Origin
Meaning and origin of Mozuch
The surname "MOZUCH" is believed to have originated in Poland, likely in the late 16th or early 17th century. It is thought to be derived from the Polish word "mozuch," which means "young man" or "lad." This suggests that the name may have initially been a nickname or descriptive name given to a young man or a son.
One of the earliest recorded instances of the name can be found in the parish records of the village of Kozuchow, located in the Lublin region of eastern Poland. In these records, there is a mention of a Marcin Mozuch in the year 1612. This could indicate that the name was already in use in that area during that time period.
During the 17th and 18th centuries, the name appears to have spread to other parts of Poland, as well as to neighboring regions such as modern-day Ukraine and Belarus. In these areas, variations of the spelling, such as "Mozuchowski" and "Mozuchowicz," were also used.
In the late 18th century, a notable figure named Jan Mozuch (1745-1819) was a prominent Polish military officer who fought in the Kosciuszko Uprising against the Russian Empire. He was born in the town of Tarnogrod and later served as a colonel in the Polish army.
Another individual of historical significance with the surname Mozuch was Franciszek Mozuch (1810-1892), a Polish writer and journalist who was active in the mid-19th century. He was born in the town of Opole and is known for his works on Polish history and culture.
In the late 19th century, the name began to appear in immigration records as individuals with the surname Mozuch started to emigrate from Poland to other parts of the world, particularly to the United States and Canada. One such immigrant was Stanislaw Mozuch (1865-1932), who was born in the village of Wroblin and later settled in Chicago, Illinois.
Another notable figure with the surname Mozuch was Maria Mozuch (1892-1972), a Polish writer and activist who was born in the town of Tarnopol (now in Ukraine). She was involved in various cultural and educational initiatives aimed at promoting Polish language and literature.
It is worth noting that while the surname Mozuch is relatively uncommon, it has been carried by individuals from various walks of life, including military personnel, writers, journalists, and immigrants, throughout its history.

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 Mozuch 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.
