More may be added to the earlier biography.
Mitchell’s trading activities as a fishmonger probably provide the background to charges respectively brought before the justices of common pleas in Hilary term 1426 by Thomas Salman and in Easter term 1427 by the earl of Arundel’s representatives, John Burgh†, William Ryman*, Walter Urry*, Thomas Hayton, Richard Wakehurst† , John Payn and William Okehurst*, that a group of men clearly thought to have been acting on Mitchell’s behalf had stolen large quantities of fish from their private fisheries at Imworth and Thames Ditton in Surrey and – presumably in the course of this illicit activity – had blocked the watercourse to their respective mills at Imworth and Esher.
As well as being a wealthy heiress in her own right, Mitchell’s third wife was also the widow of a Buckinghamshire man named Nicholas Wolbergh. Some of her dower lands at Nutfield in Surrey were held from one of the leading landowners in the home counties, Nicholas Carew† of Beddington, with whom the Mitchells came into conflict in 1427 over the livestock he had seized in distraint for unpaid rents.
By his later years, Mitchell had acquired substantial landholdings in the home counties and beyond. In 1436 his holdings in Surrey, Hertfordshire, Cambridgeshire and Northamptonshire were valued at some £50 p.a.
