Origin
Meaning and origin of Carpanzano
The surname Carpanzano originates from Italy, specifically the southern regions of Calabria and Sicily. It likely emerged during the medieval period, between the 11th and 13th centuries. The name is believed to derive from the Italian word "carpane," which refers to a type of oak tree common in the area.
One of the earliest known references to the Carpanzano name appears in a land registry document from the town of Montalto Uffugo in Calabria, dating back to the late 13th century. This record mentions a family with the surname Carpanzano as landowners in the region. Additionally, variations of the name, such as Carpanzani and Carpenzano, can be found in historical records from neighboring towns and villages.
In the 15th century, the name Carpanzano appears in a manuscript titled "Codice Diplomatico Brindisino," which is a collection of documents related to the city of Brindisi in Apulia. This suggests that the name had spread to other parts of southern Italy by that time.
One notable figure with the Carpanzano surname was Girolamo Carpanzano, a Sicilian painter and sculptor who lived from 1589 to 1659. He is known for his works in churches and palaces throughout Sicily, particularly his sculptures and altarpieces featuring religious themes.
Another individual of note was Francesco Carpanzano, a lawyer and politician who served as a member of the Sicilian parliament in the late 18th century. He was born in Palermo in 1742 and played a significant role in the political and legal affairs of the region during his time.
In the 19th century, a wealthy landowner named Giuseppe Carpanzano was mentioned in several historical documents related to the town of Nicastro (now Lamezia Terme) in Calabria. He was known for his extensive agricultural holdings and influence in the local community.
The name Carpanzano can also be traced to certain place names in southern Italy, such as the hamlet of Carpanzano, located near the town of Grisolia in the province of Cosenza, Calabria. This suggests that the surname may have derived from a specific geographic location.
Throughout history, various spellings of the Carpanzano name have been documented, including Carpanzani, Carpenzano, and Carpanzanu, reflecting regional linguistic variations and historical spelling conventions.

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