Origin
Meaning and origin of Demartino
The surname DeMartino has its origins in Italy, emerging during the Middle Ages. It is believed to have been derived from the Italian word "martino," which means "hammer" or "smith." This connection suggests that the earliest bearers of this surname may have been involved in metalworking or blacksmithing trades.
The DeMartino name can be traced back to the central and southern regions of Italy, particularly in areas like Campania, Lazio, and Sicily. Historical records indicate that the name was present in these regions as early as the 13th century, with variations in spelling such as De Martino, Di Martino, and Martino.
One of the earliest documented references to the DeMartino name can be found in the "Codice Diplomatico Barese," a collection of historical documents from the city of Bari, dating back to the 11th century. This manuscript includes mentions of individuals with the surname Martino, which likely served as the precursor to the modern DeMartino form.
In the 14th century, the DeMartino name appeared in various records and documents from the Kingdom of Naples, indicating the presence of families bearing this surname in the southern regions of Italy during that time period. Notable individuals from this era include Giovanni DeMartino, a merchant and landowner from Salerno (born around 1320), and Nicola DeMartino, a renowned architect from Naples (active in the late 1300s).
As the name spread throughout Italy, it also became associated with certain place names. For instance, the town of Martino in the province of Treviso, located in the Veneto region, may have contributed to the formation of the DeMartino surname in that area.
Throughout history, several notable figures have borne the DeMartino surname:
1. Guglielmo DeMartino (1589-1653), an Italian painter and sculptor from Naples, known for his religious artworks.
2. Giacomo DeMartino (1701-1779), a prominent Italian jurist and legal scholar from Palermo, Sicily.
3. Maria DeMartino (1825-1891), an Italian opera singer and soprano, who performed throughout Europe in the mid-19th century.
4. Ernesto DeMartino (1908-1965), an Italian philosopher and sociologist, known for his works on existentialism and Marxist theory.
5. Dominick DeMartino (1925-2010), an American businessman and philanthropist, who co-founded the DeMartino Family Foundation in New York.
While the DeMartino surname has endured for centuries, its origins and historical significance remain rooted in the metalworking and artisan traditions of medieval Italy, reflecting the rich cultural heritage of the Italian peninsula.

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

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.
