Origin
Meaning and origin of Siino
The surname SIINO is of Italian origin, believed to have emerged in the regions of Calabria and Sicily during the medieval period. It is thought to be derived from the Greek word "sinos," which translates to "damage" or "harm." This suggests that the name may have initially been a descriptive nickname for an individual or family associated with some form of destruction or misfortune.
One of the earliest recorded instances of the SIINO surname can be found in a 14th-century Sicilian document, where it appears as "Sino." This spelling variation likely reflects the influence of the local dialects and pronunciations of the time. The name is also believed to have connections to the ancient town of Siino, located in the province of Palermo, Sicily, which could have served as a source for the surname's origin.
During the 15th century, the SIINO name gained prominence in the region of Calabria, particularly in the town of Reggio Calabria. Records from this period mention a prominent figure named Girolamo SIINO, a nobleman and landowner who lived between 1435 and 1503. Girolamo's descendants continued to play influential roles in the local community for several generations.
In the 17th century, a notable individual bearing the SIINO surname was Francesco SIINO, a Catholic priest and scholar who was born in Messina, Sicily, in 1612. Francesco was renowned for his theological writings and his contributions to the intellectual discourse of the time. He passed away in 1682.
Another individual of note was Giuseppe SIINO, a military officer who served in the Napoleonic Wars during the early 19th century. Born in Palermo in 1785, Giuseppe rose through the ranks and eventually attained the position of colonel in the French Army. He was recognized for his bravery and leadership during numerous battles before his death in 1835.
In the late 19th century, the SIINO surname gained further recognition with the birth of Gaetano SIINO, a prominent Italian sculptor and artist. Born in Reggio Calabria in 1879, Gaetano's works were highly celebrated for their intricate details and exceptional craftsmanship. He is particularly renowned for his religious sculptures that adorned numerous churches throughout Italy. Gaetano SIINO passed away in 1952.
While the surname SIINO may have originated from humble beginnings, its bearers have left an indelible mark on various aspects of Italian history, ranging from nobility and military service to scholarly pursuits and artistic endeavors. The name's rich heritage spans centuries and serves as a testament to the enduring cultural legacy of the regions it once called home.

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.
