Can you help us with any of these names?

We currently have 119 names on our contact list. Unfortunately, we have had no success tracing the following 40 people. Time is beginning to run out for us to be able to get in touch with them and invite them to the reunion. We would be tremendously grateful if you could read through the list to see if by any chance it includes anyone you can contact and let Neil know asap. Thanks!
