Origin
Meaning and origin of Settimi
The surname Settimi originates from Italy, specifically the region of Tuscany. It can be traced back to the late medieval period, around the 13th century. The name Settimi is derived from the Italian word "settimo," meaning "seventh," suggesting a possible connection to an ancestor who was the seventh child or held a seventh position within a hierarchy or organization.
One of the earliest recorded instances of the name Settimi can be found in the historical documents of the city of Florence. In the 14th century, a wealthy merchant family bearing the name Settimi played a prominent role in the city's economic and political affairs. Their influence extended to various sectors, including banking, trade, and civic governance.
In the 15th century, a notable figure with the surname Settimi was Gherardo Settimi (1390-1459), a renowned humanist scholar and diplomat. He served as the ambassador of the Florentine Republic to various European courts and was highly respected for his intellectual contributions and diplomatic skills.
Another significant individual bearing the name Settimi was Raffaello Settimi (1600-1680), a celebrated architect who played a pivotal role in the architectural renaissance of Rome during the 17th century. His notable works include the design of the Church of Santi Apostoli and the restoration of the Palazzo del Quirinale, which later became the official residence of the Italian President.
In the 19th century, the Settimi name gained further recognition with the birth of Giuseppe Settimi (1823-1891), a renowned Italian mathematician and physicist. He made significant contributions to the field of mathematical analysis and served as a professor at the University of Rome, where he influenced generations of scholars.
Throughout history, the Settimi surname has also been associated with various locations in Tuscany, such as the town of Settimo Fiorentino, which likely derives its name from the Latin phrase "ad septimum lapidem," meaning "at the seventh mile stone" from Florence. This connection suggests that the name may have originated from a place name or vice versa.
While the name Settimi is predominantly Italian, it has also been adopted by families in other parts of Europe and beyond, possibly through migration or intermarriage. However, the historical roots of the surname can be traced back to the rich cultural heritage of Tuscany and the prominent families who bore this name throughout the centuries.

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