Finn

Finn derives primarily from the Old Irish name Fionn, meaning bright or fair, borne most famously by Fionn mac Cumhaill, the legendary Irish hero and warrior-seer central to the Fenian Cycle of mythology. The name also functions in Scandinavian languages as a reference to someone from Finland or of Sámi heritage, giving it a distinct parallel etymology in the Norse tradition. In modern use across English, Dutch, and German-speaking countries, Finn is often treated as an independent given name drawing on both traditions. Fionn, Finnan, and Fingal are closely related forms, while Flynn derives from the same Old Irish root.
