In the Windsor land inventory on 28 February 1640, John Mason held seven parcels, six of which were granted to him: "a home lot with some additions to it", ; "in the Palisado where his house stands and mead adjoining" ; "in the first mead on the north side of the rivulet, for mead and addition in swamp" ; "in the northwest field for upland" "with some addition on the bank side"; "over the Great River in breadth by the river twenty-six rods more or less, and continues that breadth to the east side of the west marsh, and there it is but sixteen rods in breadth and so continues to the end of the three miles"; "of land by Rocky Hill"; and "by a deed of exchange with Thomas Duy ... on the east side of the Great River in breadth eighteen rods more or less, in length three miles".
