I found your Christian Delzer at the Odessa3 archives. Son of Gottlieb Delzer and Barbara Staiger (m. 20 May 1851 Rohrbach, Russia). I have been helping someone with Delzer lineage here in America. Her family went to Mercer County, ND (married a Sailer). All of these Delzer's come from Johannestal, Russia. My Bohrer family is also from Menno. My Walz's and Isaak's also settled in Hutchinson county, SD.
