I found my old question and thought I would add some information for any other relatives researching.
John L Harms d 1924-- I found him and Baby Anna Harms at JANSEN CEMETERY and added photos to FindAGrave.
David T Thiessen who died 1/18/1906 and Helena Born Thiessen died 6/27/1909 were SUPPOSEDLY BURIED AT THIESSEN CEMETERY AND THEN MOVED TO JANSEN CEMETERY BUT THERE IS NO GRAVESTONE.
The Jansen Cemetery is northwest of the town of Jansen, Nebraska. And the Thiessen Cemetery is east of the town but which Mennonite Church was it connected with?? If anyone has further information I would be very interested.
