Origin
Meaning and origin of Deluce
The surname DELUCE is of Italian origin, tracing its roots back to the regions of Tuscany and Umbria during the medieval period. It is believed to have evolved from the Latin phrase "de luce," which translates to "of light" or "from the light." This could suggest that the name was initially associated with individuals who lived near a prominent light source, such as a lighthouse or a well-lit area.
One of the earliest recorded instances of the name DELUCE can be found in the Codice Diplomatico Longobardo, a collection of historical documents from the Lombard era in Italy, dating back to the 8th century. This suggests that the name has a long-standing history in the region.
The name DELUCE also appears in several ancient manuscripts and records from the 13th and 14th centuries, indicating its presence in various Italian cities and towns. For example, the Florentine chronicles mention a family by the name of DELUCE residing in the city during the 1300s.
One notable figure bearing the surname DELUCE was Giovanni Battista DELUCE (1614-1681), a renowned Italian painter from the Baroque period. His works adorned several churches and palaces throughout Italy, showcasing his exceptional artistic talent.
Another prominent individual was Pietro DELUCE (1768-1842), a celebrated architect from Tuscany. He was responsible for designing several notable buildings, including the Palazzo Comunale in Arezzo, which remains an architectural landmark to this day.
In the realm of literature, Maria DELUCE (1892-1975) was an acclaimed Italian novelist and poet. Her works explored themes of love, loss, and the human condition, earning her widespread recognition and critical acclaim.
Additionally, the name DELUCE has been linked to various place names and geographical locations in Italy. For instance, the town of Delucca in the province of Rieti is believed to have derived its name from the DELUCE family, who may have held significant influence or ownership in the area during the medieval period.
Over the centuries, the surname DELUCE has also seen variations in spelling, such as DeLuce, DeLucca, and DeLucchi, reflecting regional dialects and linguistic evolutions. However, the essence of its meaning, rooted in the concept of light, has remained a consistent thread throughout its history.

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