There has been some controversy about the two earliest drafts of the Address. Lincoln's son, Robert Todd Lincoln, made Nicolay and Hay the legal guardians of Lincoln's papers in 1874. The Nicolay Copy appeared as a copy in an article written by Nicolay in 1894. After that, it was thought to be among the papers passed to Hay by Nicolay's daughter Helen when Nicolay died in 1901. Robert Lincoln began a search for the first copy in 1908. He discovered a handwritten copy of the Gettysburg Address among the papers of John Hay—a copy now known as the "Hay Draft".
