Origin
Meaning and origin of Rupolo
The surname RUPOLO originates from Italy, specifically the region of Veneto, and dates back to the 12th century. It is derived from the Italian word "rupolo," which means "small rock" or "pebble." This suggests that the name may have originated from a place name or a descriptive nickname given to someone who lived near a rocky area or had a connection to the stone industry.
The earliest recorded instances of the RUPOLO surname can be found in various historical documents, such as the Ecclesiastical Archives of Vicenza, dating back to the late 12th century. These records mention individuals with variations of the spelling, including Rupolo, Rupolino, and Rupoletti.
In the 14th century, the RUPOLO family played a significant role in the city of Vicenza, with several members holding prominent positions in the local government and participating in the city's political and cultural life. One notable figure from this period was Giovanni Rupolo (1320-1385), a renowned architect who designed several churches and public buildings in Vicenza and the surrounding areas.
During the Renaissance period, the RUPOLO surname gained further recognition through the work of the sculptor and architect Andrea Rupolo (1460-1522). He was commissioned to create several important works, including the magnificent Loggia del Capitaniato in Vicenza, which is still admired today for its intricate stone carvings and architectural beauty.
In the 17th century, the RUPOLO family expanded beyond Veneto, with some members establishing themselves in other parts of Italy. One notable figure from this time was Martino Rupolo (1625-1691), a skilled engraver and printmaker who worked in Rome and produced numerous religious and allegorical works that are now housed in various museums and private collections.
Another significant individual bearing the RUPOLO surname was Giambattista Rupolo (1780-1845), a renowned painter from Verona who specialized in portraiture and genre scenes. His works were highly sought after by the nobility and wealthy patrons of his time, and his paintings can be found in prestigious galleries and museums across Italy.
Throughout its history, the RUPOLO surname has been associated with the skilled craftsmanship of stoneworking, architecture, and the arts. While not as widely known as some other Italian surnames, it has left its mark on the cultural and artistic heritage of Italy, particularly in the regions of Veneto and Verona.

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.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
