Lewis Morris (April 8, 1726–January 22, 1798) was an American landowner and developer from Morrisania, New York. He was born at the manor of Morrisania. He signed the U.S. Declaration of Independence as a delegate to the Continental Congress for New York.
This Morris was the third to be named Lewis, and was born on the family estate of Morrisania. He was the son of Lewis and Katrintje or Catherine (Staats) Moris. His great grandfather (Richard, died 1672) had immigrated to New York through Barbados after being part of Oliver Cromwell's army in the English Civil War of 1648. He purchased the first tract of land in The Bronx that became the basis for the Morrisania manor. When Richard and his young wife died, leaving behind an infant son named Lewis, it was Richard's brother, Colonel Lewis Morris, also of Barbados, who came to Morrisania to help manage the estate formerly belonging to his late-brother and now his infant nephew. Eventually the infant Lewis Morris (1671-1746) inherited the estate of his father after the death of his uncle, Col. Lewis Morris, and his wife, who were childless. This Lewis Morris married a woman named Isabella and then expanded and patented the estate and was also Governor of New Jersey.
When his father died in 1762, he inherited the bulk of the estate. A prominent land owner in colonial New York, Lewis was appointed as a judge of the Admiralty Court for the province in 1760. As the Revolution drew near, he resigned this post in 1774. He was elected to the Colonial Assembly in 1769.
