The Riesenfeld families of Langendorf and elsewhere

Several members of the Riesenfeld married members of the Gassmann / Nothmann family. Both families came from Zuelz and established themselved in the small rural town of Langendorf, now Wielowies northwest of Gliwice.
Below is a list of the earliest Langendorf-based members of the Riesenfeld families that I have found, mostly in JRI-Poland and hirschfeld.se. Each name is a link to the family tree descended from that person.
