This is an Email sent from the manager of Stanley-Whitman museum house: 

To recap deaths in the house, which you asked about before: Susannah Whitman (wife of the second resident of the house) must have died here in 1772. Following her death, her husband remarried a wealthy widow and moved out of this house into her farmhouse. Before that, two of the Smith children likely died here--sometime between 1725 and 1735 when the Smith family lived in his house. There may have been others, but those are the ones we know about.

There have been numerous unexplained experiences here--usually when someone is working here alone late at night or early in the morning. Last Fall, one staff member heard a woman singing in the kitchen of the historic house late  one night. Independently (without knowing about the previous night) another staff member reported the same singing early the following morning. Some people have heard footsteps in the house. There have been repeated incidents of someone whistling in the afternoons when someone was here alone. The woman whose desk is nearest the door which leads from our office into the historic house consistently feels like she is being watched. And the person who does our cleaning early in the morning thought he saw a small child in historic clothing peering out what would have been the window in my desk area on his way in one morning. Sometimes doors and drawers we remember shutting will spontaneously open as well.
