Origin
The surname Buffett is believed to have originated in France, specifically in the region of Normandy. It is derived from the Old French word "bufet," which referred to a small table or sideboard. The name likely emerged during the Middle Ages, sometime between the 11th and 13th centuries.
One of the earliest recorded instances of the Buffett surname can be found in the Domesday Book, a manuscript compiled in 1086 by order of William the Conqueror. This document mentions a landowner named Rainald Buffett, who held property in the county of Hertfordshire.
Throughout the following centuries, the Buffett name continued to appear in various historical records across different regions of France. Notable individuals with this surname include Jean Buffett, a prominent merchant in the city of Rouen during the 16th century, and Marie Buffett, a renowned painter who lived in Paris in the late 17th century.
As the Buffett family spread across Europe, variations in spelling emerged, such as Buffet, Buffette, and Buffey. Some of these variants were likely influenced by the places where the family members settled, leading to the incorporation of local dialects or place names into the surname.
One of the earliest recorded examples of the Buffett surname in England dates back to the 16th century, when records mention a Thomas Buffett, who was born in Wiltshire in 1542. Another notable figure was Sir William Buffett, a prominent lawyer and member of Parliament, who lived in the 17th century (born in 1621, died in 1695).
During the 18th century, the Buffett family continued to establish roots in various parts of England and Scotland. One notable individual from this era was James Buffett, a renowned architect born in Edinburgh in 1754. He was responsible for designing several notable buildings, including the Royal Scottish Academy.
In the 19th century, the Buffett name gained further recognition with the birth of Benjamin Buffett (1809-1891), a successful businessman and philanthropist who made significant contributions to the city of Milwaukee, Wisconsin, in the United States.
As the Buffett family spread across different continents, the name continued to be associated with various notable individuals, including the American investor and philanthropist Warren Buffett, who is widely regarded as one of the most successful investors of the 20th and 21st centuries.
Demographics
Among Census respondents with the surname Buffett, the largest self-reported group is White at 68.8%. The next largest groups are Black (15.9%) and Two or More Races (9.6%).
The bar chart below shows how Buffett 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 Buffett surname at the time of the 2020 Census, not any inherent property of the name itself.
