Do you have Edward Palmer's obituary? If yes, what does it say about Claude? If not, here's the specifics.
An Edward Franklin Palmer b. 16 Sept. 1873 died 1 June 1942, Idaho Falls, Bonneville Co per death cert #127456. Source: Idaho Death Index 1911-51.
I'd contact Random Acts Genealogical Kindness and request a copy of his obituary. Go to www.raogk.org
, read guidelines, choose Idaho, choose Bonneville County.
Idaho Falls Public Library, 208-612-8460.
Hopefully that will contain info about where Claude was living.
I couldn't find death info for Ella. Maybe she died after 1956.
I'd also contact the Bonneville County Historical Society, 200 N. Eastern Ave, Idaho Falls, 83402 and ask if they have anything on Claude.
Maybe he changed his surname back to Tomlinson? I'd check the court records in the last county he lived in.
I found a Claude E. Tomlinson b. 10 Oct 1896 who died 31 Jan 1973. His soc. sec. # was assigned in Missouri before 1951. Source: Social Security Death Index. However, I don't know if he was YOUR Claude. Successful Searching & Happy Holidays!
