Some great additional research I was able to come across for North Hills Country Club in Menomonee Falls, including AW Tillinghast’s letter to the PGA redesigning the then-16th hole and tournament results from the 1940 Milwaukee Open (Hogan, Snead), 1951 Pabst Blue Ribbon Open (Snead), and 1961 Milwaukee Open (Nicklaus, Player, Venturi)
