So in 1868, Abraham Lincoln leaves the white house aged 59 and lets say he lives to be 70 (average age for that period) that gives him 11 years after office to spend in retirement.
He would travel Europe being welcomed as a hero in many capitals by monarchs, including Queen Victoria in London, and would visit Jerusalem to see the "Wailing Wall" and participated in a Friday night services, at the Hurva synagogue.
While traveling he would write his memoirs and advice to President Andrew Johnson during both his terms.
When in 1876, his failing health and the severity of Mary's migraine headaches and other illnesses, they both settle down in Springfield, Illinois setting up the Ellsworth County in honour of Elmer E. Ellsworth, Ellsworth was only 5' 6" tall, but Lincoln called Ellsworth "the greatest little man I ever met."
Lincoln would die a year later while, Todd lives for another 3 years, morning the loss of her husband and 3 sons, but being cared for by a group of nurses from Illinois who are paid for under Lincoln's will.
