Twenty-four U.S. counties are named Lincoln, according to e-Reference Desk; 16 are named after the 16th President Abraham Lincoln. Maine is one of seven not named after the “Great Emancipator.”

Of the seven Lincoln counties not named after the president, five are named after Major Gen. Benjamin Lincoln, who fought in the American Revolutionary War. The Massachusetts native commanded the Southern Department of the Continental Army and received the official British sword of surrender at Yorktown, e-Reference Desk states. 

The counties named after Major Gen. Lincoln are in Georgia, Kentucky, Missouri, North Carolina and Tennessee, according to www.constitutioncenter.org; two counties are not named for either the president or general. The website states Lincoln County, Maine was founded by the Massachusetts General Court from a portion of York County, Massachusetts in 1760; Maine’s Lincoln County was named after Lincoln, England by Provincial Governor Thomas Pownall.

At its founding, Lincoln County, Maine accounted for three-fifths of the state's land, and stretched east to Nova Scotia.

According to e-Reference Desk, the South Dakotan county’s name stems from Wilmont W. Brookings’ suggestion to name the county after his birth place in Lincoln County, Maine.

The holiday changed to Presidents Day in 1971, with the Uniform Monday Holiday Act to create more three-day weekends.  Currently, a Lincoln Birthday holiday is celebrated unofficially nationwide. It falls on Monday, Feb. 21 this year.   A few states observe Lincoln’s actual birth date. Washington, D.C. holds a ceremony at the Lincoln Memorial, where a wreath is laid.
