Origin
Meaning and origin of Cihocki
The surname CIHOCKI originated in Poland, with its earliest known records dating back to the 16th century. It is believed to have derived from the Polish word "cichocki," which translates to "quiet" or "silent." This suggests that the name may have been given as a descriptive nickname to someone who was known for their quiet or reserved demeanor.
One of the earliest recorded instances of the CIHOCKI surname can be found in the parish records of the village of Cichocki, located in the Masovian Voivodeship of central Poland. These records date back to the late 1500s and mention several families bearing the CIHOCKI name.
In the 17th century, the CIHOCKI surname appears in various historical documents and records from the Polish-Lithuanian Commonwealth. These include land ownership records, tax rolls, and military service records. Some notable individuals from this period include Jan CIHOCKI (1620-1687), a Polish nobleman and landowner in the Kraków region, and Marcin CIHOCKI (1650-1712), a soldier who fought in the Polish-Ottoman Wars.
As the CIHOCKI name spread throughout Poland over the centuries, variations in spelling emerged, such as CICHOCKI, CICHOCKY, and CIHOCZKI. These variations were often influenced by regional dialects and the phonetic preferences of local scribes and record-keepers.
In the 19th century, the CIHOCKI surname gained prominence with the birth of Józef CIHOCKI (1815-1899), a renowned Polish philosopher and author who wrote extensively on the subjects of ethics and social justice. Another notable figure from this period was Franciszek CIHOCKI (1825-1892), a Polish artist and painter known for his landscapes and portraits.
The 20th century saw the CIHOCKI name spread beyond Poland's borders as a result of immigration and population movements. One notable individual from this era was Stanisław CIHOCKI (1905-1982), a Polish-American engineer and inventor who held numerous patents for his work in the field of electronics and telecommunications.
Throughout its history, the CIHOCKI surname has been borne by individuals from various walks of life, including scholars, artists, soldiers, and landowners. While its origins can be traced back to a descriptive nickname in 16th century Poland, the name has since become a proud symbol of Polish heritage and culture.

The bar chart below shows how Cihocki 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 Cihocki surname at the time of the 2020 Census, not any inherent property of the name itself.
