Dear Colleen, My parents John and Sue, called us to inform us of Mark's passing. Growing up there were many family occasions with the Graham family, and Mark always made a lasting impression on me. We were at the most recent family gathering, this time for Peter, and it was very evident to me that Mark, amongst other things, had not lost his sense of humour! Ann-Marie and I would like to pass on our most heartfelt sympathy and prayers.
