In Michaelmas term 1419 Lancaster was a plaintiff in the court of common pleas, in a suit in which he and several other Mowbray retainers alleged that William Lede*, the town clerk of Chichester, had unjustly detained £40 belonging to them.4 CP40/635, rot. 49. An account of Mowbray’s receiver-general provides further evidence of the trust in which Lancaster was held by his patron. Covering the accounting year 1420-1, it shows that the earl’s young son and several Mowbray wards (including John Bellers*) were then living in the MP’s household, presumably at Bressingham.5 L.E.
