Why would it be stupid for Brandish to not be the name she was born with?

Brandish isn't exactly a common name, to put it lightly.

And I also wouldn't be surprised if she was close to Zeref. She's certainly fiercly loyal to him even though she seems quite lax any anything else. That makes me think there's more to their relationship than just the usual master-servant relation.
