Origin
Meaning and origin of Giello
The surname Giello is of Italian origin and can be traced back to the 14th century. It is believed to have originated from the northern regions of Italy, particularly in the areas around Venice and Padua. The name Giello is thought to be derived from the Italian word "giallo," which means yellow or golden in color.
Some historians suggest that the name Giello may have been initially given as a nickname or descriptive term to individuals who had yellow or golden hair or complexions. It could also have been associated with occupations related to the production or trade of yellow dyes or fabrics.
Historical records indicate that the Giello surname appeared in various documents and manuscripts from the 14th and 15th centuries. One notable example is the mention of a Giovanni Giello in a Venetian trade register from the year 1378, where he was listed as a merchant dealing in silk and spices.
In the 16th century, the Giello name can be found in several records from the towns of Padua and Vicenza. One of the earliest recorded individuals with this surname was Antonio Giello, born in Padua around 1520. He was a renowned scholar and professor of philosophy at the University of Padua.
Another notable figure was Giacomo Giello, born in Venice in 1589. He was a successful merchant and trader who established trade routes between Italy and the Ottoman Empire, dealing in various goods including textiles and spices.
In the 17th century, the Giello surname spread to other parts of Italy, including the regions of Tuscany and Umbria. One prominent individual was Bartolomeo Giello, born in Florence in 1621. He was a skilled architect and was involved in the design and construction of several churches and palaces in Florence and surrounding areas.
During the 18th century, a branch of the Giello family settled in the city of Naples. One of the most notable figures from this period was Giuseppe Giello, born in Naples in 1732. He was a renowned painter and sculptor, known for his religious artworks and portrait commissions from noble families.
In more recent times, the Giello surname has been carried by individuals from various professions and backgrounds. One example is Roberto Giello, an Italian-American author and novelist born in New York City in 1935. His works explored themes of immigration, identity, and the Italian-American experience.

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

Does the Census include every surname?

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