horror movie from 00’s where a kid goes missing after family moves to countryside

I’m not sure everything I remember is correct. A family moves into a house near the woods and some rednecks start to scare them by putting pigs’ heads on stakes. A child (I think it was a girl) disappears and the ghost of a previous victim helps the parents find the place where she is. I think the movie was in english, and I watched it around 2008.
