A mercer of unknown origin, Segryme resided in the parish of St. John Maddermarket.
Customs accounts show that he traded through the port of Great Yarmouth in the early 1450s, exporting woollen cloth and importing a variety of commodities, including felt hats, canvas and paper.
The position of treasurer of the city was Segryme’s first known office after he became a freeman of Norwich in 1426-7,
Although evidently engaged in local politics by the later 1430s, Segryme did not begin to play a leading role in civic affairs until the succeeding decade. In January 1441 he and other citizens were tasked with informing the duke of Norfolk, who had come to Norwich seeking a loan for the King, that the city was so ‘desolate of everything’ that it was unable to raise a notable sum.
The King punished the city by confiscating its liberties for a second time and appointing Clifton its governor. Henstead, Segryme and Aleyn were removed from office but it is unlikely that they fell into complete disgrace, since the two former sheriffs were members of a delegation which Clifton sent to the King at Windsor in the following month.
A few months later, Segryme was elected to his only Parliament. This sat until July 1449, and shortly after its dissolution the Crown commissioned Segryme and Robert Toppe*, with whom he had sat in the Commons, to distribute a tax allowance in Norwich. He subsequently served on at least five other royal commissions, including one of oyer and terminer charged with investigating allegations of trespass, oppression, maintenance and other abuses in Norwich. This was established in the autumn of 1450, a few months after the King’s chief minister, the duke of Suffolk, fell from power. The indictments it took blamed the city’s recent difficulties on a corrupt alliance between the prior of Norwich and some of Suffolk’s retainers in East Anglia, who were accused of having oppressed the citizens.
Owing to gaps in the records, it is not clear exactly when Segryme became an alderman, but probably it was after he had finally completed his term as sheriff and before his election as mayor. He was an alderman for Conisford ward,
In April 1453, while Segryme was alderman of the guild, Margaret of Anjou visited Norwich (perhaps while on her way to the shrine at Walsingham to give thanks for her pregnancy), and he and other leading citizens lent the city money (in his case seven marks), so that it could prepare a suitable reception for her.
By the mid 1450s Segryme was feeling the effects of old age. In March 1455, after forgiving the city a debt of £20, he was excused from holding any civic office because of his physical infirmity. Evidently this exemption did not apply to his position as alderman, customarily an office for life, since he was re-elected as such later that month. He was dead by the following year, when John Burt was elected as an alderman in his place.
Some 16 years after Segryme’s death, the civic authorities agreed to give the hospital of St. Giles £200, drawn from the residue of his estate and that of his by then deceased executor, Richard Brown. In return for the gift, the hospital agreed to support a perpetual chaplain in St. Barbara’s, the chapel Segryme had helped to found.
