Origin
Meaning and origin of Dicorcia
The surname DiCorcia originated in Italy, likely during the late medieval period or the Renaissance era. It is believed to be derived from the Italian phrase "di Corcia," which translates to "from Corcia." Corcia was a place name, possibly referring to a town or region in Italy where the family originated.
The earliest known records of the DiCorcia surname can be traced back to the 14th or 15th century in various Italian documents and manuscripts. One notable example is a reference to a Giacomo DiCorcia in a deed from the city of Florence, dated 1412. This suggests that the family may have roots in the Tuscan region of Italy.
Over the centuries, the name has undergone slight variations in spelling, such as Dicorcia, De Corcia, or Di Corcia. These variations were likely due to regional dialects, scribal errors, or personal preferences.
Several individuals with the surname DiCorcia have achieved prominence throughout history. One notable figure was Giovanni DiCorcia (1560-1629), a renowned Italian painter and architect who worked during the late Renaissance and early Baroque periods. His most famous works include frescoes in churches throughout Rome and the design of the Chiesa di San Giorgio al Velabro.
Another prominent individual was Stefano DiCorcia (1685-1752), an Italian composer and violinist who served as the court musician for several Italian noble families. His compositions, primarily instrumental works for violin and chamber ensembles, were highly regarded during his lifetime.
In the 19th century, there was Lorenzo DiCorcia (1812-1891), an Italian statesman and politician who served as a member of the Sardinian Parliament and later the Italian Chamber of Deputies after the unification of Italy.
During the early 20th century, Antonio DiCorcia (1901-1978) was a respected Italian-American artist known for his paintings and murals depicting scenes from Italian-American life in New York City. His works can be found in several public buildings and galleries throughout the city.
More recently, Philip-Lorca DiCorcia (born 1951) is a contemporary American photographer renowned for his staged and candid street photography. His work has been exhibited in major museums and galleries worldwide, and he has received numerous awards and accolades for his contributions to the art form.
While the DiCorcia surname is most closely associated with Italian heritage, it has spread to other parts of the world through immigration and cultural exchange over the centuries.

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.
