Just came across your message, have you found the answer you were looking for yet? I knew that one day an old book, the "1972 Henderson's Calgary City Directory" that I have would come in handy someday for somebody. I looked up the address and found it was a house with the person's name who lived there. I had lived in Calgary at that time and believe the exact location was near the St. Mary's Cathedral in quite a nice district. Hope I have been of some assistance.
