Coffee County, formed in 1836 from Bedford, Franklin, and Warren counties and name for Tennessee state militia General John Coffee, has a total area of about 435 square miles. From 1850 to 1920, the county's population more than doubled from about 8,000 to over 17,000. Sites like Granny Hickerson Cemetery and Rutledge Falls about five miles southwest of Manchester preserve the landscape of this earlier time.
