Origin
Meaning and origin of Esposti
The surname Esposti has its roots in Italy, originating in the 14th century. It is derived from the Italian word "esposto," which means "exposed" or "abandoned." The name likely referred to a child who was left at a foundling hospital or a church door in the early days.
In medieval Italy, foundling hospitals and orphanages were common institutions that took in abandoned or orphaned children. The name Esposti was often given to these children, as they were "exposed" or left in the care of these institutions.
One of the earliest recorded instances of the name Esposti can be found in the records of the Ospedale degli Innocenti, a famous foundling hospital established in Florence in 1419. The hospital's archives contain numerous references to children with the surname Esposti who were taken in and raised by the institution.
During the Renaissance period, the Esposti name appeared in various Italian cities, including Florence, Rome, and Venice. Notable individuals with this surname include Giovanni Battista Esposti (1570-1633), an Italian painter and engraver from Bologna, and Giacomo Esposti (1681-1756), a Bolognese painter known for his religious works.
In the 18th century, the Esposti family gained prominence in the city of Modena, where several members held positions of power and influence. One such figure was Count Giuseppe Esposti (1732-1798), a nobleman and politician who served as the mayor of Modena from 1780 to 1786.
Another notable bearer of the Esposti name was Benedetto Esposti (1781-1860), an Italian poet and playwright from Modena. He is best known for his comedic works, which satirized the social and political climate of his time.
In the 19th century, the Esposti surname spread beyond Italy as families emigrated to other parts of Europe and the Americas. One prominent example is Alfredo Esposti (1867-1943), an Italian-born Argentine architect who designed several iconic buildings in Buenos Aires, including the Palace of Justice and the National Library.
Throughout its history, the surname Esposti has been associated with a diverse range of professionals, from artists and writers to politicians and architects. While its origins may have been humble, the name has endured and gained significance in various parts of the world.

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