I thought Mary Todd Lincoln held seances. I may be wrong. But, I vaguely remember something like that.
Several sources state that she did. She led a tragic life. Much of her family was from the south, and many of her relatives died fighting for the Confederacy. One of her sons, Willie, died at age 11. The Lincolns had his body disinterred twice so they could view his remains again. Of course, she was sitting next to Abraham when he was assassinated. She was also supposed to have had both physical and mental problems.
More than 1 wacko as first lady.
