Have you been to visit the Puslinch Historical Society? If not, your really should make a point of visiting them and seeing what they have to offer. They have posted a lot of content online on their website http://www.puslinchhistorical.ca/ but have so much more to offer in person. Visit the archives and see for yourself!
Note that for 2019 their new office hours are Noon to 3pm every Saturday and they can be found inside the Puslinch Library (29 Brock Rd. S.). See you there!
