Origin
Meaning and origin of Impellizeri
The surname Impellizeri has its roots in Sicily, Italy, dating back to the medieval period. The name is believed to be derived from the Italian word "impellizare," which means "to cover with fur" or "to line with fur." This suggests that the original bearers of this surname may have been involved in the fur trade or textile industry.
One of the earliest recorded instances of the Impellizeri name can be found in the archives of the town of Caltanissetta, Sicily, dating back to the 15th century. The name appears in various spellings, such as "Impellizeri," "Impellizzeri," and "Impellizzari," reflecting the regional variations in pronunciation and spelling.
In the 16th century, a notable figure named Giovanni Impellizeri (1520-1585) was a renowned scholar and humanist from Palermo, Sicily. He wrote several works on philosophy and literature, contributing to the intellectual landscape of the Renaissance period.
During the 17th century, the Impellizeri family gained prominence in the town of Partanna, Sicily. Records show that a certain Vincenzo Impellizeri (1635-1702) was a respected landowner and merchant, playing an influential role in the local community.
In the 18th century, the name Impellizeri appeared in the records of the town of Castelvetrano, Sicily. One of the most prominent figures from this era was Giuseppe Impellizeri (1745-1821), a respected lawyer and judge known for his expertise in civil law.
Another notable individual bearing the Impellizeri name was Gaetano Impellizeri (1810-1888), a prominent politician from Palermo who served as a member of the Sicilian Parliament during the Risorgimento, the movement for Italian unification.
The Impellizeri surname has since spread beyond Sicily to other parts of Italy and even to various parts of the world, carried by emigrants seeking new opportunities. However, its origins can be traced back to the rich history and cultural traditions of Sicily, where the name first emerged and gained significance.

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