US Army General and Explorer. He was born at "The Thickets" plantation near Darien, McIntosh County, Georgia; where his parents lived from 1795-1800. At age sixteen he joined the regiment commanded by his father during Andrew Jackson's campaigns against the Creek Indians, serving as his father's aide during combat at the battle at Autossee and other actions. He then attended West Point, but was dismissed in 1817, afterwards obtaining a commission as a Lieutenant in the Marines and conducting observation tours in Europe. In 1824 he commanded the honor guard that escorted the Marquis de Lafayette when he arrived in New York City to tour the United States. In the 1830s he returned to Georgia to manage his family's plantations, "Fairfield" and "Bellevue", and became commander of a Georgia Militia brigade with the rank of Brigadier General. During the Seminole campaign of 1838 Floyd and several Georgia Militia units were ordered to federal duty in search of Seminoles hiding in the Okefenokee Swamp, but the mission became an exploration of the then unknown marsh, and his reports to his superiors and newspaper articles publicized the Okefenokee nationwide as a valuable site that should be preserved. In 1839 he was a candidate for Major General and commander of the Georgia Militia, but was not appointed, afterwards returning to his plantations. He also became active in the Georgia Historical Society and other pursuits, including writing poetry and music, painting, gun collecting and boat racing until his death from a sudden illness. His diary is still in print and is a primary resource about the Seminole campaign and exploration of the Okefenokee, and his personal papers are part of the Georgia Historical Society's Floyd Collection. He died at the Bellevue plantation home which rested between the community of Woodbine and the smaller plantation Fairfield.
