Is this the farm house outside of Harper's Ferry where John Brown launched his famous raid? Not sure of its current name - even though I have been there! Is it called the Kennedy Farm? I believe that it is in Maryland, just across the border from WV.
I was going to say Hilltop House, but it is chiefly of brick construction (which doesn't show in your photo), so my next guess will be the Guest House for the NPS. It is supposed to be the most haunted place in Harpers Ferry. Is Isaac Smith (aka John Brown) supposed to have a tie to this place - or is haunted the key?
AKA Isaac Smith was just to narrow it down to Harpers Ferry. John Brown has nothing to do with it. It's not supposed to be haunted by anyone in particular, that was just a small clue. The house now has a very familiar name.
