 He hoped to receive an appointment to command a spring expedition to North America, but his health suddenly declined, and he died of a stomach ailment on 13 December 1746.Lestock probably married Sarah (d. 1744), of Chigwell Row in Essex during his time on half pay in the early 1720s.They may have had a son, as a boy named Richard Lestock was baptised at Chigwell on 14 July 1723, but if so he presumably died young as no more is heard about him.
