desimone, a Sicilian philosopher and theologian, made significant contributions to the field of natural philosophy. His treatises on the nature of the universe and the relationship between faith and reason were widely studied and debated.
Moving into the 17th century, we encounter Gian Domenico Desimone, a renowned Italian composer and organist. Born in Naples in 1597, his compositions for the organ and sacred vocal works were highly regarded and performed throughout Italy during his lifetime.
As the centuries progressed, the name DESIMONE continued to be associated with various prominent individuals across various fields, including academia, the arts, and politics. However, it is important to note that this overview focuses on the historical origins and early notable bearers of the surname, rather than more recent or contemporary figures.

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 Desimone surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
