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.

Samuel Wilbore was one of the founding settlers of Portsmouth in the Colony of Rhode Island and Providence Plantations. He emigrated from Essex, England to Boston with his wife and three sons in 1633. He and his wife both joined the Boston church, but a theological controversy began to cause dissension in the church and community in 1636, and Wilbore aligned himself with John Wheelwright and Anne Hutchinson, signing a petition in support of dissident minister Wheelwright. In so doing, he and many others were disarmed and dismissed from the Boston church. In March 1638, he was one of 23 individuals who signed a compact to establish a new government, and this group purchased Aquidneck Island, then known as "Rhode Island", from the Narragansett Indians at the urging of Roger Williams, establishing the settlement of Portsmouth.
