Origin
Meaning and origin of Sesin
The surname Sesin has its origins in the South Slavic region, particularly in Croatia and Serbia. It can be traced back to the 12th century, where it was derived from the Slavic root word "ses," meaning "to sit" or "to settle." This suggests that the name may have originally referred to a person or family who settled in a particular area.
One of the earliest recorded mentions of the name Sesin can be found in a document from the Dubrovnik archives, dated 1284. This document refers to a man named Nikola Sesin, who was involved in a land dispute. Another early reference is found in a manuscript from the Hilandar Monastery in Mount Athos, Greece, which mentions a monk named Sava Sesin in the 14th century.
The name Sesin was also present in the Venetian-controlled region of Dalmatia during the Middle Ages. In the 16th century, there are records of a noble family named Sesin in the city of Sibenik, which was then part of the Venetian Republic.
One notable figure bearing the surname Sesin was Pavao Sesin (1616-1679), a Croatian Catholic priest and writer who authored several religious works. Another prominent individual was Nikola Sesin (1734-1808), a Serbian Orthodox priest and writer who played a significant role in the Serbian national revival movement during the late 18th century.
In the 19th century, the surname Sesin appeared in various regions of the Austro-Hungarian Empire, including present-day Croatia, Serbia, and Bosnia and Herzegovina. One notable person from this period was Jovan Sesin (1838-1912), a Serbian lawyer and politician who served as the Mayor of Belgrade in the late 19th century.
Another influential figure was Mirko Sesin (1870-1945), a Croatian writer and journalist who was active in the early 20th century. He was known for his poetry and contributions to Croatian literature.
While the surname Sesin has its roots in the South Slavic region, it has since spread to other parts of the world due to migration and diaspora communities. However, its origins and historical significance remain deeply rooted in the Balkan region and its rich cultural heritage.

The bar chart below shows how Sesin 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 Sesin 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.
