Origin
Meaning and origin of Andonov
The surname Andonov has its origins in Bulgaria, dating back to the late 15th century. It is derived from the Bulgarian given name "Andon," which is a variant of the Greek name "Antonios" or "Anthony." The suffix "-ov" indicates a patronymic form, meaning "son of Andon."
One of the earliest recorded instances of the name Andonov can be found in a 16th-century document from the region of Plovdiv, where a certain "Andon Georgiev" was mentioned. This suggests that the name was already in use during this period in central Bulgaria.
In the 17th century, the Andonov family was prominent in the town of Kotel, located in the eastern Balkans. Historical records mention an influential figure named Stoyan Andonov, who played a role in the town's governance and cultural affairs.
During the 19th century, as the Bulgarian National Revival movement gained momentum, several Andonovs made significant contributions to the cause of Bulgarian independence and cultural renaissance. Notably, Vasil Andonov Levski (1837-1873), a renowned revolutionary and one of the most revered figures in Bulgarian history, carried this surname.
Another notable bearer of the name was Georgi Andonov (1875-1945), a influential Bulgarian educator and author who founded several schools and wrote extensively on pedagogical topics.
In the early 20th century, Nikola Andonov (1876-1941) was a prominent Bulgarian politician and diplomat who served as the country's Minister of Foreign Affairs and later as an ambassador to several nations.
As the Andonov family spread across Bulgaria and beyond, variations in spelling and pronunciation emerged. Some alternative spellings included Andonoff, Andonoff, and Andonović, the latter being common among Bulgarians residing in Serbia and other neighboring regions.
While the name Andonov is predominantly found in Bulgaria, it has also been carried by individuals of Bulgarian descent in various parts of the world, particularly in regions with significant Bulgarian diaspora communities.

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