Steve: I only found information prior to Raynor beginning the course in 1915 in the Times articles........
What I did find was the chronological details about the founding of the course, Harmonie, Crescent, Glenwood etc and the info that Dev Emmet was the course designer (1912) for the course (under the Raynor course). That was about the first nine holes - I still don't know if he ever finished the other nine.
Raynor got paid the $1,800 to design and build North Shore, as you know.
Still NOTHING about Tillie. I don't think he could have done anything on the course after Raynor. Raynor's look is intact as far as I can tell (except the Biarritz hole seems different).
Could the club have just gotten the Tillie information wrong, and Bill Quirin just picked it up from them. Everything else seems cut and dry.
One day while I was there having some lunch - I looked at the place mat and saw what ended up to be the basic Raynor routing, right there in front of everyone. Go figure.
The scorecard on the placemat, on a 1933 scorecard and today's card are the same.
The back to back par 3's (#9 and #10) and the back to back par 5's (#3 and #4), confirms to me, one each of those holes were two of the five holes that he had to use on his new course. Raynor would not be building consecutive holes like that.
Also there is no Short on the course.
