So, there is this ice-cream/dairy store in the Midwest (maybe they have branched out further/farther than I know). The (company) name is "Oberweis".

Jokingly to a German friend, I said "Oh, we should go into the store and tell them that that's not a German word."

I thought maybe "Oberweis" was a made up name like "Häagen-Dazs".

He, northern German, proceeded to tell me "That sounds like a typical southern German name".

Lo and behold, on their website (Oberweis'), it says that it from a family name.

Do you know how family names do somehow mean something or are derived from something in language? What would "Oberweis" mean if it could?
