Although nothing is known for certain about this MP’s early life and ancestry, it seems likely that he grew up in Yorkshire, where the Mauleverer family was particularly influential, providing the county with several administrators and government officials during the period here under review. He himself is first mentioned in April 1386, when he obtained royal letters of protection pending his departure overseas in the company of Sir Thomas Trivet, admiral of the west. One year later he was pardoned a sentence of outlawry incurred for his failure to appear in court and defend himself in an action for debt brought against him by the wealthy London draper, John Hende, who claimed to be owed £32.
Mauleverer soon established himself as a prominent figure in county society, and he acted fairly regularly as a witness to the property transactions of his neighbours. He performed this service for John Culpepper and his kinsmen, the Greens, Sir Thomas Burton and William, Lord Zouche, all of whom exercised considerable authority in the Rutland area.
