The Marsh family probably came from the early settlers of this name in Massachusetts. Lieutenant Alexander Marsh came from England and settled in Braintree, Massachusetts, before May 3, 1654, when he was admitted a freeman of the colony. He owned a house and land in Boston. He died March 7, 1698, aged seventy.
George Marsh was a proprietor of Hingham as early as 1635 and was admitted a freeman, March 3, X635-36, and was later a town officer. He died July 2, 1647.
John Marsh, a shoemaker by trade, came from England to Salem, Massachusetts, in the ship "Mary and John," sailing May 24, 1633. He died in 1674 and his descendants have been numerous. Another Marsh family located at Hartford, Connecticut. The relationship of these pioneers is not known. From these immigrants practically all the American Marsh families are descended, however.
During the revolution the family was well represented in the American army throughout New England and in New York. In 1790, when the first federal census was taken, the family was widely scattered and numerous. Stephen, Samuel and John Marsh were heads of families in Montgomery county. Samuel, Asa and John Marsh were heads of families living in 1790 at Whitestown, New York.
Lewis Marsh, a native of Oswegatchie, St. Lawrence county, New York, was a descendant doubtless of the early settlers of Montgomery county. Children: William, Oscar, Henry, Lester, Hiram, Frederick and Mary.
