As a younger son, Maynard received as his patrimony just three houses in St. Swithun’s parish, London, and he lived at Little Easton, his childhood home, until after his marriage in 1633.
In January 1621 Maynard’s elder brother John was elected for Chippenham on the interest of their brother-in-law, Sir Edward Bayntun*. Shortly afterwards, John decided against taking this seat, believing that he had also secured a place at St. Albans, Hertfordshire. Accordingly, Bayntun arranged for Maynard’s name to be inserted on the election indenture instead without the formality of a fresh vote. However, it then emerged that John had not been elected at St. Albans after all, and still needed the Chippenham seat. It was now too late to amend the indenture again, so on 2 Mar. an embarrassed Baytun had to reveal his subterfuge to the committee for privileges. While shocked at this blatant fraud, the committee opted to report to the House that Maynard had been returned as a Member by accident, with Chippenham’s bailiff taking the blame. On 12 Mar. the Commons agreed that the offending return should simply be corrected in John’s favour, whereupon Maynard’s brief and inglorious parliamentary career was terminated.
In the following year Maynard secured a Court of Wards auditorship in reversion, finally taking up this post in 1634. He had recently married the daughter of a wealthy Flemish immigrant, and with the fruits of office he set up house in 1635 at Walthamstow, where he purchased a manor four years later.
At the Restoration Maynard boldly but unsuccessfully reclaimed his auditorship, in the hope of sharing in the compensation awarded by Parliament to former Wards officials.
