Origin
The surname Niblo is believed to have originated in the British Isles, likely in England or Scotland, during the medieval period. It is thought to be derived from the Old English word "nibbe," which referred to a projecting peak or promontory. This suggests that the name may have initially been used to describe someone who lived near or on a prominent hill or cliff.
One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, which was a comprehensive survey of landowners and tenants commissioned by William the Conqueror. In this document, the name appears as "Nibbell," possibly referring to a person or a place.
During the 13th and 14th centuries, variations of the name, such as "Nibley" and "Niblett," began appearing in various historical records, including parish registers and tax rolls. These spellings may have been influenced by the presence of place names like Nibley in Gloucestershire, England, and Niblett in Somerset.
One notable figure from history bearing the Niblo surname was Sir John Niblo, a Scottish merchant and politician who lived in the late 16th century. He served as a member of the Scottish Parliament and was known for his involvement in trade and commerce.
In the 17th century, the name Niblo gained some prominence in Ireland, where it may have been adopted by English or Scottish settlers. One such individual was William Niblo, born in 1714, who was a prominent landowner and businessman in County Antrim.
Another historical figure of note was James Niblo, an American theater manager and entrepreneur born in 1790. He established the famous Niblo's Garden in New York City, which was a popular entertainment venue in the mid-19th century.
Other individuals bearing the Niblo surname include Thomas Niblo (1795-1878), an English actor and playwright, and William Niblo (1810-1878), an American architect who designed several notable buildings in New York City.
Throughout its history, the Niblo surname has remained relatively uncommon, but its origins and variations provide a glimpse into the rich linguistic and cultural heritage of the British Isles and the diverse stories of those who carried this name across generations.
Demographics
Among Census respondents with the surname Niblo, the largest self-reported group is White at 87.0%. The next largest groups are Hispanic (8.1%) and Asian/Pacific Islander (2.4%).
The bar chart below shows how Niblo 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 Niblo 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.
