William T. Gardiner and Josephine G. Gardiner had a son named Walter Gardiner born in 1913 in Pocahontas County, Grant, Iowa.  The 1915 Iowa census confirms this.  A family memoir states that he died in a forest fire in 1918.  I have been unable to locate a death record, tombstone or article for little Walter Gardiner (1913-1918).  Any help would be greatly appreciated.
