Ulle
Ulle is a given name and, less commonly, a surname of Germanic origin. In Scandinavian and German-speaking contexts, Ulle often functions as a diminutive or informal form derived from longer names such as Ulrich or Ulrik. As a nickname, it may be used independently in social or family settings, and in some cases it appears as a standalone given name in historical records or literary usage.
