Origin
Meaning and origin of Delsole
The surname Delsole has its origins in Italy, likely emerging in the 12th or 13th century during the Middle Ages. It is derived from the Italian words "del" meaning "of the" and "sole" meaning "sun." The name was likely given to someone who lived near a sunny location or had a sunny disposition.
One of the earliest recorded instances of the name Delsole can be found in the Codice Diplomatico, a collection of medieval documents from the city of Naples, dating back to the 13th century. The name appears in various spellings such as "del Sole," "de Sole," and "Delsoli."
In the 14th century, a notable figure with the name Delsole was Giovanni del Sole, a Neapolitan scholar and philosopher. He was known for his writings on logic and metaphysics, and his work influenced the intellectual landscape of the time.
During the Renaissance period, the Delsole family had a presence in various parts of Italy, including Tuscany and Umbria. One prominent member was Girolamo Delsole, a 16th-century painter from Perugia, known for his religious works and frescoes adorning churches in the region.
In the 17th century, a branch of the Delsole family settled in Sicily, where they became landowners and merchants. Notable figures from this period include Antonio Delsole, a wealthy merchant who traded with the Ottoman Empire, and Vincenzo Delsole, a renowned architect responsible for designing several churches and palaces in Palermo.
The name Delsole also found its way to other parts of Europe, particularly Spain and France. In the 18th century, a French nobleman named Louis Delsole served as a military officer and diplomat, representing the interests of the French crown in various European courts.
Throughout history, the Delsole family has produced several notable individuals, including artists, scholars, merchants, and military figures. While the name may have evolved in spelling and pronunciation over time, its connection to the sun and its Italian origins have remained a consistent theme.

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 Delsole 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 Delsole (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.
