Etzel, Erdt, Kirby, Stephen(ste-f-en) or Stephenitz, Tazwell .

The last name listed was the man who invented the breed. Etzel was just as important as rin tin tin in jumpstarting the breed after the world war when anything German had a negative fee, including the GSD. Erdt, Tazwell, and Kirby are Austrian family names of mine carried down through the years.
