The girl's parents researched the imaginary friend's name, Mrs Woodman, along with another name they'd heard from their daughter, Gridley. They discovered that a real Jane Gridley Woodman had lived in their house at the turn of the Twentieth Century. The little girl's Mrs. Woodman had seven children, as had Jane, with the same number of boys and of girls as Jane's children.
The visits lasted for years. At some point, the apparition began to ask the little girl for a favor. It was just a hint at first, but Mrs Woodman became more and more insistent as time went on.
The article links to current video from a regional mainstream news station. The blogger then addresses some of the unreported issues, especially "How could a child know those things?" There are other issues, however, like electrical and electronic phenomena. As demonstrated in the video, the news crew itself experienced technical problems in the "hot" area of the house. There is also an indication that some earlier residents of the house saw Mrs Woodman independently of the family who lives there now.
