A descendant of an old Long Island family, he was born at the family mansion on the Fort Neck estate in South Oyster Bay, New York (then Queens, now Nassau County). He was the eldest son of Brig.-Gen. Thomas Floyd-Jones (1788–1851) and Cornelia Haring (Jones) Floyd-Jones (1796–1839). Among his siblings were merchant William Floyd-Jones, Assemblyman Elbert Floyd-Jones, and Sarah Maria Floyd-Jones (wife of Coleman Williams).[1]
His paternal grandparents were David Richard Floyd-Jones and Sarah (Onderdonk) Floyd-Jones and his maternal grandfather was Maj. William Jones. Among his extended family was his uncle, New York State Senator Henry Floyd-Jones, and first cousin, Col. DeLancey Floyd-Jones. He was a descendant of William Floyd, signer of the Declaration of Independence, and Maj. Thomas Jones who owned what is known today as Jones Beach.
He was educated at Christ Church Academy in Manhasset, and graduated from Union College in 1832.
After studying law in Schenectady with Judge Samuel W. Jones, he was admitted to the bar and began practicing law in New York City in 1835 in partnership with James P. Howard. He was a Democratic member of the New York State Assembly (New York Co.) in 1841, 1842 and 1843.
