As solicitor to the Treasury Sharpe was at the centre of Government business; he also carried on ‘a vigorous private practice, much of it among West Indian merchants and planters’;
Sharpe seems to have had some connexion with the Walpole family; possibly also with John Scrope, Walpole’s secretary to the Treasury; but the origin of either is unascertained. In 1754 he was returned for Callington by the Dowager Lady Orford, together with her second husband, Sewallis Shirley. When early in 1756 a separation was being arranged between her and her husband, she, writing to Sharpe from Italy, addressed him as her ‘dear friend’, whose absence often made her ‘melancholy in the midst of the most agreeable company’, and for whom she had ‘the greatest esteem joined to the sincerest friendship and the highest obligations’.
He died 22 Oct. 1756, aged 56, leaving his widow, besides the house in Lincoln’s Inn Fields and that at East Barnet for life, a yearly income of £700; a portion of £10,000 to his daughter who was about to marry the only surviving son of John Craster; his son, Fane William Sharpe, was residuary legatee.
