Origin
Meaning and origin of Midolo
The surname Midolo is of Italian origin, specifically from the island of Sicily. It is derived from the Latin word "medulla," which means "marrow" or "pith." This suggests that the name may have originally referred to someone who worked with plants or agricultural products.
The earliest recorded instances of the Midolo surname date back to the 13th century in Sicily. In 1271, a document from the town of Palermo mentions a "Nicolaus Midolo" as a landowner. Another early record is found in a 1298 census from Trapani, which lists a "Matteo Midolo" as a resident.
During the Middle Ages, the Midolo family was prominent in several Sicilian towns, particularly in the areas around Palermo and Trapani. They were often involved in agriculture and the production of olive oil and wine.
One notable bearer of the Midolo name was Giacomo Midolo, a 15th-century merchant and banker from Palermo. He was influential in establishing trade connections between Sicily and other Mediterranean regions.
In the 16th century, a branch of the Midolo family settled in the town of Castelvetrano, located in the province of Trapani. This line of the family produced several notable figures, including Francesco Midolo (1540-1618), a renowned jurist and legal scholar.
Another prominent individual with the Midolo surname was Vincenzo Midolo (1678-1742), a Baroque architect from Palermo. He designed several churches and palaces in the city, including the Chiesa di Santa Maria della Catena and the Palazzo Belmonte Riso.
The Midolo name can also be found in historical records from other parts of Italy, such as Naples and Calabria, suggesting that members of the family may have migrated from Sicily over the centuries. However, the name's roots and earliest documented occurrences are firmly rooted in the island of Sicily.

The bar chart below shows how Midolo 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 Midolo 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.
