Lena is an unincorporated community in Miami County, in the U.S. state of Ohio. [1]
Lena was originally called Elizabethtown, and under the latter name was laid out in 1830, and named for Elizabeth Robbins, the wife of a first settler. [2] Another former variant name was Allen's, after Sylvanus Allen, a local postmaster. [2] A post office called Allens was established in 1830, the name was changed to Lena in 1883, and the post office closed in 1914. [3]
