I was just thinking that no matter which church Emile belonged to or was buried from, he had to have gone through a funeral home. The funeral home record would list the cemetery where he was buried. I found that the records from some of the funeral homes in Acadia Parish have been published. The Acadia Parish Library has copies of the books. I don't know what dates are covered, but it might be worth e-mailing the library to find out if Emile is listed in any of the books.
The Gossen Funeral Home is in Rayne and the Geesey-Ferguson Funeral Home is in Crowley.
