I am on the line of Jacob Troyer and Katherina Kirchofer. I believe it would be GGG grandmother. My great grandmother Carolina Flora was the daughter of Aaron Troyer, son of Katherina. I have a copy of a wonderful pen and ink drawing of a large spreading "tree" that shows 6 generations of David Kirchoffer born 1759 died 1839 (according to the tree) it was drawn in 1909 by a family member Sem Geiger. The tree shows all of Katherin and Jacobs children, their children and their children plus++. pretty amazing. I am working on this line, if you have any further info or want me to check for a particular person on the tree let me know the links and I'll get back to you.
