My husband and I were really good friends with John and Sue Cudd years ago. At the time we knew John he was living in Dorchester Ontario (near London). He had two grown daughters from his first marriage (I believe one was named Adrian and the other had an unusual first name that I am unable to recall) and one daughter (Jennifer) from his 3rd marriage. We were very good friends with them from about 1984 until about 1987. He was an executive at McCormicks here in London.
He, Sue and Jennifer moved to Bamberg Ontario(near Kitchener) and it was after that time that we lost touch with him. John had some serious problems with alcohol and he and Sue dropped completely out of sight. We did receive one letter from him that was strange and disjointed, and we have been concerned and puzzled over his disappearance. I would say it is likely that our friend may be the person you are looking for. Please, if you do find him, would you let him know that Jim and Carlyn miss him, love him, and would dearly love to hear from him. Thanks.
