Sir Robert Throckmorton, 4th Baronet

Following the death of his father on 8 March 1720, he succeeded as the 4th Baronet Throckmorton, of Coughton. The Throckmorton baronetcy had been created by King Charles I in gratitude for Sir Robert Throckmorton's support of the monarchy during the English Civil War.^[4]

In 1748, shortly after the marriage of his son George, Sir Robert and his wife Catherine settled at the Buckland estate, which he inherited from his mother's family, the Yates. Sir Robert built a new house at Buckland in 1757 from plans developed by John Wood, the Elder, best known as the architect of Bath. Wood died before the house was built, so his son, John Wood, the Younger completed the Palladian house, known as Buckland House. Sir Robert hired artist Giovanni Battista Cipriani to paint the ceiling of the library in the east pavilion of the house.^[5][6][7]

Sir Robert was married three times. His first marriage was in c. 1721 to Lady Theresa Herbert (1706–1723), daughter of William Herbert, 2nd Marquess of Powis and the former Mary Preston (daughter and co-heir of Sir Thomas Preston, 3rd Baronet of Furness). Before her death in 1723, they were the parents of:^[8]

• Robert Throckmorton, who died unmarried in Paris as a child.^[4]
• George Throckmorton (1721–1767), who married Anne Maria Paston, daughter of William Paston and Mary (née Courtenay) Paston.^[8]
• Mary Teresa Throckmorton (1723–1791), who married Thomas Fitzherbert, son of Thomas Fitzherbert and Constantia (née Southcote) Fitzherbert, in 1743.^[8]

In January 1738, he married Catherine Collingwood (d. 1761), daughter of George Collingwood, of Eslington (who had been executed for his part in the Jacobite rising of 1715). Before her death in 1761, they were the parents of:^[8]

• Barbara Throckmorton (d. 1764), who married Thomas Giffard, 22nd of Chillington, son of Peter Giffard, 20th of Chillington, in 1763.^[8]

In 1763, he married Lucy Heywood at St George Hanover Square. Lucy was a daughter of Mary (née Elton) Heywood (daughter of Sir Abraham Elton, 2nd Baronet of Clevedon Court, MP for Bristol and Taunton)^[9] and James Heywood of Maristow House and Jamaica. Her brother was James Modyford Heywood, MP for Fowey and Lord of the Admiralty.^[10]

He died on 8 December 1791 at age 89 and was buried at Coughton, Warwickshire. As his son predeceased him, he was succeeded in the baronetcy by his grandson, Sir John Throckmorton, 5th Baronet.^[11] His widow Lucy died four years later on 20 November 1795.^[4]
