Challenges to land titles were common in Kentucky’s early years, and the Lincoln family experienced them firsthand. In 1811, Thomas and Nancy Lincoln moved to Knob Creek with their two children, Sarah and Abraham. They leased thirty acres of bottomland along the Old Cumberland Trail, and their third child, Thomas, was born there and died in infancy. Abraham and Sarah attended a local school two miles northeast, where Zachariah Riney and Caleb Hazel gave Abraham his first formal schooling. His classroom education did not last, because the demands of the frontier required him to work on the family farm, though he continued learning by borrowing books and reading them by the fireplace or under a shade tree. In 1815, the Lincolns and nine neighbors became involved in a land title dispute over the entire Knob Creek valley. The next autumn, Thomas Lincoln lost a court case to regain the Sinking Spring farm where Abraham had been born, and he then moved the family to present-day Spencer County, Indiana. Abraham Lincoln later wrote that although he was not born at Knob Creek, it was the place of his earliest recollection.
