4. Woodrow and Edith Wilson
Each having had his or her previous spouse die, two met in 1915, after Woodrow’s Presidency had already begun. Rumors soon began that Woodrow had cheated on his previous wife and that he and Edith had killed his first wife. Edith made the decision that the two should wait until the end of the official year of mourning for Wilson’s previous wife’s death before marriage. When a stroke left Woodrow partly paralyzed, Edith essentially took over the duties of the Presidency, even signing legislation using his hand.
