Origin
Meaning and origin of Gruppo
The surname Gruppo originated in Italy during the medieval period. It is believed to be derived from the Italian word "gruppo," which means "group" or "cluster." This suggests that the name may have been given to someone who lived in a group of houses or a small village.
One of the earliest recorded instances of the name Gruppo can be found in the Codice Diplomatico Longobardo, a collection of historical documents from the Lombard period in Italy, dating back to the 8th century. In this text, a person named Gruppo is mentioned as a landowner in the region of Tuscany.
During the 12th century, a family bearing the name Gruppo is documented in the city of Siena, where they were involved in the local wool trade. One notable member of this family was Guido Gruppo, who served as a magistrate in Siena in the year 1187.
In the 14th century, a branch of the Gruppo family settled in the town of Montepulciano, located in the province of Siena. Among the notable individuals from this lineage was Bartolomeo Gruppo, a skilled painter who lived between 1375 and 1446. Some of his works can still be found in churches and museums in the region.
Another prominent figure with the surname Gruppo was Francesco Gruppo, a Renaissance-era architect and sculptor who was born in Siena in 1490. He is best known for his contributions to the design of the Palazzo Pubblico in Siena, as well as several churches and palaces in the surrounding area.
During the 16th century, the Gruppo family expanded their influence beyond Tuscany. One member, Gian Paolo Gruppo, was a renowned jurist and legal scholar who served as a judge in the city of Bologna from 1532 to 1568.
Throughout the centuries, the surname Gruppo has maintained a presence in various parts of Italy, particularly in the regions of Tuscany, Umbria, and Lazio. While not a widely distributed name, it has endured as a part of Italy's rich cultural heritage.

The bar chart below shows how Gruppo bearers described their own race and ethnicity on the 2020 Census form. 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 Gruppo surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Gruppo (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
