Hello,I knew a David Sydenham who lived in Dulverton in the Sixties. He was a Personnel Officer at the Butlins Holiday Camp in Minehead.We were great friends for a while until I emigrated to Australia. I do believe he moved to Portsmouth at some point because his mother had already moved there to be nearer his sister. I hope this will be of help to you. If you do trace him and it is the David I used to know could you please tell him that Pat the nurse who went to Australia said to say hello and pass on my e-mail address. He was a very nice man and I would love to know what happened to him. Good luck. Pat adams.
