Question: Whose brother-in-law was banished from the Massachusetts Bay Colony during the Antinomian Controversy?
Context: Nicholas Easton ( 1593–1675) was an early colonial President and Governor of Rhode Island.  Born in Hampshire, England, he lived in the towns of Lymington and Romsey before immigrating to New England with his two sons in 1634.  Once in the New World, he lived in the Massachusetts Bay Colony towns of Ipswich, Newbury, and Hampton.  Easton supported the dissident ministers John Wheelwright and Anne Hutchinson during the Antinomian Controversy, and was disarmed in 1637, and then banished from the Massachusetts colony the following year.  Along with many other Hutchinson supporters, he settled in Portsmouth on Aquidneck Island, later a part of the Colony of Rhode Island and Providence Plantations.  He was in Portsmouth for about a year when he and eight others signed an agreement to create a plantation elsewhere on the island, establishing the town of Newport. John Wheelwright (c.1592–1679), was a Puritan clergyman in England and America, and was most noted for being banished from the Massachusetts Bay Colony during the Antinomian Controversy, and for subsequently establishing the town of Exeter, New Hampshire.  Born in Lincolnshire, England, he was raised in a family with substantial means, and received both a B.A. and M.A. at Sidney Sussex College, Cambridge where he was a noted athlete and where Oliver Cromwell was a college friend.  Ordained in 1619, he became the vicar of the church in Bilsby, Lincolnshire, and held this position for ten years until removed for simony. Philip Sherman (1611–1687) was a prominent leader and one of the founding settlers of Portsmouth in the Colony of Rhode Island and Providence Plantations.  Coming from Dedham, Essex in southeastern England, he and several of his siblings and cousins settled in New England.  His first residence was in Roxbury in the Massachusetts Bay Colony where he lived for a few years, but he became interested in the teachings of the dissident ministers John Wheelwright and Anne Hutchinson, and at the conclusion of the Antinomian Controversy he was disarmed and forced to leave the colony.  He went with many followers of Hutchinson to establish the town of Portsmouth on Aquidneck Island, later called Rhode Island.  He became the first secretary of the colony there, and served in many other roles in the town government.  Sherman became a Quaker after settling in the Rhode Island colony, and died at an advanced age, leaving a large progeny. John Easton (1624–1705) was a political leader in the Colony of Rhode Island and Providence Plantations, devoting decades to public service before eventually becoming governor of the colony.  Born in Hampshire, England, he sailed to New England with his widowed father and older brother, settling in Ipswich and Newbury in the Massachusetts Bay Colony.  As a supporter of the dissident ministers John Wheelwright and Anne Hutchinson during the Antinomian Controversy, his father was exiled, and settled in Portsmouth on Aquidneck Island (later called Rhode Island) with many other Hutchinson supporters.  Here there was discord among the leaders of the settlement, and his father followed William Coddington to the south end of the island where they established the town of Newport.  The younger Easton remained in Newport the remainder of his life, where he became involved in civil affairs before the age of 30. Sir Henry Vane (baptised 26 March 1613 – 14 June 1662), son of Henry Vane the Elder (often referred to as Harry Vane to distinguish him from his father), was an English politician, statesman, and colonial governor.  He was briefly present in North America, serving one term as the Governor of the Massachusetts Bay Colony, and supported the creation of Roger Williams' Rhode Island Colony and Harvard College.  A proponent of religious tolerance, he returned to England in 1637 following the Antinomian controversy that led to the banning of Anne Hutchinson from Massachusetts. John Porter was an early colonist in New England and a signer of the Portsmouth Compact, establishing the first government in what became the Colony of Rhode Island and Providence Plantations.  He joined the Roxbury church with his wife Margaret in 1633, but few other records are found of him while in the Massachusetts Bay Colony until he became involved with John Wheelwright and Anne Hutchinson during what is known as the Antinomian Controversy.  He and many others were disarmed for signing a petition in support of Wheelwright and were compelled to leave the colony.  Porter joined a group of more than 20 men in signing the Portsmouth Compact for a new government, and they settled on Rhode Island where they established the town of Portsmouth.  Here Porter became very active in civic affairs, serving on numerous committees over a period of two decades and being elected for several terms as Assistant, Selectman, and Commissioner.  He was named in Rhode Island's Royal Charter of 1663 as one of the ten Assistants to the Governor. Edward Hutchinson (c. 1564 - 1632) was a mercer and a resident of Lincolnshire, England, most noted for the careers of his children in New England.  While his father and several of his uncles and brothers became prominent as clergymen, aldermen, sheriffs, and mayors in the city of Lincoln, Edward focused his efforts on his business after moving to the town of Alford.  Remarkably, not a single record for him has been found in Alford, other than his burial and the baptisms of his 11 children, but he likely gained a considerable estate, and his children married into prominent families.  What was most exceptional about Edward Hutchinson occurred following his 1632 death.  Beginning in 1634, five of his nine surviving children and his widow immigrated to New England, and all six of them were exiled from the Massachusetts Bay Colony as a result of the events of the Antinomian Controversy from 1636 to 1638.  From Boston two of his children went south and became founding settlers of the Colony of Rhode Island and Providence Plantations, and three of them, with his widow, went north to establish Exeter in the Province of New Hampshire, and then proceeded to Wells, Maine.  Because of their involvement in the controversy, his children had a disproportionately large role in the establishment of these new settlements in New England. Anne Hutchinson (née Marbury; July 1591 – August 1643) was a Puritan spiritual adviser, mother of 14, and an important participant in the Antinomian Controversy which shook the infant Massachusetts Bay Colony from 1636 to 1638.  Her strong religious convictions were at odds with the established Puritan clergy in the Boston area, and her popularity and charisma helped create a theological schism that threatened to destroy the Puritans' religious community in New England.  She was eventually tried and convicted, then banished from the colony with many of her supporters. William Wentworth (1616–1697) was a follower of John Wheelwright, and an early settler of New Hampshire.  Coming from Alford in Lincolnshire, he likely came to New England with Wheelwright in 1636, but no records are found of him in Boston.  When Wheelwright was banished from the Massachusetts Bay Colony for his role in the Antinomian Controversy, he established the settlement of Exeter, New Hampshire, and Wentworth followed him there and then to Wells, Maine.  After Wheelwright left Wells for Hampton, New Hampshire, Wentworth went to Dover, New Hampshire, and this is where he lived the remainder of his life.  He was the proprietor of a sawmill, and held several town offices, but is most noted for being an elder in his Dover church for nearly 40 years.  He had 11 children with two wives, and has numerous descendants, including many of great prominence. The Antinomian Controversy, also known as the Free Grace Controversy, was a religious and political conflict in the Massachusetts Bay Colony from 1636 to 1638.  It pitted most of the colony's ministers and magistrates against some adherents of the Free Grace theology of Puritan minister John Cotton.  The most notable Free Grace advocates, often called "Antinomians", were the charismatic Anne Hutchinson, her brother-in-law Reverend John Wheelwright, and the young governor of the colony Henry Vane.  The controversy was a theological debate concerning the "covenant of grace" and "covenant of works".
