Went to MMH this morning, after having emailed with Patty T. about the possibility of some Guelf materials still being there. It turned out they did still have a box. I went over and met with her and Alicia Fink (who it turned out taught in the Peace Corps program here later '60s). Enjoyable meeting, informative, and I have brought the materials here for study.
Alicia also invited me to serve on their board, which I said I would be happy to do. My name will be put forward at their next meeting. It could be a way to liaise between the different history groups in town.
