You may also wish to check out a Bill MacDonald that played for the Thunder Bay Vulcans in 1971 72. He was born  in 1953 so it may be that he is from the same family as the Bill MacDonald you are looking for whose name is on the patch. A long shot but maybe he could steer you in the right direction. Go to website     www.hockeydb.com     and search Bill MacDonald     good luck
