Origin
Meaning and origin of Ignelzi
The surname Ignelzi originates from Italy, specifically the region of Emilia-Romagna. It is believed to have emerged around the 13th century. The name is derived from the Italian word "ignelzo," which means a small hearth or fireplace.
One of the earliest recorded instances of the name Ignelzi appears in a document from the city of Modena, dated 1287. The record mentions a certain "Giovanni Ignelzi," who was a blacksmith by trade. This suggests that the name may have initially been an occupational surname, given to those who worked with fire and forges.
Another historical reference to the Ignelzi name can be found in a manuscript from the town of Carpi, dating back to the late 15th century. The manuscript mentions a family of landowners with the surname Ignelzi, indicating that by that time, the name had gained some prominence in the region.
In the 16th century, a notable figure with the surname Ignelzi was Girolamo Ignelzi (1510-1586), a respected scholar and humanist from Bologna. He authored several works on classical literature and was known for his translations of ancient Greek texts.
During the 17th century, the Ignelzi family established themselves in the city of Ferrara, where they became influential merchants and traders. One prominent member of this branch was Pietro Ignelzi (1625-1697), who was a successful silk merchant and a patron of the arts.
In the 18th century, the name Ignelzi spread to other parts of Italy, including the regions of Tuscany and Lazio. A notable figure from this period was Elisabetta Ignelzi (1745-1823), a renowned opera singer who performed in many of the major theaters of Europe.
Throughout the 19th century, several members of the Ignelzi family made their mark in various fields. These include Francesco Ignelzi (1810-1881), a celebrated painter from Milan, and Giulio Ignelzi (1865-1928), a renowned architect who designed several notable buildings in Rome.

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