Roger Ludlow (1590–1664) was an English lawyer, magistrate, military officer, and colonist. He was active in the founding of the Colony of Connecticut, and helped draft laws for it and the nearby Massachusetts Bay Colony. Under his and John Mason's direction, Boston's first fortification, later known as Castle William and then Fort Independence was built on Castle Island in Boston harbor. Frequently at odds with his peers, he eventually also founded Fairfield and Norwalk before leaving New England entirely. After a brief sojourn in Virginia, Ludlow returned to Europe, where he was appointed by a commission distributing seized and forfeited property in the aftermath of Oliver Cromwell's conquest of Ireland. He was also appointed a magistrate administering justice in Dublin, where he is believed to have died. Early life He was born in March 1590 in Dinton, Wiltshire, England. Roger was the second son of Sir Thomas Ludlow of Maiden Bradley, Wiltshire and Jane Pyle, sister of Sir Gabriel Pyle. He matriculated at Balliol College, Oxford in 1609 or 1610, and was admitted to the Honourable Society of the Inner Temple in 1612. Ludlow sailed to America in May 1630 aboard the ship Mary & John with his wife Mary Cogan, a sister-in-law of Governor John Endicott of Massachusetts. They settled at Dorchester, Massachusetts, where they remained for five years. During that period he was chosen magistrate in the Court of Assistants for the Massachusetts Bay Colony. He was elected as Deputy Governor in 1634. During this time Ludlow successfully negotiated the first treaty between the English and the Pequot. In 1635 he was defeated by John Haynes for Governor. Settlement of Connecticut In 1635 Roger Ludlow joined with other Puritans and Congregationalists who were dissatisfied with the rate of Anglican reforms, and sought to establish an ecclesiastical society subject to their own rules and regulations. The Massachusetts General Court granted them permission to settle the cities of Windsor, Wethersfield, and Hartford in the area now known as Connecticut. The Ludlows settled into Windsor. However, ownership of the lands for the new towns along the Connecticut River was called into dispute by the English holders of the Warwick Patent of 1631 that had been granted by Robert Rich, 2nd Earl of Warwick. The Massachusetts General Court established the March Commission to mediate the dispute between the Connecticut colony and the Saybrook Colony, and named Roger Ludlow as its head. The
