Hi Courtney - I live in Lake Charles and have a subscription to their e-newspaper "The American Press". I did a search this morning and found the name "Matilda Louise Horn Johnson" stating her husband was W. D. 'Pat' Johnson and the article was about a local artist named Will Ousley. The article stated Matilda was a grandaughter of Will Ousley and she was born in the Ousley house & raised by the Ousley's. This article was printed 22 Mar 2002.
I also searched for a Bobby Jean Grant but nothing came up. Have you been able to find them in any census? Do you have any other info that would help me search? Is Horn/Horne her maiden name?
