For a number of years, the history of Shinnecock Hills that I've heard is that Royal Montreal pro Willie Davis designed the first course there.
However, I'm presently reading H.B. Martin's "Fifty Years of American Golf" which includes a first-hand account of Willie Dunn discussing his design work there for Vanderbilt, et.al.
Does anyone know the true story, and interrelationship between the two Willie's?
