I believe Belle Warden may have been married to a Otto Schroedter on 14 September 1916 in Deadwood, Lawrence County, S.D. I believe they may have been living in Casper Ward 1, Natrona, Wyoming in 1920. The census is very hard to read, and comes up under the name of Arnold, Bell, and Hiram W Schwerdt. Could not find Luella Bell in 1930. Possible this older Otto Arnold Schroedter had died, and she may have married again. Possible that they may have moved back to Texas, as there are some Schroedter family living in Texas.
Hiram Clay Warden(Worden) is living in Aberdeen, Grays Harbor, Washington in 1930 with his wife, Phyllis, children, and Myrtle Lamb, listed as his sister in law, but I believe is his sister, and some Pendergraft nieces and nephew.
