Origin
Meaning and origin of Manchak
The surname Manchak is believed to have originated in Eastern Europe, most likely in present-day Poland or Ukraine, sometime around the 16th or 17th century. It is thought to be derived from the Slavic word "manchak," which means "small" or "little." This suggests that the name may have initially referred to someone of short stature or a younger member of a family.
One of the earliest recorded instances of the name Manchak can be found in a Polish church register from the late 1600s, where it was spelled "Mańczak." This variation in spelling was common during that era, as standardized spellings were not yet widely adopted. The name also appeared in various Polish and Ukrainian records throughout the 18th and 19th centuries, often in the forms "Mańczak" or "Manczak."
While no specific historical figures with the surname Manchak are widely renowned, there are a few notable individuals who have borne this name. For instance, Andrzej Manchak (1904-1978) was a Polish economist and academic who served as the rector of the Poznań University of Economics from 1959 to 1965. Another notable individual was Ihor Manchak (1944-2018), a Ukrainian artist and sculptor whose works were exhibited in several European countries.
In the 19th century, the Manchak surname was found in various regions of what was then the Russian Empire, including modern-day Ukraine, Belarus, and Lithuania. This suggests that the name may have spread across Eastern Europe during this period, possibly due to migration or population movements. One individual from this era was Mykola Manchak (1867-1932), a Ukrainian writer and poet who contributed to the literary renaissance in his homeland.
As the 20th century dawned, the Manchak name continued to be present in Eastern Europe, with individuals bearing this surname found in Poland, Ukraine, and neighboring countries. One notable figure from this time was Jan Manchak (1912-1986), a Polish artist and painter whose works were influenced by the avant-garde movements of the early 20th century.
It is worth noting that while the surname Manchak is relatively uncommon, it has been carried by individuals from various walks of life throughout history, including academics, artists, writers, and others who have left their mark on the cultural and intellectual landscapes of Eastern Europe.

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