The Congregational Church of Grafton traces its roots back to a church established in 1671 in what was then known as Hassanamisco Plantation (now Hassanamesit Reservation). In 1731 the body that would become known as the Congregational Church of Grafton was gathered, and four years later the town of Grafton was founded. The collection contains records of vital statistics, church membership, ordination, ecclesiastical councils, church meetings, and correspondence.
