I am related to Casper Glatfelter through my great-great grandmother Sarah Glatfelter-Grimm.Her father was Johannes(John)Glatfelter married to Catherina Simmons. His father was Johannes who's father was Casper. I found all this in the book Glatfelters by Don and Jeanne Hartman. I was at the last reunion, but I sorta crashed as I didn't know for sure at that time if I was related or not. Sarah's son was Henry Grim, and his daughter was Emma Jane Grim, my grandmother. If you would like all the information I have I would be happy to share.
