Hyrne’s father, who served as sheriff of Norwich in 1575 and mayor in 1593, was a grocer and member of the Norwich Fishmongers’ Company.
In 1610 Sir John Heveningham* entered a bill in Parliament to confirm his purchase of Lowestoft manor from Hyrne, thereby breaking various entails.
Hyrne was a trustee of the Paston estate from 1619.
