Hello Cindy and list,
sorry, I never heard about Rosetta Stone tapes.
I looked up FEUstel on geneanet.org (the biggest French database). Most and oldest Feustel come from Saxony. In this case the writing could have been F�ustel, or Faeustel (back to the variations on the umlaut sound [eu])coming from Faust = fist. There are only 2 Feustel in France.
FUstel (with the French u sound which is � in German) on the other hand, is French.
So long
Colette
