Matthew -
In talking to the powers that be at Golf Digest, I have been told that the research they did show Des Soutar (given name Daniel Gordon Soutar, but went by nickname of Des) collaborated with Mick Morcom on the design of Kingston Heath in 1925. If you have evidence to the contrary, please forward to Ron Whitten.
In addition, if feel GD is continuously printing erroneous information, please contact Ron as well. He would prefer hearing from you directly as opposed to me passing on the information.
