Well, you might not remember, but before Ishi said Rias was from Gaburias, someone theorised that it's from a chess piece or something like that. So your case might be similar. I get what you try to say by we need to choose what we believe to be correct, but what I say is still the same: As long as the author (Ishi, in this case) didn't mention it to be so, whether in the story or outside of it, and you say it's so, then you theorise it to be so, you assume it is that way. That's all I said.
