Where can I find the meaning of the German name Lauterman?

Question

The Lanterman name in USA is not necessarily related to the Lantermans in Germany, some are only related to Lautermans in Germany. What does the name mean? What is the origin?

Answer 1

Lauter is German for loud but this doesn't mean your ancestor shouted all the time. He could have been just the opposite - very quiet - and the comic nickname stuck as a family name.  

Answer 2

"loud" is not the correct translation when "lauter" is part of a family name

"Lauter" comes Old High German "lutter" and stands for "clean", "cleaned", "bright", "lucid" and "water"

some places, rivers and persons are named lauter today

Answer 3

It means loud man.
