Sir George Throckmorton of Coughton Court (bef. 1489 – 6 August 1552) was an English politician and a member of Parliament during the reign of Henry VIII. Born by 1489, he was the eldest son of Sir Robert Throckmorton of Coughton Court by Catherine Marrow, daughter of Sir William Marowe or Marrow, Lord Mayor of London.
The Throckmortons took their name from a manor in the parish of Fladbury, Worcestershire, where in the 12th century they were tenants of the Bishop of Worcester. They acquired Coughton, in Warwickshire, by marriage in the early 15th century.
Sir George Throckmorton was born in Worcestershire and was to claim when seeking office there that the greater part of his inheritance lay in that shire, but his father seems to have made Coughton Court the family seat and George was to be the first of his line to sit in Parliament as knight of the shire for Warwickshire; his grandfather had done so for Worcestershire. George's father, Robert Throckmorton, soldier, courtier and Councillor to Henry VII, sent his eldest son to the Middle Temple, which George entered on the same day as a Northamptonshire kinsman, Edmund Knightley; before his death in Italy while on pilgrimage to the Holy Land, Sir Robert had seen his son launched at court and in local government and in enjoyment of numerous leases and stewardships.
This early advancement may have owed something to Throckmorton's marriage to a daughter of another courtier, Sir Nicholas Vaux, whose stepson Sir Thomas Parr, comptroller of the Household to Henry VIII, was the uterine brother of Throckmorton's wife, Katherine. Throckmorton served with his father in the French war of 1513 as captain of the Great New Spaniard. Seven years later he was present at the Field of the Cloth of Gold, which he had been in part devised by his father-in-law. Vaux appointed Throckmorton one of his executors and as such in September 1523 he was commissioned to deliver Guisnes to William, first Baron Sandys of the Vyne.
