This continues a series of posts, done in a very efficient (make that speedy fast) manner to share some research on the ancestors.  This is NOT intended to be the end all to end all report.  It's a work in progress, to show you what I have found, right or wrong. Kind feedback is welcomed via comments.

From the May 14, 1930 issue of the Iowa Recorder, Greene, Butler County, Iowa:
     "Allison
     Mr. and Mrs. Warren Stowe, Eagle Grove, came for an extended visit in the Mrs. Alice Codner home."  (I found the image at Ancestry dot com.)
From prior research I had made the following research notes: 
 
1. Not shown in the WPA cemetery listings for Wright County, Iowa (1935 era).  ** I discovered recently he died in 1938, a good reason to NOT show up in a 1935 cemetery listing.
2. His death record was not found in the Wright County, Iowa death records.  ** I found recently he died in Cherokee County.
3. A search of the Clarion, Wright County, Iowa and Eagle Grove, Wright County, Iowa papers was made and no obituary was found.  ** I still have not found an obituary.
Edward Warren Stowe. **Noting the difference in the middle name, which has been used before, see news article above.
