Researching Saucier of Avoyelles Parish LA

My Maternal great grandmother was Elisia Saucier, b.1863. Her family was allowed to walk to walk through Union forces to safety - probably at the battle of Mansura. Elicia, age about 2, was carried by her mother.

She married Fabien Jeansonne in 1880.

I believe she died in 1935 but have been unable to find burial place or any other death information.
