DeKalb County was formed in 1822 from parts of Henry, Gwinnett and Fayette counties.  It was the 56th county created in the state.  DeKalb County was named after Baron Johann DeKalb, who accompanied LaFayette to America and served as a major general in the Continental Army. 

The county seat was established in 1823, in the City of Decatur, the oldest town in the county.  It was named in honor of Stephen Decatur, an American Naval officer.  Mills and ginneries were vital to the county’s early growth.  This heritage lives on in the names of various DeKalb roads that once led to these mills such as Browns Mill, Evans Mill and Henderson Mill. The 2006 population estimate for DeKalb County is 677,437 according to the U.S. Census Bureau.
