Melvyn, While I have no access to the research you request, and it was very difficult to read the entire article posted, I consider it highly probable that the source cited in the article was in fact not a Scotsman, but rather a Canadian, C.B. Macdonald.
The timing is concurrent with C.B's attempt to raise awareness of the game (and funds for the inevitable Chicago Golf Club) in and around Chicago.
My source is a book titled something along the lines of "100 years of Chicago Golf". In it the author writes that CB was openly ridiculed during those early days of trying to spread the word. It was not until the Columbian Exposition of 1893 when world travelers came to the city was he able to raise the funds for the first 18 hole course in America.
