Origin
Meaning and origin of Dominicis
The surname DOMINICIS is of Italian origin, with roots dating back to the Middle Ages. It is derived from the Latin phrase "de Dominicis," which translates to "of the Lord" or "belonging to the Lord." This suggests that the name may have been initially bestowed upon individuals or families who had close ties to the Church or religious orders.
The DOMINICIS surname is believed to have originated in the regions of Campania and Lazio, in central and southern Italy. It was particularly prevalent in areas around Rome and Naples, where the influence of the Catholic Church was strong. Some of the earliest documented instances of the name can be traced back to medieval records and manuscripts from these regions.
One notable example is the mention of a Petrus de Dominicis in a Vatican document from the 13th century. This individual was likely a member of the clergy or a religious official associated with the Papacy during that time period.
In the 14th century, a prominent figure named Giovanni di Dominicis was a respected philosopher and theologian from Naples. He is known for his writings on metaphysics and his contributions to the intellectual discourse of the era.
During the Renaissance period, the DOMINICIS surname gained further recognition with the rise of several notable artists and scholars. Among them was Bernardo de Dominicis, a 16th-century Italian painter and architect from Naples, who was renowned for his frescoes in churches and public buildings.
Another illustrious bearer of the DOMINICIS name was Giacomo di Dominicis, a 17th-century scholar and philosopher from Rome. His works on ethics and moral philosophy were highly influential during the Enlightenment period.
Throughout the centuries, the DOMINICIS surname has been associated with various place names and locales in Italy. For instance, the town of Dominicis in the province of Benevento, Campania, may have derived its name from the presence of families bearing this surname in the area.
It is worth noting that the spelling of the surname has undergone slight variations over time, with alternative forms such as De Dominicis, Dominici, and Dominici di being documented in historical records. However, the core meaning and significance of the name have remained consistent, reflecting its connection to the Dominican religious order and the veneration of the Lord.

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