names for Nigel

Nigel Price wrote: I look forward, when I get to read the printed version of the story, to seeing how all the names are spelled. All my efforts in this and my previous message are just "best guesses" based on what I heard on the dramatised reading. Is it "Baden" or "Badden"? And how is the shark-man's name spelled? "Hange"? And talking of names, I realise that I never discussed the name of the missionary on the island. His full name is - from memory - something like "Mervyn Robertson" or "Robinson", but he doesn't like his given name and prefers to be called "Rob". As some of the other names in the story are clearly significant, I wondered what Rob's name might indicate.
