Origin
Meaning and origin of Deprofio
The surname DEPROFIO has its origins in medieval Italy, specifically in the regions of Tuscany and Emilia-Romagna, dating back to the 13th century. The name is believed to be derived from the Italian phrase "de profio," which translates to "from the depth" or "from the abyss." This suggests that the earliest bearers of this surname may have lived in areas with deep valleys or ravines.
One of the earliest recorded instances of the DEPROFIO surname can be found in a document from the city of Siena, dated 1287, which mentions a certain Guglielmo DEPROFIO, a wool merchant. Another early reference is found in the Catasto of Florence from 1427, listing a family named DEPROFIO residing in the Oltrarno quarter.
In the 15th century, a branch of the DEPROFIO family relocated to the town of Brisighella, in the province of Ravenna, where they became prominent landowners and merchants. One notable member of this branch was Niccolò DEPROFIO (1495-1572), a renowned jurist and legal scholar who served as a judge in the papal courts.
During the Renaissance period, the DEPROFIO surname was also found in the city of Bologna, where a family of artists and architects resided. The most famous among them was Giacomo DEPROFIO (1510-1588), an architect who contributed to the design of several churches and palaces in Bologna and its surrounding areas.
In the 17th century, a DEPROFIO family settled in the town of Montepulciano, in the province of Siena. One of their descendants, Tommaso DEPROFIO (1678-1742), was a celebrated painter known for his religious works adorning many churches in Tuscany.
Another notable figure bearing the DEPROFIO surname was Antonio DEPROFIO (1805-1878), a military officer who fought in the Italian wars of independence and later became a general in the Kingdom of Italy.
Throughout its history, the DEPROFIO surname has maintained a strong presence in various regions of Italy, particularly in Tuscany, Emilia-Romagna, and Lazio, where it continues to be found today.

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