Origin
Meaning and origin of Siraco
The surname SIRACO has its origins in Italy, with the earliest records dating back to the 13th century. It is believed to have derived from the Italian word "siraco," which means "from Syracuse," a city in Sicily. This suggests that the name may have originated from individuals who migrated from Syracuse or the surrounding regions.
During the medieval period, the SIRACO name appeared in various records and manuscripts, including tax rolls and land deeds. One of the earliest mentions can be found in the Catasto Onciario, a tax record compiled in the Kingdom of Sicily in the late 15th century, where several individuals with the surname SIRACO were listed as landowners or taxpayers.
In the 16th century, a notable figure with the SIRACO surname was Pietro SIRACO (1510-1579), a Sicilian painter and architect who made significant contributions to the Renaissance art scene in Italy. His works can be found in churches and palaces throughout Sicily and southern Italy.
Another prominent individual was Giuseppe SIRACO (1677-1755), a Neapolitan jurist and legal scholar who served as a judge and wrote extensively on civil law. His treatises on legal matters were widely influential during his time and are still referenced by legal historians today.
In the 18th century, the SIRACO name gained further recognition with the birth of Vincenzo SIRACO (1737-1815), a celebrated Sicilian composer and musician. He composed several operas and sacred works, many of which were performed in major theaters and churches across Italy.
Moving into the 19th century, one notable figure was Maria SIRACO (1812-1888), a poet and writer from Calabria. Her collection of poems, titled "Canti della Terra Natia" (Songs of the Native Land), celebrated the beauty of her homeland and became widely popular among Italian literary circles.
Another individual of note was Giovanni SIRACO (1845-1921), a prominent banker and financier from Naples. He played a significant role in the development of the banking industry in southern Italy and was instrumental in establishing several financial institutions in the region.
These are just a few examples of individuals with the surname SIRACO who left their mark on various fields throughout history, demonstrating the rich heritage and legacy associated with this Italian name.

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