This obscure shire knight may have been related to the John Ormesby who served as a buyer for the royal household in 1365, but his background and parentage are now unknown. His name suggests a possible connexion with Ormsby in Lincolnshire; and, indeed, in March 1387 he stood surety for two persons from the diocese of Lincoln who were appealing against the bishop’s orders for their excommunication.
Ormesby died between the early summer of 1400 and 22 Jan. 1401, leaving his widow, Eleanor, and a chaplain named Hugh Brymbre to implement the terms of his will. He bequeathed his armour to the prior of Clerkenwell, but wished to be buried at the parish church of Cranford in Middlesex.
