Krupa
A Slavic surname usually linked to a word for grain, groats, or pebbly grit.
The #8,138 most common surname in the United States (2010 Census) — about 1 in every 75,803 Americans shares it.
Etymology
Krupa is a common Slavic surname built on a word found in several related languages meaning 'groats,' 'cracked grain,' or sometimes 'hail/grit.' In Polish and some neighboring languages, the surname is often taken as a nickname or occupational name tied to grain processing or a coarse, grain-like texture. Because the same root is widespread across Slavic speech, the exact sense can vary by family line and region.
History
The name is well established in Central and Eastern Europe, especially in Polish, Slovak, Ukrainian, and South Slavic areas. It spread more widely through migration to North America in the 19th and 20th centuries. In some cases it may also reflect a local nickname based on appearance, character, or a place name derived from the same Slavic root.

Fun fact
The same Slavic root behind Krupa can refer not only to groats but also, in some languages, to hail or coarse granules, which is why the surname can have more than one plausible shade of meaning.
