Answered this one for you two posts earlier.
Not the one I had in mind. 
Part of this game has been that there are often multiple possible correct answers, and not just the one that the questioner is looking for. Have you asked the exact same two names four times now?
You answered correctly, I then answered someone else’s question correctly, and posed a question of my own, which hasn’t been guessed yet.
I don’t see the problem with acknowledging a correct, unexpected answer, and then trying for the original one again when given the opportunity. If that is against the rules, I will come up with a different pair.
My apologies; when I read you leading off that one with “Third time’s the charm,” I thought you were referring to it being the third time you’d offered that pair of names. I misinterpreted it.
Nope, that was me hoping that I hadn’t killed the thread.
Hatcher?
I’ll rerun one, then…

That wasn’t mine, but good one! And yikes, Charles Hatcher was a mean one.
I’m just going to spoil mine, since it was a little unfair (same spelling, different pronounciation)…it was Koch. Are heternoyms OK, for future use?
