I have the surnames Frodl, Langer, Janish, Riess, Doll, Keller, Kaupe, Kroul, Walter, Kratschmer and Apelt in my family tree, and many others. My family is from Michelsdorf, my mother was born in Landskron. I have a tree that shows eight generations, several families. The information was collected by a relative living in Landskron in the early 1900s.
