Origin
The surname BELLFY has its origins in the northern French region of Normandy, dating back to the early 11th century. It is believed to have derived from the Old French words "belle" and "foy," meaning "beautiful" and "faith," respectively. This combination suggests that the name may have initially been bestowed upon someone known for their physical attractiveness and unwavering loyalty or devotion.
One of the earliest recorded instances of the BELLFY name can be found in the renowned Domesday Book, a comprehensive survey of land and property ownership commissioned by William the Conqueror in 1086. The entry mentions a landowner named Robert Bellfy residing in the village of Bellefontaine, located in the Calvados region of Normandy.
During the 13th century, the BELLFY name began to appear more frequently in various historical documents and records throughout northern France. Notable individuals bearing this surname include Guillaume BELLFY, a successful merchant from Rouen who lived between 1250 and 1312, and Jeanne BELLFY, a noble lady mentioned in the court records of King Louis IX in 1268.
As the centuries passed, the BELLFY name spread beyond the borders of France. In the 16th century, Jacques BELLFY, a French Huguenot born in 1542, fled religious persecution and sought refuge in the Netherlands, where he and his descendants settled and prospered.
Another notable figure was Sir Edward BELLFY, an English courtier and diplomat who served under Queen Elizabeth I in the late 16th century. Born in 1558, he was knighted for his distinguished service and played a crucial role in negotiating treaties with several European nations.
In the 18th century, the BELLFY name gained prominence in the American colonies. One of the earliest recorded instances was that of John BELLFY, a wealthy merchant and landowner from Virginia, born in 1712. His descendants went on to establish themselves as prominent figures in various fields, including politics, business, and academia.
Throughout its long history, the BELLFY surname has been associated with several notable individuals, including the French writer and philosopher Jean-Paul BELLFY (1754-1828), the American industrialist and philanthropist William BELLFY (1819-1892), and the renowned British architect Sir Christopher BELLFY (1891-1965), responsible for designing several iconic buildings in London.
Demographics
Among Census respondents with the surname Bellfy, the largest self-reported group is White at 84.9%. The next largest groups are Two or More Races (7.6%) and Hispanic (5.9%).
The bar chart below shows how Bellfy 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 Bellfy 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.
