Courtenay’s ancestors settled in England during the twelfth century, acquired the earldom of Devon in 1335, and regularly represented that county in the Commons from 1377. Although the peerage became extinct in 1556, and much of the family’s property was dispersed among co-heirs, the residual male line at Powderham remained a major force in Devon society.
Courtenay did not attend university, unlike several of his brothers, and apparently inclined towards a martial career. He served in Ireland prior to June 1600, possibly under his kinsman Lord Mountjoy (Charles Blount†), then turned his hand to privateering, capturing a French ship laden with Spanish goods in 1602. Three years later his elder brother’s death rendered him heir to the family estates, but he played little part in county affairs before the end of the following decade, apart from taking up a militia command.
On 1 Apr. 1624 Sir William made over almost his entire estate to Courtenay and another trustee. Ostensibly this move was intended to ease the payment of his debts, which now stood at more than £10,000, but it may also have been designed to protect his property as, with war with Spain now looming, tougher measures against recusants seemed likely. Indeed, Sir William was presented by John Drake in the Commons as a Catholic office-holder on 27 April. Indicted in the following July at the Devon assizes, Sir William subsequently lost his major local offices again, though he was not actually convicted of recusancy until March 1626.
Despite these disadvantageous circumstances, Courtenay successfully stood as a Devon knight of the shire in 1625, displacing his father’s nemesis, Drake, who had represented the county in the three previous parliaments. His election was effectively a personal endorsement by the Devon establishment, offsetting Sir William’s disgrace, and perhaps also an acknowledgement of his new role in managing his family estates. However, beyond this symbolic triumph, Courtenay achieved little in the Commons, being named to just one bill committee, concerning the punishment of petty larceny (25 June).
In 1627 Courtenay persuaded the Crown that as he himself conformed, those lands transferred to him before his father’s indictment were not liable to recusancy fines.
Courtenay reportedly went blind in later life.
