Like many other of Leominster’s MPs, Mallyng, a clothier or draper, was involved in the cloth trade on which his native borough’s prosperity depended. He was probably the son of another John Mallyng: in 1426 this elder John, described a husbandman, was sued by the borough’s overlord, the abbot of Reading, for close-breaking at nearby Winsley; and in 1436, described as ‘senior’, he narrowly escaped outlawry at the suit of the abbot’s bailiff, Richard Winnesley*, for leaving Winnesley’s service at Winsley without licence.
Mallyng sat on the Leominster jury in both August 1452 and April 1457, when royal commissioners came to Hereford to investigate the county’s involvement in Yorkist risings. On the latter occasion, when he headed the jury, he took advantage of his position to secure the indictment of a Welsh yeoman from Bishop’s Castle, who, on the previous 26 Nov., had allegedly stolen cloth worth as much as £20 from his house at Leominster.
