Hello Heather, Thanks for your efforts, I think the John Drysdale you found is the same one that is mentioned in the book: "Lac La Biche : yesterday and today. Year of birth is correct, ex service man, living in Alberta. I was quite excited when I found him! unfortunately he is NOT The John Drysdale I am looking for.
But if you could check the phone book I would appreciate it as it may open a new lead. Reagrds Kyffin
