Did you see Anna Hayes' post about Emile's succession record? I looked at the Acadia Parish index and found that it was opened on 1/24/1926 less than a month after his death. It is succession #1527. While I was at it, I looked for a succession for Leon Garot and found it. It was opened on 12/10/1912, #881. These documents should provide you with good information. You might learn something about Emile's wife on his succession document.
I checked google maps and found that Familleureux, Belgium is about 16 miles from Glabais, Belgium. Both are located south of Brussels...Glabais is closer at 23 miles.
