Hi Malcolm. Thanks for replying. I'm afraid I only have the sketchiest of details. His given name is Robert, but apparently he did/does go by Bob. The only other things I know are his approximate height and appearance - 5'11 with dark brown hair and brown eyes, slim build. He would have been working in construction back then. I can't remember if he lived alone in Kitchener or if he had any other family there with him (ie parents, etc). I don't really have anyone I can get too many more details from, but I'm interested in locating the family if I can - I'm his daughter.
