I didn't find an obituary, funeral or death notice for William J. Bentley. I searched The Oregonian newspaper from 30 Jan through 11 Feb 1938. I used the Oregon Death Index to verify the date of death as 29 Jan 1938 and found he died in Portland. The death certificate was number 331.
The only thing I found for Mrs. Eva Bentley was her funeral notice. It was in The Oregonian, section 1, page 12, col. 7, Friday, July 13, 1934 and reads as follows:
"BENTLEY--Funeral services for Mrs Eva Bentley, wife of W. J. Bentley, will be held Saturday, July 14, at 2 P. M. at the St Johns Funeral Home. Interment Columbian cemetery." The Oregon Death Index listed the death certificate as #1909.
I called the St. Johns Funeral Home and asked if they handled the Funeral for William J. Bentley, and gave them the date of death. They had no record of him in their book. I also called the sexton for the Columbian cemetery, regarding William. They didn't have any record of William's burial, just the burial of Eva Bentley. I checked with Willamette National, the cemetery for military burials, and they didn't have any record of William's burial.

In some of the Polk's Portland City Directories, from 1904 thru 1936, there were entries regarding a W. J. Bentley and Wm J. Bentley. In 1904, Wm J.

Polk address in 1934. In 1936, Wm J. Bentley was listed as living at 9035 N. Tioga Av. (Note": There was a Wm B. Staines living at this 9035 N. Tioga Av address in 1934.)
