Pete:
Have you ever seen "The History of Fall River Country Club" ?
I had some correspondence with J.W.L. Adams, Oxon, England some years ago. We pretty well established evidence that the Grand Golf Tournament by Professional Players had a pose by Wm Dow which was almost identical to the pose in the FORWARD, at the Somerset Junction Station, on the Old Colony Line, which was adjacent to the FRGC in 1900.
The golf club house was destroyed by fire in 1909. Jack Howard, the green-keeper, Willie Dow, the club's professional, and the club's servants were able to get most of the furnishings and club trophies out safely.
Adams, and the History, gave A.H. Fenn credit for the first course in 1900. The 2nd course layout was made sometime after 1910, and credit was given to Tom Winton, who came to America from Montrose Scotland to work for Willie Park, Jr.
Don't know the background for the Cornish/Whitten documents.
