Origin
Meaning and origin of Schiaffo
The surname SCHIAFFO originated in Italy during the medieval period. It is derived from the Italian word "schiaffo," which means "slap" or "blow." This surname likely arose as a nickname for someone who had a tendency to strike others or had a boisterous and aggressive demeanor.
The earliest recorded instances of the SCHIAFFO surname can be traced back to the 13th century in the region of Tuscany. Historical records from this time period mention individuals bearing variations of the name, such as Schiaffi, Schiaffini, and Schiaffone.
One of the earliest documented references to the SCHIAFFO name can be found in a manuscript from the city of Siena, dated 1287. This document mentions a certain Gherardo Schiaffi, who was a local merchant and landowner.
During the Renaissance period, the SCHIAFFO surname gained prominence in the city of Florence. In the 15th century, a family by the name of Schiaffino was known for their skilled craftsmanship in the art of metalworking. Notable members of this family include Giovanni Schiaffino (1437-1510), a renowned goldsmith and sculptor, and his son, Bartolomeo Schiaffino (1470-1538), who continued the family's metalworking tradition.
In the 16th century, the SCHIAFFO surname was also present in the city of Venice. Historical records from this time mention a scholar named Pietro Schiaffo (1525-1602), who was renowned for his expertise in classical literature and philosophy.
As the SCHIAFFO surname spread across Italy, it also found its way into other regions and countries. In the 17th century, a branch of the family settled in the Spanish city of Barcelona, where they adopted the spelling Schiafino. One notable individual from this line was Juan Antonio Schiafino (1675-1743), a respected lawyer and magistrate.
Throughout the centuries, the SCHIAFFO surname has been associated with various professions and fields of endeavor. From artists and craftsmen to scholars and lawyers, individuals bearing this name have left their mark on the cultural and intellectual fabric of their respective communities.

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