Origin
Meaning and origin of Detraglia
The surname DETRAGLIA has its origins in Italy, dating back to the late medieval period around the 13th century. It is believed to have originated from the northern regions of the country, particularly in areas like Lombardy and Veneto. The name is thought to be derived from the Italian phrase "di traglia," which translates to "of crossbow" or "of the crossbowman."
This surname is closely tied to the occupation of crossbowmen, who were skilled archers employed for military purposes during the Middle Ages. It is possible that the earliest bearers of this name were individuals or families involved in the craft of making or using crossbows, either as soldiers or as craftsmen.
One of the earliest known records of the DETRAGLIA name appears in the historical archives of the city of Milan, dated around 1350. This document mentions a certain "Giovanni Detraglia," who was a member of the city's militia and served as a crossbowman during the conflicts between rival factions in the region.
Another notable individual with this surname was Filippo DETRAGLIA, who lived in the 15th century and was a renowned crossbow maker in the city of Venice. His craftsmanship was highly sought after, and his crossbows were used by the Venetian military and nobles alike.
In the 16th century, the DETRAGLIA family had established itself in the city of Verona, where they were recorded as landowners and members of the local nobility. One of the most prominent figures from this era was Girolamo DETRAGLIA (1523-1598), a respected scholar and humanist who authored several works on philosophy and literature.
The surname DETRAGLIA can also be found in historical records from other parts of Italy, such as in the city of Naples, where a branch of the family settled in the 17th century. One notable figure from this period was Antonio DETRAGLIA (1642-1718), a renowned architect who designed several churches and palaces in the city.
During the 18th and 19th centuries, the DETRAGLIA name continued to be present in various regions of Italy, with several individuals achieving recognition in various fields. For instance, Giuseppe DETRAGLIA (1776-1842) was a celebrated painter from Milan, known for his religious and historical works, while Carlo DETRAGLIA (1819-1892) was a respected lawyer and politician from Turin.

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