Richard Mentor Johnson was born in the settlement of Beargrass on the Kentucky frontier (present-day Louisville) on October 17, 1780, the fifth of Robert and Jemima (Suggett) Johnson's 11 children, and the second of eight sons. His brothers John and Henry Johnson survived him. His parents married in 1770. Robert Johnson purchased land in what is now Kentucky, but was then part of Virginia, from Patrick Henry and from James Madison. He had worked as a surveyor and was able to pick out good land. His wife Jemima Suggett "came from a wealthy and politically connected family".
