We have traced our line back to this man as well. I have seen the Family Bible that was purchased by Hannes in 1564. It is located in the Archive Library at Conrad Grebal Mennonite College on the University of Waterloo, Ont. Campus. The family history is all there..and had been transalted to English and is included. Contact me for further info if you don't already know about this. Will be interesting to find out which line you are from. My gggg Grandfather was Christian at Doon ON..
