Nüsslein
Nüsslein is a surname of German origin. It is derived from the Middle High German word "nüzlin," which means "little nut" or "nutlet." The name likely originated as a nickname for someone who was small, perhaps resembling a nut, or for someone who collected or sold nuts. As with many surnames, it may have also been an occupational name for a seller of nuts. The name is found predominantly in German-speaking regions, including Germany, Austria, and Switzerland. Variations in spelling may exist due to regional dialects and historical transcription practices. The prevalence of the surname Nüsslein is relatively low compared to more common German surnames.
