Origin
The surname Martello originated in Italy during the medieval period, derived from the Italian word "martello," meaning "hammer." This name is believed to have been an occupational surname, referring to someone who worked as a blacksmith or metalworker, using a hammer as their primary tool.
The earliest known record of the Martello surname dates back to the 13th century in the region of Tuscany, where it was commonly found in cities like Florence and Siena. It's possible that the name also has roots in the Latin word "martellus," which has a similar meaning.
During the Renaissance era, the Martello family gained prominence in various Italian cities. One notable figure was Giovanni Martello, a prominent architect from Florence who lived in the 15th century and contributed to the design of several buildings in the city.
In the 16th century, the Martello surname made its way to other parts of Europe, particularly England and France, where it was anglicized and adapted to local spellings. One notable English bearer of the name was Peter Martello, a merchant and explorer who was active in the 17th century.
The Martello surname also gained recognition in the 18th century when the Martello tower, a type of defensive fortification, was named after its inventor, the Italian engineer Pietro Martello (1663-1720). These towers were built along the coasts of Britain and other countries to defend against potential invasions.
Another notable figure with the Martello surname was Pier Giacomo Martello (1665-1727), an Italian poet and satirist known for his contributions to the development of Italian literature during the Baroque period.
In the 19th century, the Martello name spread further across Europe and beyond, with bearers of the surname found in various countries, including Spain, Germany, and even as far as Australia and the United States.
Throughout history, the Martello surname has been associated with various professions and occupations, including metalworking, architecture, literature, and military engineering, reflecting the diverse backgrounds and contributions of those who have carried this name.
Demographics
Among Census respondents with the surname Martello, the largest self-reported group is White at 89.7%. The next largest groups are Hispanic (6.9%) and Two or More Races (2.0%).
The bar chart below shows how Martello 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 Martello surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.

For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
