Origin
Meaning and origin of Cascio
The surname Cascio originated in Italy, specifically in the region of Sicily. It is believed to have derived from the Italian word "casco," meaning "helmet," which could suggest an occupation or a nickname for an ancestor who wore a helmet or was involved in military activities.
One of the earliest recorded instances of the name Cascio can be found in a document from the 13th century, referring to a family residing in the town of Catania, Sicily. The name was also mentioned in various local records and manuscripts from the medieval period, indicating its long-standing presence in the region.
During the Renaissance period, the name Cascio gained prominence with several notable individuals bearing this surname. One such figure was Antonio Cascio (1480-1545), a renowned architect from Palermo, Sicily, who is credited with designing several churches and palaces in the city.
Another prominent individual with the surname Cascio was Vincenzo Cascio (1628-1696), a Baroque painter from Messina, Sicily. His works adorned several churches and noble residences throughout the region, showcasing his mastery of the Baroque style.
In the 18th century, the name Cascio was associated with the town of Monreale, near Palermo. Records mention a wealthy landowner named Giuseppe Cascio (1725-1798), who played a significant role in the local economy and politics of the time.
Moving into the 19th century, the name Cascio gained international recognition with the birth of Antonio Cascio (1842-1921), a Sicilian-American sculptor and architect. He emigrated to the United States and contributed to the design of several notable buildings, including the Basilica of St. Patrick's Old Cathedral in New York City.
Furthermore, in the 20th century, the name Cascio was associated with the Italian-American mobster Frank Cascio (1918-1957), a member of the Bonanno crime family in New York City. Despite his notorious reputation, he was also known for his philanthropic efforts within the Italian-American community.

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.

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
