Origin
Meaning and origin of Allegretti
The surname Allegretti has its origins in Italy, with records tracing it back to the medieval period, around the 12th century. The name derives from the Italian word "allegro," which means "joyful" or "cheerful," possibly suggesting that the first bearers of this name had a lively and spirited personality.
One of the earliest known references to the Allegretti name can be found in historical documents from the city of Siena, Tuscany. The name appears in records dating back to the 13th century, indicating that the family had established roots in this region during that time.
In the 14th century, the Allegretti family gained prominence in the city of Fabriano, located in the Marche region of central Italy. Several members of the family were involved in the production of high-quality paper, which was a significant industry in Fabriano during that era. One notable individual from this period was Francesco Allegretti (c. 1340-1410), a respected papermaker and merchant.
During the Renaissance period, the Allegretti name was associated with the arts and literature. Giovanni Allegretti (1450-1520), a poet and humanist scholar, was born in Siena and gained recognition for his literary works, including a collection of poems titled "Rime."
In the 16th century, the Allegretti family had branches in various parts of Italy, including Rome, where they were involved in ecclesiastical affairs. Girolamo Allegretti (1570-1638), a Roman Catholic priest, served as a canon of St. Peter's Basilica and was known for his theological writings.
Another notable figure was Allegretto Allegretti (1485-1549), a Renaissance architect and engineer from Siena. He was responsible for designing several important buildings in his hometown, including the Loggia del Papa and the Rocca Salimbeni fortress.
As the Allegretti family continued to spread across Italy, they also established themselves in other regions, such as the Veneto and Lombardy. By the 17th and 18th centuries, the name could be found in various parts of the Italian peninsula, with individuals from different branches of the family contributing to various fields, including art, literature, and religious orders.

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