German names

Ever wondered how Surnames/Family Names were derived? Notice that some english names could be related to one's ancestor's profession. Such examples like, Smith(Blacksmith?), Porter, Shakespear (Spearman?), Archer (like Johnny Archer), Miller, and Shepherd.

Same goes for Germans here, at a larger extent i think, like Bauer(farmer), Schmidt (Smith),...

or some famous Germans...


Schumacher, maybe shoe maker?


Claudia Schiffer ( could be mariner, or someone who deals with ships)


Bastian Schweinsteiger (Pig stepper, hey, its still a profession)

and This is what I found quite a while ago in Salzburg. (Lower center)

Should be an obvious translation for those who don't know german.
