Origin
Meaning and origin of Jambor
The surname JAMBOR is of Hungarian origin, and it first emerged in the late 15th century in the region that is now modern-day Hungary. The name is derived from the Hungarian word "jámbor," which means "pious" or "virtuous." This suggests that the name was likely given to individuals who were perceived as particularly devout or morally upright in their communities.
One of the earliest recorded instances of the JAMBOR surname can be found in a 16th-century Hungarian census record, where a family by the name of JAMBOR was listed as residing in the village of Sárospatak. The name also appears in several other historical documents from the region, including church records and land registries.
During the 17th and 18th centuries, the JAMBOR name began to spread beyond Hungary, as members of the family migrated to other parts of Europe. In 1687, a man named János JAMBOR was recorded as having settled in the town of Skalica, which was then part of the Kingdom of Hungary but is now located in present-day Slovakia.
One notable individual with the JAMBOR surname was Pál JAMBOR (1756-1813), a Hungarian scholar and writer who was a prominent figure in the Hungarian Enlightenment. He authored several works on philosophy and literature and is considered an important figure in the development of Hungarian intellectual thought.
Another significant bearer of the JAMBOR name was József JAMBOR (1821-1892), a Hungarian politician and lawyer who served as a member of the Hungarian Diet (parliament) in the late 19th century. He was a vocal advocate for Hungarian independence and played a role in the struggles against Austrian rule.
In the 20th century, Antal JAMBOR (1909-1983) was a Hungarian-born American chess master who achieved the title of International Master in 1950. He was a prominent figure in the chess community and authored several books on chess theory and strategy.
István JAMBOR (1925-2015) was a Hungarian artist and sculptor who gained recognition for his abstract and modernist works. His sculptures and installations can be found in numerous public spaces and galleries throughout Hungary and Europe.
Finally, Vilmos JAMBOR (born 1949) is a contemporary Hungarian writer and poet who has published several collections of poetry and prose. His works often explore themes of identity, memory, and the human experience, and he is regarded as one of the leading literary voices in modern Hungarian literature.

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