I have a couple emails you could try. I am also looking for information re. Happy Valley. (Which I have listed as being in Lisle, Broome County NY ... ?)
Just remove the "REMOVE" from the email :)
Nancy Canfied: ncanf@REMOVEsan.rr.com
Tom Riley: Caryer99@REMOVEcs.com
Nancy seems to have some sort of census from the place. So try her first.
Emails should still be active! Good luck!
