"In all the article there was never any mention of a connection with Westbrook. I know Westbrook and Suffolk County Club were both in East Islip, but I'm not sure how far or near they were. The nine at Westbrook predated SCCC by a number of years (and lasted longer too). I suspect SCCC was near the location of Timber Point."
Tom MacWood:
Not that it means all that much from a golf architectural perspective, but I think these various clubs---eg Westbrook, Suffolk County and Timber Point all might have some interesting connections.
It appears that Westbrook GC, a nine hole course and club, was built very early, perhaps just after the original 12 hole Shinnecock by Willie Dunn. It seems it might have been part of the substantial Bayard Cutting property, also called "Westbrook, in East Islip. Cutting had bought the property from Pierre Lorrilard (who had created the massive estate) when Lorrilard bought Tuxedo Park and moved there in 1888, also creating a golf course (perhaps also by Willie Dunn).
H.B. Hollins, Marion's father, was the first president of Westbrook G.C., and it was where Marion learned to play golf under the tutelage of Arthur Griffth, a professional and clubmaker Hollins had met at Royal St George's and brought to America with him, even though her family had a three hole course on their massive estate, "Meadowbank" that was apparently next to Westbrook GC.
According to that clipping you posted, the Suffolk County GC and course was created on H.B. Hollins and G.V. Hollins' land (perhaps 115 acres somewhere on the 600 acre "Meadowbank Farm"?) in 1914, which would make sense as Hollins went bankrupt in 1913.
In the early 1920s the exclusive membership of Westbrook GC decided they needed an 18 hole course and so they bought land in the vicinity, perhaps another part of Cutting's or Hollins' property and created the ultra-exclusive Timber Point (membership limited to 100).
