Looking for Turner of Louisiana

My grandmother is Minnie Walker, maiden TURNER. She was born in 1917 in Louisiana. Her parents were Tom Turner and Clarra Turner, maiden MARTIN, both born in Louisiana. Tom Turner's parents were Tom and Modena, maiden not known. Clarra MARTIN's father's name Wesley MARTIN and her mother was Casey MARTIN. My grandmother doesn't know much about her grandparents, and I would like to find some information on them. I would like to share it with her while I am still able to. Also, it would benefit the rest of my family to get to know our relatives.
