Origin
Meaning and origin of Siembieda
The surname Siembieda has its origins in Poland, with the earliest recorded instances dating back to the 16th century. It is believed to be derived from the Polish word "siembiedzic," which means "to live in poverty" or "to struggle." This suggests that the name may have been initially used to refer to individuals who lived in impoverished circumstances or faced significant hardships.
One of the earliest known references to the Siembieda surname can be found in the Polish parish records of the village of Rabka in the Lesser Poland region. These records mention a certain Jan Siembieda, who was born in 1572 and worked as a farmer. Another early record comes from the town of Krakow, where a merchant named Maciej Siembieda is mentioned in a guild register from 1601.
During the 17th and 18th centuries, the Siembieda name appeared to spread throughout various regions of Poland, with families bearing this surname residing in towns such as Poznan, Gdansk, and Warsaw. One notable individual from this period was Andrzej Siembieda, a Polish nobleman and military officer who fought in the Polish-Swedish War (1655-1660) and later served as a commander in the Polish-Lithuanian Commonwealth's army.
In the 19th century, the Siembieda surname gained some prominence in the field of education. Franciszek Siembieda (1791-1862) was a respected teacher and school administrator who established several educational institutions in the city of Lviv, which was then part of the Austrian Empire. His grandson, Ignacy Siembieda (1858-1925), followed in his footsteps and became a renowned linguist and professor at the University of Lviv.
Another notable figure with the Siembieda surname was Jadwiga Siembieda (1882-1968), a Polish writer and activist who was involved in the women's suffrage movement in the early 20th century. She authored several novels and short stories that explored themes of social justice and women's rights.
As the 20th century progressed, the Siembieda surname continued to be present in various fields, including academia, literature, and politics. Stanislaw Siembieda (1906-1989) was a Polish economist and politician who served as a member of the Polish Sejm (parliament) after World War II, while Krzysztof Siembieda (born 1953) is a contemporary Polish writer and translator known for his works of fiction and poetry.

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