Henry Middleton was born in 1717 on the family plantation, "The Oaks", near Charleston, Province of South Carolina. He was the second son of Susan Middleton and Arthur Middleton, a wealthy planter who had served as an acting governor of South Carolina. His grandfather, Edward Middleton, emigrated from England via Barbados. Henry was educated in England before returning to South Carolina to inherit his father's plantation. He became one of the largest landowners in the colony, owning and about 800 slaves.
Public career
Middleton served in a variety of public offices in South Carolina. He was a justice of the peace and a member of the Commons House of Assembly, where he was elected speaker in 1747, 1754, and 1755. He was a member of provincial council, but resigned in 1770 in opposition to British policy. In 1774, at the outset of the American Revolution, Middleton was selected as a delegate to the Continental Congress. He served as that body's president during the last few days of the First Continental Congress, following the departure of Peyton Randolph. Middleton opposed declaring independence from Great Britain, and resigned from the Second Continental Congress in February 1776 when more radical delegates began pushing for independence. He was succeeded in Congress by his son, Arthur Middleton, who was more radical than his father and became a signer of the Declaration of Independence. After Middleton's return to South Carolina, he was elected president of the provincial congress and, beginning on November 16, 1775, served on the council of safety. In 1776, he and his son Arthur helped frame a temporary state constitution. In 1779, he became a state senator in the new government. When Charleston was captured by the British in 1780, Middleton accepted defeat and status as a British subject. This reversal apparently did not damage his reputation in the long run, due to his previous support of the Revolution, and he did not suffer the fate of having his estates confiscated, as many Loyalists did after the war.
Personal life
In 1741, Middleton was married to Mary Baker Williams, the daughter of John Williams, an early South Carolina planter who began building what is today known as Middleton Place around 1730. Together, Henry and Mary were the parents of five sons and seven daughters, only seven of whom survived to adulthood, including:
His grandson, also named Henry, had a long career in politics. He was Governor of South Carolina, U.S. Representative, and the minister to Russia. Henry had fourteen children, including Williams Middleton and Edward Middleton.
