A man of obscure origins who married an heiress from Hertfordshire, Brocket was possibly the son of a namesake from Yorkshire,
While it is possible that the Exchequer official was the MP of 1435, it seems safe to assume that the subject of this biography was his younger namesake, who had formed a connexion with Hertfordshire through marriage. Almost certainly a lawyer, given his service as a j.p. and justice of gaol delivery, the younger Thomas began his public career in the Commons and it was to his time as an MP that he owed his first recorded commission. In early 1436 he, his fellow knight of the shire, Nicholas Morley*, and others were appointed to assess the residents of Hertfordshire for the tax which the Parliament had granted the King, and for the purposes of the tax he himself was found to enjoy an income of £40 p.a. in lands and fees.
The Moseley share of the Fitzsymond inheritance featured in one of the Chancery cases to which Brocket was a party in his later years. Two of these cases, dating from the late 1460s or early 1470s, arose from a couple of bills filed by Thomas Rogers, the son-in-law of the late Edmund Bardolf*, whom Brocket had served as a feoffee. Rogers claimed that Brocket and other Bardolf feoffees had denied him full payment of his wife’s marriage portion and breached their trust regarding other conditions of the settlement drawn up before the marriage took place. In the same period, Bardolf’s grandson and namesake sued Brocket and the other feoffees for refusing him seisin of a manor at Watton-at-Stone.
By then Elizabeth Brocket was no longer alive, for she herself had died on the previous 12 Jan. She had not borne her late husband any surviving children, and Brocket’s heir was his younger brother, Edward. The latter succeeded to the holdings at Bishop’s Hatfield, Sandridge and Ippollitts, as well as Herons, Brocket’s purchased manor at Wheathampstead, indicating that Elizabeth must have consented to a settlement by which these former Fitzsymond properties passed to her brother-in-law and his heirs and remained in the Brocket family.
