Aviva Pelham, now mostly retired, has been a South African operatic soprano for many years. Apart from having a stunning coloratura voice, she was also very beautiful and a splendid actress.
Unfortunately it's the name of an insurance company in Britain. I think it used to be called something like Norwich Union until a few years ago. It's a shame, really, because it's pretty & I'd like this name more if it didn't make me think of that company and their awful TV adverts.
