Brüngger
Brüngger is a Swiss surname of Germanic origin. It is believed to be derived from the Old High German word "brunno" meaning "well" or "spring" and the suffix "-ger," denoting a person associated with that place or feature. Therefore, Brüngger likely originated as a topographic name for someone who lived near a well or spring. Variations in spelling may exist. The name is primarily found in Switzerland and surrounding regions with historical Swiss influence.
