I, too, am trying to trace people in this area, but coming from the McCrohan angle.
What I believe I have so far is
Eugene Owen McCrohan, dancehall promoter, and father of Denis and Jerry (McCrohan/Edmonton/Mars Bonfire...Steppenwolf...)
was married to Margaret (Miller??), and that Eugene's father was also eugene.
I'd be very interested in any more info in this area..
