Experience Mayhew (1673–1758) was a New England missionary to the Wampanoag Indians on Martha's Vineyard and adjacent islands. He is the author of Massachusett Psalter (a rare book like the Bay Psalm Book and Eliot Indian Bible). He married Thankful, daughter of Thomas Hinckley, Governor of Plymouth Colony. In 1717, he translated the Lord's Prayer into Mohegan-Pequot. Mayhew published Indian Converts in 1727, which covers the lives and culture of four generations of Wampanoag men, women, and children on Martha's Vineyard. Mayhew is also the author of the sermon Grace Defended.
