During Thomas Lincoln's lifetime, he and his wife were not invited to Abraham's wedding and never met Abraham's wife or children. David Herbert Donald stated in his book "Lincoln" that "In all his published writings, and indeed, even in reports of hundreds of stories and conversations, he had not one favorable word to say about his father." Abraham, did, however, name his fourth son Thomas, the choice of which, Donald speculates, "suggested that Abraham Lincoln's memories of his father were not all unpleasant – and perhaps hinted at guilt for not having attended his funeral."
