John,
Having read that Tillie was buried in Toledo, and having relatives there, many years ago I undertook the same search, on a cold snowy Easter weekend, only to find out after from Ron Whitten that Tillie was not there. Later, I noticed Tillie's Toledo address from a copy of his letter to Ross in Brad Klein's Ross book. I recognized it as being only a few blocks from my mom's apartment, and we drove by. The young African American men scared my Mom, as they seemed to be in gang looking regalia. I engaged them briefly in conversation.......at first they thought we were rent collectors and were ready to protect their momma. Even after explaining my interest in their house, they didn't want any part of me entering their mom's house to see the room where a somewhat famous guy supposedly died.
I also traced the route Phil Young wrote (based on Tillie's writings) that Tillie went to see his wife in the nearby hospital. There is an old hospital nearby, and it didn't make sense, but there are also several abandoned hospitals in Toledo, no bigger than a large house, so we can't be sure where he went.
I have been by Thomas' house at Pasa, Ross house (Dornoch, Pinehurst and MA), Tillie's NJ house, and a few others. I have seen Maxwell's grave, which has a nice Roman looking colums as entry to it right off the 17th tee.
I like the feeling of experiencing the aura of those guys. In the end, not sure what we learn, other than most led fairly modest lives and didn't have big edifice offices. Early on, I always figured creative genius would have to come from some fabulous office space, but it usually doesn't. And, in the end, no matter how accomplished, you still die. At least golf architects leave something behind in their work for us to remember them by, which is some consolation.....
