I find an Andreas Delzer in the records at Odessa3 for Rohrbach, Russia (b. 21 Sep 1885) to Christian Delzer. Also an Andreas Delzer married to Elisabetha Raff (m. 12 Oct 1882). Also an Andreas Delzer married to Katharina Schaefer (m. 6 Nov 1878) all in the Johannesthal, Russia records. Any of this make sense?
