More may be added to the earlier biography.
Mate was a feoffee for Ellen Brokholes, the mother-in-law of John Sumpter*, his fellow burgess in the Parliament of 1423. As such, he became involved in the long and bitter property dispute between Sumpter and Robert Arneburgh, who had married Sumpter’s sister-in-law, the other of Ellen’s two daughters by the Essex knight Sir Geoffrey Brokholes. It was a keenly contested quarrel because Ellen’s offspring and their issue were the heirs to the estates that she and Sir Geoffrey had held in Essex, Hertfordshire and Warwickshire. In the late 1420s, probably while bailiff, Mate received a letter from Arneburgh, who complained about the arrest at Colchester of his relative, the priest Ralph Beauchamp. The ‘burning of houses’ was the stated cause of the arrest, but it is likely to have been connected with the dispute. In a partisan account of the quarrel drawn up after Mate’s death it was asserted that he and two fellow burgesses, William Nottingham I* and Thomas Godstone*, had used the borough’s seal to authenticate a document supporting Sumpter. The account adds that God had shortened their lives to punish them for ‘theyre vntrue labour’ on Sumpter’s behalf.
The previous biography wrongly states that Mate died in 1449, for he was already dead when his widow Eleanor brought a deed into the borough court for enrolment on 1 July 1445.
