Origin
The surname Rolly has its origins in France, with the earliest records dating back to the 12th century. It is believed to have derived from the Old French word "rolle," which means a roll or scroll. This suggests that the name may have originally referred to a person who worked as a scribe or a record keeper.
One of the earliest recorded instances of the name Rolly can be found in the Cartulaire de Beauvais, a manuscript dating from the late 12th century. This document mentions a person named Rolly de Marcellis, who was likely a resident of the town of Marcelli in the Île-de-France region.
During the 13th century, the name Rolly began to spread throughout northern France, particularly in the regions of Normandy and Picardy. It is possible that the name was associated with certain occupations, such as clerks, scribes, or administrators, who were responsible for maintaining records and rolls of parchment.
In the 14th century, the Rolly surname appears in several historical records, including the Burgundian Roll of Arms, a compilation of heraldic emblems from the Duchy of Burgundy. This suggests that by this time, the Rolly family had achieved a certain level of prominence and nobility.
One notable figure bearing the Rolly surname was Jean Rolly, a French composer and organist who lived from 1659 to 1719. He served as the organist at the Chapelle Royale in Paris and composed numerous works for the organ and other instruments.
Another individual of note was Jacques Rolly, a French painter who lived from 1726 to 1783. He was a member of the Académie Royale de Peinture et de Sculpture and is known for his portraits and religious paintings.
In the 19th century, the Rolly surname can be found in various regions of France, including Alsace, Lorraine, and the Loire Valley. One notable bearer of the name was Firmin Rolly, a French architect who lived from 1810 to 1884. He designed several notable buildings in Paris, including the Église Notre-Dame de Clignancourt.
While the surname Rolly is not as common today as it once was, it continues to hold a place in French history and culture, with its roots stretching back to the medieval period and its association with the world of scribes and record-keeping.
Demographics
Among Census respondents with the surname Rolly, the largest self-reported group is White at 59.6%. The next largest groups are Hispanic (14.7%) and Asian/Pacific Islander (13.8%).
The bar chart below shows how Rolly 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 Rolly 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.
