Origin
Meaning and origin of Siccardi
The surname Siccardi originated in Italy during the medieval period. It is derived from the Italian word "secco," which means "dry" or "arid." The name likely referred to an individual who lived in an area with a dry or arid climate or perhaps a person with a dry or emaciated appearance.
The earliest known record of the Siccardi surname dates back to the 13th century in the region of Piedmont, located in northwestern Italy. It is believed that the name first emerged in the town of Siccardi, a small village near the city of Asti.
In the 14th century, the Siccardi family gained prominence in the nearby city of Alba, where they were involved in the local government and held influential positions. One notable member was Giovanni Siccardi, who served as the mayor of Alba in the late 1300s.
During the Renaissance period, the Siccardi family expanded their reach beyond the Piedmont region. In the 16th century, Francesco Siccardi, a renowned artist and sculptor, was commissioned to create several works for the Basilica di San Pietro in Rome.
In the 18th century, the Siccardi family produced several notable scholars and writers. Giuseppe Siccardi (1718-1792) was a professor of law at the University of Turin and authored several influential legal texts. His nephew, Carlo Siccardi (1760-1835), was a renowned poet and playwright whose works were widely celebrated in literary circles.
As the Siccardi family continued to prosper, they established themselves in various parts of Italy, including Tuscany, Lombardy, and Sicily. In the 19th century, Antonio Siccardi (1822-1897) was a prominent politician and statesman who served as the Minister of Justice in the Kingdom of Italy.
While the Siccardi surname is still found throughout Italy today, it has also spread to other parts of the world through immigration. However, its origins can be traced back to the medieval era in the Piedmont region of northern Italy, where the name first emerged and gained significance.

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