Louisiana didn't start to records births until the early 1900's so you won't be able to confirm her birth unless you can find her baptism records.
Louisiana didn't start to record deaths until July 1914.
I'd contact the Central Louisiana Genealogical Society, www.rootsweb.ancestry.com/~laclgs/
and ask if they have a local death index, indexed newspaper death notices and inventoried cemeteries in Avoyelles Parish. Successful Searching!
