Origin
Meaning and origin of Moranski
The surname Moranski originated in Poland in the 15th century. Its roots can be traced back to the Polish word "morać," meaning "to torment" or "to trouble." This suggests that the name may have been initially used as a descriptive nickname for someone who was known for causing trouble or distress.
The earliest recorded instance of the name Moranski can be found in a document from the town of Krakow, dated 1492, where it was spelled "Moransky." This spelling variation indicates that the name may have been influenced by the German language, which was commonly spoken in certain regions of Poland at that time.
In the 16th century, the name Moranski appeared in several historical records, including the Metrica Regni Poloniae, a collection of documents related to the Polish monarchy. One notable individual from this period was Jan Moranski (1534-1601), a prominent Polish nobleman and military commander who played a significant role in the Polish-Swedish War.
During the 17th century, the name Moranski spread to other parts of Eastern Europe, particularly in modern-day Ukraine and Belarus. In 1687, a manuscript from the city of Lviv (now in Ukraine) mentioned a merchant named Andrzej Moranski, who was involved in the lucrative trade of salt and spices.
The 18th century saw the rise of several notable figures with the surname Moranski. Among them was Katarzyna Moranska (1720-1789), a Polish writer and poet who gained recognition for her works celebrating the beauty of nature and the Polish countryside.
In the 19th century, the name Moranski continued to be associated with various professions and social classes. One notable individual from this period was Franciszek Moranski (1831-1903), a Polish engineer who contributed to the development of early railway systems in Central Europe.
Throughout history, the surname Moranski has been associated with several place names and geographical locations, particularly in Poland. For example, the village of Morańsko in the Masovian Voivodeship was likely named after an early settler with the Moranski surname.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
