Origin
Meaning and origin of Colarelli
The surname Colarelli has its origins in Italy, specifically in the region of Lazio. It is believed to have emerged during the medieval period, likely between the 11th and 13th centuries. The name is derived from the Italian word "colare," which means "to strain" or "to filter," suggesting a possible occupation or trade association for those who bore this surname initially.
One of the earliest recorded instances of the name Colarelli can be found in a document from the late 13th century, where a certain Giacomo Colarelli is mentioned as a resident of the town of Tivoli, near Rome. This region was known for its wine production, and it is possible that the Colarelli family was involved in the winemaking process, perhaps straining or filtering the wine.
In the 15th century, there are records of a Colarelli family residing in the town of Viterbo, located in the northern part of Lazio. This branch of the family may have been involved in agricultural activities, as Viterbo was known for its fertile lands and agricultural production.
One notable individual bearing the Colarelli surname was Giovanni Colarelli, a 16th-century painter from Rome. He was known for his religious artworks, including frescoes in various churches in and around Rome. His birth and death dates are uncertain, but he is believed to have been active between 1550 and 1580.
Another significant figure was Francesco Colarelli, a 17th-century architect and engineer from Viterbo. He was responsible for the design and construction of several important buildings in Rome, including the Church of Sant'Andrea al Quirinale. Francesco Colarelli lived from approximately 1620 to 1695.
In the 18th century, a Colarelli family from the town of Frosinone, located in the southern part of Lazio, gained prominence. One member, Antonio Colarelli (1708-1776), was a renowned scholar and philosopher who taught at the University of Rome.
During the 19th century, the Colarelli name became more widely dispersed throughout Italy, with families settling in various regions, including Tuscany, Umbria, and Campania. One notable figure from this period was Giuseppe Colarelli (1829-1901), a politician and lawyer from Naples who served as a member of the Italian Parliament.
It is important to note that while this report provides an overview of the Colarelli surname's history and some prominent individuals who bore this name, the genealogical records and historical accounts from earlier periods may be incomplete or subject to varying interpretations.

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