Origin
Meaning and origin of Lotarski
The surname Lotarski is believed to have originated in Poland, with the earliest records dating back to the 16th century. It is derived from the Polish word "lotarz," which means "archer" or "bowman." This suggests that the name may have originated from a person who was skilled in archery or worked as an archer.
One of the earliest recorded instances of the name Lotarski can be found in the parish records of the village of Łotarze, located in the Masovian Voivodeship of central Poland. The village name itself is likely related to the surname and may have been named after an individual with the name Lotarski or a group of people known for their archery skills.
In the late 16th century, a nobleman named Jan Lotarski was mentioned in a historical document detailing the ownership of land and estates in the Lublin region of eastern Poland. This suggests that the Lotarski family had achieved a certain degree of prominence and social status during that time period.
During the 17th and 18th centuries, the name Lotarski can be found in various Polish records, including birth, marriage, and death registers, as well as land ownership documents. One notable individual from this era was Marcin Lotarski (1672-1734), a Catholic priest and theologian who served as a professor at the Jagiellonian University in Kraków.
In the 19th century, the Lotarski name was well-established in various regions of Poland. Michał Lotarski (1809-1887) was a Polish landowner and politician who served as a member of the Galician Diet, which was a regional parliament in the Austro-Hungarian Empire.
Another notable individual with the surname Lotarski was Wacław Lotarski (1875-1942), a Polish architect and urban planner. He was responsible for designing several important buildings and urban developments in Warsaw and other cities during the early 20th century.
Throughout its history, the Lotarski surname has been associated with various occupations, including archery, landownership, religious services, politics, and architecture. While the name originated in Poland, it is likely that individuals bearing this surname can now be found in various parts of the world due to migration and diaspora.

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.

Does the Census include every surname?
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.
