Reverend Ichabod Wiswall (1637–1700) was the third pastor of the church in Duxbury, Plymouth Colony, British America.
Wiswall left Harvard in 1657, after only three years, thereby forfeiting the honor of being able to claim himself as an alumnus of that institution.
Beginning on 7 March 1656, Wiswall served for at least three years as a teacher in the public school at Dorchester.
and later in the ongoing fisheries enterprise of the late Ferdinando Gorges off the coast of Arrowic, Maine where he met his bride.
There he encountered Reverend Increase Mather, a fellow resident of Dorchester, but one who favored a charter which united the Massachusetts Bay and Plymouth colonies.
