Origin
Meaning and origin of Curbello
The surname Curbello originates from Italy and can be traced back to the 16th century. It is believed to have derived from the Latin word "curvus," meaning "curved" or "bent," possibly referring to a physical characteristic or occupation of the original bearer.
Curbello is predominantly found in the regions of Piedmont and Liguria in northern Italy, suggesting that the name may have roots in these areas. Historical records show variations in spelling, such as Curbello, Curbel, and Curbellus, which were common during the medieval period.
One of the earliest recorded instances of the name Curbello can be found in the archives of the city of Genoa, where a document from 1547 mentions a merchant named Giovanni Curbello. This document provides valuable insight into the presence of the name in the maritime trade hub of Genoa during the Renaissance era.
In the 17th century, the name appears in several genealogical records from the town of Albenga in the province of Savona, Liguria. Notably, a Pietro Curbello, born in 1623, is listed as a prominent landowner and member of the local nobility.
During the 18th century, the Curbello surname gained recognition through the achievements of Antonio Curbello (1720-1805), a renowned architect and urban planner from Turin. His masterpiece, the Church of San Francesco da Paola in Turin, is a testament to his skills and continues to be admired for its Baroque architecture.
Another notable figure with the Curbello surname was Giuseppe Curbello (1835-1892), a Italian painter and sculptor from Genoa. His works, which celebrated the beauty of the Italian landscape and captured the essence of daily life, were highly regarded during his lifetime and can be found in various museums and private collections.
In the 20th century, Emilio Curbello (1901-1978), a Ligurian writer and journalist, gained prominence for his contributions to the literary scene. His novels and short stories, often set in the coastal towns of his native region, provided a vivid portrayal of the local culture and traditions.
While the Curbello surname has its roots in Italy, it has since spread to other parts of the world, including South America, where it can be found in countries like Argentina and Uruguay, likely due to Italian immigration in the late 19th and early 20th centuries.

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.
