I know Peter is deceased but Iona lived in Alton and she may still be there.
There's an old thread here

that may give you a contact to ask.
My friend Lionel is still playing but they're not on the net and snail mail from and to NZ is rather slow. I don't know if that phone number would help - if he lives in Alton and Iona lived there too, I'm sure their paths would have crossed.
I can't see any obit on the net.
