In addition to many former presidents, presidents' wives, a black cat, and a British soldier, probably the most widely reported spectre to haunt the White House is Abraham Lincoln (1809-1865).  Many guests of the White House, including Queen Wihelmina of the Netherlands (1880-1962), has reported seeing him in rooms or in the halls.

Not only have ghosts been reported just sitting or walking in the White House, some have been seen hard at work.  Abigail Adams (1880-1962), wife of John Adams (1735-1826), used to do her own laundry, and has been reported hanging her laundry in the East Room to dry just as she did during the time she lived in the White House.
