Thankyou very much for your comprehensive answer to my question.As I am going away from home for a few days I will print your answer and study it more fully. However I get the feeling that the answer to part of my problem will be a redesign of the website. Particularly the early pages. I wish that I could just ring up someone and get the offending google entries removed but that appears to be impossible. At least to my very basic knowledge.
Once again thanks for you help.
