Margaret Faunce of Dartmouth, MA

Margaret Faunce married Jacob Sherman 3 March 1738 at Dartmouth, MA.So she was born about 1718.I am trying to connect her to the rest of the Faunce family.She is not in the Faunce genealogy.Does anyone have information about any Faunce family living at Dartmouth, MA in the early 1700's?
