Mayhew belonged to a family who had established themselves in eastern Essex and southern Suffolk by the early eighteenth century. He was descended from Augustine Mayhew (1622-93), an attorney and lord of the manors of Great and Little Coggeshall. Another of his ancestors was William Mayhew (?1736-87), of Colchester, a barrister and a bencher of Gray’s Inn, high steward and recorder of Colchester and recorder of Ipswich and Aldeburgh, who died without legitimate issue.
The Mayhews plumped for the ministerialist sitting Member standing on the True Blue corporation interest at the 1820 general election in Colchester.
There was a time when I was against reform. I allude to that reform which was advocated when Mr. [Henry] Hunt* was lord of the ascendant. I have all along thought that some reform must take place, and the plan of reform brought forward by ministers is an exceedingly good one ... I think, however, that the clause which takes away the franchise of the present burgesses ought not to stand in its present form ... He could not vote for the measure as it now stood without first endeavouring to maintain the rights of all the freemen. He did not think the independent out-voters should be disfranchised.
He resisted pressure to pledge himself to support the bill without reserve, arguing that disfranchisement of non-resident freemen was ‘little short of a robbery’; but he gave an assurance that he ‘would not endanger the bill by persevering in his opposition to the objectionable clause’. The corporation, whom he accused on the hustings of corruption and misappropriation of municipal revenues, vindictively put up an absentee candidate against him and challenged his qualification. After an eight-day poll, which further drained his resources, Mayhew, whose brother died during the election, was comfortably returned. He proclaimed himself ‘the friend of the people, not only from principle, but because he prided himself in belonging to the middle class’.
At the subsequent general election enthusiasm for reform temporarily masked the differences between Mayhew and Harvey and their supporters and produced an uneasy coalition which enabled them to defeat the corporation nominee. As well as reiterating his support for the bill, on the same terms as before, Mayhew renewed his attack on corporation ‘corruption’.
Nothing has been discovered of his subsequent life until he was declared bankrupt on 9 Jan. 1843, when he had an address at 2 De Crespigny Place, Camberwell, Surrey, as well as that of his business in Crutched Friars. A second and final dividend of one halfpence in the pound was declared on 15 Feb. 1844.
