Origin
Meaning and origin of Cieplik
The surname CIEPLIK is of Polish origin, first appearing in historical records during the 15th century. It is derived from the Polish word "ciepły", meaning "warm" or "hot", suggesting a possible occupational origin for someone who worked with heat or fire, such as a blacksmith or baker.
One of the earliest documented instances of the name can be found in the records of the town of Krakow, where a certain Jan CIEPLIK was mentioned in a legal document from 1487. The name also appeared in the records of the nearby village of Wieliczka, where a family of salt miners bearing the surname CIEPLIK were registered in the late 16th century.
In the 17th century, the CIEPLIK name began to spread throughout other regions of Poland, with notable individuals including Marcin CIEPLIK (1612-1683), a renowned potter from the town of Kielce, and Katarzyna CIEPLIK (1648-1721), a respected herbalist and midwife from the village of Dobczyce.
The 18th century saw the rise of Jakub CIEPLIK (1725-1798), a successful merchant and landowner from the city of Poznan, who was known for his philanthropic efforts in supporting local schools and churches. Another notable figure was Tomasz CIEPLIK (1771-1842), a respected scholar and linguist who authored several works on the Polish language and its dialects.
In the 19th century, the CIEPLIK name gained prominence with the birth of Adam CIEPLIK (1823-1891), a celebrated poet and playwright whose works were instrumental in shaping the Polish literary canon of the Romantic era. He was followed by Zofia CIEPLIK (1845-1915), a pioneering educator and advocate for women's rights, who founded one of the first schools for girls in Warsaw.
Throughout its history, the CIEPLIK surname has been associated with numerous individuals who have made significant contributions in various fields, including the arts, academia, and public service, reflecting the rich cultural heritage of Poland.

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