I hadn't thought that much about it but the story of Marion hitting that shot is sometimes assumed to have been something she did when Mackenzie was there but on a closer reading one sees it was Raynor she was with when she did it. Raynor died in Jan 1926. If she hit that shot with Raynor it probably means that hole was set at that point as a potential par 3 and Mackenzie sort of inherited it as part of the routing, even though how to actually do it seemed to at first confuse him.
And Mackenzie did mention that he used as his "shot tester" Lapham's son who he said was really long.
I feel the story has truth but some of the numbers and distances may've gotten a bit skewed in the telling. But the thing is Pat, Marion Hollins really was long, very long and somehow you don't seem willing to accept that fact.
I recommend to everyone to get the biography about her as it portrays a person who was not just a good golfer (for instance she may've been one of the best woman polo players ever and as a "Four-in-Hand Driver" she apparently had no woman peer or perhaps no peer at all) but a really remarkable person in all kinds of other ways but not without some complexities for sure.
As a visionary, a natural born risk-taker, a globe trotter, a woman with more friends and connections than I've almost ever heard of she was just something else. But even with all that she seemed to be (at least so many said of her) that she was or could be very mild-mannered and at times even a bit anti-competitive in a way that might be termed "overly generous." All-in, that may've had something to do with the fact she may've been inherently shy and just over compensated in some of the things she imagined and tried.
To me she didn't seem to be particularly proprietary either with some of her projects, such as Women National which it seems she started and then sort of lost some touch with when she moved west. To "shot test" for the hole concepts of Women National she picked her great friend and three time US Amateur champion, Alexa Stirling of Georgia, to do the shot testing figuring if she did it herself it would not be representative as she knew how unusually long she was.
"A Woman in a Man's World" is an excellent title for a biography of Marion Hollins. She was a TRULY remarkable person for sure who like many of her ilk and era ended up with too much tragedy. And then there was her pretty much lifelong cross to bear of her father, the inimitable Harry Hollins, big-time financial risk taker who actually went broke in 1913 thereby precipitating the giving up of the incredibly rich and fortunate life Marion grew up into in New York and Long Island.
What a gal.
PS:
She was also The Babe's original mentor in golf and taught the Babe from her beginning.
PPS:
When asked why she never married her response was something like: "I'm too busy to do that."
