>>6282941Because you can't tell German and Jewish names apart doesn't mean nobody else can.
Both parts of the name matter, Feldmann for example is not very Jewish. But then Feldman is the Jewish version of that name and quite different already.
Then you have also the first part of the name that matter, here "Feld" just means "field" and isn't very Jewish, but prefixes that refer to their work as jewelers such as Goldman, Silverman, or to colors like say Greenman or Schwarzmann, are more likely to be Jewish.
Keep in mind those aren't absolutes and we are dealing in likelihoods here.
I understand that to you all those names must sound equally ambiguous, but it's not the case to everybody.
