Hello, You are referring to my great-grandfather. His son was Albert, his son was Theodore, my father. I have many, many generations of information, both back and forward from Charles. Please send a private email and we'll share data. I am using Family Tree Maker so it is easy to keep track. Regards, Jim p.s. Did you know there is a Tetzlaff Road and a Tetzlaff farm, occupied by Duane Tetzlaff?
