There is a White Plains area in Engelhard, NC where I came from…update 6

…this is close to where Joseph Montier Hall came from, married to Julia Selby both who suffered from mental illness of what type I cannot say, I am guessing some sort of psychosis.

White Plains is also in Pennsylvania, and how I located the Lackawanna Valley story.   The American Civil War was in 1865 - “these people won’t know what’s hit’m”, Kay’s thoughts are that someone let some of these people out of the asylums to fight in the war.   I think this is how they learned that the death of the body will release the soul back to those to who they are connected, or possibly before this.  Then the North looted the banks of the South.

This likely gave birth to the television that operates in a similar manner.

1792.   The New York Hospital opened a ward for "curable" insane patients. In 1808, a free-standing medical facility was built nearby for the humane treatment of the mentally ill, and in 1821 a larger facility called the Bloomingdale Asylum was built in what is now the Upper West Side. In 1894, it was moved further away, to the suburb of White Plains and is currently under operation as the Payne-Whitney Westchester Hospital, a Division of the New York Hospital-Cornell Weill Medical Center.
