Origin
The surname Marcellus has its origins in ancient Rome, tracing back to the Gens Claudia, a patrician family that played a prominent role in Roman history. The name itself is derived from the Roman praenomen "Marcus," a common name in that era.
The earliest recorded instance of the name Marcellus can be found in the 3rd century BC, when a member of the Claudian family, Marcus Claudius Marcellus, achieved fame as a Roman consul and military commander during the Second Punic War. He was known for his victories against the Carthaginian forces led by Hannibal.
In the Middle Ages, the name Marcellus appeared in various medieval records and manuscripts across Europe, particularly in regions influenced by Roman culture and civilization. One notable example is its inclusion in the Domesday Book, a survey commissioned by William the Conqueror in 1086, which recorded landholders in England.
Over the centuries, the name Marcellus has been associated with several notable individuals. One of the most famous was the Roman emperor Marcus Aurelius Claudius Marcellus Theodosius (347-395 AD), also known as Theodosius I, who played a pivotal role in establishing Christianity as the official religion of the Roman Empire.
Another prominent figure was Marcellus II (1501-1555), an Italian Renaissance scholar and theologian who briefly served as Pope in 1555 before his untimely death after just 22 days in office.
In more recent times, Marcellus Gilmore Edson (1849-1940), an American chemist and industrialist, is credited with the invention of peanut butter and the establishment of the Edson Corporation, a successful manufacturing company.
The name Marcellus has also been associated with various place names, such as Marcellus, a town in New York, and Marcellus, a village in Michigan, both named after the Roman leader Marcus Claudius Marcellus.
Throughout history, variations and spellings of the name have emerged, including Marcello, Marcellino, and Marcellin, reflecting the linguistic and cultural influences of different regions.
Demographics
Among Census respondents with the surname Marcellus, the largest self-reported group is Black at 50.6%. The next largest groups are White (43.1%) and Two or More Races (3.0%).
The bar chart below shows how Marcellus 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 Marcellus surname at the time of the 2020 Census, not any inherent property of the name itself.

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. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
