Backhouse’s father, a London alderman of Cumberland origin, received a confirmation of arms in 1574 as one ‘whose ancestors long time past did come out of Lancashire, where they were of worshipful degree’.
It was perhaps encouraged by this success that Backhouse entered Parliament in 1604, sitting for Windsor. His many kinsmen in the House included his brothers-in-law Sir William Borlase and Nicholas Fuller. Over the course of the Parliament he made no recorded speeches, but was named to 50 committees. In the opening session, in which he was nominated to nine committees, his first appointments, on 5 May 1604, were to consider bills on land titles and (with Fuller) Exchequer abuses. Along with Fuller and Borlase, Backhouse was instructed to attend the conference with the Lords of 8 May on purveyance, at which he and Borlase were among those singled out as fitted by their own or their neighbours’ experience to ‘make more pregnant proof’.
In the second session Backhouse was named to ten committees, including those for bills on London housing (24 Jan. 1606) and the bringing of water to London from the Lea (31 Jan.), which measure was subsequently reported to the House by Fuller. It may have been at this committee that Backhouse first came into contact with Hugh Myddelton, with whom, on the matter of the Lea water scheme, he was to have later dealings. On 30 Jan. 1606 he, Fuller and Borlase were appointed to help consider Sir Robert Johnson’s bill to compound for purveyance. His attitude towards this proposal is unknown, but Fuller at least opposed the bill, arguing that ‘composition, in [a] few years, may become an imposition’. Required to attend joint conferences on supply (14 Feb. 1606) and ecclesiastical grievances (11 Apr.), Backhouse was among those ordered to help deliver the Commons’ petition of grievances to the king on 14 May.
Shortly before the beginning of the third session Backhouse found himself in Chancery as a co-defendant in a case prosecuted on behalf of Henry Campion* by the Speaker of the Commons, Sir Edward Phelips.
In the following autumn Carleton reported after a visit to Swallowfield that Backhouse was ‘not a little perplexed’ at the failure of a proposed marriage between his son and one of Neville’s daughters. However, there was no lasting break, for in the following year Backhouse acted as godfather to a Neville child.
Backhouse took the Aylesbury seat formerly held by his brother-in-law Borlase in the Addled Parliament. He was named to nine committees, but appears to have remained a silent Member. On 8 Apr. 1614 he was among those ordered to search for precedents regarding the eligibility for membership of the House of the attorney-general. He was also one of those appointed to consider the repeal of ‘obsolete, unprofitable and pernicious statutes’. He was also named to consider bills to improve Sabbath observance, confirm the Charterhouse hospital, repeal an Elizabethan Act on fish-packing, and prevent customs extortions.
Some four years after the Parliament, Backhouse became engaged in a violent quarrel over his family’s possession of certain pews in Swallowfield parish church, which ended in Star Chamber.
