Jeff:
That's a terrific pick up on your part about what Joe Bunker said in 1915 about Wilson going abroad, and how he may've used even a single word ("originally') to lead future researchers/analysts and history writers to an historically inaccurate assumption and conclusion.
Add to that the remarks about this from Wilson's brother in 1926 that were apparently also misinterpreted and misunderstood by later researchers/analysts and history writers to mean a 1910 trip abroad (in his 1926 report to Philler Alan Wilson did not actually say Hugh Wilson went abroad in 1910!!----but apparently someone at some point assumed and concluded that was what he meant!!
).
Also notice that Richard Francis seems to be the one who added the information in 1950 for researchers/analysts and history writers that Wilson returned with surveys and sketches from abroad.
It looks like at some point perhaps within the next 35 years after Francis' article that the idea Wilson spent seven months abroad and in 1910 got interpreted somehow.
And then we get to 2009 when David Moriarty proved via a ship manifest that Wilson in fact traveled abroad in the spring of 1912 and returned in early May 1912, thereby scotching that old 1910 trip abroad story. I potentially bracketed that trip by producing the last date (March 1, 1912) of a letter Wilson wrote from Philadelphia, thereby scotching the seven months abroad story (which may've been initially verbally recounted as something like "several" and misiinterpreted into "seven."
).
So the truth is he went abroad for no more than two months in the spring of 1912.
And then there is that mention in an article perhaps in late 1912 or early 1913 by Alex Findlay in which it seems Wilson essentially told Findlay he had never been abroad before or at least not to study golf architecture.
And then in 2009 we have this essay "The Missing Faces of Merion" that assumes and concludes that, SINCE the 1910 and seven months abroad trip in preparation for designing and creating the course is not true, THEREFORE it can be concluded that Wilson and his committee could not have routed and designed Merion East because they were too inexperience and therefore actually incapable of routing and designing Merion East before building it (Moriarty's over-arching "Novice" premise
), and that they had therefore only been the constructors of the course to someone else's routing and design----eg CBM and/or HH Barker!!
The above, Jeffrey, is a chronicle of the history and evolution of interweaving rumors that eventually combined over time to produce some very historically inaccurate stories about the true architectural history of the course and who the architects actually were.
Thankfully the Merion historians and some others here have gone back to MCC's archives and found the administrative records from 1910 and 1911 and on that prove to a large extent what really happened back in 1911 with the routing and design and then the construction of the golf course and who largely was responsible for it all.
But as we can see from these on-going and long running Merion threads, old intertwining rumors, not based in fact, are very hard to break!
