Origin
The surname "DUBLO" is of Polish origin, tracing its roots back to the 14th century. It is believed to have derived from the Old Polish word "dublo," which referred to a specific type of woodland or forest clearing. The name was commonly found in the regions of Silesia and Greater Poland, where many families bearing this surname resided.
One of the earliest recorded instances of the surname "DUBLO" can be found in the Akta Grodzkie, a collection of judicial records from the Polish-Lithuanian Commonwealth, dating back to the 15th century. These records mention a landowner named Maciej DUBLO, who held property in the village of Dubice, near the town of Kalisz.
In the 16th century, the name "DUBLO" appeared in the Metryka Koronna, a series of books containing official records of the Polish Crown, where it was associated with a noble family from the Kraków region. A prominent member of this family was Jan DUBLO (1525-1592), a respected military commander who served under King Sigismund II Augustus.
The surname "DUBLO" can also be linked to several place names in Poland, such as the villages of Dublovice and Dublovka, which likely derived their names from the Old Polish word "dublo." These place names may have influenced the spelling and pronunciation of the surname over time.
Another notable figure bearing the surname "DUBLO" was Franciszek DUBLO (1690-1758), a Polish Catholic priest and theologian who authored several influential works on religious doctrine and moral philosophy.
In the 19th century, the name "DUBLO" gained prominence in the literary world with the birth of Andrzej DUBLO (1825-1890), a celebrated Polish poet and translator whose works explored themes of patriotism and national identity.
Throughout its history, the surname "DUBLO" has been associated with various other notable individuals, including Katarzyna DUBLO (1780-1855), a renowned Polish philanthropist and social reformer, and Jan DUBLO (1910-1985), a distinguished Polish mathematician and educator.
Demographics
Among Census respondents with the surname Dublo, the largest self-reported group is White at 93.9%. The next largest groups are Hispanic (2.6%) and Two or More Races (2.6%).
The bar chart below shows how Dublo 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 Dublo 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.
