Origin
Meaning and origin of Reggi
The surname Reggi has its origins in Italy, tracing back to the early medieval period around the 8th or 9th century. It is believed to have derived from the Old Italian word "reggia," meaning "royal" or "regal." This suggests that the name may have been initially associated with individuals who had some connection to royalty or the nobility.
One of the earliest recorded instances of the name Reggi can be found in the Codex Diplomaticus Cavensis, a collection of medieval documents from the Campania region of southern Italy, dating back to the 9th century. The name appears in various forms, such as "Regius" and "Regia," further reinforcing its regal connotations.
During the 12th century, the name Reggi gained prominence in the city of Florence, where a prominent family bearing this surname held significant influence and power. Records from this period mention several individuals with the name, including Guido Reggi, a influential merchant and banker who lived between 1180 and 1245.
As the centuries progressed, the Reggi surname spread across various regions of Italy, with notable bearers emerging in different areas. In the 15th century, Alessandro Reggi, a renowned scholar and poet from Padua, was celebrated for his literary works and contributions to the Renaissance era (1435-1510).
In the 17th century, the name gained further recognition with the birth of Antonio Reggi, a celebrated architect from Genoa, who was responsible for the design and construction of several notable buildings, including the Chiesa di San Giovanni Battista in Savona (1615-1696).
Another prominent figure bearing the Reggi surname was Giacomo Reggi, a distinguished military leader from Milan, who served in the armies of the Duchy of Milan during the Italian Wars of the 16th century (1490-1558).
While the surname Reggi has its roots deeply embedded in Italian history, it has since spread to other parts of the world through migration and the diaspora of Italian communities. However, its origins and associations with regality and nobility remain firmly rooted in the rich tapestry of Italian heritage.

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

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.
