Sir William Courtenay, 2nd Baronet

Sir William Courtenay, 2nd Baronet (11 March 1676 – 6 October 1735) of Powderham Castle, Powderham,Devon, was an English landowner, a leading member of the Devonshire gentry and Tory politician who sat in the English House of Commons from 1701 to 1707 and in the British House of Commons almost continually from 1707 to 1735.

Courtenay was the son of Colonel Francis Courtenay, MP for Devonshire from 1689 to 1699, and his wife Mary Boevey, daughter of William Boevey (died 1661), of Flaxley Abbey, Gloucestershire.The Boevey family was of Netherlandish Huguenot descent. Mary's brother was John Boevey (died 1706) who refers to himself in his will dated 6 March 1703as "John Boevey of Powderham Castle". Courtenay's father died in 1699, predeceasing his own father Sir William Courtenay, 1st Baronet. Courtenay succeeded his grandfather in 1702 to the baronetcy and the estate of Powderham Castle. He married Lady Anne Bertie, daughter of James Bertie, 1st Earl of Abingdon on 13 July 1704.

Courtenay first stood for Parliament at Honiton at the first general election of 1701. He was defeated, but was then returned unopposed for Devonshire at the second general election of 1701. He was returned again unopposed in the general elections of 1702, 1705, and 1708. He was a moderate Tory, but opposed the impeachment of Dr. Sacheverell in 1710. He stood down at the 1710 general election in favour of Sir William Pole, but when Pole had to submit to re-election on appointment to office, Courtenay was pressured by popular demand to stand again. He defeated Pole by a massive majority at the by-election on 22 July 1712. He was returned unopposed at the 1713 general election. From 1714 to 1716 he served as Lord Lieutenant of Devon. He was returned as a Tory at the 1715 general election and was returned unopposed again at the succeeding general elections in 1722, 1727 and 1734.

Courtenay died on 6 October 1735. He directed his body to be buried in the north aisle of Powderham Church "near the monument there erected". He further desired "my executor (who was his nephew William Courtenay (died 1735) of Powderham)...to bestow and lay out the summe of fifty pounds in erecting a monument near the place of interrment in such manner as my executor shall think fit". No such monument survives. His children included:

• William Courtenay, 1st Viscount Courtenay
• Henry Reginald Courtenay, MP.
• Eleanor Courtenay (died 1765) who married John Francis Basset (1714–1757) MP for Barnstaple in 1740–1741, of Heanton Court, Heanton Punchardon.

He left £10 each to his nieces Elizabeth, Mary, Lucy and Isabella Courtenay for mourning clothes. He also bequeathed them each the sum of £30 to buy a diamond ring each to be worn in his memory. He bequeathed to Sir William Courtenay his nephew the sum of £100 and also made him his residuary beneficiary.

In 1831 Courtenay was recognised as having been de jure 6th Earl of Devon.
