Henry and his wife Edith Squire along with their eight sons and one daughter, arrived in Braintree in 1638, during the reign of King Charles I. They were "..part of the great Puritan migration, Dissenters from the Church of England who, in the decade following the founding of the Massachusetts Bay Colony in 1630, crossed the North Atlantic intent on making a new City of God, some twenty thousand people, most of whom came as families." Only the seventh and youngest son, Joseph, remained in Braintree.
