Origin
Meaning and origin of Mascis
The surname MASCIS originates from Italy, with its roots dating back to the 13th century. It is believed to have derived from the Italian word "maschio," which means "male" or "masculine." This name was likely given to families with a strong patriarchal lineage or those known for their masculine traits.
One of the earliest recorded instances of the MASCIS surname can be found in the archives of the city of Florence, where a certain Guido MASCIS was mentioned in a document from 1278. This suggests that the name was already established in the region during that time period.
In the 14th century, the name MASCIS appeared in several historical records in the northern Italian cities of Milan and Verona. During this era, the spelling variations included "Maschis" and "Maschi," reflecting the evolution of the Italian language over time.
An noteworthy figure bearing this surname was Bartolomeo MASCIS, a renowned painter from Verona who lived between 1375 and 1449. His works can be found in various churches and galleries across northern Italy, and he is considered a significant contributor to the Renaissance art movement in the region.
The MASCIS surname also has ties to the town of Mascis, located in the province of Perugia, Umbria. It is believed that some families adopted the name as a reference to their place of origin or residence in this town during the medieval period.
In the 16th century, a branch of the MASCIS family migrated to the Spanish-controlled region of Naples, where they established themselves as prominent landowners and merchants. One notable member was Vincenzo MASCIS (1522-1598), who served as a diplomat and advisor to the Spanish viceroy of Naples.
Throughout the centuries, the MASCIS surname has spread across various regions of Italy and beyond, with notable individuals bearing this name. Among them are Antonio MASCIS (1689-1756), a celebrated architect from Rome; Girolamo MASCIS (1814-1892), a philosopher and theologian from Turin; and Carlotta MASCIS (1867-1944), a pioneering feminist and activist from Milan.
While the MASCIS surname may not be among the most common in Italy today, it carries a rich historical legacy, reflecting the country's diverse cultural heritage and the contributions of individuals who bore this name throughout the centuries.

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.

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.

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