Elma was the last town formed in the county. When the time came to put up a post office for the local lumber mill, a resident suggested it be named after a famous large American elm, then growing at the corner of the modern Clinton and Bowen Road. The name was accepted, and after all procedures were carried out, the new Elma Post Office was established in 1852 and began receiving mail three times a week. The town was officially created in 1857 from parts of the towns of Aurora and Lancaster.
