(BIO) Sir John Gardiner of Warwick (fl. 1405–1435):

 

Sir John Gardiner of Warwick (fl. 1405–1435): Steward of Worcestershire and Gloucestershire estates, knighted circa 1415. As receiver-general to Richard Beauchamp, he held Elmley Castle and Peopleton in chief (CR 162/45, grant dated 1418). His audits masked wool exports during the earl's Calais captaincy (1414–1421), chaining directly to our later Hanse alliances.
