here in Germany
Wolfgang is such a common name (at least for older people) so hearing that it is first associated with
Wolfgang Amadeus is kind of funny. Same for
Marlene. I know
Marlene Dietrich but I don't think the name is that attached to her. Many people don't even know her. I know
Leni Riefenstahl but I think that you need to use a name to disattach it from a negative connection. I would also use let's say
Lilith or
Salome. When people see it on a child they immediately forget the first association with the "famous" person. The only exception is
Adolf. I think it would be difficult not to think of the person.
