Ashland is a two township town in Aroostook County, incorporated on February 18, 1862 from the township of T11 R5 WELS. In 1869 its name change to Dalton, then back to Ashland in 1876.
Sheridan plantation was organized on May 21, 1878 from T12 R5 WELS, then annexed by Ashland in 1901 to form its present boundaries.
Lumbering was once the major industry, but that activity peaked early in the 20th century.
The settlement of Sheridan remains near the main community of Ashland, which is at the junction of state routes 11, 163, and 227 east of Mapleton and Presque Isle.
