Origin
Meaning and origin of Fribourg
The surname Fribourg has its origins in Switzerland, specifically in the town and canton of the same name. The name is derived from the French word "freideborg," which means "free town," reflecting the town's status as a free imperial city during the Middle Ages. The town itself was founded in the 12th century and became a prominent center of trade and culture in the region.
The earliest recorded instances of the Fribourg surname can be traced back to the 13th century in various Swiss documents and records. One notable example is the mention of a "Petrus de Friburgo" in a document dated 1287. The variant spelling "Friburgensis" was also commonly used during this period to refer to individuals from the town of Fribourg.
In the 14th century, several members of the Fribourg family were recorded as holding prominent positions within the town's government and ecclesiastical institutions. One such individual was Jean de Fribourg, who served as the mayor of Fribourg in the late 1300s.
As the surname spread beyond Switzerland, it underwent various spelling variations, including Fribourg, Frybourg, and Friburg. In France, the name was sometimes recorded as Fribourg-en-Brisgau, referring to the town of the same name in present-day Germany.
Throughout history, there have been several notable individuals bearing the Fribourg surname. One of the earliest was Johann von Fribourg (c. 1330-1392), a Swiss theologian and philosopher who taught at the University of Paris. Another was Pierre de Fribourg (1525-1584), a French jurist and diplomat who served as the ambassador to the Holy Roman Empire.
In the 17th century, Jean-Baptiste Fribourg (1612-1685) was a French architect and engineer who designed several notable buildings in Paris, including the Church of Saint-Sulpice. Later, in the 18th century, Jean-Jacques Fribourg (1737-1810) was a Swiss painter and engraver known for his landscapes and etchings.
In more recent times, one of the most prominent individuals with the Fribourg surname was the Swiss author and playwright Max Fribourg (1886-1958), who wrote numerous plays and novels exploring themes of Swiss culture and identity.

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 Fribourg surname at the time of the 2020 Census, not any inherent property of the name itself.
