Origin
The surname Martorello originated in Italy, specifically in the regions of Sicily and Calabria. It is a locational name derived from the Italian town of Martorella, located in the province of Messina, Sicily. The name likely stems from the Latin word "martulus," meaning "little hammer," which may have referred to a hammer-maker or blacksmith residing in that area.
Martorello can be traced back to the 13th century, with one of the earliest recorded instances being a certain Rinaldo Martorello, mentioned in a document from the town of Roccalumera, near Messina, dated 1287. Another early reference is found in the census records of Palermo in 1324, where a family with the surname Martorello is listed among the city's residents.
In the 15th century, a notable figure bearing this surname was Antonio Martorello, a nobleman and landowner from the town of Mistretta in Sicily. He is mentioned in several local records from the years 1460 to 1478, detailing his land holdings and legal transactions.
During the 16th century, the name Martorello began to spread to other parts of Italy, particularly to the neighboring region of Calabria. One of the earliest recorded instances in Calabria is that of Girolamo Martorello, a merchant from the city of Reggio Calabria, who is mentioned in a trade document from 1527.
In the 17th century, a notable figure with this surname was Domenico Martorello, a Catholic priest and scholar born in Palermo, Sicily, in 1612. He authored several religious texts and served as a professor of theology at the University of Palermo until his death in 1685.
Another prominent individual with this surname was Giuseppe Martorello, a lawyer and politician from Messina, Sicily, who lived from 1738 to 1812. He held various important positions in the local government and was known for his efforts in promoting education and legal reforms in the region.
Throughout history, the surname Martorello has maintained its strong ties to the regions of Sicily and Calabria, with many variations in spelling, such as Marturello, Martorano, and Martorella, emerging over time. Despite its relatively localized origins, the name has been carried by individuals who have made significant contributions in various fields, reflecting the rich cultural heritage of these Italian regions.
Demographics

The bar chart below shows how Martorello bearers described their own race and ethnicity on the 2020 Census form. 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 Martorello surname at the time of the 2020 Census, not any inherent property of the name itself.
