Kerchival Hundley died 11/24/1955 at age 63 in Cameron Parish. His death is recorded in vol.13/page 568. You may obtain a certified copy of his death record from the LA State Archives [3851 Essen Lane - Baton Rouge, LA 70809] for a fee of $5.00. The response is usually very quick. You may also want to look at the cemetery records for Cameron Parish which are to be found on the Cameron Parish Archives. However, it may be that Kerchival died, but did not live in Cameron Parish. He may have been buried in Alexandria. The death certificates today give the cemetery; however, I don't know if that applied to 1955.
I did not find a death record in LA for Gladys Hundley. She may have lived to a very old age and thus the death record would not be available online.
Hope this helps.
