I spent time today checking over deeds and a few other items on the final day of the institute. Thanks to the deeds and a 1760 map of Salem [including Salem Village/Danvers and Peabody], I have a fair idea where the Twiss property was.
The banquet was OK and the after dinner speaker was very good. They announced the schedule for 2017. I'll list the classes on a later post.
I'll do some additional research tomorrow, then get ready to head home.
