Let's not forget Turtledove's 19th Century AH novels in which he creates an American Civil War during Breckinridge's presidency. He even went so far to make Abraham Lincoln president. I did a Google search for Lincoln, and only found two hits. One was a short Congressional bio from Lincoln's one term in the House, and the other was a short article about his life as a lawyer in Illinois. How Turltledove could use him as the president is way beyond me. Those AH authors have to be seriously deranged to come up with some of the ideas they do.
