Location: Dutchess, New York Colony
Territory ceded to New York colony by Connecticut colony.
"Under a new agreement of November 28, 1683 the boundary between Connecticut and New York was generally recognized as a line parallel to and twenty miles from the Hudson River north to the Massachusetts line. However, New York, acknowledging most of Connecticut's settlements in Fairfield County, gave up a claims to a 61,660 acre rectangle east of the Byram River, which became the area sometimes referred to as Connecticut's "panhandle" or the "handle of the cleaver". In return, Connecticut gave up its claims to Rye and ceded to New York a strip of land 580 rods (1.81 miles) wide "equivalent" to the area of the panhandle that extended north from Ridgefield along Westchester, Putnam, and Dutchess Counties in New York to the Massachusetts line. This territory came to be known as "The Oblong". The Oblong has acquired the reputation of being a genealogical "black hole". Some information may be included among records of the 'parent' Connecticut towns and other information may in New York town and/or county records, but some families residing in The Oblong appear to have been missed by both states."
