Origin
Meaning and origin of Dziewior
The surname DZIEWIOR is of Polish origin, originating in the late medieval period around the 15th century. It is derived from the Polish word "dziewior," which means "brother-in-law." This name likely originated as a descriptive nickname for someone who had a close relationship with their brother-in-law or as a way to distinguish individuals in a community.
The earliest recorded instances of the DZIEWIOR surname can be found in historical records and documents from the region of Lesser Poland, particularly in the areas around Krakow and Tarnow. In these old records, the name is sometimes spelled with variations such as "Dziewior," "Dziewior," or "Dziewiorek."
One of the earliest known individuals with the DZIEWIOR surname was Jan Dziewior, a merchant who lived in Krakow in the early 16th century. Historical records from 1521 mention his involvement in trade dealings with neighboring towns.
Another notable figure was Mikołaj Dziewior, a prominent landowner and nobleman from the village of Bochnia in the late 16th century. Records from 1587 indicate his ownership of substantial land holdings in the region.
In the 17th century, the DZIEWIOR name was also associated with the village of Łapanów, near Tarnow. A church record from 1643 mentions a Jakub Dziewior as a resident of the village.
During the 18th century, the DZIEWIOR surname began to spread beyond the Lesser Poland region. Franciszek Dziewior, born in 1735 in the town of Rzeszów, was a skilled carpenter who worked on several notable buildings in the area.
Towards the end of the 19th century, the name DZIEWIOR gained recognition with the birth of Stanisław Dziewior (1871-1947), a Polish politician and diplomat who served as the Minister of Foreign Affairs for a brief period in 1919.
Throughout its history, the DZIEWIOR surname has maintained its roots in Poland, with various individuals bearing the name making contributions in various fields, from trade and agriculture to politics and diplomacy.

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.

Keep in mind that these are self-reported numbers.
