What is the decades old movie about a big haunted house or castle with a bloodstain on the carpet that would not clean and Something about ghosts being hurt by the paranormal investigation?

Additional notes (if same movie): A family with one son and one daughter moves in, they have nicknamed themselves "Stars" and "Bars" sounds like "house on haunted hill" but that was about a bunch of strangers. no family or "stars n bars". hope this helps...
