Origin
Meaning and origin of Congi
The surname Congi has its origins in Italy, with records dating back to the 13th century. It is believed to have originated from the Italian word "congio," which meant a unit of measurement for liquids. This suggests that the name may have been associated with individuals involved in trades or occupations related to the measurement or distribution of liquids, such as wine or olive oil merchants.
One of the earliest known references to the name Congi can be found in a document from the city of Siena, dated 1278. This document mentions a certain Guido Congi, who was a merchant and landowner in the region. In the following centuries, the name appears in various historical records across different parts of Italy, including Tuscany, Umbria, and Lazio.
The Congi family seemingly had a strong presence in the town of Montefalco, located in the Umbria region. In the 15th century, a notable figure named Pietro Congi (1410-1478) was a prominent lawyer and served as a magistrate in Montefalco. His son, Francesco Congi (1445-1518), followed in his footsteps and became a renowned jurist and legal scholar.
During the Renaissance period, the name Congi gained further recognition through the works of the artist Bernardino Congi (1510-1594). Born in Siena, Bernardino was a talented painter who specialized in religious art and frescoes. Some of his notable works can be found in churches and monasteries throughout Tuscany.
In the 18th century, a branch of the Congi family settled in the city of Naples. Here, a prominent figure named Antonio Congi (1720-1788) made a name for himself as a successful merchant and banker. His son, Giuseppe Congi (1760-1832), followed in his footsteps and became a respected figure in the Neapolitan business community.
Another notable individual with the surname Congi was the writer and poet Girolamo Congi (1810-1879), who was born in the town of Spoleto, Umbria. His works, which included poetry collections and historical novels, were widely acclaimed during his lifetime and contributed to the preservation of local cultural traditions.
While the surname Congi may not be as widespread today as it once was, its historical roots and connections to various professions and artistic endeavors have left an indelible mark on Italian culture and heritage.

The bar chart below shows how Congi 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 Congi surname at the time of the 2020 Census, not any inherent property of the name itself.
