Origin
Meaning and origin of Dzubay
The surname DZUBAY is of Eastern European origin, specifically from the region of modern-day Ukraine. It is believed to have originated in the late 15th or early 16th century, possibly derived from an old Slavic word meaning "hollow" or "depression," referring to a geographical feature or a place name.
One of the earliest recorded instances of the name DZUBAY can be found in a historical document from the city of Lviv, formerly known as Lemberg, dating back to the early 1500s. This document mentions a local landowner named Petro DZUBAY, suggesting that the name was already established in the region at that time.
In the 17th century, the name DZUBAY appeared in several church records and tax registers in the villages surrounding the city of Khmelnitsky, which was then part of the Polish-Lithuanian Commonwealth. These records indicate that the name was prevalent among local farmers and landowners in the area.
One notable figure bearing the surname DZUBAY was Hryhoriy DZUBAY, a Cossack leader who lived in the late 17th century. He played a significant role in the uprising against Polish rule, fighting alongside the legendary Cossack hetman, Bohdan Khmelnytsky.
In the 19th century, a branch of the DZUBAY family migrated to the Russian Empire, settling in the region of modern-day Belarus. One member of this family, Ivan DZUBAY, born in 1832, was a prominent figure in the local community and served as a village elder for many years.
Another notable individual with the surname DZUBAY was Oleksandr DZUBAY, a Ukrainian writer and poet who lived from 1886 to 1962. He is best known for his works that captured the essence of rural life in western Ukraine and the struggles of the Ukrainian people during the tumultuous early 20th century.
While the surname DZUBAY is not among the most common in Ukraine or neighboring countries, it has a rich history that can be traced back several centuries, reflecting the cultural and historical ties of the region.

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