Mike,
The last article you posted mentions a present club house. Do you know the location of the original club house?
I think the statement of the 14 acres the club now held title to was only to differentiate it from the land the golf course was located on. The land for the golf course may have been acquired by lease or mortgage? The article makes it sound like they had acquired enough land for an 18 hole course which was scheduled to open on Memorial Day 1922.
Sven cites his Al Williams article on the Willie Park Jr. thread from August 22, 1922. Perhaps this article contains information on all 18 holes? The article wasn't posted in the thread, so I don't know exactly what it says.
Researching stories on Linwood Country Club may help your search too. If Al Williams built a second nine holes at Maplewood, it most likely would have been around the same time or just after he worked at Linwood. There was a quote of: "Harry W. Williams, who has been the pro at Galen Hall links, will go to the new Linwood Country Club at Linwood, near Atlantic City, after the first of the year" from The Evening Public Ledger-December 28, 1920. Linwood opened their first five holes in March of 1921. I wonder if this was Al's brother? The story from Hartford mentioned he had a brother in the business.
