Families began to settle Plymouth circa 1794. The town was formed from the town of Norwich on April 7, 1806. Plymouth was also referred to as Frenchtown, Frank Town, or Francistown in honor of its early French inhabitants. In 1799, South Plymouth was settled by Ebenezer and Patience Frink, giving it the name Frinkville. John Young, the father of Brigham Young, lived in a cabin in the area; an abandoned saw mill sits there now.
