This might be him - an obit for Elmer C. RAY appeared in the "Baton Rouge Morning Advocate", edition of 11 July 1986. The online archives go back only to 1995 so your best bet might be to contact East Baton Rouge Public Library @ 225-231-3750. They have complete back issues of "The Advocate" on microfilm and might be willing to furnish a copy for a modest fee. If that doesn't work, visit RAOGK, there is a volunteer there who offers to do free lookups. Hope this helps.
