Clarifying name possibilities

I'm proposing some possible names and asking for confirmation. We've got "Freimann," "Frey," and "Freud," which could easily be confused. Then there's also the "Frehner brothers" in Swiss hockey, but that's a dead end it seems. I should ask a specific question instead, like referencing "Freitag" or "Bernoulli." I'll try asking for clarification about which Freimann brothers the user means. They might be related to a family in Zurich involved in a watch business, perhaps? I'll suggest they share more context.
