Origin
Meaning and origin of Lumbatis
The surname LUMBATIS is believed to have originated in Italy during the medieval period. It is derived from the Latin word "lumbatus," which means "one with a loin problem or back pain." The name likely referred to someone who had a physical impairment or injury related to their lower back or hips.
In the early 13th century, records show a family with the surname LUMBATIS residing in the region of Tuscany. The name appears in several documents from the city of Florence, indicating that the family may have been among the influential merchant class during the Renaissance era.
One of the earliest known bearers of the LUMBATIS name was Guido LUMBATIS, a wealthy wool trader who lived in Florence between 1265 and 1328. He was involved in the city's lucrative textile industry and is mentioned in several contracts and guild records from that time.
Another notable LUMBATIS was Beatrice LUMBATIS, a nun who lived in the convent of Santa Maria Novella in Florence during the late 14th century. She is known for her illuminated manuscripts and intricate calligraphy, which can be found in the convent's library today.
In the 16th century, the LUMBATIS family expanded to other regions of Italy, including Lombardy and Veneto. Marco LUMBATIS, born in 1512 in Venice, was a renowned architect who designed several churches and palaces in the city, including the Church of San Zaccaria.
During the 18th century, a branch of the LUMBATIS family settled in the Kingdom of Naples. Antonio LUMBATIS, born in 1732, was a prominent lawyer and political advisor to the Bourbon kings of Naples. His son, Giuseppe LUMBATIS (1768-1842), followed in his footsteps and served as a judge in the Neapolitan court system.
While the LUMBATIS surname is not as common today, it has left a lasting legacy in Italian history, particularly in the fields of commerce, arts, and law. The name's unique origin and association with physical ailments have made it a distinctive and memorable part of Italian onomastics.

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