Crotty
An Irish surname, probably from a Gaelic personal name or nickname rather than an occupation or place-name.
The #8,793 most common surname in the United States (2010 Census) — about 1 in every 82,862 Americans shares it.
Etymology
Crotty is generally treated as an Irish surname of Gaelic origin, though the exact derivation is not certain. Nineteenth-century surname scholars linked it with other Irish names in a way that suggests a personal-name base rather than an English occupational source, but they did not reach a fully secure explanation. In modern reference works it is usually treated as an anglicized Irish family name whose original Gaelic form and literal sense are uncertain or debated.
History
The name is found chiefly in Ireland, especially in the south and east, and later appears in emigrant communities abroad. Historic surname surveys record it as an established Irish surname by the 19th century, but the available excerpts do not preserve a detailed early pedigree or clan history. Because the etymology is not firmly settled in the excerpts, the historical note should be read cautiously.

Fun fact
In 19th-century surname indexes, Crotty is often listed alongside other Irish names without a full derivation, which is a good reminder that not every common Irish surname has a single agreed explanation.
