Origin
Meaning and origin of Cassuto
The surname CASSUTO has its origins in Italy, specifically in the regions of Piedmont and Liguria. It is believed to have derived from the Italian word "cassa," meaning "chest" or "box," and was likely an occupational surname given to those who made or dealt with chests or boxes.
The earliest recorded instances of the name CASSUTO date back to the 13th century. In 1289, a document from the city of Genoa mentions a certain "Guglielmo Cassuto," who was involved in a trade dispute. This suggests that the name was already well-established in the region by that time.
During the Middle Ages, the CASSUTO surname appeared in various records and manuscripts across northern Italy. One notable example is a 14th-century text from the city of Savona, which references a "Giovanni Cassuto" who served as a local magistrate.
As the centuries passed, the CASSUTO family spread throughout Italy and beyond. Some notable individuals bearing this surname include:
1. Umberto Cassuto (1883-1951), an Italian-Israeli biblical scholar and Semitic philologist, renowned for his contributions to the study of the Hebrew Bible and the history of the Hebrew language.
2. Moshe David Cassuto (1858-1939), an Italian rabbi and scholar who served as the Chief Rabbi of Florence and wrote extensively on Jewish law and philosophy.
3. Raffaele Cassuto (1835-1912), an Italian painter known for his landscapes and genre scenes, particularly those depicting the rural life of his native Piedmont region.
4. Dino Cassuto (1890-1977), an Italian-American artist and sculptor who emigrated to the United States in the early 20th century and became known for his abstract and modernist works.
5. Vincenzo Cassuto (1806-1873), an Italian politician and jurist who served as a member of the Parliament of the Kingdom of Sardinia and played a role in the unification of Italy.
While the CASSUTO surname has its roots in Italy, it has since spread to other parts of the world, particularly through migration and diaspora communities. However, its origins can be traced back to the occupational and regional ties of its early bearers in northern Italy during the Middle Ages.

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 Cassuto 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.
