Looking for players to interview

I am at the stage where I need to talk with more former players to get their view on playing hockey in Victoria. Also, I need to talk with descendants of those early players who pioneered the sport here. I just sent off letters to some former players and to two sets of descendants. There is no way I can do a cold call by telephone, so have to do it the old-fashioned way via snail-mail. Hoping for good results.
