History

Effingham County was formed in 1831 out of Fayette and Crawford counties. It may have been named after Thomas Howard, 3rd Earl of Effingham, who resigned his commission as general in the British army in 1775, refusing to serve in the war against the Colonies. The name is Anglo-Saxon for “Effa’s house”. New information suggests that the county was named after a surveyor who surveyed the area whose last name was Effingham. There is no written proof that the county was named after Lord Effingham.
