My 5th great grandparents were Conrad Betz & Elizabeth Koser-Plasterer. Conrad's parents were Conrad & Margaretha Betz-Plasterer. Elizabeth's parents were Johann Jacob & Anna Margaretha Kindt-Koser. I've just recently started to collect infoon the Koser's and Plasterer's. I have the Plasterer's back to Heinrich Plasterer(Pleester) and the Koser's back to Leonhard Koser.
