Tom,
There is little mention of DR in the 75th Anniversary book from 1996. It says, "the first golf tournament, a exhibition match, was held on August 5, 1922 on a course designed by Donald Ross." That appears to be it. The Club property was originally 5300 acres with 1400 along Lake Winnepaseukee. Some of that has been sold off, and some has been preserved, and the club's property today appears to be the area on the lake. It also mentions that more history can be found in "The Castle and The Club" by Betty Wilkin, wife of early member Colonel Wilkin.
I don't have time to scan pictures today, and am headed on the family vacation in a day or so, but if you want to see the book, just send me an IM and I can mail it out to you.
