Wallis, a man of obscure background, occupied his own residence in Cambridge by 1587.
Elected to his third Parliament as a Cambridge MP in 1604, Wallis’s first committee appointment was to consider a bill concerning the evasion of customs (15 Mar. 1606).
Despite his service in Parliament, Wallis was censured by the corporation in September 1611 for making unjust verbal attacks on the outgoing mayor, Thomas French.
