The surname Achilli is of Italian origin, originating from the northern region of the country.

The name Achilles itself is thought to have come from the Greek word "achos," meaning pain or distress.
In ancient times, the name Achilli was found in various Italian regions, particularly in the areas around modern-day Milan and Venice. Records from the 12th century mention individuals with this surname in the cities of Verona and Padua.
One of the earliest documented references to the name Achilli can be found in the Codice Diplomatico Veronese, a collection of medieval documents from the city of Verona, dating back to the 13th century.

During the Renaissance period, the Achilli family gained prominence in the city of Florence. In the 15th century, a notable member of the family was Giovanni Achilli, a renowned painter and sculptor who contributed to the decoration of several churches and palaces in the city.
Another influential figure with this surname was Giacomo Achilli, a controversial Italian theologian and former Catholic priest who lived in the 19th century (1803-1900). He was a prominent figure in the Oxford Movement, a movement within the Church of England that sought to restore some Catholic traditions.
In the realm of literature, one notable bearer of the Achilli surname was Vittorio Achilli, an Italian writer and journalist who lived in the late 19th and early 20th centuries (1855-1929). He was known for his novels and short stories that explored themes of love, society, and the human condition.
Another figure of historical significance was Antonio Achilli, an Italian composer and violinist who lived in the 18th century (1727-1805). He was active in the Neapolitan School of opera composers and wrote several operas and instrumental works that were popular during his time.

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.

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