Origin
The surname Loprinzi has its origins in Italy, specifically in the regions of Sicily and Calabria. It is believed to have emerged during the late medieval period, around the 13th or 14th century. The name is derived from the Italian word "principe," meaning "prince," with the prefix "lo" indicating "the." This suggests that the name may have initially been a descriptive nickname or a reference to someone who held a position of authority or nobility.
One of the earliest recorded instances of the name can be found in a document from the 15th century, where a certain Gaspare Loprinzi is mentioned as a landowner in the town of Palermo, Sicily. Records also indicate that a family bearing the surname Loprinzi resided in the town of Reggio Calabria, located in southern Italy, during the 16th century.
In the 17th century, the name appears in various church records and historical documents related to the regions of Sicily and Calabria. For instance, a nobleman named Girolamo Loprinzi is mentioned in a manuscript from 1687, describing his involvement in the construction of a local chapel in the town of Messina, Sicily.
The 18th century saw the emergence of several notable individuals with the surname Loprinzi. One such figure was Giuseppe Loprinzi, a renowned painter from Palermo who lived from 1701 to 1776. His works, primarily religious paintings and portraits, can be found in various churches and museums throughout Sicily.
Another prominent figure was Antonio Loprinzi, a scholar and philosopher born in Reggio Calabria in 1745. He authored several treatises on ethics and moral philosophy and was a respected figure in academic circles during his time.
In the 19th century, the name Loprinzi continued to be associated with various professions and fields. One notable individual was Vincenzo Loprinzi, a physician and medical researcher from Messina, Sicily, who lived from 1823 to 1897. He made significant contributions to the study of infectious diseases and public health in the region.
As the centuries passed, the surname Loprinzi spread beyond its Italian roots, with families bearing this name settling in other parts of Europe and eventually immigrating to various parts of the world, including North and South America.
Demographics

The bar chart below shows how Loprinzi bearers described their own race and ethnicity on the 2020 Census form. 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 Loprinzi surname at the time of the 2020 Census, not any inherent property of the name itself.
