Rob,
I'm really starting to question the 1892 attribution without further info. None of the periodicals I can find from that time mention it, unless, as I mentioned, it was the first course of a club that later moved.
However, I've ruled out the likely candidates, such as North Jersey CC. Preakness Hills wasn't a club til the 20's, and anything else just doesn't seem likely.
The course I'm most interested in near that immediate area is what today is called Scotch Hills GC, a 9-hole public course in Scotch Plains. Despite a very interesting history, I've been unable to determine who designed it originally. Bendelow? Dunn? Dunno!!
It opened in 1897 as Westfield Golf Club and when that club merged with Echo Lake CC in the early 20s, the club was sold to a membership of African-Americans, the first such club in the country.
Former Shinnecock pro John Shippen became the pro and the club was re-named Shady Rest Golf Club.
It remained as such for a number of years, becoming a public facility some years back. It has some of the wildest greens and most interesting holes on a very tight property I've ever seen.
