Suspenseful scary movie. Can't remember the name of it. Help me out?

It's older, but not too old. All I remember of it was there was a girl who trusted her parents or something, but they were really killing children for like superstitious witchcraft reasons and their daughter was like the twelfth child or thirteenth or something and they were going to kill her. And all the dead kids were trying to warn her. It was like a suspense/scary movie. There was a scene in it where all the dead kids were in the dining room and the house was really dark. I saw it when I was younger and can't remember the name or find it anywhere. Help me out?
