Origin
Meaning and origin of Giancursio
The surname GIANCURSIO originated in Italy, likely during the 12th or 13th century. It is derived from the combination of the Italian given names "Gian" and "Cursio", which were popular at the time. The name Gian is a shortened form of Giovanni, which is the Italian equivalent of John, while Cursio is a variant of the Latin name Cursius.
GIANCURSIO is believed to have first appeared in historical records in the regions of Campania and Basilicata in southern Italy. These areas were known for their rich agricultural lands and thriving trade routes, which may have contributed to the early adoption of the surname.
One of the earliest recorded instances of the name GIANCURSIO can be found in the Codex Diplomaticus Cavensis, a collection of medieval documents from the Benedictine abbey of Cava dei Tirreni in Campania. This codex, which dates back to the 11th century, contains several references to individuals bearing the surname GIANCURSIO.
In the 14th century, a notable figure named Gian Cursio di Napoli emerged as a prominent merchant and landowner in the city of Naples. His descendants continued to use the surname GIANCURSIO, and some of them achieved notable positions in the local government and church.
Another historical figure of note is Cursio Giancursio, a 15th-century philosopher and scholar from the town of Amalfi. He is known for his work on the interpretation of Aristotelian texts and his contributions to the intellectual circles of Renaissance Italy.
During the 16th century, a branch of the GIANCURSIO family settled in the town of Potenza in Basilicata. This lineage produced several notable individuals, including Giancursio di Potenza, a respected lawyer and judge who served in the local courts.
In the 17th century, a member of the GIANCURSIO family, Giovanni Battista Giancursio, gained recognition as a skilled architect and engineer. He was responsible for designing and constructing several churches and public buildings in the city of Naples.
Throughout the centuries, the GIANCURSIO surname has been recorded in various forms, including Giancursio, Gian Cursio, and Jancursio, reflecting the regional variations and evolution of the Italian language.

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