Meaning and origin of Randazzo
The surname Randazzo has its origins in Italy, specifically in Sicily. It is believed to have emerged during the medieval period, around the 11th or 12th century. The name is derived from the Sicilian town of Randazzo, located in the province of Catania.
Randazzo, the town, was originally known as "Randacium" or "Randatium" during the Roman era. It is thought that the name may have stemmed from the Greek word "rhantos," meaning "sprinkled" or "scattered," possibly referring to the town's scattered or dispersed settlements.
One of the earliest recorded mentions of the surname Randazzo can be found in the "Codice Diplomatico dei Re Aragonesi di Sicilia," a collection of diplomatic documents from the Aragonese rulers of Sicily, dating back to the 13th century. This suggests that the surname was already in use during that time period.

During the 18th century, Francesco Randazzo, a Sicilian poet and writer, gained recognition for his literary works. He was born in Randazzo in 1720 and is known for his poetic compositions and contributions to Sicilian literature.
In the 19th century, Giuseppe Randazzo, a Sicilian patriot and revolutionary, played a significant role in the struggle for Italian unification and independence. He participated in the Sicilian uprising against the Bourbon monarchy in 1848 and later joined the forces of Giuseppe Garibaldi in the expedition to unify Italy.
Another notable figure with the surname Randazzo was Vincenzo Randazzo, a Sicilian painter and artist who lived in the late 19th and early 20th centuries. He was known for his realistic and vivid depictions of Sicilian landscapes and scenes from everyday life.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
