Here's the information from the Program committee:
Sue Lorraine, a member of the Association for Gravestone Studies from Utica, will present a lecture explaining symbols and epitaphs found on gravestones, and her experience giving cemetery tours for different historical groups. After her slideshow, we will use what we learned by looking at pictures of your own family’s gravestones. Bring prints or digital images on a flash drive. Also if you have a unique gravestone you may forward a photo beforehand to <email@example.com> and she might incorporate it into her slideshow!
I found the Association for Gravestone Studies has their own website here. Check out their information, and make sure you look at the Knowledge Center if you need some quick answers to your gravestone questions.
Hope to see you on Saturday!
