I'm not absolutely sure this is he, but I found an Ira Ellette Bradley who died August 7, 1926 in Jackson Co. OR. Certificate #181. No other info was shown.
This was under "Oregon Death Index". When I searched the Jackson Co. USGEN Web I see where they have listed names for ones they have death certificates for. His name was listed. If you would like to order his death certificate to be sure this is the correct one you can go on the website and get the address. Or, you might try just doing a search for "Jackson Co. OR Death Certificates". (They also had one on a Mabel Juanita Bradley Cert #267. Not sure she was kin.)

Not sure if you have this, but I also found Martha Bradley in 1930 living with her son by her first marriage, Ralph L. Coleson and Gladys in Grand Haven, Ottawa, MI. She was still living with them in 1940 in Marion, Oceana, MI. He was listed as son, and a Clergyman, just like Ira was.

Find a grave for Martha Coleson Bradley: Buried Hart Cem. in Oceana, Co. MI. Dates 1861 - 1943. Died at age 82.

(I was interested in searching for you because I was born in Burnett Co. WI, but live in VA.)
