Hi Jim

I'm sorry, Susan Backwell isn't one of mine. However, if you google Pat Backwell you will find there is a Pat Backwell who is a marine biologist in Australia and who has published a lot of work. I dod correspond with her some time ago and she was originally from South Africa so it may well be a relative of hers. I'm sorry, but I don't have her email address any more.

Good luck

Pat
