Alexander Denton came of an old Buckinghamshire family, who had been seated since 1547 at Hillesden, 3 miles from Buckingham, owning also the Prebend End manor in that borough.
Soon after re-election in 1722 Denton vacated his seat on appointment to a judgeship. He applied unsuccessfully to Walpole in January 1736 to be made lord chief justice of the common pleas and again in February 1737 to be made lord chief justice of the King’s bench (see under Willes, John) but Walpole told him that he was ‘too old and infirm to discharge the duty’. Offered the post of chief baron of the Exchequer in 1738, he at first refused; but ‘when I shewed a willingness to submit ... the objection was made and no time given me to do what [was] required’. ‘My greatest desire is to know why I was so very much pressed to take it and why I was so easily dropped.’
