Livermore was incorporated in 1795, the northwestern-most town of Androscoggin County. In 1880, the population was 1,262. In 2010, the population was 2,095. Livermore had originally been a grant from the state of Massachusetts to certain people for services in an expedition, which was against Port Royal. The town was named for Deacon Elijah Livermore, a pioneer settler born in Waltham, Massachusetts. The first two settlers of Livermore are known to be Deacon Ellijah Livermore and Major Thomas Fish. Major Thomas Fish had originally been from Worcester County, Oxford, Massachusetts. Major Thomas Fish went to war in 1775, and he was a Major in the Continental Army. Major Thomas Fish had died on December 20, 1781, in Livermore, Maine. Deacon Ellijah Livermore had arrived in 1779, building the first mill near Long Pond in 1782. In 1795 as Livermore familiarized, a county line was established based on the Androscoggin River. The Androscoggin River divides East Livermore and Leeds on the east and southeast. On the south of the river is Turner, on the west side is Canton and Hartford, and on the north side is Jay and Canton. From 1760 to 1805, Livermore had been in Cumberland and Lincoln Counties. In 1805, the town became part of Oxford County. By the act of East Livermore, Livermore was separated from Oxford County and became part of the Kennebec County. On March 1, 1844, the town of East Livermore had been incorporated in the Kennebec County, but by 1854, Livermore, along with Livermore Falls, had joined newly formed Androscoggin County. The county line had determined the east of the river as the Kennebec County, and the west part of the Oxford County. On March 31, 1854, the towns of Turner and Livermore officially set off from Oxford County to the Androscoggin County.
