Origin
Meaning and origin of Genuario
The surname Genuario originated in Italy, specifically in the region of Campania during the Middle Ages. It is believed to be derived from the Latin word "genuarius," which means "of or relating to January." This suggests that the name may have been initially given as a nickname to someone born or working in the month of January.
One of the earliest recorded instances of the surname Genuario can be found in a 13th-century document from Naples, where a man named Matteo Genuario was listed as a landowner. This indicates that the name had already been established in the area by that time.
In the 14th century, the Genuario family gained prominence in the town of Capaccio, located in the province of Salerno. Several members of the family held influential positions in the local government and church during this period.
The name Genuario also appears in various historical records from the 15th and 16th centuries, including tax records and legal documents from the Kingdom of Naples. One notable individual was Giulio Genuario, a renowned scholar and philosopher who lived from 1490 to 1567.
During the Renaissance, the Genuario family produced several notable artists and architects. Tommaso Genuario (1520-1592) was a renowned painter whose works can still be found in churches and galleries throughout Italy.
In the 18th century, a branch of the Genuario family settled in the island of Sicily, where they established themselves as successful merchants and landowners. One of the most prominent members of this branch was Giuseppe Genuario (1735-1810), who served as a high-ranking official in the Sicilian government.
Throughout the centuries, the surname Genuario has been associated with various professions, including lawyers, doctors, and academics. In the 19th century, Carlo Genuario (1812-1888) was a respected jurist and legal scholar who made significant contributions to the Italian legal system.
In more recent times, the name Genuario has gained recognition in the field of literature. Mario Genuario (1920-1998) was a celebrated Italian author and poet, known for his works that explored themes of love, loss, and the human condition.
While the surname Genuario is not as common today as it once was, it remains a part of Italy's rich cultural heritage, with its roots tracing back to the Middle Ages and the Latin 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 Genuario surname at the time of the 2020 Census, not any inherent property of the name itself.

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