Origin
Meaning and origin of Micieli
The surname MICIELI has its origins in Italy, with records dating back to the 14th century. It is believed to have derived from the Italian word "miciel," which means "to harvest" or "to reap." The name was likely given to those who worked as harvesters or reapers of crops, indicating their occupation.
One of the earliest known references to the name MICIELI can be found in a document from the city of Siena, dated 1387. The document mentions a family with the surname MICIELI residing in the area. This suggests that the name was already in use during that time period.
In the 15th century, a notable figure named Giovanni MICIELI (1430-1499) was a prominent merchant and banker in the city of Florence. His success in business and his involvement in local politics made him a well-known figure in the region.
Another historical figure with the surname MICIELI was Bartolomeo MICIELI (1570-1638), a Franciscan friar and scholar from the town of Montefalco. He was known for his writings on theology and philosophy, which were widely read and studied in his time.
The name MICIELI can also be found in records from the region of Calabria in southern Italy. In the 16th century, a family with the surname MICIELI was documented as residing in the town of Cosenza. The name may have been derived from the local dialect, which often had variations in spelling and pronunciation.
In the 18th century, Antonio MICIELI (1710-1783) was a prominent architect and engineer from the city of Naples. He was responsible for the design and construction of several notable buildings and infrastructure projects in the region, leaving a lasting impact on the city's architecture.
As the surname MICIELI spread across Italy, it also found its way into other regions and countries. In the 19th century, records show a family with the surname MICIELI residing in the city of Marseille, France, suggesting that they may have migrated from Italy at some point.
Throughout its history, the surname MICIELI has been associated with various occupations, from agriculture and commerce to scholarly pursuits and skilled trades. While the name may have evolved over time, its connection to the Italian roots and the concept of "harvesting" or "reaping" remains a notable aspect of its etymology.

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