Neville married one of five co-heiresses to an Essex landowner (another of whom later married Sir Henry Vane*), and consequently he acquired 290 acres when the estate was divided up in 1608.
Neville was named to only two committees in the Addled Parliament. On 16 May he was among those appointed to consider the bill to endow Sackville College at East Grinstead in accordance with the will of his kinsman the 2nd earl of Dorset (Robert Sackville*). A week later he was among those instructed to report on the recently created order of baronetcy.
Chamberlain reported the speech as ‘a curious premeditate declamation made for some other time’, while Sir Henry Wotton*, who had earlier in the Parliament defended impositions, facetiously and inaccurately dismissed it as a Latin exercise by ‘a young gentleman, fresh from the school’.
In the winter of 1616 Neville fell victim to the ‘extreme jealousy’ of Sir Humphrey Tufton†, the brother of Sir Nicholas* and Richard*, for his ‘civil and respective love’ to Lady Tufton, a kinswoman and former neighbour. Tricked into coming secretly ‘and in scurvy clothes’ to Tufton’s house in Lincoln’s Inn Fields, he was set upon by half a dozen bullies ‘in an Italian manner’ and soundly beaten. John Chamberlain thought that ‘the matter was ill carried on both sides’, but the 3rd earl of Dorset and his brother Sir Edward Sackville* gave evidence in Star Chamber for Neville, who was awarded £500 damages.
In 1620 Neville was promised a nomination at Dover by the lord warden of the Cinque Ports, Edward, 11th Lord Zouche,
On 12 Feb. 1621 Neville moved to recommit the address for freedom of speech in Parliament, and was named to the drafting committee.
Neville was appointed to the sub-committee for receiving petitions established by the committee for courts of justice on 21 February. Consequently he may have been one of the first Members to become acquainted with the accusations of accepting bribes levelled against the lord chancellor (Sir Francis Bacon*).
On 15 Mar. Neville was named to the committee for the bill to establish a new trust for the estates of Anthony, 2nd Viscount Montagu, a relation by marriage of the Sackvilles, and he attended one undated meeting.
Neville attended a meeting of the committee to regulate Chancery, to which he had been appointed on 25 Apr., and was also among those named to inquire into the government of Ireland (26 Apr.) and to draft a bill against judicial corruption, favouritism, and excessive fees (27 April). On 2 May he was added to the committee for surveying grievances.
Neville’s father died in 1622 and, in accordance with his will, Neville inherited property in Somerset, including the manor of Newton St. Loe, where he resided in the latter part of his life. The following year he purchased Sheffield Park in Sussex from the 3rd earl of Dorset for £3,000.
Neville carried ‘the standard of the Lion of England’ at the funeral of James I.
Unlike his elder brother, Neville seems to have been a loyal adherent of the Church of England, and in 1635 he was ordered to provide for the Protestant education of a Gloucestershire youth who had hitherto been trained up under a priest.
