Sperk hailed from Tregony in the west of the county. He is first heard of in May 1419, when – styled a mere yeoman – he received a royal pardon for his failure to appear in court to answer charges of trespass brought against him by the justice Sir Robert Hill†.
Few other details of Sperk’s career have been discovered. He was present at the shire elections at Lostwithiel both in 1426, when he set his seal to the sheriff’s indenture, and in 1433, when he was one of the two men who found surety for the attendance of the knights of the shire.
