My great grandmother was Louvenia Sprouse. She lived in Liberty County with her husband Charles Miller. She was from Slabtown Louisiana (no longer exists) in Vernon Parish. I haven't any idea if she had any siblings or not. And the census records for the time she would have been in LA were destroyed in a fire.
I am sorry I can't be of any real help to you, but thought with the location similarities, there might be a connection you could go on. Good luck!
