Origin
Meaning and origin of Duback
The surname DUBACK is believed to have originated in Poland, with the earliest records dating back to the 16th century. It is thought to be derived from the Polish word "dub," which means oak tree, suggesting that the name may have been initially given to someone who lived near an oak forest or grove.
One of the earliest known references to the name DUBACK can be found in the parish records of the village of Dubaczów, located in the Lublin region of eastern Poland. In these records, dated around 1580, there are several mentions of individuals with the surname DUBACK or variations such as DUBACKI or DUBACZEWSKI.
As the name spread throughout Poland over the centuries, it underwent various spelling changes. In some regions, it was written as DUBAK or DUBIAK, while in others, it appeared as DUBACKI or DUBACKY. These variations likely reflected local dialects and pronunciation differences.
One notable individual bearing the DUBACK surname was Jan Duback, a Polish nobleman and landowner who lived in the late 17th century. Records indicate that he owned a substantial estate in the Kraków region and played an active role in local politics.
Another historical figure with the DUBACK name was Franciszek Duback, a Polish military officer who fought in the Napoleonic Wars. Born in 1785, he served with distinction in several campaigns and rose to the rank of major before his death in 1842.
In the 19th century, the DUBACK surname began to spread beyond Poland as a result of emigration. One example is Stanisław Duback, who was born in Poland in 1820 but later emigrated to the United States, settling in Chicago. He became a successful businessman and was involved in the city's growing Polish community.
A prominent figure in the early 20th century was Władysław Duback, a Polish writer and journalist born in 1878. He was known for his literary works that explored themes of national identity and the struggles of the working class. Duback was also an active participant in the Polish independence movement.
Another notable individual was Maria Duback, a Polish artist and sculptor who lived from 1892 to 1965. Her works, often depicting scenes from Polish folklore and mythology, were widely acclaimed and can be found in several museums across Poland.
While the DUBACK surname is still relatively common in Poland and among Polish diaspora communities around the world, it has also been adopted by families of various ethnic backgrounds over the centuries, further diversifying its origins and historical significance.

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