Seeing as it's the only preserved and intact family home from the 19th century in all of New York City, it makes sense that this house has also been the source and subject of many ghost stories. The Tredwell family lived here for over 100 years, and the last family occupant was Gertrude, the youngest daughter, who died in the home in 1933. Staff, visitors, and even passerby say they experience weird, disembodied things here.
Don't buy it? Take a candlelit ghost tour of the museum to decide for yourself. And even if you don't catch an apparition out the corner of your eye or hear children playing and floorboards in empty rooms, you'll at least get the sense that you're intruding on someone else's space, in a completely different time, since it's virtually the same as was when Gertrude died.
