Origin
The surname Colecchi is of Italian origin, tracing its roots back to the central regions of the country during the medieval period. It is believed to have originated as a habitational name, derived from a place name or a topographic feature.
One possible source of the name Colecchi could be the Italian word "colle," meaning hill or small mountain. This suggests that the earliest bearers of this surname may have resided near or on a hillside or elevated terrain. Alternatively, it could be derived from the Latin word "collis," which also translates to hill or mound.
Historical records indicate that the Colecchi name was present in the Italian region of Umbria as early as the 13th century. In a document dated 1276, a certain Gio Colecchi is mentioned as a landowner in the town of Assisi. This suggests that the Colecchi family had already established itself as a prominent presence in the area during that time.
In the 14th century, the Colecchi name appeared in several chronicles and manuscripts from the city of Perugia, located in the Umbria region. These records often mentioned members of the Colecchi family in positions of authority, suggesting their notable status within the local community.
One notable figure bearing the Colecchi surname was Ser Jacopo Colecchi, who lived in the late 15th century. He was a renowned scholar and humanist, known for his contributions to the study of classical literature and philosophy. Another influential Colecchi was Baldassarre Colecchi, a 16th-century architect who designed several notable buildings in the city of Perugia.
During the Renaissance period, the Colecchi family continued to play a significant role in the cultural and political life of central Italy. Francesco Colecchi, born in 1527, was a celebrated poet and playwright whose works were highly regarded in literary circles of the time.
In the 18th century, a branch of the Colecchi family migrated to the southern region of Calabria, where they established themselves as landowners and merchants. One prominent member of this branch was Giuseppe Colecchi, born in 1745, who served as a magistrate and local administrator.
Throughout their history, the Colecchi name has been associated with various professions and positions of influence, including artists, scholars, clergy members, and government officials. While the exact origin of the surname remains uncertain, its longevity and prevalence across different regions of Italy attest to its enduring legacy.
Demographics
Among Census respondents with the surname Colecchi, the largest self-reported group is White at 100.0%.
The bar chart below shows how Colecchi 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 Colecchi surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
