The early death of Fortescue's wife prompted him to become a barrister,[6] and he was admitted to the Middle Temple in 1714, and transferred to the Inner Temple later in the same year before his call to the Bar in July 1715.[4]
As well as his work as a barrister and judge, Fortescue was also involved in the London literary scene, having been introduced by his school friend John Gay to Alexander Pope, and he became a founding member of the Scriblerus Club.[4] He was a co-author with Pope of "Stradling versus Stiles", and Pope dedicated his Imitation of the First Satire of Horace to him.[8]
Marriage and children
On 7 July 1709 he married his cousin, Mary Fortescue (d.1710), daughter of Edmund Fortescue (1660–1734) of East Allington, from a junior branch of the Fortescues of Fallapit in the parish of East Allington,[9] Devon, descended from Sir Henry Fortescue (fl. 1426), Lord Chief Justice of the Common Pleas in Ireland, who had married the heiress of Fallapit.[5] Mary died an early death on 1 August 1710 and her monument exists in St Andrew's Church, East Allington.[10] Mary and William had a daughter, who was their sole heiress:[6]
Mary Fortescue (1710–1752), who inherited the estate of Fallapit from her mother.[10] She married John Spooner and produced an only daughter Mary Fortescue (d.1747) who died an infant.[10]
Death
Fortescue died on 16 December 1749 aged 63 and was buried in the Rolls Chapel in London, where exists his monument.[10]
