I am interested in the preceding family surnames of Dudweiler. Of particular interest is information on Maria Kopp born 12/17/1768 married to Johannes Quartz born 5/5/1761. Johannes was son of Johann Nikolas Quartz and Ann Maria Gross. Maria Magdalene Kopp was daughter of Georg Jacob Kopp and Maria Magdalene Parret. I have no information on this Kopp family in Dudweiler. Thank you, Dave
