Lincoln wrote the following autobiographical sketch for the 1860 Presidential campaign. It was intended to introduce him to the broad swath of the electorate who knew little or nothing about his history and background.

Abraham Lincoln was born Feb. 12, 1809, then in Hardin, now in the more recently formed county of Larue, Kentucky. His father, Thomas, & grand-father, Abraham, were born in Rockingham county, Virginia, whither their ancestors had come from Berks county, Pennsylvania. His lineage has been traced no farther back than this. The family were originally quakers, though in later times they have fallen away from the peculiar habits of that people. The grandfather Abraham, had four brothers – Isaac, Jacob, John & Thomas. So far as known, the descendants of Jacob and John are still in Virginia. Isaac went to a place near where Virginia, North Carolina, and Tennessee, join; and his descendants are in that region. Thomas came to Kentucky, and after many years, died there, whence his descendants went to Missouri. Abraham, grandfather of the subject of this sketch, came to Kentucky, and was killed by indians about the year 1784. He left a widow, three sons and two daughters. The eldest son, Mordecai, remained in Kentucky till late in life, when he removed to Hancock county, Illinois, where soon after he died, and where several of his descendants still reside. The second son, Josiah, removed at an early day to a place on Blue River, now within Harrison county, Indiana; but no recent information of him, or his family, has been obtained. The eldest sister, Mary, married Ralph Crume and some of her descendants are now known to be in Breckenridge county, Kentucky. The second sister, Nancy, married William Brumfield, and her family are not known to have left Kentucky, but there is no recent information from them. Thomas, the youngest son, and father of the present subject, by the early death of his father, and very narrow circumstances of his mother, even in childhood was a wandering laboring boy, and grew up litterally without education. He never did more in the way of writing than to bunglingly sign his own name. Before he was grown, he passed one year as a hired hand with his uncle Isaac on Wataga, a branch of the Holsteen River.
