Origin
Meaning and origin of Marnocha
The surname Marnocha has its origins in Eastern Europe, specifically in the regions that are now modern-day Poland, Ukraine, and Belarus. It likely emerged in the 16th or 17th century as a derivative of the Polish word "marnować," which means "to waste" or "to squander." This suggests that the name may have been initially given as a derogatory nickname to someone who was perceived as wasteful or extravagant.
One of the earliest recorded instances of the name can be found in the parish records of the village of Stare Siolo, located in the Masovian Voivodeship of Poland, dating back to the late 17th century. In these records, the name is spelled as "Marnochowski," which is a more common variant of the modern "Marnocha."
As the name spread across Eastern Europe, different spellings and variations emerged, such as "Marnoha," "Marnokha," and "Marnokha-Marnokhatsky." These variations were likely influenced by regional dialects and linguistic differences in the areas where the name was adopted.
In the 19th century, the name gained some prominence with the birth of Ivan Marnoha (1823-1901), a Ukrainian Catholic priest and educator who played a significant role in the cultural and educational development of the Lemko region in present-day Poland and Ukraine.
Another notable individual with this surname was Maria Marnocha (1865-1924), a Polish-born American labor activist and suffragette. She was involved in the early labor movements in the United States and worked tirelessly for the rights of working-class immigrants and women's suffrage.
In the early 20th century, the name found its way to North America through various waves of immigration from Eastern Europe. One prominent figure from this period was John Marnocha (1892-1968), a Ukrainian-American artist and painter known for his landscapes and portraits depicting the life and culture of Ukrainian immigrants in the United States.
Towards the latter half of the 20th century, the name gained further recognition with the birth of Michael Marnocha (1941-), an American journalist and author who has written extensively on topics related to the environment, conservation, and outdoor recreation.
Another individual of note is Janina Marnocha (1928-2022), a Polish-Canadian artist and sculptor whose work has been exhibited internationally and is part of numerous private and public collections around the world.

The bar chart below shows how Marnocha 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 Marnocha surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Marnocha (2000, 2010, 2020).
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
