Origin
Meaning and origin of Demidovich
The surname DEMIDOVICH has its origins in Belarus and Russia, tracing back to the late 16th century. It is derived from the Russian patronymic "Demidov," which translates to "son of Demid," a diminutive form of the Greek name Demetrius. The name likely emerged from the Russification of Greek names during the spread of Christianity in the region.
One of the earliest known references to the DEMIDOVICH surname is found in the Velizh district of the Smolensk region in Russia, where a family bearing this name owned land and estates in the late 1500s. The name also appears in various church records and census documents from the 17th and 18th centuries in both Belarus and Russia.
In the 18th century, the DEMIDOVICH family rose to prominence in Moscow, where Nikita Demidovich (1656-1725) established a successful mining and metallurgy business. His son, Akinfy Demidovich (1678-1745), expanded the family's industrial empire, becoming one of the wealthiest entrepreneurs in Russia during that era.
Another notable figure with this surname was Vasily Demidovich (1737-1793), a Russian statesman and diplomat who served as the Governor-General of Moscow and later as the President of the Russian Academy of Sciences. He was also a patron of the arts and supported the construction of several notable buildings in Moscow.
In the 19th century, the DEMIDOVICH surname gained recognition through the works of Mikhail Demidovich (1798-1869), a prominent Russian mathematician and educator. His textbooks on differential calculus and analytical geometry were widely used in Russian universities for several decades.
Other individuals bearing the DEMIDOVICH surname include Yevgeny Demidovich (1867-1942), a Russian military commander who played a significant role in the Russo-Japanese War and World War I, and Andrei Demidovich (1912-1994), a Soviet writer and playwright known for his works on World War II.
While the DEMIDOVICH surname originated in Belarus and Russia, it has since spread to other parts of the world through migration and diaspora communities. However, its roots and historical significance remain deeply tied to the regions where it first emerged and gained prominence.

The bar chart below shows how Demidovich 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 Demidovich surname at the time of the 2020 Census, not any inherent property of the name itself.
