Lower came from a family resident in the parish of St. Winnow since the fourteenth century or before.
As an important duchy official, Lower was a man of considerable standing in the duchy’s south-western headquarters, the borough of Lostwithiel, where he appears to have dwelt ‘atte Briggesende’,
Lower’s reasons for seeking election to the Commons in 1432 cannot be established beyond reasonable doubt, but it is possible that personal motives played a part, for in the early months of that year he was being sued in the court of common pleas by Isabel, the widow of another John Wyse, for breaking into her house in the London parish of St. Margaret Moses and stealing jewels worth £40, including ten gold rings and a gold rosary. Lower denied these charges, but nevertheless saw fit to appear in court in person.
The date of Lower’s death has not been discovered. He is last recorded as deputy clerk of the staple in August 1460, but it is not clear whether he was still alive at Michaelmas, when his son and heir, Nicholas, was appointed duchy havener in Cornwall. Nicholas, who attested the Cornish shire elections of 1467, later went on to serve in his father’s former office as clerk of the staple at Lostwithiel.
