Origin
The surname KROL is of Polish origin, derived from the Polish word "król" meaning "king." It is a noble surname that traces back to the medieval period in Poland, where it was likely adopted by individuals with royal connections or those who served in the court of a monarch.
The earliest recorded instances of the KROL surname can be found in Polish historical records and documents dating back to the 14th and 15th centuries. One notable example is the mention of a nobleman named Jakub KROL, who lived in the city of Krakow during the reign of King Casimir III the Great in the mid-14th century.
In the 16th century, the KROL surname appeared in the records of the Polish-Lithuanian Commonwealth, which was a union of the Kingdom of Poland and the Grand Duchy of Lithuania. During this period, the name was associated with the szlachta, the noble class of Polish society, and was often used by members of the gentry and landed aristocracy.
One of the most prominent figures bearing the KROL surname was Jan KROL, a Polish military officer and nobleman who lived in the late 16th and early 17th centuries. He served as a general in the Polish-Lithuanian army and played a significant role in the Polish-Muscovite War of 1609-1618.
Another notable individual was Piotr KROL, a Polish writer and poet who lived in the 17th century. He was known for his religious works and poetry, and his writings were widely circulated among the Polish nobility and clergy of the time.
In the 18th century, the KROL surname gained prominence in the Polish territories under the rule of the Russian Empire. One notable figure from this period was Jakub KROL, a Polish landowner and philanthropist who lived in the late 18th and early 19th centuries. He was known for his charitable works and his support for educational initiatives in his local community.
During the 19th century, the KROL surname spread beyond Poland as Polish immigrants and their descendants settled in other parts of Europe and the Americas. One noteworthy individual was Stanisław KROL, a Polish-American journalist and activist who lived in the late 19th and early 20th centuries. He played a significant role in the Polish-American community and advocated for Polish independence from foreign rule.
Throughout its history, the KROL surname has been associated with nobility, military service, literature, and philanthropy in Poland and among Polish communities around the world. While its origins can be traced back to the medieval period, the name has endured and continues to be a recognizable surname of Polish heritage.
Demographics
Among Census respondents with the surname Krol, the largest self-reported group is White at 94.7%. The next largest groups are Two or More Races (2.5%) and Hispanic (1.9%).
The bar chart below shows how Krol 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 Krol surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
