"btw..it's also my understanding that Colt visited both the newly opened Merion and still developing Seaview in the 1913 timeframe, although I don't have my source(s) in front of me at the moment or recall exactly where I came to that understanding."
Mike Cirba:
For starters it may've been from the fact of that letter of Colt's to Hugh Wilson around 1920 when Colt mentioned to Wilson that Mrs Colt would like to be remembered to Mrs Wilson.
So where would they have met---in England or in Philadelphia?
It seems someone came up with a ship passenger manifest that showed Mrs Colt traveling with Harry over here in either 1913 or 1914 so obviously Colt and Wilson must have gotten together at Merion then. Maybe Harry and the missus actually stayed with Hugh and his blushing bride!
I don't think anyone has any ship passenger manifest listing of Mrs Wilson going to England with Hugh in 1912 or any other time, does one? But what do I know---maybe there are a ton of ship passenger manifest lists out there somewhere that have never been digitized!
Don't worry, I do realize when that possible fact is mentioned to some of our iconoclasts of golf architect "LEGENDS" on here it is met with dismissals or complete silence.
