The #8,724 most common surname in the United States (2010 Census) — about 1 in every 82,135 Americans shares it.
Etymology
Krouse is most likely a German surname that entered English-speaking countries through immigration and spelling variation. In many cases, surnames of this type arose as altered forms of older German names, often nicknames or short forms based on a word for a physical trait, animal, or descriptive label. The exact root of Krouse is not certain without family-specific records, and it may reflect a regional variant spelling rather than a single fixed original word.
History
The surname is found in the United States mainly among families of German or German-American background, where spellings were often adapted to local pronunciation and record-keepers. Krouse can overlap in appearance with related surnames such as Kraus, Krauß, Krause, and Krouse-like spellings that developed through migration and anglicization. Because the spelling is variable, different family lines with this surname may not share one single origin.
