Brown’s paternal grandmother, Maud, inherited from her nephew Robert Aleyn (d.1411) property in the Berkshire hamlets of South Moreton, Fulscot, Long and Little Wittenham and Sugworth by Bagley Wood, valued at just over £7 p.a. at Aleyn’s post mortem, and took them in marriage to her second husband, the much-married William Stokes.
Brown made proof of age at Wallingford on 15 Dec. 1444. One juror remembered his date of birth as he had long resented the fact that the child’s father had excused himself from paying a debt of £1 on account of the expenses of the baptism.
It may have been in order to pursue his claim in the courts that Brown sought election to the Parliament summoned for November 1449. He was returned for Wallingford, only about four miles from his home. It is likely that he was well known there, for he held Fulscot of the honour of Wallingford and inquests had been conducted in the town regarding his mother’s post mortem and his own proof of age. During the Easter term of 1450, while the Parliament was in session at Leicester, he continued his suits in the common pleas, and the Ormesbys brought a counter-action against him, claiming that he had illegally disseised them of Great Purley, which they said had been formally settled on Mercy and her former husband Carew and their issue. Brown, appearing by attorney, denied the charge. Later imprisoned in the Marshalsea, he secured his release on bail in Hilary term 1451 by entering bonds in £100 to keep the peace towards Mercy’s stepson, another Nicholas Carew*. Various postponements took the case to November that year, and although in the meantime Brown was occasionally called ‘of Great Purley’, and may have been in possession of the manor for a while, he proved unable to make good his claim. The Carews completed further settlements regarding the manor in 1454, and in February 1455 Carew was acquitted at his trial for entering the manor by force and ejecting Brown.
Brown apparently made similar attempts to gain other parts of the former Huscarle estate. In Hilary term 1451 as ‘of Great Purley, gentleman’ he was attached to answer John and Joan Iwardby in a plea alleging that the previous July, using stakes and stones, he had obstructed the flow of the Thames at Mapulderham Gurney so it failed to serve the mill which they held by descent from Sir Thomas Huscarle. The river remained blocked for six months or more. How the dispute was resolved is not known, although in October 1452 Brown, now called ‘esquire’, entered recognizances to Iwardby in 20 marks.
