If this group can't help me I might have actually reached the end of me rope.

I'm a retired employee of CKCO-TV in Kitchener and own and run the website ckco-history.com. On the site I have a page of all those (that I know of) who have worked in television or radio at 864 King St. W, Kitchener and have passed away.

The In-Memory page has so many people listed (almost 300) and a small number (6) who I've never been able to find obituary information about despite extensive searching. Some of these people have had a career in broadcasting. So if you can share any information about the following people I'd be most appreciative. 

Gord Butler (radio announcer); Paul Kudla (technician - died March 2015); Jack McLean (TV sales); Ron Prince (news); Lon Ritzo aka Duke Roberts (radio announcer - seems there was more than one with that alias); Bill Whiting (promotions manager)
