William Floyd was born on December 17, 1734, on Long Island, New York, the second of nine children. His father, a successful farmer of Welsh descent, raised the family with a strong work ethic and practical education. When Floyd’s parents died in 1755, he inherited the family estate and took responsibility for his siblings. He married in 1760 and managed both the farm and family.

Floyd became a respected figure in his community and helped lead the local militia, attaining the rank of Colonel in 1775. He supported the Patriot cause early, attending meetings opposing the British closure of the Port of Boston.

In 1774, Floyd was chosen to represent Suffolk County in the Continental Congress, where he served until 1777 and again from 1779 to 1783. During the war, he also held the rank of Major General in the militia.

While Floyd served in Congress, the British occupied his home, converting it into a barracks. He fled to Connecticut with his wife and three children. The hardships of war took a toll on his family; his wife died in 1781 after prolonged illness and stress.

After the war, Floyd served several terms in the New York State Senate, supported the U.S. Constitution, and participated in the New York Constitutional Convention of 1801. He was elected to the First U.S. Congress, serving from 1789 to 1791.

In later life, Floyd invested in land in central New York, securing a state grant of over 10,000 acres. He spent summers developing the property and eventually relocated there, building a home near present-day Westerville, New York. He died in 1821 at the age of 86.
