Looking for Ian

I am looking for IAN DEAN or possibly DEANS. I have very little information but hopefully someone may be able to help.

Ian lived in BALHAM in and around 1966/ 1967, he would at that time been around  eighteen years old (give or take a year), so he will now be about seventy, his father was a policeman at that time.

Ian and friends went on holiday or school journey to Ostend in Belgium at about that time where he met a young lady from Sheffield. They formed a friendship that lasted after the holiday with the young lady visiting Ian in Balham and he visiting her in Sheffield. Unfortunately they at some stage lost touch with each other, it may have been that the young ladies mother was extremely ill and needed alot ov attention and care.

That you ng lady Theresa, generally called Terry, is now hin her early seventies and has severe memory issues, especially of current events etc., but she has never forgotten Ian.

I pro mised her I would do my best to try and find him and see if he remembers her, it would perk her up no end if I could not only find Ian  but also get a word from him to Terry.

Thanks for reading this and hopefully helping.
