Origin
Meaning and origin of Dimartino
The surname DiMartino originates from Italy and dates back to the medieval period. It is believed to have derived from the Italian personal name Martino, which was the Italian form of the Latin name Martinus, meaning "of Mars" or "dedicated to Mars," the Roman god of war.
The earliest recorded instances of the surname DiMartino can be traced back to the 13th century in Sicily and other parts of southern Italy. It is believed that the prefix "Di" was added to the name to indicate a patronymic surname, meaning "son of Martino."
In the 14th century, records show that the surname DiMartino appeared in various historical documents and manuscripts, including tax records and property deeds in the region of Calabria, located in the southern part of the Italian peninsula.
One of the earliest notable individuals with the surname DiMartino was Giovanni DiMartino, a 15th-century Sicilian nobleman and landowner who played a prominent role in the local politics of the city of Palermo. Another early bearer of the name was Pietro DiMartino, a renowned painter and fresco artist who lived in Naples during the late 16th century.
The surname DiMartino has also been associated with several place names in Italy, such as the town of Martino in the province of Campobasso and the village of DiMartino in the province of Messina, Sicily. These place names likely originated from individuals with the surname DiMartino who had settled in those areas.
Among the notable individuals with the surname DiMartino throughout history are:
1. Antonio DiMartino (1539-1619), a Sicilian architect and engineer who designed several important buildings and fortifications in Palermo.
2. Domenico DiMartino (1671-1745), an Italian composer and musician who served as the maestro di cappella (chapel master) at the Basilica of San Marco in Venice.
3. Giuseppe DiMartino (1779-1859), an Italian painter and sculptor who was known for his religious works and portraits.
4. Maria DiMartino (1864-1932), an Italian-American educator and advocate for women's rights, who played a significant role in establishing Italian language programs in New York City schools.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Dimartino (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. 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.
