Lincoln County History

Lincoln was formed on April 7, 1870 from parts of Lawrence, Pike, Franklin, Copiah, and Amite Counties, in the Piney Woods soil area of the southwest part Mississippi.  It was named for Abraham Lincoln (1809-1865, a native of Kentucky,  resident of Illinois, and sixteenth president of the United States.

It is possible that Brookhaven was named for Brookhaven, New York, home of Samuel Jayne, who emigrated to the present site of Old Brook around 1818.  Or it could have been named for the Brooks family, builders of the first house in Brookhaven.
