History of Effingham County

Effingham County Illinois 1831
Effingham County when it was first created in 1831

Effingham County was created in 1831. It was formed from parts of Fayette and Crawford counties.

The county might have been named after Thomas Howard, 3rd Earl of Effingham. He was a British general who refused to fight against the American Colonies in 1775. The name "Effingham" comes from an old English word meaning "Effa's house." Some new information suggests it was named after a surveyor named Effingham. However, there is no clear written proof about which "Effingham" the county was named after.
