Origin
Meaning and origin of Zambrzycki
The surname Zambrzycki originates from Poland, a country known for its complex and regionally varied surnames. The name is typically associated with the Polish nobility and is considered to be toponymic. This means it likely derives from a place name - in this case, it is believed to be connected to the village of Zambrzyce, situated in the Podlaskie Voivodeship in northeastern Poland. The name Zambrzycki essentially means "of Zambrzyce," denoting someone who hailed from this particular location.
The earliest records of the surname Zambrzycki date back to the late medieval period in Poland. It first appears in written documents from the 15th century in various forms, including Sambrycze and Sambrycsky. These variations reflect the orthographic and phonetic changes occurring in the Polish language over centuries. Historical manuscripts and heraldic records are a rich source of information about the Zambrzycki family, highlighting their noble status and landownership.
One of the most notable early bearers of the surname was Jan Zambrzycki, a Polish nobleman born in the early 1500s. He was involved in several political and military activities during the reign of King Sigismund I the Old. Another significant figure is Stanisław Zambrzycki, an influential landowner and member of the Polish nobility in the 17th century, noted for his contributions to the local community in Podlaskie.
The name Zambrzycki also appears in the records of the Polish-Lithuanian Commonwealth, which existed from 1569 to 1795. Notable figures during this period include Adam Zambrzycki, an officer in the Polish-Lithuanian army during the 18th century, and Maciej Zambrzycki, a legal scholar and politician involved in the legislative processes of the Sejm, the parliament of the Commonwealth.
Throughout the 19th and early 20th centuries, the Zambrzycki family continued to play a role in Polish history. One prominent individual was Józef Zambrzycki, born in 1827, who was known for his involvement in the January Uprising of 1863 against the Russian Empire. Another significant person was Maria Zambrzycka, a writer and poet born in 1882, who enriched Polish literature with her works.
The surname Zambrzycki is deeply rooted in the history of Poland and is emblematic of the rich cultural and historical tapestry of the region. It continues to be a symbol of heritage and lineage among those who bear it.

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