After I had written, I remembered that it may be possible that the obit appeared in the New Orleans paper. The papers are on the Internet and I checked both Baton Rouge and New Orleans. However, though the Baton Rouge paper begins at 1/1/1986, the New Orleans paper does not begin until 1/1/1989. Therefore, though you can not check on the Internet, perhaps someone can check at a library. You may want to go to the Orleans Parish Message Board and ask for an obit lookup in "The Times Picayune". Or, you could also try the East Baton Rouge Parish Message Board. The State Library has the NO papers on microfilm.
I would look it up, but I don't have access to the newspapers on microfilm.
Sorry for the confusion.
