Origin
Meaning and origin of Dimaria
The surname DIMARIA has its origins in Italy, tracing back to the late medieval period around the 14th-15th centuries. It is believed to have originated from the Italian regions of Campania and Lazio, where the name may have derived from the Italian phrase "di Maria," meaning "of Mary." This could suggest a connection to veneration of the Virgin Mary or association with a specific location dedicated to her.
One of the earliest recorded instances of the surname DIMARIA can be found in the historical records of Naples, where a family bearing this name held notable positions in the city's governance during the 15th century. These records mention individuals such as Giacomo DIMARIA, a prominent merchant and magistrate who lived between 1420 and 1487.
In the 16th century, the DIMARIA name appears in various documents from the Papal States, particularly in the area around Rome. One notable figure was Giovanni DIMARIA, a Catholic priest and scholar who authored several theological texts between 1510 and 1578.
The surname DIMARIA also has a presence in the artistic realm, with a renowned painter from the Baroque period bearing this name. Francesco DIMARIA, born in Naples in 1623 and died in 1703, was renowned for his religious paintings and frescoes adorning churches throughout Italy.
During the 18th century, the DIMARIA name gained prominence in the literary world with the poet and playwright Antonio DIMARIA, who lived from 1720 to 1792 and hailed from the town of Bari in southern Italy. His works often explored themes of love and nature, and he was celebrated for his mastery of the Italian language.
In the 19th century, the DIMARIA surname can be found in various historical records from the regions of Calabria and Sicily. One notable figure was Giuseppe DIMARIA, a revolutionary leader who participated in the Risorgimento movement for Italian unification, born in Reggio Calabria in 1818 and died in 1892.

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 Dimaria 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.
