John Green made many contacts who shared the stories they heard in their areas with him. Two of them for the Vancouver area were Bruce McKelvie and Charles Cates.

Bruce Mckelvie was a journalist and historian, who spent time listening to the stories told by the people in the area. He was known to keep silent if asked to and never told of the secret encounters. Charles Cates, Mayor of North Vancouver, also collected stories of these creatures. Both of these men recorded these tales long before anyone thought to keep any sort of systematic records. Unfortunately, most of what they knew was lost when they died in the late 1950s.
