On November 4, 1842, Abraham Lincoln married Mary Todd, the daughter of Robert Smith Todd and Eliza Parker, prominent citizens of Lexington Kentucky. Abraham and Mary Lincoln remained married until his assassination in 1865. The death of her husband weighed heavily on Mary, as did the deaths of three of her children, and she became increasingly unstable. In 1875, she was committed to an insane asylum by Robert Todd Lincoln, her only surviving child. She died in 1882.
