Vassalboro (originally Vassalborough) is a town in Kennebec County, Maine, United States. The population was 4,340 at the 2010 census. Vassalboro includes the villages of Riverside, Getchell's Corner, North Vassalboro, and East Vassalboro, home to the town library and sports field. Vassalboro is included in the Augusta, Maine, micropolitan New England City and Town Area.
The town of Vassalboro was named for one of the proprietors of the Maine settlement, William Vassal (or Vassall), a descendant of one of the original patentees (and later deputy) of the Massachusetts Bay Colony, and a wealthy merchant who eventually became a controversial Loyalist. Other historians believe the town derives its name from the original Massachusetts proprietor William Vassal himself, who clashed with John Winthrop so frequently that he removed himself to the town of Scituate, where he soon found himself embroiled in ecclesiastical controversy once again, prompting his move after a decade to Barbados, where he died.
On March 2, 1770, William Vassall, one of Vassalboro's early proprietors, conveyed to his niece Mary Prescott of Nova Scotia Lot Number 5 in Vassalboro, one of the so-called "Proprietor's Lots" reserved for the town's founders. Niece Prescott sold the lot nine months later to a citizen of Hallowell.
The William Vassal who conveyed the Proprietor's Lot was likely the same merchant who graduated from Harvard College, served as sheriff of Middlesex County, Massachusetts, but was forced to flee to England at the outbreak of the Revolutionary War. From the safety of his adopted home in Battersea, Surrey, England, following the conclusion of hostilities, Loyalist Vassall sold off the rest of his considerable American holdings.
The Revere House in East Vassalboro was once the home of Alexander Graham Bell. The Vassalboro Historical Society resides in the old school- house near the East Vassalboro China Lake landing. The East Vassalboro Grange hosts the annual library book sale in the fall.
