Kim,
I checked the Joplin Globe on Ancestry, and their records online don't start til July, 1955 and Claude died 6-23-1955. You might check with the Joplin Library and have them check their obit. files. They have a lot of obit. files. Another place to check might be Pierce City, Mo. since that is where he is buried. Also I found a lot of Boucher's listed on the Lawrence County web site.
