Stukely Westcott was one of the founding settlers of the Colony of Rhode Island and Providence Plantations and one of the original members of the first Baptist Church in America, established by Roger Williams in 1638. He came to New England from the town of Yeovil in Somerset, England and first settled in Salem in the Massachusetts Bay Colony, but difficulties with the authorities prompted him to join Roger Williams in settling near the Narragansett Bay in 1638 at Providence Plantations. He remained there for a few years, but he was recorded as an inhabitant of Warwick in 1648, probably having settled there several years earlier. He was most active in colonial affairs from 1650 to 1660 when he was a commissioner, surveyor of highways, and the keeper of a house of entertainment. His highest offices were as an Assistant in 1653 and much later as a deputy to the General Court in 1671 when he was almost 80 years old. He made his will on January 12, 1677, but died the same day with it unsigned, leaving his affairs in limbo for the following two decades.

William Arnold was one of the founding settlers of the Colony of Rhode Island and Providence Plantations, and he and his sons were among the wealthiest people in the colony. He was raised and educated in England where he was the warden of St. Mary's, the parish church of Ilchester in southeastern Somerset. He immigrated to New England with family and associates in 1635. He initially settled in Hingham in the Massachusetts Bay Colony, but he soon relocated to the new settlement of Providence Plantation with Roger Williams. He was one of the 13 original proprietors of Providence, appearing on the deed signed by Roger Williams in 1638, and was one of the 12 founding members of the first Baptist church to be established in America.
