<P> This decision brought on a storm of criticism, principally from the magistrates of Essex County, which was geographically closest to the ongoing dispute . John Endecott was particularly critical, noting that Winthrop had given the French a chance to see the colonial defenses . The 1644 election became a referendum on Winthrop's policy, and he was turned out of office . The Acadian dispute was eventually resolved with d'Aulnay as the victor . In 1646, Winthrop was again in the governor's seat when d'Aulnay appeared in Boston and demanded reparations for damage done by the English volunteers . Winthrop placated the French governor with the gift of a sedan chair, originally given to him by an English privateer . </P> <P> In addition to his responsibilities in the colonial government, Winthrop was a significant property owner . He owned the Ten Hills Farm, as well as land that became the town of Billerica, Governors Island in Boston Harbor (now the site of Logan International Airport), and Prudence Island in Narragansett Bay . He also engaged in the fur trade in partnership with William Pynchon, using the ship Blessing of the Bay . Governors Island was named for him and remained in the Winthrop family until 1808, when it was purchased for the construction of Fort Winthrop . </P> <P> The farm at Ten Hills suffered from poor oversight on Winthrop's part . The steward of the farm made questionable financial deals that caused a cash crisis for Winthrop . The colony insisted on paying him his salary (which he had refused to accept in the past) as well as his expenses while engaged in official duties . Private subscriptions to support him raised about £ 500 and the colony also granted his wife 3,000 acres (12 km) of land . </P> <P> His wife Margaret arrived on the second voyage of the Lyon in 1631, but their baby daughter Anne died during the crossing . Two more children were born to the Winthrops in New England before Margaret died on 14 June 1647 . Winthrop married his fourth wife Martha Rainsborough some time after 20 December 1647 and before the birth of their only child in 1648 . She was the widow of Thomas Coytmore and sister of Thomas and William Rainborowe . Winthrop died of natural causes on 26 March 1649, and is buried in what is now called the King's Chapel Burying Ground in Boston . He was survived by his wife Martha and five sons . </P>
