Following different conversations regarding the family name Rauch here comes an information out of Germany , which might be interesting. The correct English translation of Rauch is, of course, smoke, but when the family names where given in the middle ages, there was another kind of meaning of Rauch and that was used in most of the cases when the names were given as an attribute and to describe someone. In old German there was no differentiation between "rauh" (which means rough or hairy/haired) and rauch (smoke). Martin Luther used in his first translation of the bible "rauch" and ment "rough/hairy". He wrote "Esau ist rauch" = Esau is rough. Rauch is a very old Germanic word, used for rough and other hard things like "rock" or in old bretonic "roc'h" or haired skin. That's why we still use the word Rauchwaren (waren means article) in German not for smoking articles, but for furs. Or when you analyze the family name Rauchmaul (maul means mouth) it describes a man with a beard. In the majority of cases when Rauch guys received a coat of arms it shows a so called "wild man", which is a legendary man, a myth, living in the woods, naked, the body very haired and some leaves around his hips and a crown of leaves on his head in different varieties. This myth person (like a griffin) stands for strength, roughness and wildness. In heraldic terms we talk about a talking coat of arms (rauch=rough/haired=wild man). My family was awarded in the 16th century with a coat of arms by king Ferdinand II, showing a wild man with stick of iron in his hands ready to fight. It was probably given for merits in the turkish wars to defend Vienna. I know a lot of wild men in Rauch coat of arms with swords et cetera. So when the name Rauch was given it mostly describes an attribute = the rough guy.I just know two meanings of Rauch in a name for smoke, that's Stubenrauch (Stube means room).This described someone who was a barber-surgeon. And Huettenrauch (huette means hut) which meant a charcoal-burner). By the way, I could pursue my Rauch ancestors back to 1550 in Lower Bavaria. Rauch is an old Bavarian name. I hope this information is helpful in a way.If somebody would like to have more information, please send me an Email.
