Origin
Meaning and origin of Dorobiala
The surname DOROBIALA is of Polish origin, dating back to the medieval period. It is believed to have originated in the region of Lesser Poland, particularly in the areas around the city of Krakow. The name is derived from the Polish word "doroba," which means "to acquire" or "to earn," and the suffix "-iala," which is a variant of the more common "-ala" ending often found in Polish surnames.
One of the earliest recorded instances of the name DOROBIALA can be found in the Ksiega Laudow, a collection of land records from the 15th century, where it appears as "Dorobiala." This suggests that the name was already in use during that time period and may have been associated with someone who had acquired wealth or property.
In the 16th century, the name DOROBIALA appears in the records of the Jagiellonian University in Krakow, indicating that a person with this surname was either a student or a professor at the institution. This provides evidence of the name's presence in the academic circles of the time.
A notable historical figure bearing the surname DOROBIALA was Jan DOROBIALA (1567-1629), a Polish nobleman and military commander who served under King Sigismund III Vasa. He played a significant role in the Polish-Swedish War of 1626-1629 and was celebrated for his bravery and leadership on the battlefield.
Another individual of note was Katarzyna DOROBIALA (1742-1810), a renowned Polish artist and painter who gained recognition for her portraiture and religious works. Her paintings can still be found in several churches and museums across Poland.
In the 19th century, the name DOROBIALA appears in connection with the village of Dorobialka, located in the Małopolska region of southern Poland. It is possible that this place name is derived from the surname itself, reflecting the presence of families bearing this name in the area.
Other notable individuals with the surname DOROBIALA include:
1. Stanisław DOROBIALA (1885-1958), a Polish writer and journalist who contributed to several literary publications during the early 20th century.
2. Janina DOROBIALA (1901-1987), a Polish educator and women's rights activist who advocated for equal opportunities in education and the workforce.
3. Tadeusz DOROBIALA (1923-2002), a Polish engineer and inventor who held several patents for innovative manufacturing processes.
4. Andrzej DOROBIALA (born 1952), a contemporary Polish artist known for his abstract paintings and installations.
5. Małgorzata DOROBIALA (born 1975), a Polish businesswoman and entrepreneur who founded a successful technology company in Warsaw.

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