Origin
Meaning and origin of Giglio
The surname Giglio originated in Italy during the medieval period, with its roots tracing back to the Latin word "lilium," meaning "lily." This floral connection suggests that the name may have initially been associated with individuals involved in the cultivation or trade of lilies, or perhaps used as a descriptive surname for someone residing near a place where these flowers grew abundantly.
One of the earliest recorded mentions of the name Giglio can be found in the historical records of the Florentine Republic, specifically in a document dated 1287, which references a certain "Jacopo del Giglio." This suggests that the name had already established itself in the region by the 13th century.
In the 14th century, the Giglio family gained prominence in the city of Lucca, where they were influential merchants and bankers. Historical records from this era mention several members of the family, including Piero Giglio (1320-1388), who served as a diplomat and ambassador for the Republic of Lucca.
As the name spread throughout Italy, variations in spelling emerged, such as Gigli, Gilli, and Gilio. These variations were often influenced by regional dialects and local pronunciations.
One notable figure bearing the surname Giglio was the Italian sculptor and architect Baccio Bandinelli (1493-1560), whose full name was Bartolomeo Gigli, but who was better known by his nickname "Il Baccio Bandinelli."
In the 16th century, the Giglio family established itself in the Kingdom of Naples, where they held several feudal titles. One prominent member was Girolamo Giglio (1532-1610), a jurist and philosopher who served as a legal advisor to the Spanish viceroys of Naples.
During the Renaissance, the surname Giglio was also associated with the arts, with several painters and architects bearing this name. Among them was the Florentine architect and engineer Giulio Gigli (1572-1635), who designed several notable buildings in Florence.
Throughout the centuries, the Giglio surname has continued to be represented across various fields, including literature, academia, and politics. For instance, Giovanni Giglio (1769-1836) was an Italian poet and translator, while Giuseppe Giglio (1876-1957) was a prominent Italian jurist and politician who served as a minister in the government of Benito Mussolini.

The bar chart below shows how Giglio bearers described their own race and ethnicity on the 2020 Census form. 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 Giglio surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
