Origin
Meaning and origin of Stolfo
The surname STOLFO is of Italian origin, tracing its roots back to the northern regions of the country, particularly the areas around Venice and Treviso. It is believed to have emerged in the late Middle Ages, around the 13th or 14th century.
One of the earliest recorded instances of the name can be found in the historical records of the Republic of Venice, where a Pietro Stolfo is mentioned as a merchant and landowner in the year 1387. This suggests that the name was already well-established in the region at that time.
The surname STOLFO is thought to be derived from the Italian word "stolfo," which means "stubborn" or "obstinate." This could indicate that the name was originally given as a descriptive nickname to someone who exhibited these traits. It is also possible that the name evolved from a place name or was an occupational surname, but records from that era are scarce.
In the 15th century, there are records of a Matteo Stolfo, a renowned architect and sculptor who worked on several notable buildings in Venice, including the Doge's Palace. His birth and death dates are unknown, but his legacy lives on in the architectural wonders of the city.
Another notable figure bearing the surname was Giovanni Battista Stolfo, a 16th-century physician and scholar from Treviso. He is known for his contributions to the study of medicine and his writings on various subjects, including philosophy and theology. He lived from 1525 to 1592.
During the Renaissance period, the name STOLFO appears to have spread beyond its northern Italian roots. In the late 16th century, a Francesco Stolfo is recorded as a painter and fresco artist who worked in Rome and other parts of central Italy. His exact dates are uncertain, but his works can still be seen in various churches and palaces across the region.
In the 18th century, a notable figure bearing the surname was Antonio Stolfo, a Venetian composer and musician who was active in the early part of the century. His compositions included operas, sacred works, and instrumental pieces, but unfortunately, little is known about his personal life or specific dates.
As the surname spread throughout Italy and beyond, it underwent various spelling variations, such as Stolfio, Stolfi, and Stolfo, but the core pronunciation and meaning remained largely unchanged. While not as common as some other Italian surnames, the name STOLFO has left its mark on the historical and cultural fabric of the country.

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