Origin
Meaning and origin of Kaucic
The surname Kaucic has its origins in Slovenia, a country located in Southern Central Europe. It is believed to have emerged during the late Middle Ages, around the 13th or 14th century. This name is derived from the Slovene word "kavčič," which means a small house or a cottage.
One of the earliest recorded mentions of the name Kaucic can be found in a historical document from the 15th century, where it was spelled as "Kawchicz." This document was a land registry record from the region of Carniola, which was part of the Duchy of Carinthia at the time.
In the 16th century, there are records of a notable individual named Jurij Kaucic, who was a blacksmith and a landowner in the village of Loka pri Žusmu. He was born around 1520 and passed away in 1587.
During the 17th century, the name Kaucic was also associated with the town of Idrija, which was known for its mercury mine. One of the earliest recorded miners with this surname was Janez Kaucic, who worked in the Idrija mine from 1638 to 1672.
In the 18th century, the name Kaucic gained prominence in the region of Carniola, which was part of the Habsburg Monarchy at the time. There are records of a family of landowners and farmers named Kaucic who lived in the village of Žiri. One notable member of this family was Matija Kaucic (1718-1796), who was a respected farmer and a member of the local council.
As the centuries passed, the name Kaucic continued to be prevalent in various parts of Slovenia, with some individuals bearing this surname migrating to other regions and countries. One notable figure from the 19th century was Jurij Kaucic (1829-1901), who was a renowned architect and designer responsible for several notable buildings in Ljubljana, the capital of Slovenia.
The surname Kaucic has maintained its presence in Slovenia throughout history, and it is still a relatively common surname in the country today. While it may not be as widely recognized globally as some other Slovene surnames, it remains an important part of the country's cultural heritage and linguistic diversity.

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.

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.
