Jonesboro is a town in Washington County, incorporated on March 4, 1809. This large tract of land was diminished by ceding land to Jones' Port in 1832, to Columbia and Machias in 1838, and finally to Roque Bluffs in 1891.

Hannah Westin, and her sister, carried 50 pounds of lead through the woods to Machias to support the effort to capture the British vessel Margaretta in 1775.

On the Chandler River, which empties into Englishman Bay, the village is on U.S. Route 1 where is splits to create Route 1A as both reunite at Machias to the northeast.
