Gulston came of a younger branch of the Gulstons of Wyddial, Herts. (see Gulston, Richard). He was the ‘head of the first mercantile house in the British factory at Lisbon,’ presumably inherited from his father, who is said never to have been in England. Some time before 1730 he moved to England, accompanied by his widowed sister, who subsequently married John Goddard, her daughter, who married Henry Penton, and a Portuguese friend of the daughter’s, whom he married himself.
Gulston continued to sit for Poole till 1765, when he vacated his seat in favour of his son. He died 16 Aug. 1766.
