It would be great if someone could interview that lady. But my advice would be to not waste any time at all in doing that interview.
I'd planned to interview PVGC's fifty year super, Eb Steineger in two weeks and he died within one week. I'd scheduled a meeting with Joe Dey to interview him on his vast and perhaps unique knowledge of the evolution of the Rules of Golf and he died the next week.
I did manage to interview George Crump's (who died in Jan 1918) caddie this summer. Just to look at a man who knew Crump sort of blew my mind since Crump died so long ago. And a few years ago I did interview a Shinnecock caddie who knew the club even before Flynn built this iteration in 1929. And I've found a man who lived at Oakmont who remembers the course from the early 1920s. He even caddied there for Sarazen. I also interviewed McGovern's daughter who remembered Ross like a favorite uncle. She knew nothing about his architecture but her recollections of him were wonderful.
I hate to be pessimistic in any way but the fact is when one interviews people who knew these men we talk about who worked and lived so long ago be somewhat prepared to be disappointed.
The reasons for that are various and sometimes unexpected. Crump's caddie who is 100 now was quite healthy and of sound mind indeed but the fact was he was just about completely deaf and I found myself virtually screaming at him (not a great way to carry on a good give and take interview) and he still had a hard time figuring out what I was asking or saying. So I tried to write what I was asking and I guess he's blind enough to things close to him to be able to read them. For instance you should have seen him trying to figure out the printed word---A.W. Tillinghast.
Connie Lagermann, Flynn's daughter who remembers things from the mid 1920s was another interesting case. She just didn't know that much about the architectural details of his work for the simple reason that she claimed he worked so hard and was away so often from home and his family the very last thing he wanted to do when he came home to his family was talk about the details of what he was doing when he was away from them which she claims he always felt so badly about.
My prediction and advice about that lady who worked for Colt would be the same as Tom MacWood's. Ask her about Colt, the man, and what he was like. If you asked her detailed questions about his architecture and his philosophy on it, my prediction would be she probably never knew much of that anyway.
Crump's caddie said something to me in this vein that was just so poignant, and frankly so touching. As I was leaving he said he was very sorry he couldn't help more with the things he knew I was after but that I must understand that the things a 9-10 year old boy caddying for Crump back then was thinking about were just very different from the things I was after and asking him about.
