Origin
The surname Filimonov has its origins in Russia, deriving from the Russian given name Filimo, which itself is a variant of the Greek name Philemon. The name Philemon comes from the Greek words 'philos' meaning 'beloved' and 'monos' meaning 'alone' or 'solitary'.
Filimonov is a patronymic surname, meaning it was originally formed by adding the possessive suffix '-ov' to the name Filimo, indicating 'son of Filimo'. Patronymic surnames were common in Russia and other Slavic countries, as a way of identifying individuals based on their father's given name.
The earliest recorded instances of the surname Filimonov can be traced back to the 16th century in various Russian historical documents and church records. One notable example is the mention of a Filimonov family in the Vologda region of northern Russia in the 1590s.
During the 17th and 18th centuries, the Filimonov surname began to spread across different regions of Russia as families migrated and settled in new areas. In the 19th century, several individuals with the surname Filimonov achieved recognition in various fields.
One such individual was Nikolai Filimonov (1804-1857), a prominent Russian architect who designed several notable buildings in St. Petersburg, including the Church of the Savior on Blood. Another was Ivan Filimonov (1835-1891), a renowned Russian painter known for his landscapes and genre scenes.
In the 20th century, Vasily Filimonov (1900-1983) was a Soviet military officer who served as a general during World War II and played a significant role in the Battle of Kursk. Andrei Filimonov (1923-2001) was a renowned Russian linguist and philologist who made significant contributions to the study of the Russian language.
One of the earliest recorded place names associated with the surname Filimonov is the village of Filimonovo, located in the Ryazan region of central Russia. This village likely took its name from an early settler or landowner with the surname Filimonov.
Throughout history, variations in the spelling of the surname have included Filimonoff, Filimonof, and Filimonovich, reflecting regional dialects and transliteration practices. However, the spelling Filimonov has remained the most prevalent form of the surname in Russia.
Demographics

The bar chart below shows how Filimonov 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 Filimonov 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.
