Mary Todd Lincoln - Wikipedia

Ann Todd Lincoln (December 13, 1818 – July 16, 1882) was the wife of the 16th President of the United States, Abraham Lincoln, and thus First Lady of the United States from 1861 to 1865. She dropped the name Ann after her younger sister, Ann Todd [Clark], was born, and did not use the name Todd after marrying.

Mary Ann was a member of a large, wealthy Kentucky family, and was well educated. After living in the Todd Houseand finishing school during her teens, she moved to Springfield, Illinois, where she lived with her married sister Elizabeth Edwards. Before she married Abraham Lincoln, Mary was courted by his long-time political opponent Stephen A. Douglas. She and Lincoln had four sons together, only one of whom outlived her. Their home of about 17 years still stands at Eighth and Jackson Streets in Springfield, Illinois.

She supported her husband throughout his presidency. She witnessed his fatal shooting when they were together in the President's Box at Ford's Theatre on Tenth Street in Washington.
Mary was involuntarily institutionalized for psychiatric disease ten years after her husband's murder. She also complained of many physical symptoms during her adult life.
