Nobody can answer what this movie is!?

Ive asked this before with no success, but maybe I will get lucky. The movie starts off in the swamps, either Louisiana or Florida probably. A boat is pulling up to a dock and an old man is waiting and a pretty young girl sees him and yells Pa Pa and runs and hugs him. She has a weird name like Napees or something. Her dad is white but she is half native american. Her mother died. They live out in the swamp in a log cabin and she complains how she hates that her dad sent her into town for school, that she likes to be home with him.

Later 2 men attack and kill her father and I think she walks in as they are leaving and sees them but she manages to escape. She winds up with a young man that was her fathers friend protecting her as the two killers are looking for her cause she is a witness.

I saw this movie years ago so this description might be a little off. Its probably a late 80,s to early 90,s movie.
